RE: Nvenc under MAC with EGPU - Selur - 04.02.2018
Hyrid only uses the videotoolbox api through ffmpeg, which sadly isn't that great.
Sadly I can't be of much assistance with this since:
a. I don't own a mac atm.
b. Apple really restricts any hardware decoding through their videotoolbox api which is why you can't access NVEnc directly like you can on Windows and Linux
What you basically do in Hybrid is:
- load a source in Hybrid ('Base->Open file')
- set 'Base->Processing->Video' to 'FFVideotoolbox'
- go into the 'FFVideotoolbox' and select the Encoder (and do additional configuration)
- set output 'Base->Output file'
- add the settings to the job queue ('Base->Add to queue')
- start the encoding ('Jobs->Queue->Start')
Note that monitoring the GPU won't show much since video decoding and encoding doesn't run through the gpu, but the vpu.

Hello,
I'm using A MacPro late 2013 with a AMD RX 580 under EGPU and Mac OSX 10.13.4.
The AMD card works fine under the OS. But when I use your software, he doesn't use
the EGPU card with the acceleration.....
It is something to do ?
Thank for answer....

No clue why FFVideotoolbox doesn't support your AMD card, it should support any card the VideoToolbox Framework from Apple supports.
Sadly I haven't seen any documentation which hardware is supported.

I try today with a other Egpu box and the same GFX card, the problem is the same.
It's still strange that it does not work because
the AMD RX 580 cards is officialy supported in 10.3.4...

Got a link for this?
Just because Apple adds drivers for a card/chipset does Not mean it's supported in their Videotoolbox framework.

Quote:Accelerate applications that use Metal, OpenGL, and OpenCLSadly that didn't include Videotoolbox.
And I can't find any information regarding egpu and the Videotoolbox framework.

Finally I do not understand too much, what are the compatible configurations?
Obviously my 2017 macbook pro is because the compression works perfectly.
I do not see the point of not including external cards ...

No clue either since I can't find any documentation from apple about what hardware is compatible with videotoolbox, only that it is the 'new' framework which should support hardware encoding and decoding. (https://developer.apple.com/documentation/videotoolbox)
Quote:I do not see the point of not including external cards ...I do not see the point in lots of stuff apple does when it comes to lots of things related to video encoding and container support.
Apple often only supports fractions of standards and they never seem to expand such support.

Is Open Gl & CL fast to encode H265 ?
