I'm running 10.12.6 on an i5 4430 with a GTX 950 connected to a 4K screen.
I'd like to record my screen in 4K@60Hz with H.264 encoding. I haven't been able to get this to work.
I have two separate problems:
1) Unable to output 60Hz from GPU
2) Unable to capture screen using hardware support
I'm hoping to fix the first problem by purchasing a DP -> HDMI adapter (https://tinyurl.com/yd9vjnxg).
I'm unsure how to fix the second problem. I've been using ffmpeg with something like:
ffmpeg -f avfoundation -s 3840x2160 -r 60 -i 0:0 -c:v libx264 recording.mkv
But this maxes my CPU and records at about 10fps.
When ffmpeg runs, it says:
IOVARendererID property not found
AVDCreateGPUAccelerator: Error loading GPU renderer
So it looks like it's trying to use hardware acceleration but failing. Is there any way to make this work?
I tried compiling ffmpeg from source with CUDA support but couldn't make that work.
I also looked into Intel QuickSync to utilise my HD4600 iGPU, but couldn't figure that out.
Any suggestions would be greatly appreciated. Thanks
