A video playback method and device

Abstract

The invention relates to a video playing method and apparatus. The video playing method comprises the following steps: S1, determining the difference between the audio decoding time stamp and the video decoding time stamp of a currently played device is greater than a preset threshold; and S2, when the difference between the audio decoding time stamp and the video decoding time stamp of the currently played device is greater than the preset threshold, performing Gauss smooth filtering on video frames after decoding. The video playing method further comprises; S3, when the difference between the audio decoding time stamp and the video decoding time stamp of the currently played device is not greater than the preset threshold, performing deblocking filtering processing on the video frames after the decoding. According to the invention, videos can be played smoothly on a play device with quite low performance, and at the same time, the blocking effect is not caused due to closure of deblocking filtering.

Description

technical field [0001] The present invention relates to video decoding technology, and more specifically, to a video playing method and device. Background technique [0002] In the video decoding process, whether it is H.264 encoding format, RV40 encoding format or some other common encoding formats, deblocking filter (deblock) will be used to post-process the decoded video frames, which can remove the block effect (due to the encoding process) has a better effect. However, the deblocking filtering process is a part with relatively high complexity and the most time-consuming decoding in the whole decoding process. For some handheld devices such as mobile terminals with relatively low performance or without hardware accelerated decoding, the deblocking filter algorithm may sometimes cause the decoding to fail, resulting in audio and video out of synchronization and video playback screen is not smooth.

Problems solved by technology

However, deblocking filtering is the most complex and time-consuming part of the entire decoding process.

For some handheld devices such as mobile terminals with relatively low performance or without hardware accelerated decoding, the decoding algorithm sometimes does not work when using the deblocking filter algorithm, resulting in out-of-sync audio and video and unsmooth video playback.
