  • Is this a problem in my command, the stream, or FFMPEG itself ? [closed]

    10 juin, par Ali Mustafa

    I am trying to download a section from approximately 06:40:00 to 06:44:00 from this stream : https://kick.com/grossgore/videos/8d36c089-ff2b-4167-9c92-bc8a3a9d033b

    


    I found the m3u8 URL : https://stream.kick.com/ivs/v1/196233775518/hDSBAWziz2jA/2025/5/25/12/56/LrW3TwZUg7Xk/media/hls/1080p60/playlist.m3u8

    


    I run the following command :

    


    ffmpeg -ss 06:40:00 -to 06:44:00 -i https://stream.kick.com/ivs/v1/196233775518/hDSBAWziz2jA/2025/5/25/12/56/LrW3TwZUg7Xk/media/hls/1080p60/playlist.m3u8 -c copy out.mp4


    


    The command runs for a while, but for some reason the output file is empty once the program has finished. How do I figure out what the problem is ?

  • FFmpeg RTSP stream to remote MediaMTX server disconnects after a few seconds [closed]

    13 juin, par Rorschy

    I'm new to RTSP and MediaMTX, and I'm trying to live stream my screen using FFmpeg and MediaMTX for a specific use case.

    


    Everything works perfectly when both FFmpeg and MediaMTX run on the same machine.
However, when I move MediaMTX to a remote server, the stream becomes unstable — I can't maintain a connection or view the stream reliably.

    


    Here is the FFmpeg command I'm using from the client machine :

    


    ffmpeg -f gdigrab -framerate 10 -offset_x 0 -offset_y 0 -video_size 1920x1080 -i desktop -f lavfi -i anullsrc -vcodec libx264 -tune zerolatency -g 30 -sc_threshold 0 -preset ultrafast -tune zerolatency -f rtsp rtsp:///live/stream


    


    And here’s the relevant MediaMTX log output on the remote server :

    


    2025/06/12 14:28:44 INF [RTSP] [conn :35798] opened

    My questions :

    


      

    1. What could be causing the RTSP stream to disconnect when streaming to a remote MediaMTX server ?

      2. 


    2. Are there any recommended network settings or MediaMTX configuration tweaks to ensure a stable stream over the internet ?

      3. 


    


    Any help or guidance would be greatly appreciated. Thanks !

    


  • v4l2loopback+ffmpeg input for uvc gadget

    13 mai, par Mosi

    I'm trying to use an MP4 video file as the input for a UVC Gadget setup on my Raspberry Pi 4 Model B, but I'm running into an issue when streaming through V4L2.

    


    Goal :

    


    To emulate a webcam that streams a looping MP4 video file to a Windows 11 host.

    


    My setup :

    


      

    • Hardware : Raspberry Pi 4 Model B

      • 


    • OS : Raspberry Pi OS Lite 64-bit (2025-05-06-raspios-bookworm-arm64-lite)

      • 


    • Kernel : 6.12.25+rpt-rpi-v8

      • 


    • Host System : Windows 11

      • 


    • UVC Gadget version : v0.3.0

      • 


    


    Workflow :

    


    [MP4 Video] → [FFmpeg] → [V4L2 Loopback] → [UVC Gadget] → Windows sees virtual webcam


    


    What works :

    


    The UVC Gadget works perfectly when I use a real webcam as the source (e.g., /dev/video0). Windows detects the virtual webcam and displays a smooth video stream.

    


    The problem :

    


    When I try to use an MP4 video file through FFmpeg and send it to the loopback device (/dev/video3), the UVC Gadget fails with the following error :

    


    


    Command I'm using :

    


    ffmpeg -re -stream_loop -1 -i input.mp4 -vf scale=640:480 \
  -c:v rawvideo -pix_fmt yuyv422 -r 30 -f v4l2 /dev/video3


    


    Then I run :

    


    sudo uvc-gadget -d /dev/video3 uvc.0


    


    Output :

    


    bRequestType 21 bRequest 01 wValue 0200 wIndex 0001 wLength 0022
streaming request (req SET_CUR cs 02)
setting commit control, length = 34
Setting format to 0x56595559 640x480
=== Setting frame rate to 30 fps
Starting video stream.
--> [At this point I open the camera on the Windows host]
/dev/video3: 2 buffers requested.
Failed to export buffer 0.
Failed to export buffers on source: Inappropriate ioctl for device (25)


    


    


    Things I've tried :

    


      

    • Multiple FFmpeg formats, resolutions, and pixel formats

      • 


    • Various ffmpeg buffer and framerate tweaks

      • 


    • Different UVC Gadget versions

      • 


    • GitHub related projects (showcamera, etc.)

      • 


    • Older Raspberry Pi OS versions

      • 


    


    Most guides and GitHub projects I found are outdated (5+ years old), and newer methods seem undocumented or incompatible with current kernel/UVC gadget tools.

    


    


    My question :

    


    How can I stream an MP4 file as a virtual webcam using UVC Gadget without getting ioctl errors ?
    
Is there a proper way to set up FFmpeg and loopback devices so that UVC Gadget can read the stream correctly ?

    


    Any modern working example or tips would be very appreciated. Thanks in advance !
