• Getting content-length of a live-re-encoded video

  9 avril 2021, par Marius

  So, i have a lot of hevc(h265) video on a remote http server, that i want to serve as h264 through ffmpeg and nodejs. I've had a bunch of issues with content-length, or in general just getting skipping, and video duration to work properly.

  


  So the main problem is getting content-length, or any other header to make duration and skipping work properly.

  


  I've tried calculating approx content-length, but it never seems to match properly.

  


  My code so far :

  


  express setup here....
app.get('/', (req, res) => {
    res.contentType('mp4');
    
    ffmpeg(remote_video_url)
        .inputOption([
            "-hwaccel auto",
        ])
        .outputOptions(['-movflags isml+frag_keyframe'])
        .videoCodec('h264_nvenc')
        .toFormat('mp4')
        .on('error', (err,stdout,stderr) => {
            console.log('an error happened: ' + err.message);
            console.log('ffmpeg stdout: ' + stdout);
            console.log('ffmpeg stderr: ' + stderr);
        })
        .on('end', () => {
            console.log('Processing finished !');
        })
        .on('progress', (progress) => {
            console.log('Processing: ' + progress.percent + '% done');
        })
        .pipe(res, {end: true});
})


  


  Any help would be greatly appreciated

  


• Crash while using ffmpeg4android using Galaxy s6 edge device

  21 juillet 2016, par Amira Elsayed Ismail

  I am using ffmpeg4android_lib to compress video in my android application, it is working in almost all testing devices but it does not work in Galaxy s6 edge and Galaxy s7 edge.

  my code as following :

  String inputFile = FileManager.getInstance().getRealPathFromVideoUri(context, video);
  
  Log.i("INPUT FILE PATH", inputFile);
  
  
  
  LoadJNI vk = new LoadJNI();
  
  try {
  
          String workFolder = context.getApplicationContext().getFilesDir().getAbsolutePath();
  
          String outputFile = FileManager.getInstance().getFileFullName(ForSaleConstants.VIDEO_FOLDER,
  
          String.format(ForSaleConstants.VIDEO_NAME_FILE_FORMAT,      ForSaleConstants.VIDEO_NAME_FILE_NAME_PREFIX, System.currentTimeMillis()));
  
  
  
          String complexCommand[] = {
  
              "ffmpeg", "-y"
  
              , "-i", inputFile
  
              , "-strict", "experimental"
  
              , "-s", "320x240"

              , "-b", "2097k"
  
              , outputFile};
  
              vk.run(complexCommand, workFolder, context.getApplicationContext());
  
              Log.i("OUTPUT FILE PATH", outputFile);
  
              return outputFile;
  
      } catch (Throwable e) {
  
          ForSaleServerManager.getInstance().logAndroidError("Couldn't compress video file");
  
          return null;
  
      }
