• youtube_dl, ffmpeg, discord.py is not playing songs even w/o streaming

  27 août 2021, par BlueFire02

  I have tried many times to make a basic queue system, I tested the play command to see if it worked back then and it did, unfortunately during this construction I have been having a lot of problems just playing the song. I did try to implement a queueing system but all that comes out is this specific error :

  


  [tls @ 0x7f8244705240] IO Error: -9806 [https @ 0x7f824480b000] Will reconnect at 835584 in 0 second(s), error=Input/output error.


  


  Additional Info : I also installed ffmpeg onto my mac, I only put the 1 file called ffmpeg in my path if that helps but I am pretty sure it has to do something with youtube_dl.

  


  Code : (Make sure to put your guild_id in the guild_id spot, another thing is when you invite the bot make sure in the 2auth section click 'bot' and 'application.commands')

  Final Note : I did try to download and play the song but in the end it gave me the following error :

  


  Options reconnect not found.


  


• raw h.264 bitstream decoding

  16 septembre 2015, par srjohnhuang

  I can get raw h.264 frames from a camera. (it does NOT contain any network headers, for example rtsp, http).
  They are h.264 raw data.
  And I push these data to a queue frame by frame.
  I googled many ffmpeg example which uses avformat_open_input() with either local file path or network path.
  And I can see the video while I save the frames to a file and using avformat_open_input().

  My problem is that I want to decode the frames realtime, not after it is saved as a file.
  Does anyone have any idea on this ?

  Thanks !

• running multiple tasks (ffmpeg) at the same time in a django app

  23 novembre 2020, par Soufiane

  at the title says it, I made a django app that cuts and merge files with ffmpeg
while testing (me being the only user), it looks fine, but later when using the app from different browsers running tasks at the same time, looks like it's a queue of tasks and other users will wait for their turn,
what I'm thinking about is, is there a possibility to run multiple tasks simultaneously at the same time, like (screens on linux) under django framework ?
thanks a lot
