Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present description. This description may be embodied in many other forms than described herein and similarly generalized by those skilled in the art to whom this disclosure pertains without departing from the spirit of the disclosure and, therefore, this disclosure is not limited by the specific implementations disclosed below.
The terminology used in the one or more embodiments of the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the one or more embodiments of the specification. As used in this specification, one or more embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used in one or more embodiments of the present specification refers to and encompasses any or all possible combinations of one or more of the associated listed items.
It should be understood that, although the terms first, second, etc. may be used in one or more embodiments of this specification to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of one or more embodiments of the present description. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
First, terms related to one or more embodiments of the present specification will be explained.
Internetworking protocol (IP, internet Protocol): is a network layer protocol in the TCP/IP architecture. Wherein, TCP/IP (Transmission Control Protocol/Internet Protocol ) refers to a protocol cluster capable of implementing information transmission between multiple different networks. The IP has the function of improving the expandability of the network and realizing the interconnection and intercommunication of large-scale heterogeneous networks. IP is a foundation constituting the internet, and can provide various protocols of information, such as TCP, UDP, etc., to a transport layer; IP packets may be placed on the link layer for delivery via various technologies such as ethernet, token ring networks, etc.
IP network: the connected network is implemented in accordance with an internetworking protocol. For example, communication between different networks, such as ethernet, packet switched networks, etc., may be implemented in accordance with an internetworking protocol.
IP conversion: refers to converting various types of data (analog signal data, digital signal data, etc.) into IP packets conforming to the internet protocol. The IP packets may be transmitted based on a general internet infrastructure (such as a router, a switch, a communication network, etc.), and stored in a general storage device (such as a usb disk, a hard disk, a mobile hard disk, a network attached storage, etc.). Network attached storage (NAS, network Attached Storage): a device connected to a network and having a data storage function is also called a "network storage". NAS is a dedicated data storage server, which uses data as a center, thoroughly separates storage devices from the server, and centrally manages data, thereby freeing bandwidth, improving performance, and reducing total ownership cost.
Digital component serial interface (SDI, serial Digital Interface): a digital video interface standard. The interface of the SDI is mainly determined according to a transmission rate, for example, the HD-SDI interface is a high definition digital input and output port of a broadcasting stage, where HD represents a high definition signal. The SDI serial interface is an interface that sequentially transfers bits of a data word and corresponding data through a single channel. Since the data rate of serial digital signals is high, it must be processed before transmission. Since the SDI interface cannot directly transmit the compressed digital signal, after the compressed signal recorded by the digital video recorder, the hard disk, and other devices is replayed, the compressed signal must be decompressed and output through the SDI interface to enter the SDI system. If decompression and compression are repeated, it is necessary to cause degradation of image quality and increase of delay, and for this purpose, digital video recorders and nonlinear editing systems of various formats, which define their own interfaces for directly transmitting compressed digital signals, are provided.
Network device Interface (NDI, networkDevice Interface): audio and video codec and UDP based network transport protocol interfaces. NDI does not require complex wiring to reliably transmit and store conventional video signals in an IP network-based infrastructure. NDI can implement two functions, a first one being encoding compression and decoding of video and a second one being low-latency transmission based on the first one. Wherein, the encoding and decoding of NDI may include: the coding is to code the audio and video signals into NDI network flow to enter the exchanger or PC, then to be found and called by PC or software in the network; in the decoding process, the NDI is controlled to decode and restore NDI streams (NDI streams are selected when more NDI streams are needed) in the network into SDI/HDMI signals by decoding and restoring 1-path NDI streams only through one NDI box, and the SDI/HDMI signals are output to a local display, television, recorder or other equipment or terminals requiring SDI/HDMI signals through the NDI box. HDMI refers to a high definition multimedia interface (High Definition Multimedia Interface, HDMI) which is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals. HDMI can be used for set top boxes, DVD players, personal computers, televisions, game consoles, combination expansion machines, digital audio and television sets, and other devices. HDMI can send audio frequency and video signal simultaneously, because audio frequency and video signal adopt same wire rod, can simplify the installation degree of difficulty of system's circuit greatly.
Agent material: and the original video material is replaced by the agent material with smaller data volume and unchanged content through automatic transcoding and calling of the agent software. On the basis, the agent materials can be clipped, the clipping result is applied to the large video materials, and finally the target video which does not affect the video quality is output.
And (3) image transmission: the image is accurately and quickly transferred. The current common graphic transmission technologies are MPEG-2, MPEG-4, etc., and in brief, the technologies are to compress the emphasis of the image and grasp the emphasis transmission.
