• Pipe ffmpeg output as mjpeg on multicast port ?

  17 janvier 2020, par xor31four

  I am trying to open a h.264 encoded stream from an IP camera, re-encode and stream it to a multicast address on my local subnet.

  Found a post that seems to describe what I’d like to achieve but I am running into several issues.

  I am using this command :

  ffmpeg -re -i rtsp://192.168.0.11/stream1.sdp mpegts udp://239.168.0.1:11000

  and I am receiving this output :

  [h264 @ 000001531da0ad40] SPS unavailable in decode_picture_timing

  Where am I going wrong ? I am quite inexperienced in this field but determined to learn more.

  Thank you in advance for any pointers on how to go about this..

• ffmpeg pipe blocks while capturing

  26 juin 2013, par Marco Vasapollo

  I have this code :

  public InputStream getInputStream() throws Exception {
  
      try {
  
          process = Runtime.getRuntime().exec("ffmpeg -f dshow -i video=\"" + query + "\":audio=\"" + microPhoneName + "\" -r 25 -vcodec mpeg4 -acodec mp3 -f avi -");
  
          } 
  
          catch (Exception e) {
  
          }
  
      return process.getInputStream();
  
  }

  When i use the inputStream.read(b) command, it works only for a little bit of times (180 to 400 times, depending from formats and codecs I use) then the inputStream lock on read and the application doesn't go anymore.

  What's the problem ? Memory saturation (ffmpeg process memory is at least 14mb) ?
  Is there a way to unlock this situation (clean memory, use a file as a bridge to prevent locks) ?

  Of course I need a little bit of "realtime", and not "post-process".
  I'm not constrained to use ffmpeg, I can change it if necessary.
