• Ffmpeg rebroadcast icecast stream and disconnect on silence

  4 janvier 2023, par CallumCat

  Currently, I'm using a combination of the Windows version of butt and VLC Media Player in order to rebroadcast an icecast stream from a remote icecast server to my local icecast server, whilst disconnecting whenever a certain duration of silence is detected.

  


  I would really prefer if there would be an easier way to do this on linux from the command line, so that it can run 24/7 without me having to constantly fix the VLC stream player every so often.

  


  I need a way for if silence is detected on the stream, it disconnects the relay and will reconnect whenever audio is detected again.

  


  As I've said before, I've been successfully using butt and VLC Media Player on Windows to do this, however would prefer a linux alternative.

  


• FFmpeg (HLS) - Split segments by size rather than time (or limit segment size)

  28 février 2019, par iMostLiked

  So I have a ffmpeg command with the following parameters (in NodeJS, but it doesn’t matter) :

  '-start_number 0',
  
  '-hls_key_info_file ' + HLSKEY_PATH,
  
  '-hls_time 5',
  
  '-hls_playlist_type vod',
  
  '-hls_segment_filename seg-%d.ts'

  Everything’s working fine, but there’s a problem with the size of each segment.
  Why can’t ffmpeg create segments by size rather than time ? In this case -hls_time 5. I was hoping doing something like -hls_size 4096 but there’s no option for that, at least from what I know. Or can I at least set a limit ? Like : "Don’t create segments bigger than 4MB, split them again if necessary."

  I know I could encode the file again and then there wouldn’t be segments which vary in size that much, but this is no option and alternative for me.

  Thanks in advance !

• Merge remote-tracking branch ’rdp/dshow_crossbar’

  23 janvier 2015, par Michael Niedermayer

  Merge remote-tracking branch ’rdp/dshow_crossbar’
  * rdp/dshow_crossbar :
  
    dshow : fix docu escapes
  
    dshow : some devices only list themselves under "Video sources" but actually have both video and audio output pins, so make the audio pins accessible by video source name.
  
    dshow : add options for allowing filter popup configuration dialogs to be presented to the user
  
    dshow : introduce support for crossbar [multiple input selectable] devices
  
    dshow : drop initial audio packets with weird timestamps
  
    dshow : use non deprecated api
  
    dshow : miscellaneous tweaks
  
    dshow : allow selecting devices by an alternative name (workaround for devices with symbols in them), allow specifying capture pins by name and alternative (unique) name
