• FFMPEG, macOS Catalina : "ffmpeg stderr : /private/tmp/com.apple.launchd.ID/org.macosforge.xquartz:0 : Operation not supported on socket"

  11 février 2021, par Bogdan Slyusarenko

  I'm trying to record selenium test run with FFMPEG, for automation testing of web extensions (selenium+js/ts).
FFMPEG initiated by command :

  


      const { spawn } = require("child_process");
        ffmpeg = spawn("ffmpeg", [
          "-x265-params",
          "-f",
          "xcbgrab", 
          "-video_size",
          "1280x1024", 
          "-i",
          process.env.DISPLAY, // "/private/tmp/com.apple.launchd.ID/org.macosforge.xquartz:0"
          "-loglevel",
          "debug", 
          "-y", 
          "-pix_fmt",
          "yuv420p",
          videoPath, 
        ]);


  


  Return constantly error,related to process.DISPLAY, I'm not sure why it's so :

  


      ffmpeg stderr: /private/tmp/com.apple.launchd.W851FkeNXz/org.macosforge.xquartz:0: Operation not supported on socket

• electron app fluent-ffmpeg " Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height"

  27 juillet 2020, par Martin

  I am trying to run an ffmpeg command in my electron app. I have created the function ffmpegTest() based off instructions for setting up ffmpeg here :

  


  https://alexandercleasby.dev/blog/use-ffmpeg-electron

  


  and the example query for ffmpeg-fluent here :

  


  https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/blob/master/examples/image2video.js

  


  function ffmpegTest(){
    console.log('ffmpeg-test')
    //require the ffmpeg package so we can use ffmpeg using JS
    const ffmpeg = require('fluent-ffmpeg');
    //Get the paths to the packaged versions of the binaries we want to use
    const ffmpegPath = require('ffmpeg-static').replace(
        'app.asar',
        'app.asar.unpacked'
    );
    const ffprobePath = require('ffprobe-static').path.replace(
        'app.asar',
        'app.asar.unpacked'
    );
    //tell the ffmpeg package where it can find the needed binaries.
    ffmpeg.setFfmpegPath(ffmpegPath);
    ffmpeg.setFfprobePath(ffprobePath);
    
    var imgPath = "C:\\Users\\marti\\Documents\\martinradio\\uploads\\israel song festival 1979\\front.jpg"
    var outputPath = "C:\\Users\\marti\\Documents\\martinradio\\uploads\\israel song festival 1979\\output.m4v"

    // make sure you set the correct path to your video file
    var proc = ffmpeg(imgPath)
    // loop for 5 seconds
    .loop(5)
    // using 25 fps
    .fps(25)
    // setup event handlers
    .on('end', function() {
    console.log('file has been converted succesfully');
    })
    .on('error', function(err) {
    console.log('an error happened: ' + err.message);
    })
    // save to file
    .save(outputPath);

    console.log("end of ffmpeg-test")
}


  


  it is trying to convert an image to a video, my filepaths are accurate, but when I run this function, I get this output in console :

  


  ffmpeg-test
index.js:137 end of ffmpeg-test
index.js:132 an error happened: ffmpeg exited with code 1: Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!


  


  After the error prints out, I can see my output.m4v file inside my output folder, but it is 0KB in size and wont open. Is there some way I can specify my bit_rate / rate / width / height in my fluent-ffmpeg command so I can run this simple ffmpeg command ?

  


  thanks
