  avcodec/pthread_frame : Fix cleanup during init
  In case an error happened when setting up the child threads,
  
  ff_frame_thread_init() would up until now call ff_frame_thread_free()
  
  to clean up all threads set up so far, including the current, not
  
  properly initialized one.
  
  But a half-allocated context needs special handling which
  
  ff_frame_thread_frame_free() doesn't provide.
  
  Notably, if allocating the AVCodecInternal, the codec's private data
  
  or setting the options fails, the codec's close function will be
  
  called (if there is one) ; it will also be called if the codec's init
  
  function fails, regardless of whether the FF_CODEC_CAP_INIT_CLEANUP
  
  is set. This is not supported by all codecs ; in ticket #9099 it led
  
  to a crash.

• avformat/hls : reduce default max reload to 3

  avformat/hls : reduce default max reload to 3
  The 1000 did result in the appearance of a never ending reload loop
  The RFC mandates that "If the client reloads a Playlist file and finds that it has not
  
  changed, then it MUST wait for a period of one-half the target
  
  duration before retrying." and if it has changed
  
  "the client MUST wait for at least the target duration before attempting to reload the
  
  Playlist file again"
  Trying to reload 3 times seems a better default than 1000 given these
  
  durations

• Using Node.js module fluent-ffmpeg to convert video but my files end up corrupt

  28 juin 2017, par El Guapo

  i am writing a node based media encoding tool and have found a few good node packages that will help me to do this, but the output files are either totally corrupt or it only encodes half the video.

  The main node package i am using is fluent-ffmpeg, and i am trying it with the following code :

  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  var proc = new ffmpeg({ source: 'uploads/robocop-tlr1_h480p.mov', nolog: false})
  
    .withVideoCodec('libx264')
  
    .withVideoBitrate(800)
  
    .withAudioCodec('libvo_aacenc')
  
    .withAudioBitrate('128k')
  
    .withAudioChannels(2)
  
    .toFormat('mp4')
  
    .saveToFile('output/robocop.mp4',
  
      function(retcode, error){
  
          console.log('file has been converted succesfully');
  
  });

  There is not a problem with the source video as i encoded it just fine using FFmpeg normally with the following comand line string (i run it from a batch file) :

  "c:\ffmpeg\bin\ffmpeg.exe" -i %1 -acodec libvo_aacenc -b:a 128k -ac 2 -vcodec libx264 -b:v 800k -f mp4 "../output/robocop2.mp4"

  Any ideas what i am doing wrong here ?
