• ffmpeg : Check read_ffserver_streams() return value

  27 novembre 2017, par Pan Bian

  ffmpeg : Check read_ffserver_streams() return value
  The function avformat_alloc_context() will return a NULL pointer on
  
  failure. However, in function read_ffserver_streams(), its return value
  
  is not validated and the subsequent dereference may result in a bad
  
  memory access bug. Check its return value against NULL and avoid
  
  potential NULL dereference.

• typeError when using ffmpeg with buffer in NodeJS ["argument must be of type string or an instance of Buffer"]

  16 mars 2021, par coolps811

  I am trying to covert buffer data into the correct mp4 video format. However I am getting an error : "UnhandledPromiseRejectionWarning : TypeError [ERR_INVALID_ARG_TYPE] : The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of FfmpegCommand". How can I fix this ?

  


  router.post("/download", (req, res, next) => {
  axios({
    method: "get",
    url: req.body.url,
    responseType: "arraybuffer",
  }).then(function (response) {
    const data = new Uint8Array(Buffer.from(response.data));

    const proc = new ffmpeg(data)
      .videoCodec("libx264")
      .outputOptions(["-movflags isml+frag_keyframe"])
      .toFormat("mp4")
      //.seekInput(offset) this is a problem with piping
      .on("error", function (err, stdout, stderr) {
        console.log("an error happened: " + err.message);
        console.log("ffmpeg stdout: " + stdout);
        console.log("ffmpeg stderr: " + stderr);
      })
      .on("end", function () {
        console.log("Processing finished !");
      })
      .on("progress", function (progress) {
        console.log("Processing: " + progress.percent + "% done");
      });

    fs.writeFile("Assets/test.mp4", proc, callback);
  });

  const callback = (err) => {
    if (err) throw err;
    console.log("It's saved!");
  };
});


  


• avformat/framehash : also print channel layout as a string

  29 septembre 2016, par James Almer

  avformat/framehash : also print channel layout as a string
  This should be more useful for users since numerical values for channel
  
  layout can be confusing and unintuitive.
