Nouveau - Jun 2012 - [Bug 51579] New: Xv video support is black on NVidia NVa8 Chipset in latest git

https://bugs.freedesktop.org/show_bug.cgi?id=51579

             Bug #: 51579
           Summary: Xv video support is black on NVidia NVa8 Chipset in
                    latest git
    Classification: Unclassified
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: boris at boris.ca
         QAContact: xorg-team at lists.x.org


I have one of the Zotac all-in-one PC's with the Nvidia ION chipset
(NOUVEAU(0): Chipset: "NVIDIA NVa8") and it seems the latest
xf86-nouveau
driver from GIT is broken when trying to use Xv support for video playback. All
it shows is a black screen. The GPU is not locked up as I can hear the audio
during playback but the video is black. The last working version from git was
commit 5ac2ca8c56ec8b055878c8ac4cbc8ca74379abda - "works implement and use
PUSH_DATAu" and then starts failing at commit
b48bcc094beecf521899dd63c8fdbccfd534e5cd - "nv50/exa: perform texcoord
transformations in vertex program" all the way up to the latest git version
from today. The Xorg.0.log seems to be fine. (snippet)

I did some additional tests with mplayer.

mplayer -vo X11 Test.avi = Works
mplayer -vo Xv Test.avi = Black screen
mplayer -vo gl Test.avi = Works
mplayer -vo gl2 Test.avi = Works

I wonder if it's something specific to nva+ chipsets?

same issue. BTW: This is the AIO PC. (

Works fine on my NVA8 using mplayer. Have you tried a different video? Have you
tried a different player?

Yes, same here:

(rev a2)

I have not tested git revisions, but I also get black video on Xvideo playback.
I first noticed with mythtv, but Xvideo also does not work under mplayer.
However, X11, gl, and gl2 work.

I'm not sure if this is of interest:

I verified that with a build of 5ac2ca8c5 (the parent commit of b48bcc09),
xvideo under mplayer does work. Before I had been using 1.0.1.

Unfortunately for me, xvideo under mythtv still produces a black screen. But I
can verify Boris's original report.

And now I can verify that under b48bcc094b, mplayer with -vo xv gives a black
screen, just like 1.0.1.

I downloaded the latest nouveau from git today and it's still black when
using
Xv. I tried with both mplayer AND now vdr and it still black.

It may be useful to compare the xorg-server version as well as the output of

I was using 1.12, so I built 1.13 and indeed the screen is black. I don't
see
how b48bcc could work with 1.12 and not 1.13 though at first glance.

I have spent the last day debugging and checking what was different between the
two revisions and working against the latest xf86-video-nouveau from git and I
have come with a fix (atleast for me) that now shows Xv again. Mplayer and vdr
using Xv now works.

NACK to this patch in its current form.  We need to find out what exactly is
wrong rather than revert to a passthrough shader.

That said, I *still* can't reproduce the issue on *either* of my NVA8 boards
using the following config:

kernel-3.6.0-0.rc1.git6.1.fc18.x86_64
libdrm-2.4.38-2.fc18.x86_64
xorg-x11-drv-nouveau-1.0.1-4.fc18.x86_64
xorg-x11-server-Xorg-1.12.99.904-1.20120808.fc18.x86_64

Tested using GNOME 3 in normal and fallback mode to test composited vs
non-composited.  All good in both cases.

Can you give more information on your environment so I can try and see the
issue here?

If it's not effecting your NVa8 board, maybe its something specific to the
GT218 [ION] nvidia cards or NVaX chipsets? (NVIDIA Corporation GT218 [ION] (rev
a2)). I just rebuilt the following packages from git today (11/17/2012) to see
if it helped and nothing.

linux kernel 3.7.0rc6
libdrm 2.4.40+ (mesa/drm git)
nouveau/xf86-video-nouveau (1.0.4+ git)
xorg (X.Org X Server 1.13.99)

Is their any other info or details I can do to provide you any extra
information?

I'm using version 1.13 of the gentoo xorg-driver package with nouveau
selected,
and I get exactly the same issue. My card is an ASUS 210. Of course, the nvidia
driver works perfectly. Mplayer shows videos in gl, gl2, and x11, but not xv.