Metadata (Metadata): also called intermediate data and relay data, which are data (data about data) describing data, mainly describe information of data attribute (property) and are used for supporting functions such as indicating storage location, history data, resource searching, file recording, etc. Metadata is an electronic catalog, and in order to achieve the purpose of cataloging, the contents or characteristics of data must be described and collected, so as to achieve the purpose of assisting in data retrieval.
Referring to fig. 1, fig. 1 shows an exemplary diagram of a video processing flow in a film-shooting scene, which may specifically include the following steps: a post-editing process and a field shooting process. The field shooting process comprises the following steps: the video camera collects videos, the videos are sent to the image transmission end through the SDI cable, the image transmission end sends the videos to the image transmission receiving end through wireless transmission, the image transmission receiving end sends the videos to the site monitor through the SDI cable, and then site related personnel can monitor and review the shot videos through the site monitor. The later clipping flow includes: writing the video acquired by the camera into a memory card during shooting, taking out the memory card from the camera after the acquisition is completed, and copying the memory card and acquiring proxy materials; the copying refers to reading video from a memory card, and the agent material acquisition refers to automatic transcoding and calling of the read video through agent software to obtain agent material; further, storing the video obtained by copying, namely the original material and the proxy material, into an NAS storage matrix; editing personnel can acquire agent materials and original materials from the NAS storage matrix; editing the proxy material, and sleeving the editing result back to the original material to obtain a sheet. In the video processing flow shown in fig. 1, video processing such as editing, manual transfer and transcoding depending on a memory card, and operation can be performed only after shooting is completed, and cannot be performed in parallel with movie and television drama shooting, resulting in low video processing efficiency.
In order to improve video processing efficiency, in the present specification, a video processing method is provided, and the present specification relates to a video processing apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Referring to fig. 2, fig. 2 shows a flowchart of a video processing method according to an embodiment of the present disclosure, which is applied to a transcoding unit, and specifically includes the following steps:
s202, acquiring an original video acquired by a camera in the video acquisition process of the camera.
In a specific application, the transcoding unit is connected to the camera. The specific manner of connection may be varied depending on the specific form of the transcoding unit. For example, when the transcoding unit is a software module, the transcoding unit may be provided in an output port of the camera or in a network interface of a communication network communicating according to the internet protocol, which network interface is connected to the camera. Alternatively, for example, when the transcoding unit is a hardware device, the transcoding unit may be independent of the camera and the above-mentioned communication network, and connected to the camera and the above-mentioned communication network, respectively. And, the video capturing process by the camera may include: the camera starts the video acquisition to the process before the video acquisition is finished. Therefore, the step S202 can achieve the effect of immediately acquiring the video acquired by the camera: when the video is acquired by the camera, the currently acquired video is acquired without waiting for the video acquisition to finish. In this way, video processing efficiency can be ensured. The transcoding unit can acquire the original video acquired by the camera in the video acquisition process of the camera in various modes.
In an alternative embodiment, the output interface of the camera is connected to a network device interface of the communication network, wherein the network device interface comprises a transcoding unit;
correspondingly, the method for acquiring the original video acquired by the camera specifically comprises the following steps:
receiving an original video acquired by a camera by using a network equipment interface;
the original video is input to a transcoding unit.
The network device interface may specifically be NDI. In this way, an NDI in the form of a hardware device, i.e. an encoder, can be directly connected to the camera in an external manner, and the SDI output of the camera, i.e. the original video, is received. Further, NDI IP-converts received data by the included transcoding unit: the original video in the form of an SDI signal is transcoded into transcoded video data in the form of an NDI signal. Therefore, the embodiment realizes the acquisition and transcoding of the original video through the NDI in the form of hardware equipment, and does not need to additionally set codes for transcoding the video according to an Internet protocol, thereby being more convenient.
For example, the camera may actively output the captured video to the transcoding unit when the video is captured, so that the transcoding unit may receive the video, i.e., the original video. Alternatively, the transcoding unit may request the video captured by the camera during a preset period from the camera when it is monitored that the camera starts capturing the video, so that the transcoding unit may receive the original video. This is reasonable, and any manner of obtaining the original video collected by the camera during the video collection of the camera can be used in the present specification, which is not limited in this embodiment.
S204, transcoding the original video according to the Internet protocol to obtain transcoded video data with the data format conforming to the Internet protocol.
In a specific application, the original video is transcoded according to the internet protocol to obtain transcoded video data with a data format conforming to the internet protocol, and the original video is IP-formatted to obtain IP packets capable of being transmitted in a communication network communicating according to the internet protocol. In this embodiment, the IP data packet is transcoded video data, so that it can be ensured that the transcoded data can be uploaded to the communication network and obtained by the video processing device accessing the communication network. Also, the IP packet may be applicable to video processing devices, such as mobile terminals, portable notebooks, desktop computers, and the like.
