  • How to convert raw .avi to .yuv through command line (YUV420) ?

    27 février 2016, par Natures Wrath

    I have tried the following command to no avail :

    ffmpeg -i in.avi -vcodec rawvideo -pix_fmt yuv420p out.yuv

    I have a raw avi file (which plays video on vlc). I then take .yuv file. I then tried this command :

    ffmpeg -i in.avi -c:v rawvideo -pix_fmt yuv420p out.yuv

    Still, no luck. I am at a loss as to why my output .yuv file is incorrect. I have a sneaking suspicion that my yuv is not being given the proper headers during this conversion.

    Does anyone know what I can do to get a proper .yuv file from a raw .avi (which I have confirmed is playable on vlc) ?

    Output from second command : (please note that "out.avi" is actually my in.avi from above two commands)

  • Putting two videos next to each other, improving performance

    17 mai 2018, par Zurechtweiser

    I am using this command I put together with quite some effort to put two videos next to each other.

    ffmpeg -y -i i1.mov -i i2.mp4 -filter_complex

    [0:v]scale=1824:1026,pad=width=1920:height=1080:x=0:y=27:color=black,crop=1641:923:170:79,scale=1920:1080[vl] ;

    [1:v]scale=2016:1134,crop=1759:1080:48:27,pad=width=1920:height=1080:x=161:y=0:color=black,crop=1641:923:170:79,scale=1920:1080[vr] ;

    [vl][vr]hstack=shortest=1 -c:v libx264 -crf 23 -preset veryfast output

    It works, but it is not elegant.

    How to shorten it and make it more performant ?

    From what I understood is it isn’t supposed to care about the video sizes when doing it this way ?
