  • ffmpeg : is there a simple way to edit the video resolution, but keep all audio and subtitles

    21 avril 2022, par Arkeen

    I would like to lower video resolution - usually from .mkv files - but to keep all possible audio tracks (might be only one, might be several) and subtitles (might be none, might be several) from the original one. I also would like to keep as many encoding parameters as I can from the original video file (especially those I do not understand).

    


    I am still new to ffmpeg : at first the idea seemed simple, but after many attempts, it seems it is more complex than that. Do I have to use the -filter_complex option ? It seems to be an overkill (or overcomplex) for what I thought to be an easy conversion, but I might be wrong.

    


    I tried to combine -vf scale=-1:720 with -c copy -map 0, which gave me an error that I now understand, but I am stuck with the next step.

    


    Any lead on to achieve that ? Could it be done with ffmpeg only or would I need a script ?

    


  • FFMPEG Recode all audio streams while keeping originals

    15 mars 2021, par Olirav

    I am trying to add a additional set of audio tracks into some video files, as part of a automated process. I would like to keep all the original audio tracks and have a second re-coded copy.

    



    What I have been using is :

    



    ffmpeg -i file
-map 0:v -codec:v copy
-map 0:a -codec:a copy
-map 0:a:0 -codec:a:0 aac -strict experimental ...(Bitrate, filters etc all with :a:0)
-map 0:s -codec:s copy
output file


    



    However I can't work out how to change this to handle input files that have multiple audio tracks as it will only convert the first.

    



    If I change the :a:0 to :a on the codec line it produces the extra copy I need but overrides the copy codec for the original copy.

    



    Any ideas anyone ?
