Summary of the bug:
I use the demuxing_decoding example to decode an H264 stream that contains
different sizes of sub-GOP (dynamic B-Frames). The first five sub-GOPs
have 3 B-Frames. The sixth sub-GOP has 7 B-Frames and is not decoded
correctly.
How to reproduce:
{{{
./demuxing_decoding CNBC_3B_7B_in.264 CNBC_3B_7B_out.yuv
CNBC_3B_7B_out.pcm
ffmpeg version : git-master
built on CentOS 6.6
}}}
Result :
{{{
Coded frame 24 is missing. It should be between coded frames 17 and 23.
}}}
