Maximum Access Unit Size for rate control (in bits) (from 0 to INT_MAX) (default 0) Quantization Parameter for B-Frame (from -1 to 51) (default -1) Quantization Parameter for P-Frame (from -1 to 51) (default -1) Quantization Parameter for I-Frame (from -1 to 51) (default -1) Rate Control Based Frame Skip (default false)

Rate Control Method (from -1 to 3) (default -1)Ĭqp E.V. Quality Preference (from 0 to 2) (default speed) Profile Level (from 0 to 62) (default auto)

Encoder Usage (from 0 to 3) (default transcoding) Here are the options for the h264_amf (H.264) and hevc_amf (H.265 or HEVC) encoders which you would use with an AMD graphics card, taken from ffmpeg -h full: h264_amf AVOptions: So my question is: How does the ffmpeg command look like to use AMD Hardware for h264 encoding?Ĭurrent versions of ffmpeg now support hardware encoding for the major GPU vendors.

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. If i am using CPU encoding everything works smooth. The Video starts lacking and skipping frames. 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 other one is a AMD R5 M330 that will be used for graphic intense applications like gaming.Ĭurrently, 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 Eas圜amera':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 one is most likly used for non-demanding Applications like office etc. The first GPU is a Intel HD 5500 Graphics Unit as Part of the CPU. Now it gets a bit tricky here with my Laptop. 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. I am currently trying to record a Video on my Lenovo Laptop with its Built-In Webcam using FFmpeg on Windows 10.
