D3D11 hardware screen recording with ffmpeg using Intel H264 QSV hardware encoding
13 mai 2024, par CactusI'm trying to screen record using
ffmpeg
and having it all done via hardware on my Intel integrated graphics.

Specs


For reference, here are my specs :


- 

- Windows 11 Pro Version 10.0.22631 Build 22631
- Model : Dell Inc. OptiPlex 3090
- Processor : 11th Gen Intel(R) Core(TM) i3-1115G4 @ 3.00GHz, 2995 Mhz, 2 Core(s), 4 Logical Processor(s)
- Terminal : Windows Terminal using Windows Powershell










In this wiki, it looked like I could use the "Windows 8+ Desktop Duplication API" to be "directly encoded by a compatible hardware encoder" — so I thought that I could use
h264_qsv
to encode, allowing me to record without much performance overhead costs.

Attempt 1


I've tried copying one of the command examples, but it didn't work :


ffmpeg -init_hw_device d3d11va -filter_complex ddagrab=0

ffmpeg -f lavfi -i ddagrab -c:v h264_qsv output.mkv

My main problem is that I don't know how to use really any of these encoders and the examples I've found above don't work with me. What command should I use to screen record all with hardware acceleration on my Intel system ? I don't care about any presets or other options at the moment.


Is there also a way to record audio ? When I tried to use
-f dshow -i audio="Stereo Mix (Realtek(R) Audio)"
by itself, which I made sure was turned on in Windows' settings and named correctly, it didn't work (is it because I'm using Bluetooth headphones that isn't connected to Realtek's system ?). Should this question be made separately than this one ?