Oddly, the problem did not occur when I first installed the card. I put it in
and booted with the nvidia driver, then changed over to the nouveau driver,
then removed nvidia and continued to test, restarting at each step. Mplayer
worked normally at every stage. Then I shut down to put the box back together,
restarted, and... black video.

Next I reinstalled the nvidia driver, loaded it, and saw normal video. The
nouveau still has the same issue.

Please confirm that this is still an issue with the latest kernel (3.11+) and

It's working fine now running linux kernel 3.14.0-rc4+ (from git), latest
nouveau from git and the latest Mesa 10.1rc3. You can close this bug.

I have exaclty the same problem but on different hardware, its a 9400 GT.

06:00.0 VGA compatible controller: NVIDIA Corporation C79 [GeForce 9400] (rev
b1)

I am using kernel 3.14.1, mesa3d 10.1.1 and xorg-xf86-video-nouveau 1.0.10.

mplayer -vo xv = black
mplayer -vo vdpau = black
mplayer -vo gl = ok
mplayer -vo gl2 = ok

Please help! I'm so close to ditching nvidia's closed source driver for
nouveau.

Actually I'm reasonably sure that this is the same hardware as the original
bug
reporter. Can you attach dmesg and xorg logs?

Odd. VDPAU is a lot more like GL than like Xv.

Finally I could get Xv working, but vdpau is still not.

I had a problem with /dev/dri/* permissions, after fixing that, and changing
mplayer's configuration as documented in various forums, its still not
working.
 But now I don't get a black screen, mplayer just stops after a few frames.

Please attach them here. Feel free to scrub out the lines that you don't
want
to make public. I mainly want to see the kernel cmdline + nouveau/drm log lines
+ most of the Xorg log would be nice.

Does OpenGL work? What does glxinfo say? How about vdpauinfo? I'm not aware
of
any hangs. (I assume you have the fw installed... if you didn't it
wouldn't
hang, just put up lots of errors.) Have you tried multiple videos? mplayer's
output would be good too.

Sorry, I was not very descriptive, I didn't mean that mplayer hangs, it just
stopped after less than a second (no video, just a few audio frames).  So I
guess it was decoding, but not able to output any video.

After spending some time, and thanks to your valuable pointers, it is more or
less working.

I didn't even have the firmware before, I found out when running vdpauinfo.

Right now it works in about 10% of the cases.  For some files it doesn't
work
at all.  The ones that work break with some video filters (for example, -vf
pp=de).  It this documented somewhere? I would like a list of what works and
what doesn't.

Unfortunately, mplayer doesn't fall back to a different video-output when
vdpau
doesn't work (eg: mplayer -vo vdpau,xv ...).  Some people use a wrapper
script
to achieve this, I guess I'll do the same.
But at the same time, I didn't notice a big difference in CPU usage between
Xv
and vdpau, so maybe I'll just stick with Xv.

Overall I'm very happy with nouveau now.  In fact, I just built it into my
kernel to get KMS, and ditched nvidia's driver for good, after so many years
of
being stuck with it.

Not so happy with mplayer issues though, I guess that is why there are so many
forks.

Thanks a lot for your invaluable help!

vf + vdpau generally don't work. If you're looking for deinterlacing,
the
latest mesa (10.2-rc1) should have support for it (via DEINTERLACE_TEMPORAL),
you can turn it on with "mplayer -vo vdpau:deint=3" IIRC. I do recall
the black
bars being weird when you do that though, but that is an mplayer-only artifact,
apparently.

Note that VDPAU is Video Decoding + Presentation. So if you're seeing high
cpu
usage, it's probably just doing the presentation and not the decoding (for
which you don't need firmware, btw). Make sure you're using the
appropriate
codec (e.g. -vc ffh264vdpau). See
http://nouveau.freedesktop.org/wiki/VideoAcceleration/#usingvdpau

I'm sorry to say this, but the bug is still there, it comes at goes at
random
between reboots.

Now I am running:
kernel 3.15.0
xorg-xf86-video-nouveau 1.0.11

And mplayer -vo xv was working fine a minute ago.  Then I rebooted the computer
and now the video plays (can hear audio), but a black screen again.

I tested again several times after restarting X, and still get a black window.
Unfortunately I can't test rmmod nouveau, because I built it in the kernel.

I see this in my Xorg log:

bash$ egrep 'WW|EE' /var/log/Xorg.0.log.old
