I use ffprobe to get video packet information, including pts/dts:
/usr/local/bin/ffprobe -show_packets -select_streams v hanma.ts


And video key packet information is shown as follows:


[PACKET]

I found 1st video packet output by ffmpeg is not video key packet by comparing pts/dts

But according to avformat_seek_file()'s description:
http://ffmpeg.org/doxygen/3.4/group__lavf__decoding.html#ga3b40fc8d2fda6992ae6ea2567d71ba30
1st video packet should be key packet after calling avformat_seek_file().


But for hanma.ts, it's not the case.




The test clip can be downloaded from:
https://pan.baidu.com/s/1bqxMDHX


Is it a bug in ffmpeg ts demuxer?




Thanks!

Andrew
