[FFmpeg-user] Trouble playing video encoded using h264_v4l2m2m

Hi all,

I am feeding one frame at a time to h264_v4l2m2m encoder, and getting
encoded packets using avcodec_receive_packet function, and write to
file using av_write_frame. When I run ffprobe on the output file, I
get this error:

st: 0 edit list: 1 Missing key frame while searching for timestamp: 0
[h264 @ 0x1831fb0] no frame!

The exact same application code works with libx264 encoder. What am I
missing here? Help?
