In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a block schematic diagram of a double-buffer encoding system according to an embodiment of the present invention, as shown in fig. 1, which includes a production module 10, a consumption module 20, and two buffer modules 30.
Wherein the production module 10 and the consumption module 20 are respectively connected with one of the two buffer modules 30;
when the queue corresponding to the buffer module 30 connected to the production module 10 has reached the threshold value and the queue corresponding to the buffer module 30 connected to the consumption module 20 is empty, the production module 10 and the consumption module 20 exchange the buffer modules 30 respectively connected thereto.
That is, during the transcoding process, the production module 10 and the consumption module 20 are respectively connected to a buffer module 30; the buffer module 30 is connected with the production module 10 and used for storing production data produced by the production module 10; when the queue corresponding to the buffer module 30 connected to the production module 10 has reached the threshold value and the queue corresponding to the buffer module 30 connected to the consumption module 20 is empty, the production module 10 and the consumption module 20 exchange the buffer modules 30 connected to each other; after the exchange, the production module 10 may store the production data obtained by its own production through the empty buffer module 30, and the consumption module 20 may acquire the production data stored in the buffer module 30 connected to itself for consumption, in the encoding process, the locking and unlocking operations are not required, and the encoding process does not have an asynchronous problem; the transcoding efficiency can be greatly improved.
In some embodiments, the production module 10 is configured to perform production to obtain production data and store the production data in the buffer module 30 connected thereto; when the queue corresponding to the buffer module 30 connected to the production module 10 has reached the threshold, the production module 10 obtains the queue information corresponding to the buffer module 30 connected to the consumption module 20, and determines whether the queue corresponding to the buffer module 30 connected to the consumption module 20 is empty according to the queue information; if so, the production module 10 and the consumption module 20 interchange the respectively connected buffer modules 30; if not, the production module 10 enters a wait state until the queue corresponding to the buffer module 30 connected to the consumption module 20 is empty.
In some embodiments, the consumption module 20 is used to consume the production data 10 stored in the buffer module 30 connected thereto; when the queue corresponding to the buffer module 30 connected to the consumption module 20 is empty, the consumption module 20 obtains queue information corresponding to the buffer module 30 connected to the production module 10, and judges whether the queue corresponding to the buffer module 30 connected to the production module 10 has reached a threshold value according to the queue information; if so, the production module 10 and the consumption module 20 interchange the respectively connected buffer modules 30; if not, the consuming module 20 enters a wait state until the queue corresponding to the buffer module 30 to which the producing module 10 is connected has reached the threshold.
That is, the threads of the production module 10 and the threads of the consumption module 20 are independent of each other.
As an example, in the encoding process, whether the interchange condition of the buffer module 30 is reached may be judged by the production module 10; that is, the consuming module 20 enters a waiting state when its corresponding buffer module 30 is empty; when the queue corresponding to the buffer module 30 connected to the production module 10 reaches the threshold, the production module 10 acquires the queue information corresponding to the buffer module 30 connected to the consumption module 20 to determine whether the buffer module 30 is empty; in other words, whether or not the buffer module 30 interchange is possible is entirely determined by the production module 10.
As another example, in the encoding process, whether the interchange condition of the buffer module 30 is reached may be judged by the consumption module 20; that is, the production module 10 enters a waiting state when the queue corresponding to the buffer module 30 connected thereto reaches a threshold; the consuming module 20 obtains the queue information corresponding to the buffer module 30 connected to the producing module 10 only when the queue corresponding to the buffer module 30 connected to the consuming module is empty, so as to determine whether the interchange condition is met; in other words, whether or not the buffer module 30 interchange is possible is entirely determined by the consumption module 20.
As yet another example, both threads may make a determination of whether the interchange condition is reached; that is, when the queue corresponding to the buffer module 30 connected to the production module 10 reaches the threshold, it is determined whether the buffer module 30 connected to the consumption module 20 is empty; when the buffer module 30 connected to the consuming module 20 is empty, it is determined whether the queue corresponding to the buffer module 30 connected to the producing module 10 has reached the threshold.
It should be noted that there may be various ways to set the threshold of the queue corresponding to the buffer module 30 connected to the production module 10. For example, whether the queue has reached a threshold; alternatively, the amount of data in the queue may reach 60%. When the buffer module 30 connected to the production module 10 stores the ending identifier, the queue is considered to have reached the threshold.
In summary, the double-buffer coding system according to the embodiment of the present invention includes: the system comprises a production module, a consumption module and two buffer modules, wherein the production module and the consumption module are respectively connected with one of the two buffer modules; when the queue corresponding to the buffer module connected with the production module reaches a threshold value and the queue corresponding to the buffer module connected with the consumption module is empty, the production module and the consumption module exchange the buffer modules connected with each other; therefore, the asynchronous problem can not occur in the process of completing video transcoding through multiple threads; meanwhile, the video transcoding efficiency is improved, and the waiting time of a user is reduced.
