In common video quality problems, it is a more serious video quality problems that sound, which is drawn asynchronous, therefore, this Inventive embodiments can after individually having been inspected to the first audio data and the first video data, to the first audio data and First video data synchronizes inspection, and the target video is examined to draw nonsynchronous problem with the presence or absence of sound.

Specifically, S205 may comprise steps of a and b:

A, each number of the timestamp of each data block based on first audio data and first video data According to the timestamp of block, timestamp sequence is determined；

It will be appreciated by persons skilled in the art that the timestamp of the data block of the first audio data is audio encoding process The play time of the audio data block of middle record, the timestamp of the data block of the first video data are recorded in video coding process Video data block play time.Under normal circumstances, obtain a data block time, with the data block correspondent time when Between be consistent.

Wherein, the process of target video is obtained, is the different data block for successively getting target video, these data in fact There is audio data block in block, also there is video data block, all audio data blocks constitute the first audio data, all video counts The first video data is constituted according to block.It is possible to understand, the target video got is one in fact about data block First ray, the First ray are as follows: each data block and the first video counts of the first audio data are arranged according to acquisition time According to each data block, the sequence of the data block constituted.

Because each data block has corresponding timestamp in First ray, it is possible to determine based on First ray The corresponding timestamp sequence of one sequence.

B, judges whether the timestamp sequence meets: timestamp is ascending order arrangement, and phase in the timestamp sequence The time interval of adjacent two timestamps is not more than third threshold value, if it is, determining that the corresponding audio-video of the target video is same Walking inspection result is qualification, if it is not, then determining that the corresponding audio-visual synchronization inspection result of the target video is unqualified.

Specifically, step b may comprise steps of b1 to b3:

Step b1 determines the first threshold based on the time interval of the timestamp of the adjacent two data blocks of the first audio data Value, and second threshold is determined based on the time interval of the timestamp of the adjacent two data blocks of the first video data.

Specifically, in available first audio data, the time interval of the timestamp of every two adjacent data blocks, determine The rule for the time interval that most time interval is met filters out the time interval for being unsatisfactory for the rule, and will be remaining more A time interval averaged, obtains first threshold, certainly can also be directly to all time interval averageds, can also To take median etc. in multiple time intervals, this is all reasonable, here, not limiting the determination process of first threshold.

The determination process of second threshold and the determination process of first threshold are similar, and details are not described herein.

It should be noted that first threshold and the determination process of second threshold can also be completed before step b, for example, After the completion of audio inspection and video inspection, audio-visual synchronization inspection is completed before starting, this is all reasonable.

Step b2 determines that the smaller in the first threshold and the second threshold is third threshold value.

Step b3, judges whether the timestamp sequence meets: timestamp is ascending order arrangement, and the timestamp sequence In the time interval of two neighboring timestamp be not more than the third threshold value, if it is, determining that the timestamp sequence meets Synchronous condition, if it is not, then determining that the timestamp sequence is unsatisfactory for synchronous condition.

It should be noted that the timestamp sequence must simultaneously meet two conditions:

(1) timestamp is ascending order arrangement；

(2) the time interval of two neighboring timestamp is not more than the third threshold value in the timestamp sequence.

If only meeting a condition, the timestamp sequence cannot be considered as and meet synchronous condition.

Step b3, if the timestamp sequence meets synchronous condition, it is determined that the corresponding audio-video of the target video Verification of synchronization result is qualification, if the timestamp sequence is unsatisfactory for synchronous condition, it is determined that the target video is corresponding Audio-visual synchronization inspection result is unqualified.

It will be appreciated by persons skilled in the art that illustrating audio number if the timestamp sequence meets synchronous condition According to the relationship of block and the play time of video data block, meet the audio data block and video counts that audio/video coding process implies According to the corresponding relationship of block, that is to say, that the timestamp sequence meets synchronous condition, then audio-visual synchronization.
