• Trying to stream H264 with Janus Gateway to web browser

  15 mars 2021, par sibrown

  I have installed Janus-Gateway using the very comprehensive install instructions on an Ubuntu 18.04LTS machine.
I have configured the streaming config file (janus.plugin.streaming.jcfg) with :

  



  gstreamer-sample: {
  type = "rtp"
  id = 1
  description = "H.264 live stream coming from gstreamer"
  audio = false
  video = true
  videoport = 5004
  videopt = 96
  videortpmap = "H264/90000"
  videofmtp = "profile-level-id=42e01f;packetization-mode=1"
}


  



  (I didn't change the name because that required least changes to other files.)

  



  Having then started the server, I then take a pre-encoded stream and send that to the server with ffmpeg :

  



  ffmpeg -i udp://127.0.0.1:9034 -c:v copy -an -f rtp rtp://127.0.0.1:5004?pkt_size=1300


  



  Opening up the demo webpage the server comes with, I go to streaming demos, and choose the "gstreamer" demo and click start. The right hand half of the screen produces a spinning circle, but tells me that it is receiving data at the appropriate rate for the stream I'm sending. So if it's receiving the stream, why isn't it playing it ?

  



  Cheers,
Simon

  


• ffmpeg player in discord.py (python) automatically leave

  25 octobre 2018, par Rastasplif

  I have created a discord bot that on certain messages either sends back a message or plays a sound (like a soundboard)

  The crucial line of code is :

           soundboard_player = voice_client.create_ffmpeg_player("doh.mp3")
  
           soundboard_player.start()
  
           await client.send_message(message.channel, "Playing DOH...")

  This works absolutely fine but i kept trying to add the line
  after=voice_client.disconnect()
  I put this inside the ("doh.mp3", * I PUT IT HERE *) brackets.
  I wanted the bot to leave after it was done.

  When I run the code with the ’after’ statement included, the bot joins and I get the error message :

  TypeError: disconnect() takes 1 positional argument but 2 were given

  I know you can use soundboard_player.is_done() to check the status of the bot but I couldn’t figure out a way to check the status without trapping the code in a loop

  By trapping the code in the loop I cant execute a STOP command to stop it playing the song (soundbite) half way through.

  Any help with the after=voice_client.disconnect() command for the ffmpeg player
  or a creative way to periodically check the status without getting trapped in the loop ?

• avformat/asfcrypt : Fix wrong array length in function declaration

  avformat/asfcrypt : Fix wrong array length in function declaration
  multiswap_step() and multiswap_inv_step() both only require
  
  six keys ; in all current callers, these keys are part of
  
  an array of twelve keys, yet in some of these callers the keys
  
  given to these functions point to the second half of these
  
  twelve keys, so that only six keys are available to these functions.
  
  This led to -Wstringop-overread warnings when compiling with GCC 12.1.
  
  Fix these by adapting the declaration of these functions.
