  • ffmpeg : convert a video by using another video's settings

    11 janvier 2015, par orcaman

    I have an mp4 file containing an H.264 video. This video has particular settings that I am not sure about, but I want to reproduce them on other videos that I encode (those other videos are already H.264 encoded, but they have different properties - bitrate, size, etc.)

    I know that ffprobe can be used to extract some information from the original video, and I guess that using this information I could try to reproduce the conversion settings required for use with other videos.

    Question is : do I have to do this manually, in the sense that I need to map the output of ffprobe to ffmpeg flags ? Is there a better way to do this, to make sure I don’t miss anything ?

    [11:00:43] <jamrial> michaelni : what do you think of 8f5de34c8f ? does it apply to us ?
    
[11:01:50] <jamrial> our code started to deviate with your commit bca59d7745e, followed by the merge commit aa40df483b2
    
[11:33:51] <michaelni> jamrial, the fade commits are from 2013, but i think our fixes where complete and the problematic slice_h FFALIGN is also removed
