  • libavutil : Add av_clip_intp2

    20 février 2015, par Peter Meerwald
    libavutil : Add av_clip_intp2

    there already is a function, av_clip_uintp2() that clips a signed integer
    
to an unsigned power-of-two range, i.e. 0,2^p-1
    

    this patch adds a function av_clip_intp2() that clips a signed integer
    
to a signed power-of-two range, i.e. -(2^p),(2^p-1)
    

    the new function can be used as a special case for av_clip(), e.g.
    
av_clip(x, -8192, 8191) can be rewritten as av_clip_intp2(x, 13)
    

    there are ARM instructions, usat and ssat resp., which map nicely to these
    
functions (see next patch)

  • Video encoder with low CPU usage on Atom 230

    8 février 2016, par Alexandr Zarubkin

    What are my options for screen capturing on Atom 230 CPU that will result in reasonably low CPU usage ?
    I’m using ffmpeg and would like to leave CPU power to other applications while recording a screencast without lags.
    Maybe there’s hardware support for certain codec ?

  • FFmpeg : Encode x264 with AMD GPU on Windows ?

    20 septembre 2023, par ZeroTek

    I am currently trying to record a Video on my Lenovo Laptop with its Built-In Webcam using FFmpeg on Windows 10. One of my goals is to keep the CPU Usage as low as possible, that's why i want to push the h264 encoding to the GPU. &#xA;Now it gets a bit tricky here with my Laptop. Because it uses two GPUs. The first GPU is a Intel HD 5500 Graphics Unit as Part of the CPU. This one is most likly used for non-demanding Applications like office etc. to save Energy. The other one is a AMD R5 M330 that will be used for graphic intense applications like gaming.

    &#xA;&#xA;

    Currently, i am using the following command to encode the Webcam Stream on the Intel HD GPU :

    &#xA;&#xA;

    ffmpeg -f dshow -vcodec mjpeg -video_size 1280x720 -framerate 30 video="Lenovo EasyCamera":audio="Mikrofon (Realtek High Definition Audio)" -c:v h264_qsv -g 60 -q 28 -look_ahead 0 -preset:v faster -c:a aac -q:a 0.6 -r 30 output.mp4&#xA;

    &#xA;&#xA;

    This does work so far but it seems this GPU does not have enough Power to keep up with the framerate on higher bitrates or with a high amount of i-frames. The Video starts lacking and skipping frames. If i am using CPU encoding everything works smooth.

    &#xA;&#xA;

    Now that my Laptop got that second AMD GPU with a lot more Power it would be a nice Try to encode on that one, but i can't find any information about how to encode on AMD Hardware on Windows 10. So my question is : How does the ffmpeg command look like to use AMD Hardware for h264 encoding ?
