Hardware Acceleration DVXA

Postby asoksevil » 08 Jan 2015 23:27

I am just curious about what "type" of DVXA VLC 2.2 RC2 uses since AFAIK Movist: https://itunes.apple.com/gb/app/movist/ ... 8075?mt=12 CPU usage is way lower. On an average 1080p MKV H.264 video I manage around 20-30% CPU usage compare to VLC's 40-50%.

Using VLC I can't even play this video (H.265 MKV): http://trailers.divx.com/hevc/TearsOfSt ... _7subs.mkv

Lot of stuttering, grey pixelated screens with 140%f of CPU usage while Movist just manages it fine and even under 100% of CPU usage.

All these tests have been carried out on my 2010 MacBook Air 1.86 GHz 4 GB RAM.

Hi there,

I'm sorry for the misunderstanding. I meant DVXA as a shorten version of "hardware accelerated." My bad, I shouldn't have said that considering that it's a technology used on Windows. According to VLC 2.1.5, there's hardware acceleration decoding:

"Add hardware decoding for OS X using VDADecoder.
Add hardware decoding for Android using MediaCodec.
Add hardware decoding for GNU/Linux using VDPAU."

I wanted to say that it's just very inefficient compared to the one used by Movist or there's something that I'm not doing correctly.

Thanks for the reply!

You need to activate the OSX hardware acceleration by hand. So you should check your input/codec preferences before you start doing any comparisons (VDA needs to be selected in the drop down list).

Also note that it is normal that VLC might be consuming a little bit more CPU, so we can still activate our video filters to the final image (which is not hardware accelerated so far).
And h265 cannot be hardware accelerated at the moment on osx (neither with Movist nor with VLC).

Hey there,

They are both activated on VLC and Movist.
