I played with some avcodec parameters by directly using ffmpeg cmd tool. ./ffmpeg -hwaccel d3d11va -hwaccel_device 1 -report -f lavfi -i nullsrc -c h264 -f null - With this command, ffmpeg reported: [AVHWDeviceContext @ 0000021e06c6a180] Using device 8086:591b (Intel(R) HD Graphics 630) Changing -h...

Thank you for your answer.

How much work would it required to add new parameter to libVLC and pass it on to avcodec?
I assume it'd not cause regression to add one but I'm quite unfamiliar with libVLC codebase so I'm not sure if it's worth trying.

Hello, I am trying to play multiple H264 encoded streams simultaneously. I have two AMD FirePro GPUs (OS: Windows 7) which I'd like to use for decoding those streams. I've managed to utilize the first GPU for decoding by passing parameter --avcodec-hw=dxva2 . The problem is that by default, avcodec ...
