  • ffmpeg v4l2(UVC camera) stream h264 video to local device

    10 août 2020, par Lawrence song

    I have a UVC camera which supports h264 protocol. we can see the h264 listed below when we list all formats supported.

    I am running the ffmpeg cmd to record UVC camera video to local device.

    


    ffmpeg -f v4l2 -input_format h264 -framerate 30 -video_size 1280*720 -i /dev/video1 -c copy /sdcard/Movies/output.mkv


    


    The video size is way bigger than running the command below :

    


    ffmpeg -f v4l2 -input_format mjpeg -framerate 30 -video_size 1280*720 -i /dev/video1 -c:v libx264 -vf format=yuv420p /sdcard/Movies/output.mp4


    


    I assume the camera already supports h264 protocol. Thus I don't need to re-encode to 264 formats. However, the video size does not look like an H264 encoded video.

  • kmsgrab : Use GetFB2 if available

    kmsgrab : Use GetFB2 if available

    The most useful feature here is the ability to automatically extract the
    
framebuffer format and modifiers.  It also makes support for multi-plane
    
framebuffers possible, though none are added to the format table in this
    
patch.
    

    This requires libdrm 2.4.101 (from April 2020) to build, so it includes a
    
configure check to allow compatibility with existing distributions.  Even
    
with libdrm support, it still won't do anything at runtime if you are
    
running Linux < 5.7 (before June 2020).