In contrast to SDI transmitted data, the original video captured by the camera may no longer be limited to only the receipt by a monitor at the theatrical scene, but may be received and processed by a video processing device. In one case, the transcoding unit may also obtain metadata of the original video in order to ensure that the subsequent video processing is more accurate based on the video processing of the transcoded video data. This will be described in detail in the following in the form of alternative embodiments for ease of understanding and rational layout.
And S206, uploading the transcoded video data to a communication network which communicates according to an Internet protocol.
In particular applications, the communication network may be a plurality of communication networks communicating according to the internet protocol. The communication network may be, for example, a wireless communication network: WIFI networks, local area networks where cameras are located at video capture sites, ethernet, etc. In one case, the communication network communicating according to the internet protocol is a target wireless communication network; accordingly, after the transcoding unit uploads the transcoded video data to the target wireless communication network, the target wireless communication network may broadcast the transcoded video data.
The target wireless communication network may be a WIFI network where the video camera is located on the video shooting site, and in this embodiment, the NDI signal, that is, the transcoded video data, may be broadcast and output in the WIFI network. In this way, no additional connection means, such as signal transmission lines or the like, between the communication network and the acquisition of the transcoded video data are required. In addition, the access of the WIFI network can be increased in authority, so that the WIFI network can be directly broadcasted, and the WIFI network is more convenient and efficient. In this way, by the IP conversion of the original video, the transcoded video data can be applied to the video processing device, and compared with the video data transmitted directly through the image transmission module for realizing image transmission, the problem that the transmitted data can be only identified by industrial professional devices such as monitors and the like, but is identified by video processing devices such as computers, mobile phones and the like can be avoided.
In one embodiment of the present disclosure, the transcoding unit transcodes the original video collected by the camera into transcoded video data conforming to the internet protocol, and the data conforming to the internet protocol has versatility. Thus, it can be ensured that the transcoded video data is suitable for a computing device such as a video processing device. On the basis, the transcoded video data is uploaded to a communication network which communicates according to an Internet protocol, and computing equipment such as video processing equipment and the like do not need to wait for a camera to finish video acquisition and complete reading of an original video from a storage medium of the camera, but can directly acquire the transcoded video data from the communication network in the video acquisition process, so that video processing is performed based on the transcoded video data. Therefore, the video processing efficiency can be improved by the scheme.
In an alternative implementation manner, before uploading the transcoded video data to the communication network that communicates according to the internet protocol, the video processing method provided in the embodiment of the present specification may further include the following steps:
receiving an original video acquired by a camera, and extracting metadata of the original video;
transcoding the metadata according to the Internet protocol to obtain transcoded element data with a data format conforming to the Internet protocol;
Accordingly, the uploading of the transcoded video data to the communication network communicating according to the internet protocol may specifically include the following steps:
the transcoded video data and the transcoded symbol data are uploaded to a communications network that communicates according to an internetworking protocol.
In a specific application, metadata of an original video is used to describe attribute information of the original video. In this embodiment, in order to ensure that the transcoded video data can be used to process the transcoded video data into proxy material, the attribute information described by the metadata of the original video may include: information characterizing the uniqueness of the original video, information characterizing the relationship between each video frame in the original video and the duration of the video, and the like. For example, the information characterizing the uniqueness of the original video may be a name of the original video, and the information characterizing the relationship between each video frame and the video duration in the original video may be a time code of the original video. For example, video frame F1 should correspond to video duration 10 seconds. In addition, in order to ensure that the metadata can be transmitted and used, the metadata is transcoded, similar to the original video, to obtain transcoded symbol data with a data format conforming to the internet protocol. In a scenario where the transcoding unit is included in NDI, in order to implement the present embodiment, a module for extracting metadata of an original video may be provided in NDI. And, the NDI may be configured to transcode metadata according to an internet protocol.
In this way, in a scenario that the output interface of the camera includes the image transmission module to improve the image transmission efficiency, the embodiment can ensure that the data uploaded to the communication network includes the complete metadata of the original data, so as to reduce the metadata loss of the original video caused by image transmission, thereby causing the problem that the proxy material cannot be obtained later.
In an alternative embodiment, before the original video acquired by the camera is acquired, the video processing method provided in the embodiment of the present disclosure may further include the following steps:
acquiring transmission bandwidth of a communication network and bandwidth occupation amount of a camera;
determining the load quantity matched with the transmission bandwidth based on the transmission bandwidth and the bandwidth occupation quantity;
according to the number of loads, connections with a plurality of cameras are established.
