I've been getting failures about 30% of the time. I finally captured one
of them with -v playback:

Comment(by Deyan <mythtv@…>):

I also get this on a T61 Laptop with Fedora 11 and a Quadro NVS 140M card
(512 MB shared RAM allocated to the graphics card - the machine itself has
4GB and at least half of it is always free or used by the disk cache).

With the VDPAU backport of 0.21 playback was excellent but with .22 RC1 it
fails with similar errors (I'll get a verbose log and attach it to the
ticket as well).

Same thing for me. It never happens the first time I playback after I have
freshly opened the frontend. But on subsequent playbacks, it's hit or
miss.

Comment:

The logs show quite clearly that the driver believes it has insufficient
video memory for all of the video buffers. I'm surprised, however, given
these are 512Mb cards.

So:-

- please try with the latest stable driver (190.42). There have been
improvements in memory management, though I don't think they will help
here.

- can you confirm that this is still happening with 0.22/0.22-fixes. There
was a fix for a sizeable video memory leak in the OpenGL painter but I
can't honestly remember whether that went into the RC1.

- check there are no other programs running that might be using video
memory and hence competing with MythTV for those resources.

- confirm which theme and UI painter you are using.

- confirm whether the composite extension is enabled and in use (i.e.
compiz etc)

To help alleviate the problem, try:-

- reducing the video buffer size in the playback profile by adding
vdpaubuffersize=XX to the filters entry. I don't expect this to help much
however, given how early the failure is happening. Likewise ensure you
disable all other vdpau options (deinterlacing, noise reduction etc) - for
testing purposes at least.

- change to a lightweight theme and use the qt painter (and disable
composite if it is enabled).

- close any/all other programs that may be using large amounts of video
memory.

- disable OpenGL vsync if you are using it.

thanks

Mark

Comment(by Deyan):

I upgraded to the final 0.22 release and using vdpaubuffersize=6
everything plays fine although on 1080i programs I sometimes lose the OSD
(this also used to happen with the 0.21 VDPAU backport and I don't think
it's a big issue for my laptop FE). With 0.21 I could use the Advanced x1
deinterlacer even for HD programs and now I could only use Bob x2 but
again for such a small screen and casual viewing it's perfectly OK.

Comment(by leemind):

I suffered from this problem as well. First time it would play, but then
subsequent attempts was very hit-or-miss. I'd loose the OSD 90% of the
time. This is on an Acer Revo 3600 with the ION chipset.

However, seeing this thread and another on the net I managed to dig around
in the BIOS and changed the allocated video memory from 128Mb (default) to
256Mb (Max allowed by the BIOS) and the difference has been huge. I only
did this last night, but it didn't fail on me once, so an immediate
improvement.

[PS. Great work guys.]

Comment(by superm1@…):

Mark:

I'm iteratively trying each of the bullet points you recommended, so a
final response will take a bit of time. Here's where i'm at so far:

* I am using OpenGL painter with the Mythbuntu theme
* I don't have compiz in use, but the composite extension is enabled
* I've got 2 gigs of ram, and the only other large thing that should be
competing for the ram is apache for mythweb.
* I have updated to the latest -fixes, 22783 at this time. Still occurs.
* I have updated to the 190.42 driver and I'll keep testing with it.

If the 190.42 driver doesn't help things, i'll try to continue your other
suggestions. My understanding is that the Mythbuntu theme is considered
pretty lightweight, so not sure I can do much better there.

Okay looks like I was able to reproduce again on 190.42.

I also checked and OpenGL Vsync was already disabled. Carrying on through
the bucket list.

Comment(by Doug Goldstein <cardoe@…>):

#7611 is probably a dup of this issue. I've got an ASRock ION 330 that
experiences this exact same issue that is running Mythbuntu 9.10 with
auto-builds of 0.22 fixes. I'm using the VDPAU Normal playback profile.
Odd thing is my friend has the exact same machine with the exact same
software, the only difference is that he's changed his playback profile to
a custom one and it works every time for him.

I'll work through the list of items to try myself.

* I'm using 185.18.36.
* Using 0.22 fixes. I know it happened with the mythbuntu 0.22 deb based
off of r22840.
* Just using plain Mythbuntu that starts right into Mythfrontend and
that's it.
* Using Mythbuntu (widescreen) theme, using OpenGL painter.
* Composite extension is explicitly disabled in xorg.conf
* I've tried with and without OpenGL Vsync.
* I've got 2GB of RAM with 256mb allocated to the video chipset.
* I never leave Myth at the Watch Recordings screen, I always exit out to
the main menu.

The problem only occurs when the frontend is left idle or running for a
while. For example, I use it at night after work and everything I try to
playback works just fine. It won't be used during dinner and then after
dinner it still works. But then the next day if I come home during lunch
and try it, it doesn't work. That's roughly 12 hours after I stopped
watching TV the night before.

I would suspect its a memory leak overtime or the CPU stepping down its
clock and then not able to provide data fast enough.

Well the issue happened again this morning after being idle all night. I
reset it this morning and I've just come back to the machine and it
happened again.

As you can see from that log snippet, 4 hours and 25 minutes of being idle

Comment(by markk):

(In [22890]) Add an explicit warning around video memory shortages when
using VDPAU
in release-0-22-fixes as well as advice on how to rectify the problem.
Refs #7493 and #7570.

I'm not applying to trunk as this whole section of code will change for
0.23.

Comment:

I'm closing this as I can't see what else can be done for the 0-22-fixes
branch. Going forward there may be an opportunity to flush the OpenGL
painter cache, and hence free up some video memory prior to displaying
video, but that is an invasive option that will not be backported.

Comment(by Doug Goldstein <cardoe@…>):

markk,

What can be done would be to detect the error and exit back to the Watch
Recording screen with an "out of memory" message on the screen instead of
the current behavior which is to completely deadlock the frontend
requiring a kill from a terminal window.
