How to Install XBMC PVR Xvba for AMD/Nvidia/Intel GPUs

Hey, it seems I was too slow to start this thread Smile

Nice work so far guys.
You really made me happy specifically about one issue I had and it's deinterlacing LiveTV content. At last I can see sports without having a feeling like someone is stabbing me in the eyes Wink

I would like to report a few things, though:
1. Unlike the builds from Lars' repository I'm having lots of crashes when navigating.
2. Fast forwarding on x16 or above stutters
3. Playing a video with the following specs shows a green solid image (Was playing fine on VAAPI)

Code:

Format : AVC 

Format/Info : Advanced Video Codec 

Format profile : High@L4.0 

Format settings, CABAC : Yes 

Format settings, ReFrames : 3 frames

4. For the following video I'm having a constant macro-blocking making it un-viewable (This also happens on VAAPI too, though)

Code:

Format : AVC 

Format/Info : Advanced Video Codec 

Format profile : High@L5.1 

Format settings, CABAC : Yes 

Format settings, ReFrames : 5 frames

Stream size : 2.62 GiB (92%) 

Writing library : x264 core 59 r851M e11ef38 

Encoding settings : cabac=1 / ref=5 / deblock=1:0:0 / analyse=0x3:0x133 / me=umh / subme=6 / me-prepass=0 / brdo=1 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=1 / cqm=0 / deadzone=21,11 / chroma_qp_offset=0 / threads=3 / nr=0 / decimate=1 / mbaff=0 / fgo=0 / bframes=5 / b_pyramid=1 / b_adapt=1 / b_bias=0 / direct=3 / wpredb=1 / bime=1 / keyint=250 / keyint_min=25 / scenecut=40(pre) / rc=2pass / bitrate=7497 / ratetol=1.0 / rceq='blurCplx^(1-qComp)' / qcomp=1.00 / qpmin=10 / qpmax=51 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / ip_ratio=1.40 / pb_ratio=1.30 / aq=2:1.00

But I see in the OP that 5.1 profile isn't supported yet, so never mind.

For the first video:
Could you provide me a sample of the first file? (5MB?)

Second one: 5.1 as you have seen right.

What crashes are this? Does it just quit to desktop or do you get a freeze? Does this happen with Shared Surfaces on? Do you watch interlaced TV while this happens?

If it does not crash to desktop, eg segfaults. Could attach to the running process with gdb?

We have seen some effects in fglrx we are not really amused about...

howto get a gdb backtrace mini howto

In case of a hanging/locked up xbmc process

install gdb:

Code:

sudo apt-get install gdb pastebinit

with XBMC running:

Code:

sudo gdb --pid $(pidof xbmc.bin)

in the gdb shell/prompt (gdb):

Code:

set pagination off

set logging on xbmc-xvba-crash.log

thread apply all bt

detach

quit

cat xbmc-xvba-crash.log ~/.xbmc/temp/xbmc.log | pastebinit

In case xbmc crashes completely to desktop, or X restarts
you should have a xbmc_crashlog* file in your home dir

Code:

cd ~

ls -ltr xbmc_crashlog*  # not needed, just to check if there are crashlog files

pastebinit $(ls -1tr xbmc_crashlog*  | tail -1)

then let us know the url pastebinit outputs.

For some reason after reboot the video can be watched normally, do you still want a sample?

Regarding the crash, it crashes completely.
I'm not using any desktop, so, all I see is just a black screen and then monit restarts XBMC service.
Tell me what info and how to get it, and I'll deliver.

**fritsch** · 2011-12-17 13:15

Okay, this looks like a segfault. Does this crash happen only with Shared Surfaces enabled?

Edit: Do you watch interlaced content when it crashes?

I haven´t seen a crash, but 1 cpu is always at about 50%. It is never in Idle with xbmc on, although i am not playing a movie.

@Infinitatus,
Set VSync to always on under System->Video settings.
It's the FPS that is going crazy here, but putting a limit on them will decrease your CPU usage on idle.
Moreover, try enabling Dirty Regions to decrease it more

As I mentioned earlier, these crashes I'm talking about are happening when navigating the menus. Not watching content.

But if you mentioned it already, I had crashes watching interlaced content. So, I disabled Shared Surfaces.

We currently have some patches in review, but wsnipex was so kind to make a ppa out of it. I will send you the link by pm, in order not confuse people who read this thread from the back. Try to reenable Shared Surfaces and try it a bit.

In order to get reasonable backtraces you have to run xbmc from gdb. After it is running just use the howto from above.

kobik · 2011-12-17 15:58

hey fritsch,
Thank you and wsnipex for the PPA, I'll try it.
Is this PPA going to be updated regularly? Or is just for the latest patches testings?

About the gdb, please be kind to explain exactly what you want me to do.
Although I'm pretty technical, my background with Linux is 3 months only, so there are many black holes for me here.
I do want to remind that I'm running XBMC as a service using this script http://pastebin.com/fQSJ4xJt

**fritsch** · 2011-12-17 16:03

We use the mailed ppa as a testing ppa. There are put new patches and stuff. Afterwards we try our standard movies and samples if it works correctly. After testing in one or two days in every day use we build packages from it and push them into the standard repo.

The interlacing part i have tested with running interlaced content over night and it was still running when i came back - so i am pretty confident that your interlace problem could be better or even solved.

Unfortunaltey you cannot integrate gdb into this script. Please try the testing packages. If they do not make it better for you. I think about a possibility to get you easily into the debugger.
