• v4l2loopback device detected by Chrome, not seen by Zoom or Firefox

  14 novembre 2020, par uri sh.

  I am trying to create a loopback device from my webcam to be accessible from both Zoom and a browser. I created three v4l2loopback devices :

  


  sudo modprobe v4l2loopback devices=3 video_nr=10,11,12 card_label="Loopback_1","Loopback_2","Virtual_cam" exclusive_caps=1,1,0


  


  followed by :

  


  ffmpeg -i /dev/video0 -f v4l2 -vcodec rawvideo -pix_fmt yuv420p /dev/video10 -f v4l2 /dev/video11


  


  Both devices are detected by Chrome, yet not seen by either Zoom nor Firefox.
Following advice on other questions on stackoverflow I tried setting the device properties using v4l2loopback-ctl, using v4l2loopback-ctl set-caps "video/x-raw,format=UYVY,width=640,height=480" /dev/video10, and got in response :

  


  


  Setting pipeline to PAUSED ...
ERROR : Pipeline doesn't want to pause.
ERROR : from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0 : Device '/dev/video10' is not a output device.
Additional debug info :
v4l2_calls.c(636) : gst_v4l2_open () : /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0 :
Capabilities : 0x85208000
Setting pipeline to NULL ...
Freeing pipeline ...
output to /dev/video10 failed

  


  


  I also tried using gst-launch-1.0 :

  


  gst-launch-1.0 v4l2src device=/dev/video0 ! v4l2sink device=/dev/video10


  


  which tells me that /dev/video10 is not an output device :

  


  


  Setting pipeline to PAUSED ...
ERROR : Pipeline doesn't want to pause.

  I am running Xubuntu 20.04, kernel version 5.4.0-52-generic, with v4l2loopback-dkms v.0.12.3-1ubuntu0.1, and v4l2loopback-utils.

  


  My goal here is to get a device to be consumed by a desktop Node.js server which will open up a web app using xdg-open (thus the need for both Chrome AND Firefox), which will output a processed videostream that could be consumed by a video chat app, such as Zoom or Jitsi.

  


  Any help will be greatly appreciated.

  


• Why is the ffmpeg process in discordpy terminating without playing anything ?

  18 janvier 2024, par Bummbumm6

  I'm making a discord bot for playing music (ik very unoriginal) and everytime I try to play music, it gives this error :

  


  2023-02-18 12:31:54 INFO     discord.player ffmpeg process 4024 has not terminated. Waiting to terminate...
2023-02-18 12:31:54 INFO     discord.player ffmpeg process 4024 should have terminated with a return code of -9.


  


  It is in the voice chat and didn't play anything. Here's my code if you need it :

  


  print("defining functions")
import discord, pytube, os, threading
from moviepy import editor
from discord.ext.commands import Bot
intents=discord.Intents.default()
intents.message_content = True
intents.voice_states = True
bot = Bot("b!",intents=intents)
check = False
token = "redacted"
@bot.command()
async def play(ctx, arg):
            await ctx.send("Downloading...")
            try:
                yt = pytube.YouTube(arg)
                print("STREAM: "+str(yt.streams.filter(only_audio=True,mime_type="audio/webm",type="audio",abr="160kbps")))
                def download(yt):
                    print("DOWNLOADING STREAM TO AUDIO.WEBM")
                    yt.streams.filter(only_audio=True,mime_type="audio/webm",type="audio",abr="160kbps").order_by("abr").first().download(filename="audio.webm")
                    print("EXPORTING TO MP3")
                    editor.AudioFileClip("audio.webm").write_audiofile("audio.webm"[:-5] + ".mp3")
                    os.remove("audio.webm")
                    print("DONE")
                thread = threading.Thread(target=download, args=(yt,))
                thread.start()
                thread.join()
                try:
                  channel = ctx.author.voice.channel
                  try:
                    vc = await channel.connect()
                  except Exception:
                    ctx.send("already in vc, one sec")
                except Exception:
                    pass
                vc.play(discord.FFmpegPCMAudio(source="audio.mp3", executable="./ffmpeg"))
            except Exception:
              pass
bot.run(token)



  


  It worked on my computer in VS Code, but I wanted to test it on Replit and only there I got the error. I tried :

  


  

  1. Reinstalling discord, pynacl, even pytube and moviepy.

  


  2. Using a local copy of ffmpeg on replit, see line 36.

  


  3. Adding the intents that were described in a different thread.

  


  


  One thing that always happens is the exit code being -9 but the process number changing (ofc). I saw a GitHub Issue about this too which is not showing a fix so how do I fix that ?
