  • How do I use piping with ffmpeg ?

    25 janvier 2016, par DiglettPotato

    My goal is to use wget to download an flv file, and pipe the output to ffmpeg to convert it to an MP3. This way the user can download the MP3 without waiting for the FLV to download to my server first. I’ve been playing around with it, and it seems that ffmpeg can only do piping on raw video. So I was working with something like this :

    wget -O - 'videoinput.flv' | ffmpeg -y -i - -vcodec rawvideo -f yuv4mpegpipe - |  ffmpeg -y -i - -ab 128k audiooutput.mp3

    Anybody have experience with this type of on-the-fly ffmpeg encoding process ?

  • How to resolve "ffmpeg was killed with signal SIGSEGV" in docker container

    25 juin 2024, par Gmanicus

    I have a Node.js application deployed to a docker container with fluent-ffmpeg, @ffmpeg-installer/ffmpeg, and @ffprobe-installer/ffmprobe.

    


    Here is the fluent-ffmpeg init script :

    


    import ffmpeg = require('fluent-ffmpeg');
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const ffprobePath = require('@ffprobe-installer/ffprobe').path;

ffmpeg.setFfmpegPath(ffmpegPath);
ffmpeg.setFfprobePath(ffprobePath);

export default ffmpeg;


    


    This gets used to take a snapshot of a video and save that image to file :

    


    ffmpeg('ism manifest here')
        .inputOption(`-ss timestamp`)
        .outputOptions([
            '-vframes 1',
            '-vf crop=640:230:320:490,eq=saturation=0:contrast=1000,negate'
        ])
        .output('test.png')
        .run();


    


    Whenever any configuration of ffmpeg command is run, it nearly instantaneously fails with :

    


    Error: ffmpeg was killed with signal SIGSEGV&#xA;     at ChildProcess.<anonymous> (/app/node_modules/fluent-ffmpeg/lib/processor.js:180:22)&#xA;     at ChildProcess.emit (node:events:517:28)&#xA;     at Process.ChildProcess._handle.onexit (node:internal/child_process:292:12)&#xA;</anonymous>

    &#xA;

    I have attempted to raise the memory and CPU usage limits of the server in the docker-compose file :

    &#xA;

    ...&#xA;    deploy:&#xA;      resources:&#xA;        limits:&#xA;          cpus: &#x27;0.75&#x27;&#xA;          memory: 2G&#xA;        reservations:&#xA;          cpus: &#x27;0.50&#x27;&#xA;          memory: 1G&#xA;

    &#xA;

    But nothing has worked. Running this on my local machine works just fine. Help ?

    &#xA;

    UPDATE :

    &#xA;

    I just attempted running a small dockerized ffmpeg test script on its own in its own brand new container. Same issue. So, it doesn't seem to have anything to do with my server's configuration.

  • Partial video processing using .webm

    27 octobre 2015, par Ned Rockson

    I’m currently working on taking a bunch of segments of videos that I have chopped up into 1 second chunks. What I’d like to do is to be able to, from these chunks, reconstruct a video from a given offset. When I use ffmpeg to do this, the output is garbled at best and at worst just a black frame. It appears that there are some boundary issues with .webm that I can’t find easily documented so wondering if there’s a simple way to achieve this goal.

    Currently the only solution I have is downloading all 1 second chunks, concatenating them, and then using ffmpeg to create the clip.
