• raspberry pi, ffmpeg, libmp3lame stream to icecast2 fails with : av_interleaved_write_frame() : Connection reset by peer

  9 avril 2016, par seekwhencer

  finally, i want to merge or mix audio channels from two streams into one new audio stream. but at first i want to relay or reencode an existing stream from an icecast2 server - and send it back to the icecast as new mountpoint. this stream comes from mpd on the same raspberry pi 2. and it works fine.

  i’ve got lame and ffmpeg on this way :

  cd /usr/src
  
  git clone https://github.com/rbrito/lame
  
  cd lame
  
  sudo ./configure
  
  sudo make
  
  sudo make install

  then ffmpeg

  cd /usr/src
  
  sudo rm -R ffmpeg
  
  git clone git://source.ffmpeg.org/ffmpeg.git
  
  cd ffmpeg
  
  sudo ./configure --arch=armel --target-os=linux --enable-gpl --enable-libmp3lame --enable-nonfree
  
  sudo make
  
  sudo make install

  A simple test fails with :

  **av_interleaved_write_frame(): Connection reset by peer
  
  Error writing trailer of icecast://admin:hackme@127.0.0.1:8000/listen: Connection reset by peersize=       5kB time=00:00:00.28 bitrate= 144.7kbits/s speed=1.73x**

  (with strange spaces)

  The reencoding ffmpeg script :

  ffmpeg \
  
   -i http://127.0.0.1:8000/live \
  
   -c:a libmp3lame -b:a 128k \
  
   -legacy_icecast 1 \
  
   -content_type audio/mpeg \
  
   -ice_name "hack radio" \
  
   -f mp3 icecast://admin:hackme@127.0.0.1:8000/listen \
  
   -y \
  
   -stats \
  
   -report

  I tried legacy_icecast 1 or 0.

  The ffmpeg report :

  The icecast works fine with mpd. And icecast creates a new mountpoint when feeded.

  For some reason the connection to the icecast drops. Ideas ?

• ffmpeg av_interleaved_write_frame() : Broken pipe under windows

  7 avril 2016, par Allen

  I am using ffmpeg to convert original media file to rawvideo yuv format, ouputed the yuv to pipe, then my command tool receive the raw yuv as input, do some processing.

  e.g :

  D:\huang_xuezhong\build_win32_VDNAGen>ffmpeg -i test.mkv -c:v rawvideo -s 320x240 -f rawvideo - | my_tool -o output

  every time, when run the command, ffmpeg will dump this av_interleaved_write_frame(): Broken pipe error msg :

  Output #0, rawvideo, to 'pipe:':

  Conversion failed!

  in my souce code : it take stdin as the input file, every time, it read a frame size content from it, if the content read is less than a frame size, then continue read, until a frame is fetched, then it use the frame content to generate something.

  int do_work (int jpg_width, int jpg_height)

  frame_size = jpg_width * jpg_height * 3 / 2;
  
  va_log (vfp_log, "a frame size:%d\n", frame_size);

  if (!yuv_buf) {

  my question :

  when piping used ,does ffmpeg write content to pipe buffer as soon as it has content, or it will buffer some size content, then flushes them to pipe ?Maybe some internal logic that I misunderstood,any one could help explain or fix my code ?

  PS : this command run ok under linux.
