  • 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.

    &#xA;

    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&#xA;

    &#xA;

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

    &#xA;

    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.

    &#xA;

    Any idea why this could be happening ?

  • 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,&#xA;an english one in aac and a french one in dts.

    &#xA;

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

    &#xA;

    I use

    &#xA;

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

    &#xA;

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

    &#xA;

    (ffmpeg version 2023-12-23-git-f5f414d9c4-full_build-www.gyan.dev under Windows 10)
