The video information is obtained in the above mode, so that the accuracy and reliability of the video information determination are effectively ensured, and the accuracy degree of the method is further improved.
FIG. 4 is a flowchart illustrating adjusting a thumbnail of a video sequence frame in video information displayed in a video editor according to a triggering operation according to an embodiment of the present invention; as can be seen from fig. 4, the adjusting of the thumbnail of the video sequence frame in the video information displayed in the video editor according to the triggering operation in the embodiment may include:
s1031: if the playing time period is prolonged relative to the historical playing time, the number of thumbnails of video sequence frames in the video information displayed in the video editor is increased; or,
s1032: if the playback time period is shortened relative to the historical playback time, the number of thumbnails displaying video sequence frames in the video information in the video editor is reduced.
The historical playing time is the time before the user drags the video editor, and the historical playing time can be less than or equal to the preset standard playing time, and the standard playing time is the time required to process the complete video including the video information.
For example, the historical playing time corresponding to a certain video is T1, at this time, the number of thumbnails displayed in the video editor is N1, after the user drags the video editor, it is possible to determine certain video information in the video and the playing time period T2 corresponding to the video information, at this time, the number of thumbnails displayed in the video editor is N2, and if T2> T1, N2> N1, that is, when the playing time period is extended with respect to the historical playing time, the number of thumbnails of video sequence frames displayed in the video editor is increased. Alternatively, if T2< T1, then N2< N1, i.e., the playback time period is shortened relative to the historical playback time, the number of thumbnails of video sequence frames displayed in the video editor may be reduced. If T2 is T1, N2 is N1, and when the playback time period is equal to the historical playback time, it is described that the playback time at this time has not changed, and therefore, the number of thumbnails of video sequence frames displayed in the video editor has not changed. In general, the number of thumbnails located in the video sequence frames displayed in the video editor is in a preset ratio to the time in the playback period.
It is to be understood that, after determining the play time period after dragging according to the triggering operation, the method further includes:
s201: if the playing time period is prolonged relative to the historical playing time, the number of thumbnails of video sequence frames in the video information displayed outside the video editor is reduced; or,
s202: if the playback time period is shortened relative to the historical playback time, the number of thumbnails of video sequence frames in the video information displayed outside the video editor increases.
Following the above description, for example, the historical playing time corresponding to a certain video is T1, the number of thumbnails displayed in the video editor is N3, and after the user drags the video editor, the video information in the video and the playing time period T2 corresponding to the video information may be determined, at this time, the number of thumbnails displayed in the video editor is N4, and if T2> T1, N4< N3, that is, the playing time period is extended with respect to the historical playing time, and the number of thumbnails of video sequence frames displayed outside the video editor is reduced. If T2< T1, N4> N3, that is, the playback period is shortened with respect to the historical playback time, the number of thumbnails of video sequence frames displayed outside the video editor increases. If T2 is T1, N4 is N3, and when the playback time period is equal to the historical playback time, it indicates that the playback time at that time has not changed, and therefore, the number of thumbnails of video sequence frames displayed in and outside the video editor does not change.
It is understood that, when adjusting the thumbnail of the video sequence frame in the video information displayed in the video editor according to the triggering operation, the size and/or display scale of the thumbnail displayed in the video editor may also be adjusted according to the triggering operation, for example: if the playing time period is prolonged relative to the historical playing time, the size/display proportion of the thumbnail of the video sequence frame in the video information displayed in the video editor is reduced; alternatively, if the playback time period is shortened with respect to the historical playback time, the size/display ratio of the thumbnail of the video sequence frame in the video information displayed in the video editor becomes large. Those skilled in the art can determine a specific implementation manner according to specific design requirements, as long as the thumbnail displayed in the video editor can be adjusted according to the trigger operation, which is not described herein again.
Fig. 5 is a schematic flowchart illustrating a process of acquiring a trigger operation of a user dragging a video editor according to an embodiment of the present invention; on the basis of the foregoing embodiment, with reference to fig. 5, when the user performs the dragging operation on the video editor, the specific implementation manner of the trigger operation acquisition in this embodiment is not limited, and those skilled in the art may set the trigger operation according to specific design requirements, and preferably, the trigger operation of acquiring the user dragging the video editor in this embodiment may include:
s1011: acquiring a first trigger operation of dragging a first adjusting area of a video editor by a user; and/or the presence of a gas in the gas,
s1012: and acquiring a second trigger operation of dragging a second adjusting area positioned in the video editor by the user, wherein the second adjusting area and the first adjusting area are positioned at two sides of the video editor.
