MP4 播放卡顿和加载速度慢的问题请看

Generally, the default ijk kernel, if there is a lag or asynchronous, it is usually because the soft decoding process is not enough. You can try the frame loss processing in the problem collection, or switch to the exoplayer kernel. At the same time, some MP4 files are unreasonable. The difference between the audio and video PTSs at the approximate location is relatively large. This leads to constant requests for 206 partial content to seek and read the stream content. I once encountered a video of more than 100M that consumed several G of mobile traffic when playing. It took me a long time to find out that the media file had defects. Local playback will not have this problem.
