  • ffmpeg frame rate issue

    3 juillet 2013, par user2529661

    I have been having frame rate issues with ffmpeg. I'm trying to make a mkv file with a raw H.264 input.

    I have to declare a frame rate or it will default to 25 fps, but the text becomes out of sync when I try to set a frame rate with the -r option :

    ffmpeg -r 29.42 -i 2.h264 -i 2.ass -map 0 -map 1 -c copy 2.mkv

    I know the time duration of the H.264 file when I get the frame count using :

    ffprobe -i 2.h264 -show_streams -count_frames

    I can calculate the frame rate and make the mkv file and the text is pretty well synced. This is slow ; it takes about 1 min to process 10 mins of video. My files will be up to 1 hour long and this all has to be done in the back ground from my .net app.

    • Is there a faster way to get the framerate ?
    • Is using ffprobe the best option ?
    • Can I force a duration on the mkv file ?

  • Revision 00d54aa331 : First pass clean up. One of a series of changes to clean up two pass allocation

    9 mai 2014, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_firstpass.c



    First pass clean up.

    One of a series of changes to clean up two pass
    allocation as precursor to support for multiple arf
    or boosted frames per GF/ARF group.

    This change pulls out the calculation of the total bits
    allocated to a GF/ARF group into a function, to aid
    readability and reduce the line count for define_gf_group().

    This change should have no material impact on output.
