AVS2 (AVS2-P2) is the Chinese national standard that preceded AVS3. The signal is a raw elementary stream, with no container: libdavs2_1 splits it on the picture and sequence start codes and emits one raw frame per picture, which libx264_1 and isobmff_1 then turn into the MP4 the <video> element plays. All 50 frames come out, and match a natively built davs2 to ~58 dB PSNR.