For example, the video editor is located at the upper end or the lower end of the video to be processed, and the video editor is a strip-shaped editing frame capable of editing, where the editing may be an editing operation in which a user drags the video editor left and right, at this time, the first adjustment area and the second adjustment area may be located on the left and right sides of the video editor respectively, and the user may drag the first adjustment area, so that the first adjustment area may move left and right, and the first trigger operation may be acquired; similarly, the second adjustment area may also move left and right according to the dragging operation of the user, and then the second trigger operation may be obtained.
In order to improve the display effect of the human-computer interaction, the method may further include:
s201: when the user drags the first adjustment area, the first adjustment area can move according to the dragging track of the user and restore to the preset initial position after the dragging is finished.
For example, the initial position of the first adjustment region is L1, when the user drags the first adjustment region, the first adjustment region may move according to the dragging operation of the user, and when the position where the dragging operation of the user ends is L2, the first adjustment region may be restored from the position L2 to the position L1 after the dragging operation of the user ends, thereby achieving the effect that the first adjustment region has a rebound effect when the user ends the dragging operation, and further improving the display effect of human-computer interaction.
Similarly, the method further comprises:
s301: when the user drags the second adjustment area, the second adjustment area can move according to the dragging track of the user and restore to the preset initial position after the dragging is finished.
Similar to the implementation process of step S201, the description is omitted here.
In order to further improve the practicability of the method, the method in this embodiment may further include:
s401: displaying, with a video editor, time information corresponding to the video information, the time information including at least one of: a playing time period, a playing start time, and a playing end time.
The playing time period can be displayed through the middle area of the video editor, the playing start time can be displayed through one side (left side or right side) of the video editor, and the playing end time can be displayed through the other side (right side or left side) of the video editor to be distinguished from the playing start time.
In addition, when the video editor can display the playing time period, the playing start time and the playing end time, the playing time period displayed in the video editor can be changed in real time according to the triggering operation of dragging the video editor by a user, the playing start time displayed in the video editor can be changed in real time according to the triggering operation of dragging the first adjusting area on one side (for example, the left side) of the video editor by the user, and the playing end time displayed in the video editor can be changed in real time according to the triggering operation of dragging the second adjusting area on the other side (for example, the right side) of the video editor by the user; it can be understood that, when the user does not have a trigger operation on the first adjustment region or the second adjustment region, the play start time and the play end time corresponding to the first adjustment region or the second adjustment region do not change.
The time information corresponding to the video information is displayed by using the video editor, so that a user can intuitively acquire the time information related to video processing when the video is processed, and the convenience degree of the method is further improved.
Fig. 6 is a flowchart illustrating a video processing method according to another embodiment of the present invention; fig. 7 is a schematic flowchart illustrating a process of decoding image data by using a preset decoding manner according to an embodiment of the present invention; on the basis of the foregoing embodiment, with continued reference to fig. 6 to 7, in this embodiment, after determining the video information to be processed after dragging according to the trigger operation, the method further includes:
s501: acquiring image data corresponding to the video information;
s502: and decoding the image data by using a preset decoding mode to obtain a plurality of video sequence frames in the video information.
The preset decoding mode comprises a hard decoding mode and/or a soft decoding mode.
Specifically, decoding the image data by using a preset decoding manner may include:
s5021: decoding the video data by using a hard decoding mode;
s5022: if the video data can not be decoded by using the hard decoding mode, the video data is decoded by using the soft decoding mode.
The hard decoding (also referred to as hardware decoding) mode is a mode of decoding a video (high-definition video) by using a video acceleration function of a video card, the soft decoding (also referred to as software decoding) mode is a mode of decoding a video (high-definition video) by using a central processing unit CPU, and the API Media metadata receiver is taken as a hard decoding mode, and FFPG is taken as a soft decoding mode for example, first, decoding operation is performed on video data by using the hard decoding API Media receiver to realize API extraction on a video sequence frame; if the extraction is not available, the decoding operation is carried out on the video data through the soft decoding of the FFPG so as to realize the API extraction of the video sequence frame.
