  • ffmpeg v4l2 taking 100% cpu usage

    16 novembre 2022, par didentifier

    I am on Fedora 37, version is irrelevant as I had same issue on Fedora 36.

    


    I am using the following command to send video from my usb video card to v4l2loopback and the CPU usage goes to 100% and I can't do much more on my computer (i5-8600k, nvidia 2060 rtx, 16GB ram).

    


    ffmpeg -nostdin -threads 1 -f video4linux2 -video_size 1920x1080 -input_format mjpeg -i /dev/video1 -f v4l2 -preset fast -c:v copy /dev/video0

    


    previously the command was like that and the rest of the arguments was added to see if it makes any difference, it seems it doesn't change much

    


    ffmpeg -f video4linux2 -video_size 1920x1080 -input_format mjpeg -i /dev/video1 -f v4l2 -c copy /dev/video0

    


    To be honest I don't know much about ffmpeg or video in general, I was using the same command a few months ago on the same hardware with almost 0 impact to my performance, I could play games and watch videos at the same time while now I get 15 FPS in my games while I am using ffmpeg. Did anything change in ffmpeg ? Any improvements to my ffmpeg command ? Shouldn't ffmpeg not encode anything if I am using pixelformat and frame rate supported by my usb video card and if that is true shouldn't be super light ?

    


  • How to record audio with ffmpeg on ubuntu 22.04 with python ?

    22 juillet 2024, par Dinh Chu

    I encountered the problem of recording output audio on Ubuntu with Python.
I want to record the output sound from the browser.
I used USB Headphone as the output device, then record sounded with FFMPEG.

    


    pactl list short sources

    


    0. alsa_output.usb-0c76_USB_PnP_Audio_Device-00.analog-stereo.monitor  module-alsa-card.c      s16le 2ch 48000Hz       SUSPENDED
1. alsa_input.usb-0c76_USB_PnP_Audio_Device-00.mono-fallback  module-alsa-card.c      s16le 1ch 48000Hz       SUSPENDED 
2. alsa_output.pci-0000_00_1f.3.iec958-stereo.monitor     module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED


    


    When I run command on Ubuntu, It recorded audio successfully.

    


    ffmpeg -f pulse -i alsa_output.usb-0c76_USB_PnP_Audio_Device-00.analog-stereo.monitor -t 10 output.wav


    


    However, when I executed the command in the project Python, the error reported :

    


    alsa_output.usb-0c76_USB_PnP_Audio_Device-00.analog-stereo.monitor: Operation not permitted


    


    or if using orther ouput :

    


    alsa_output.pci-0000_00_1f.3.iec958-stereo.monitor: Operation not permitted
