Description

Basically I set up a video conference tool. Sometimes the receiving part of the streams throws a series of errors as shown below:

[flv @ 0x7fce98b6d400] Packet mismatch -1057119111 7279 2435819 [flv @ 0x7fce98b6d400] Packet mismatch -228249567 1901323 4337142 [flv @ 0x7fce98b6d400] Packet mismatch -236187797 78347 4415489 [flv @ 0x7fce98b6d400] Packet mismatch -1133241869 2064651 6480140

Does anyone have any idea what could be the issue? Video codec used: H264, format FLV. Audio codec used: AAC

Contributor guide

Research direction
Investigate the 'Packet mismatch' error in FLV stream decoding. Focus on FFmpeg's FLV demuxer and the handling of H264 and AAC packets. Check for timestamp discontinuities or packet ordering issues.
