No Hardware Acceleration

[2BTSquared 5]

Playing back a ripped DVD. MKV container. H.264. 

 

Is the web client and/or MBT using the LAV filters? They show up in the tray when the video is playing so I'm guessing they do. LAV video has DXVA2 set for hardware acceleration but I'm not seeing hardware acceleration when playing the video with MBT or the web client. 

 

Play the same videos in Mediaportal with LAV filters selected and I have hardware acceleration. 

 

So what gives? Any ideas? What logs - if any - should I post?

web client no, mbt yes. hardware acceleration in mbt is entirely dependent on your lav settings, so it's pretty much left up to you.

As I noted... I have LAV settings set to DXVA2 for hardware acceleration. Hardware acceleration using the same LAV video filter with the same exact settings (no changes made when switching between MBT or MP) works fine in MP. So the question is - why does hardware acceleration using Mediaportal work, but it does not when playing the same video in MBT (using LAV) or the web client?

For mbt I don't know, but I do know that it works for us in testing. The web client is played through the browser and will never use lav. We have no control over how the browser plays it, what it uses, or whether it uses HW or not.

Should I repost this question in the MPT forum?

So the browser won't use hw but can MB server transcode using GPU HW Acell? Or am I talking about something that doesn't make sense...lol I'd like to get faster transcodes with more assistance from the GPU. My AMD a8 3870 CPU portion doesn't do well with transcoding on the fly for more than one movie at a time.

[Luke 42077]

at the moment no, but i think the next server release will perform a little better when transcoding.

[A8HTPC 38]

Thanks. So it is possible to have transcoding work through the GPU?

 

Not knowing to much about transcoding, is there any special features in a CPU to help transcoding? I have only read the more cores the better.

[Koleckai Silvestri 1154]

Transcoding is done through FFMPEG and I understand it supports hardware acceleration via the libavcodec. However such support would also need to be programmed into the server to work properly.

 

For your CPU, The more cores you have the more FFMPEG threads that can be run concurrently and therefore the faster the transcode runs. However results still may vary from device to device.

viewing tv and movie on the web gui limit the server to only two cores due to webm/ffmpeg. so for instance, in my case, i have a pretty robust DUAL 6 core (2.4ghz) w/ 32gb of ram, but when my end user client access mediabrowser via the web interface my "robust" server is now severely underpowered compared to an i3 even. My work around right now is using my i5 4670k htpc to run a concurrent MBS+serverwmc but only direct my web clients to it, and let all APP capable clients still connect to the 12core server.
