  • 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. 
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.

    



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

    



    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


    



    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.

    



    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 ?

    


  • 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 ?
