• FFmpeg with multiple output streams

  22 novembre 2018, par William Blake

  I am using ffmpeg to combine an rtsp stream with an audio stream from a usb mic. I would like to stream the combined audio and and video to an RTMP stream and just the audio to an icecast stream simultaneously. I have them working separately but am having difficulty finding the magic combination using the -f tee parameter. It seems like that would be the best way. This was the reference I was trying to use : https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs

  Here are the separate commands :

  ffmpeg -rtsp_transport tcp -use_wallclock_as_timestamps 1 -thread_queue_size 1024  \
  
  -i "rtsp://RTSP-SERVER-ADDRESS" \
  
  -f alsa -thread_queue_size 1024 -ac 1 -itsoffset 00:00:01.2 -i hw:1,0 \
  
  -vcodec copy -acodec mp3 -ar 44100 -ab 32k -map 0:v -map 1:a -bufsize 12000k \
  
  -f flv 'RTMP-SERVER-ADDRESS'
  
  
  
  ffmpeg -ac 1 -f alsa -i hw:1,0 -acodec mp3 -ab 32k -ac 1 -content_type audio/mpeg -f mp3 icecast://ICECAST-ADDRESS

  However my attempts to combine them have been futile. Any thoughts ?

  I was trying to follow this tutorial that uses DCM4CHE software to create DICOM from JSON objects :

  However, I got into an issue related to step 3 :

  


  I just followed the tutorial and used the same video. Could it be related with using new DCM4CHE version ?