In a specific application, the number of loads matched with the transmission bandwidth is determined based on the transmission bandwidth and the bandwidth occupation amount, so that the number of a plurality of cameras connected in a subsequent establishment can be ensured, and the number of the cameras can be matched with the transmission bandwidth of the communication network. Therefore, under the condition of accessing a plurality of cameras, the accessed load quantity is prevented from exceeding the load capacity of the communication network, and the normal operation of the communication network and the cameras is ensured. And in the process of establishing the connection with the plurality of cameras according to the number of loads, the number of the plurality of cameras is smaller than or equal to the number of loads. Therefore, the transcoding unit is used for controlling the access of a plurality of cameras, compared with the video processing flow shown in fig. 1, the transcoding unit does not need to additionally configure equipment in an existing shooting flow every time one camera is added, the convenience of video processing can be greatly improved, and the equipment cost is reduced.
Referring to fig. 3, fig. 3 is a flowchart of another video processing method provided in an embodiment of the present disclosure, which is applied to a video processing device accessing a communication network, where the communication network communicates according to an internet protocol, and specifically includes the following steps:
s302, receiving transcoding video data sent by a transcoding unit through a communication network, wherein the transcoding video data is obtained by transcoding an original video acquired by a camera according to an Internet protocol in the process of video acquisition by the transcoding unit.
In a specific application, the process of the transcoding unit obtaining the transcoded video data and the communication network in this embodiment are the same as the process of the transcoding unit obtaining the transcoded video data and the communication network in the embodiment of fig. 2, respectively, and are not described in detail herein. Also, the video processing device may be various, for example, the video processing device may be a mobile terminal, a desktop computer, a portable computer, or the like. The manner in which the video processing apparatus receives the transcoded video data sent by the transcoding unit via the communication network may be various. In an alternative embodiment, the communication network is a target wireless communication network;
Correspondingly, the receiving, through the communication network, the transcoded video data sent by the transcoding unit may specifically include the following steps:
and receiving the transcoded video data broadcasted by the target wireless communication network, wherein the transcoded video data is uploaded to the target wireless communication network by the transcoding unit.
The target wireless communication network may be a WIFI network where the video camera is located on the video shooting site, and in this embodiment, the NDI signal, that is, the transcoded video data, may be broadcast and output in the WIFI network. In this way, no additional connection means, such as signal transmission lines or the like, between the communication network and the acquisition of the transcoded video data are required. In addition, the access of the WIFI network can be increased in authority, so that the WIFI network can be directly broadcasted, and the WIFI network is more convenient and efficient.
S304, obtaining video processing data based on the transcoded video data.
In a specific application, the video processing data is data obtained by processing the transcoded video data, and may be various. For this reason, the manner in which video processing data is obtained based on transcoded video data may be various. Illustratively, the transcoded video may be decoded according to an internet protocol, and the original video obtained by decoding is used as video processing data. Alternatively, for example, metadata extraction may be performed on the transcoded video data, the transcoded video data may be compressed, and the compressed transcoded video data and metadata, that is, proxy material, may be used as video processing data. On this basis, efficient video editing can be performed using proxy material. Alternatively, illustratively, the transcoded video may be decoded in accordance with the internet protocol, and the original video obtained by decoding may be subjected to toning, editing, and so forth. In addition, the video processing device can directly clip the proxy material, and further, the clipping result is sleeved back to the original video obtained after decoding, so that the target video such as cost is obtained. Alternatively, the video processing device described above may send the proxy material and transcoded video data to a dedicated video editing device, which clips the video to obtain the target video. The agent material can be sent after transcoding according to the internet protocol.
In one case, in a scenario where the output interface of the camera includes a graphics module to improve the image transmission efficiency, the original video is a video that is compressed by graphics, so that metadata is likely to be missing, and a problem that the proxy material obtained later is inaccurate and cannot be used for video editing is also caused. In this regard, in an alternative embodiment, the video processing data includes target agent material for a video clip;
accordingly, before obtaining video processing data based on the transcoded video data, the video processing method provided in the embodiments of the present disclosure may further include the following steps:
receiving metadata of the transcoded video data sent by the transcoding unit through a communication network;
accordingly, obtaining video processing data based on the transcoded video data may specifically include the steps of:
decoding the transcoded video data, compressing the data quantity of the decoding result, and taking the compressed transcoded video data and metadata of the transcoded video data as target agent materials.
Illustratively, the original material is a material with a resolution of 4K, the file name of the original material is c001.Mp4, the video duration is 10 seconds, and the time code is 90001000 to 90011000. Then, the target agent material may include: the decoding result is compressed to obtain 1080P resolution material with a file name of C001-proxy.mp4, the video duration is 10 seconds, and the time codes are 90001000 to 90011000. The time code refers to corresponding marks of the video frames and the video time length of the material, so that dislocation of the video frames can be prevented. For example, the time code 90001000 represents the 1 st second corresponding video frame F0.
