  • Hardware accelerated video processing tools for Linux

    1er mai 2016, par geoffreak

    I am looking into options for command line video processing tools for Linux, but I am having a hard time find any. FFmpeg doesn’t support hardware acceleration as far as I can tell and I don’t see many alternatives.

    The machines that will be running the software are running CentOS and each has a NVIDIA Tesla card available. While the CentOS can be swapped with something else (not Windows), it would be great to have something that supports CUDA or OpenCL.

    I don’t have any strict requirements for what actually needs to be processed, but I just want to see what options are available for this hardware.

  • avcodec/h264 : remove redundant and bogus get_format call

    avcodec/h264 : remove redundant and bogus get_format call

    The AVCodecContext.get_format callback is not only used for pixel format
    
negotiation with the API user, but also for hwaccel init. For the
    
latter, it’s required that some codec parameters, in particular the
    
codec profile, are set when the callback is invoked.
    

    This patch removes a get_format invocation where this is not guaranteed.
    
The codec parameters, including the profile, are really set further
    
below. (The same code path that sets the profile also calls get_format
    
properly too.)
    

    This just happened to work by coincidence in most cases. For example, if
    
the API user just copied or reused the AVStream’s AVCodecContext when
    
decoding, the profile would be set properly. But in some cases it
    
fails., such as with the sample WolfensteinTwitch.mp4 on the samples
    
server.
    

    Remove the redundant get_format call. Apparently it serves no purpose
    
anymore, although it is possible that this was different at the time it
    
was added in commit ffd77f94a26be22b8ead3178ceec3ed39e68abc5.
    

    This fixes hwaccel usage for API users which do not set the profile
    
when setting up the AVCodecContext (which is allowed).

  • Live streaming to YouTube over HLS with FFMPEG [closed]

    19 septembre 2022, par Ash Raj

    When I stream my FaceTime camera to YouTube over HLS, my video freezes every couple seconds. Which settings do I have wrong, or am missing ?

    


    ffmpeg \
-f avfoundation \

-video_size 1920x1080 \
-pixel_format yuyv422 \
-probesize 10M \

-method POST \
-f hls \

    I'm troubleshooting this with my FaceTime camera right now, but I plan on using a capture card with a 4K studio camera after I get this working
