• determine video file's (typical ?) keyframe frequency

  2 avril 2012, par pdkl95

  Is there any way to use common tools (ffmpeg ? mplayer/mencoder ? mkvmerge ? etc) to find how often keyframes appear in a given video file ? and thereby finding the minimum seek size ? It seems like such an obvious statistic that there "must" be some common technique...

  [if it helps, assume MKV container, H.264 video - I'd love to find a more general solution, but maybe that's not possible/practical ?]

• Supporting dependency of P frame on I frame only

  16 février 2018, par MSD Paul

  I have a doubt on x264 encoding.

  If I have IP_1P_2P_3 IPPP some kind of this GOP from the x264 encoded output. Then in general, P_3 will be dependent on I, P_1 and P_2, P_2 will be dependent on I and P_1 (a cumulative encoding).

  Can anyone please give me any ideas how can I support direct encoding so that all P_1, P_2, P_3 will be only dependent on the I frame ?
