  • ffmpeg - converting one audio track of a multi-track mp4

    30 décembre 2023, par Shaun.M

    I'm having a few mp4 with two audio tracks,
an english one in aac and a french one in dts.

    


    Now I want to convert only the french dts to eac3 with a single ffmpeg command.

    


    I use

    


    ffmpeg -hide_banner -i input.mp4 ^
             -map_metadata -1 ^
             -map 0:0 -c:v copy ^
             -map 0:1 -c:a copy ^
             -map 0:2 -c:a eac3 -b:a 1536k ^
             -metadata:s:a:0 language=eng ^
             -metadata:s:a:0 title="Stereo" ^
             -metadata:s:a:1 language=fra ^
             -metadata:s:a:1 title="Stereo" ^
output.mp4


    


    This works quite nice, but it converts both audio tracks to eac3, instead of leaving the first one untouched ...
What's wrong in the command ?

  • machine hangs during ffmpeg command execution [closed]

    15 décembre 2023, par Tejas

    I'm running this ffmpeg command that does multiple trims on input video and concats those trims to generate output.

    


    ffmpeg -i https://d8r14y803bnlk.cloudfront.net/usetldr/2736037/u/796/st/5a919413ff884892bbfffcd0671687a9/p/67c1a16438bf4bb78b785557f4cef7ef/OJx1SIKTNbbGHmQfKT4C_render.mp4 -filter_complex "[0:v:0]trim=start=0.0:end=4.289,setpts=PTS-STARTPTS,format=yuva420p[0v];[0:v:0]trim=start=4.84:end=1034.7,setpts=PTS-STARTPTS,format=yuva420p[1v];[0v][1v]concat=n=2:v=1:a=0" -crf 18 -an -preset ultrafast -y /tmp/8TZeqB3Z6h.mp4


    


    This command works fine on my M1 mac but hangs EC2 instances (c5.4xlarge).

    


    I'm using ffmpeg version 6.1-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2000-2023 the FFmpeg developers built with gcc 8 (Debian 8.3.0-6) on EC2.

    


    Any idea why this could be happening ?
