  • Can you make fluent-ffmpeg use a copy of ffmpeg running inside a Docker container ?

    1er septembre 2020, par Bdyce

    I have some nodejs code in a folder on a host machine that has an npm module that requires an environment variable to be set in order to utilize an executable called FFmpeg. I have a containerized FFmpeg along with its dependencies for development purposes and am now wondering how I am able to specify the path to the FFmpeg executable from the host machine in order for this npm module to function correctly.

    


    I have the idea to use a docker volume that exposes the executable from the container onto the host and then to set the environment variable using that path but I'm not sure if this will work.

    


    Some notes from the module's docs.

    


    


    If the FFMPEG_PATH environment variable is set, fluent-ffmpeg will use it as the full path to the ffmpeg executable. Otherwise, it will attempt to call ffmpeg directly (so it should be in your PATH). You must also have ffprobe installed (it comes with ffmpeg in most distributions). Similarly, fluent-ffmpeg will use the FFPROBE_PATH environment variable if it is set, otherwise it will attempt to call it in the PATH.

    


    


  • AForge.NET ffmpeg codec open error on Windows

    5 octobre 2017, par MTsuchi

    I often get the below ffmpeg codec open error while I run the WPF application that I create using AForge.NET. I need to save videos from a few USB cameras simultaneously through multiple threads. I get the error after I record videos several times. If anyone had solved a similar issue and gave me some ideas to solve, I would appreciate it.

    Stack Trace

    AForge.Video.VideoException - Cannot open video codec.

  • FMS FLV (Speex) to mp3/mp4/acc/wav

    26 novembre 2013, par tkcsam

    I'm trying to decode an FLV's audio to a playable format. I attempted to use this SO post : FMS FLV to mp3.. as an example, but my FLV is encoded in Speex.

    I have compiled ffmpeg with —enable-libspeex on a Fedora 15 machine.

    I believe this can be done with ffmpeg but I'm having a hard time figuring out how to do it.

    Any thoughts ? Thanks
