I am using ffmpeg to play vp9 videos and I encounter a situation where a certain video stops few frames before the end.
Doc for avcodec_decode_video2 function says that for codecs which have the CODEC_CAP_DELAY capability we need to feed avcodec_decode_video2 with null packets in order to receive all frames.
vp9 codec does not have this capability set, but nonetheless I try to send null packet and codec gets me all frames.
So the questions are:
1. Am I doing it right?
2. Should vp9 have CODEC_CAP_DELAY capability set?

You should ask libav-user: the mailing list for questions involving FFmpeg library usage.
Get an answer more quickly by providing your actual ffmpeg command and the complete console output. Use the code button to format your command and output or your question will be ignored.
