[Libav-user] Per-frame metadata

[Jan Brehmer]

Hi everyone.

I am trying to set per-frame metadata with


  av_dict_set(&(frame_->metadata), "timestamp", "1337", 0);


right before ?avcodec_encode_video2?. I have tried it on all functioning combinations of [webm, mpegts, flv, mp4] x [VP8, VP9, H.264] whithout success.
(I used VLC and grep --text "timestamp" to check.)

Is there a way of doing this?

Best regards,
Jan
