I'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 Output:

I then tried copying one of the command examples in the linked ddagrab wiki page, but also no luck.
ffmpeg -f lavfi -i ddagrab -c:v h264_qsv output.mkvOutput:

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?
