    From what I understood is it isn't supposed to care about the video sizes when doing it this way?

  • How to add a 5.1 .flac audio track to a .ts file with already 3 audio tracks ?

    16 mai 2018, par Pablo

    I want to add a 5.1 .flac audio track to a .ts file that already has three audio tracks. I tried with tsMuxer and ffmpeg with unsuccessful results. In tsMuxeR the .flac track is not recognized and in ffmpeg everything seems to work fine until the very last moment when I check the file and the .flac audio track is not included in the "output.ts". The .flac track is about 3GB and its lenght is around two and a half hours.

    Thank you so much.

  • FFMPEG with node , using child_process , suppressing un-necessary stderr

    16 mai 2018, par drexdelta

    I am trying to resize the video using (FFMPEG + node + child_process). and my code looks something like this , You can read comments and understand it. it's self-explanatory for people who are familiar with node and ffmpeg. when I run this code, I keep getting error in newThread.stderr.on() function . which is not expected behaviour. After running this process I am getting expected video translation, which is expected behaviour.

    const spawn = require('child_process').spawn;

// resize and compress video promise  = prom2
const resizeVideoWith_FFMPEG_Promise = (sourceFile , sinkFile)=>{
    return new Promise ( (resolve , reject)=>{

        // actual command for ffmpeg is something like this , "ffmpeg -i oldVideo -vf scale=-2:480 newVideo"
        // New thread
        const newThread = spawn('ffmpeg' , ['-i','vid1.mp4','-vf','scale=-2:480','vid2.mp4']);

        // on close signal
        newThread.on('close',(data)=>{
            console.log(' thread closed for video ' , sourceFile);
            return resolve();
        });
        // on stderr signals
        newThread.stderr.on('data',(data)=>{
            console.log(' got error in the thread of video ' , sourceFile);
            fullError = data.toString();
            console.log(fullError);
            // return resolve();
            // return reject();
        });
        newThread.stdout.on('data',(data)=>{
            // just ignore all stadanrd outputs
        });
    });
}

resizeVideoWith_FFMPEG_Promise('vid1.mp4' , 'vid2.mp4' ).then((res)=>{
    console.log(res);
});

    For the sake of simplicity I am resolving the promise everytime, even if I get stderr. And at end of running this code I get output something like this ,

     got error in the thread of video  vid1.mp4

    Now, my problem is if I always keep resolving errors, then I will never be able to catch when the video ACTUALLY FAILED TO RESCALE. so, how can I ignore these type of un-necessary stderr and catch only useful errors ?

    Pls someone help.

    I have been through lot of related links like this, but none of these actually solve my problem(even if they did, I couldn't figure out)

    Error while using h264_cuvid decoder with ffmpeg

    Using module "child_process" without Webpack

    Suppressing STDOUT with node child_process

    Small hint will be very helpful. Thank you .

    BTW , SO moderators , My actual title was like

    stderr problem while using FFMPEG with node via child_process module

    But it didn't allow me to use such title. so, I am using some dummy title.

  • -to value smaller than -ss error while clipping videos with ffmpeg

    16 mai 2018, par dusa

    I am trying to clip videos using frame information, I first convert the frame to time since ffmpeg uses this notion to clip videos.

    The problem is for shorter videos, it gives the error:

    -to; value smaller than -ss; aborting.

    But in reality, this is false. For example, I get an error even with these values:

    0:0:47.4 -to 0:0:47.21  (format -> hh:mm:ss.frame)

    Can anyone tell me how I can fix this?

    The video frame rate is 25 fps and the command structure I use is:

     os.system('ffmpeg -i ' + inputvideo + '.mp4' + ' -qscale:v 2 -vf scale=427:240 ' + ' -ss '+ str(fhours) + ':' + str(fminutes) + ':' + str(fseconds) + '.' + str(fframes) + ' -to ' + str(lhours) + ':' + str(lminutes) + ':' + str(lseconds) + '.' + str(lframes) + ' ' + outputvideo + '.avi')
