  • dashenc : Fix writing of timelines that don’t start at t=0

    29 décembre 2014, par Martin Storsjö
    dashenc : Fix writing of timelines that don’t start at t=0

    When writing an explicit time, reset the cur_time variable to this
    
value as well. This avoids writing excessive time attributes for each
    
segment in the timeline, as long as the segments are continuous.

  • Adjust Audio Start Point by 3 Frames

    11 mai 2022, par craigeley

    Because of an issue with my audio recorder, I have audio files that are always 3 frames behind the start of my video files, even though they have identical timecode. Currently, I am overcoming this issue by using -itsoffset, like so :

    &#xA;

    ffmpeg -i video.MP4 -itsoffset 0.12512513 -i audio.WAV -c:a aac -map 0:v:0 -map 1:a:0 new.mp4&#xA;

    &#xA;

    Where 0.12512513 is 3 divided by 23.976. The results of this are satisfactory, but is contingent on all of my footage being shot in 23.976.

    &#xA;

    However, since I spoke to tech support for the device and they assured me it will always be off by exactly three frames, I'm wondering if there is a faster and more universal way to do this, either a) a command like -itsoffset that accepts frames as a starting point, or if the better solution is to just cut off the first three frames of the video, which would also put them in sync. I have tinkered with trim=start_frame=3 but I can't figure out the correct position to place it within the command.

    &#xA;

    Any advice from experienced ffmpeg'ers would be much appreciated !
