  • ffmpeg how to encode first then use it for another output

    10 août 2017, par mahdi gh

    I’m trying to capture screen with gdigrab and combine int with a sound and then send it on my decklink sdi device.

    here is my code to capture :

    ffmpeg -framerate 25 -thread_queue_size 512 -f gdigrab -i title="Play" -f dshow -i audio="CABLE Output (VB-Audio Virtual Cable)" -af aresample=resampler=soxr -ar 48000 -acodec pcm_s16le -ac 2 -c:v libx264 -qp 0 -preset ultrafast "output.avi"

    here is my code for output to ffmpeg :

    ffmpeg -i output.avi -f decklink -pix_fmt uyvy422 "DeckLink SDI (2)"

    this way it works, but when I combine these two arguments to send the output to decklink card on the fly, ffmpeg stops working. here is the combination code :

    ffmpeg -framerate 25 -thread_queue_size 512 -f gdigrab -i title="Play" -f dshow -i audio="CABLE Output (VB-Audio Virtual Cable)" -af aresample=resampler=soxr -ar 48000 -acodec pcm_s16le -ac 2  -f decklink -pix_fmt uyvy422 "DeckLink SDI (2)"

    I have tried so many different combinations but no luck. it works only if i store it on a file then use that file as input. Is there a way to tell ffmpeg to use the result of first command as input of second command ?

    Thanks

    Update :
    Here is log report :

    15 août 2017, par asif

    this is a line from ffmpeg video converter php script ;

    $ffmpeg." -i ".$video_to_convert." -vcodec flv -f flv -r 30 -b ".$quality."-ab 128000 -ar".$audio." -s ".$size." ".$converted_vids.$name.".".$new_format."

    where :

    .$video_to_convert. = input file

    .$converted_vids.$name. = output file

    .$new_format. ; = file extention format

  • Ffmpeg/Fluent-Ffmpeg : Output file #0 does not contain any stream

    16 août 2017, par Code Sherpa

    Use Case

    When a user records an audio file and uploads to firebase storage, run a trigger that crops a clip of that file and saves it to a "preview" directory.

    Problem

    Getting Output file #0 does not contain any stream after static .AAC file is downloaded to temp directory and ffmpeg command is run.

    Environment

    • mac client / firebase storage
    • node v8.1.0
    • ffmpeg v3.2.2
    • fluent-ffmpeg v2.1.2

    Node Code

      var command = new ffmpeg({ source: tempFilePath, timeout: 0 })
    
      .setFfmpegPath(ffmpegPath)
    
      .setFfprobePath(ffprobePath)
    
      .inputOption('-t', '10')
    
      .inputOption('-ss', '10')
    
      .outputOption('-acodec', 'copy')
    
      .on('start', function(commandLine) {
    
            console.log('Spawned Ffmpeg with command: ', commandLine);
    
       })
    
      .on('end', function() {
    
          console.log('Preview file cropping done successfully');
    
       })
    
      .on('error', function(err, stdout, stderr) {
    
          var build = err;
    
          if (!stdout === '') { build = build + '\n' + stdout; }
    
          build = build + '\n' + stderr;
    

    
          console.log(build);
    
       }).save(tempFilePath);

    Ffmpeg Command

    Spawned Ffmpeg with command : ffmpeg -t 10 -ss 10 -i

    Comments & Observations

    • I am able to run the ffmpeg command (provided above) locally and get the results I want.

    • The origin file is AAC. I have verified that it is, indeed, an AAC file and not a different file type masquerading as an AAC.

    • The output file format appears as audio/x-aac in firebase. I would expect it to be the same as the origin file - audio/aac.
