  avcodec/videotoolbox : Fix undefined symbol with minimal configuration
  Please reproduced with the following minimal configure command :
  
  ./configure —enable-shared —disable-all —enable-avcodec —enable-decoder=h264 —enable-hwaccel=h264_videotoolbox
  You'll get below error :

  • [DH] libavcodec/videotoolbox.c

• Sinon stun within ffmpeg error event listener

  22 juin 2022, par Pedro Elias

      const {writeStream, upload} = S3Service.uploadStream({ Bucket: process.env.BUCKET, Key: s3Path});

    ffmpeg(stream)
        .outputOptions('-copyts')
        .audioCodec("libopus")
        .toFormat("matroska")
        .on('error', (err, stdout, stderr) => {
            if (err) {
                console.log(err.message);
                upload.abort();
                return reject("Error FFMPEG");
            }
        })
        .on('start', (p) => console.log(p))
        .on(`end`, () => console.log("end ffmpeg"))
        .pipe(writeStream);

    upload.promise()
        .then(() => resolve("Successful audio converted transfer"))
        .catch((err) => console.error(err));


  


  I have the code above and I'm writing a unit test for it as follow :

  


  let uploadStreamStub = {
    writeStream: sandbox.stub().returnsThis(),
    upload: {
        promise: sandbox.stub(),
        abort: sandbox.stub()
     }
}

sandbox.stub(s3Service, "uploadStream").returns(uploadStreamStub);


  


  I'd like to stub upload.abort() :

  


  let onStub = sandbox.stub(ffmpeg.prototype, "on").returnsThis();
onStub.withArgs("error").yieldsAsync(new Error("test"));
sandbox.assert.calledOnce(uploadStreamStub.upload.abort);


  


  However, the stub is not working :
AssertError : expected stub to be called once but was called 0 times

  


  When I remove the "yieldsAsync" line and try to stub the promise it works :

  


  // onStub.withArgs("error").yieldsAsync(new Error("test"));
sandbox.assert.calledOnce(uploadStreamStub.upload.promise);


  


  So the stub only doesn't work on('error'...

  


  What I'm doing wrong ?

  


  How can I stub and check if abort has been called ?

  


• node js ffmpeg hls stream sound is repeating and overlays to each other

  1er avril 2022, par Marty

  I'm trying to stream video and audio with rtmp and I'm stack with problem that I hear sound which overlays to each other and always repeating. But my target is to not repeating and overlay audio to each other. Parsing hls performs with hls.js

  


  This is my ffmpeg config which creates 4 streaming files which includes in master file index.m3u8
