How to enable hardware acceleration? #20

Closed Xan-Kun closed 2 years ago

Xan-Kun commented 2 years ago

First of all: Thanks for the fork! This isn't really an issue and more of a question. I try to enable d3d11va hardware acceleration using the command

--postprocessor-args='-hwaccel d3d11va'

in the last line of the config-file. But I only get an error

### ERROR: Postprocessing: Error opening output files: Invalid argument

I am aware this might not be the right place to ask and I would love to ask again or repost this in a better place if anyone knows the answer.

From the docs:

--postprocessor-args NAME:ARGS        ... Specify the postprocessor/executable name
                                      and the arguments separated by a colon ":" ...

I don't see the NAME in your --postprocessor-args, only ARGS.

If it still doesn't work after specifying the NAME, please provide verbose logs (-v argument), so that we can see how FFmpeg is actually invoked.

Is hwacel meant to be an input arg, or an output arg? If input, you'll have to do --ppa "ffmpeg_i:-hwaxel ..."

Holemoley & OMG! It worked at first try and mergin of 30min video is down from ~2Minutes to like a few seconds.

Thank you so much! Really appreciate the time you took to anwer. Please have a wonderful day.

Edit: Sorry, from all the excitement I forgot to paste the actual working line.

In yt-dlp.config file (but should also work from command line) --ppa "ffmpeg_i:-hwaccel auto" btw, depending on system is the same as --ppa "ffmpeg_i:-hwaccel d3d11va"
