Can't get it to work on Firefox 96/NVIDIA 470.94 #29

Closed guihkx closed 2 years ago

For some reason, Firefox 96 doesn't seem to be enabling VA-API, despite me configuring everything as per the README file.

Firefox log:

Gbm/DMABUF is disabled by default below 495.44.

guihkx commented 2 years ago

Ah, dang it. Any way to force-enable it on Firefox? Or the 470 driver series don't even support it? If that's the case, I'm afraid NVIDIA won't ever implement the gbm stuff for the 470 driver branch. And because my GPU is from 2012, the 470 driver branch will be the last one supporting my GPU. :S

Darkspirit commented 2 years ago

If I unterstand correctly, 470 only supports Dmabuf, but not Gbm. It might work with widget.dmabuf.force-enabled=true, I don't know.

SupervisedThinking commented 2 years ago

Well your problem is simple: GTX 660

You need at least a Maxwell based GPU so your card is more or less EOS... 🤔

guihkx commented 2 years ago

It might work with widget.dmabuf.force-enabled=true, I don't know.

Yeah, I don't think so... image

You need at least a Maxwell based GPU

Why though? Is it because this only works with the 495 driver series or there are some other reasons as well? I think we should add this information to the README.

elFarto commented 2 years ago

If I unterstand correctly, 470 only supports Dmabuf, but not Gbm.

Do you know why exactly GBM is needed? Technically only DMA-BUF is required for this library to work, and having it work with the older driver would enable a lot of people with older cards to use it.

SupervisedThinking commented 2 years ago

Well if only DMA-BUF is needed then it might could work with the 470er series - it should be in https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-470-Wayland-Friendly

But if you compare the readme files it's not mentioned - at least for EGL & Wayland

A Wayland EGL external platform library (/usr/lib/libnvidia-egl-wayland.so.1) and its corresponding configuration file ( /usr/share/egl/egl_external_platform.d/10_nvidia_wayland.json ); this library provides client-side Wayland support on top of the EGLDevice and EGLStream families of extensions, for use in combination with an EGLStream-enabled Wayland compositor:

Darkspirit commented 2 years ago

Firefox' EGL-Dmabuf-VAAPI requires hardware WebRender which requires OpenGL 3.2.

IIUC, Gbm is primarily needed for EGL-Gbm-Dmabuf-WebGL, but FEATURE_DMABUF on about:support means Gbm+Dmabuf. "Failed to configure" comes from here: https://searchfox.org/mozilla-central/rev/3de56eb5f266f523340e739ae1b53258e0a95dfe/gfx/thebes/gfxPlatformGtk.cpp#217

VAAPI decision is made here: https://searchfox.org/mozilla-central/rev/3de56eb5f266f523340e739ae1b53258e0a95dfe/widget/gtk/DMABufLibWrapper.cpp#275

philipl commented 2 years ago

Also, The EGL extension to export the dma buf was only added in 495.

guihkx commented 2 years ago

RIP then. 🥲

I'm pretty sure NVIDIA won't be adding new features to R470 because it's a LTS branch. Feel free to close this if you wish, @elFarto.

Darkspirit commented 2 years ago

Some further background info: If I understand correctly, media.ffmpeg.vaapi.enabled also enables dmabuf-textures for software decoding (it can be disabled with media.ffmpeg.dmabuf-textures.disabled). If a codec is not supported by the VAAPI hardware decoder because

Firefox uses the software decoder, but tries to use EGL+Gbm+Dmabuf to avoid copies between processes which should improve performance for high res videos. (dmabuf-textures did work in the content process back then, it might be broken unnoticed in the RDD process, I haven't tested yet. It might even not be needed anymore.)

elFarto commented 2 years ago

Also, The EGL extension to export the dma buf was only added in 495.

eeeh..not so fast there. The output of eglinfo on my GeForce 760 with the 470.94 driver contains these:

EGL_EXT_image_dma_buf_import EGL_EXT_image_dma_buf_import_modifiers EGL_MESA_image_dma_buf_export

And after finally convincing my second machine to build mpv, and can confirm this library does work (with mpv at least).

It doesn't work too well with a Prime/Optimus setup, I get this error, which I believe is from mpv even though it's our logging function:

[21052-21058] ../src/export-buf.c:  36                    debug [EGL] eglCreateImageKHR: dri2_create_image_khr_texture (3003)

But if I force mpv to use the NVIDIA EGL backend (this library already picks the correct EGL device), it does work, and it does display the video, which is hooked up to the Intel iGPU.

So, there is hope for getting this working on 470 within Firefox, if it can enable DMA-BUF without GBM, and you're not using a Optimus setup.

Just for fun I tried to see if it'd work with VLC, but:

And after that VLC falls back to VDPAU then it works. And yes, I understand there's no point in using this with VLC. I was just curious... Is this expected not to work?

philipl commented 2 years ago

That log output says VLC is using the X11 interop:

[00007f4f580069c0] glconv_vaapi_x11 gl error: vaDeriveImage: operation failed

which isn't supported. I'd say surely VLC must support dma-buf interop but it has a weird relationship with hwaccel so anything is possible.

elFarto commented 2 years ago

This library has only been tested with MPV and Firefox. It should work with anything that uses ffmpeg to talk to VA-API, but anything else that uses it directly will likely use parts that are unimplemented. There's little point for any application that can use NVDEC (or VDPAU I guess) directly to use this library.

I'm not against getting it working in other applications, like Chrome, but that's a future goal.

LordTermor commented 2 years ago

Setting widget.dmabuf.force-enabled to true helped 2060 SUPER to be able to work with 470 driver. Maybe it's worth adding this to README? (I'm not sure about pre-Maxwell GPUs though)

elFarto commented 2 years ago

@LordTermor I'm surprised that made a difference, are you sure it was using the driver with that option enabled? Firefox specifically checks for GBM to be present before enabling VA-API, so we'll need to patch Firefox first, before we can get it to work.

LordTermor commented 2 years ago

Firefox specifically checks for GBM to be present before enabling VA-API

Even on X11? I'm sure that's what did the trick for my friend.

elFarto commented 2 years ago

Yes, it always checks.

LordTermor commented 2 years ago

So here are the screenshots that show the difference. Tell me if anything else is needed. изображение изображение

elFarto commented 2 years ago

That does certainly look like it's working. I'll have to do some more investigation as to why that option seems to help. Can you run firefox with the MOZ_LOG="PlatformDecoderModule:5" environment variable set, and post the log?

LordTermor commented 2 years ago

firefox.log

Here you go.

elFarto commented 2 years ago

Thanks for that, it does actually seem to be working correctly.

elFarto commented 2 years ago

Well, I've finally got around to testing this on the appropriate hardware, and it does infact work. I'm still a little confused as to why it does. In theory attempting to open a GBM device on the NVIDIA render node shouldn't work on this version (this was the bit I was expecting to fail), but it works just fine.

I'm going to add this to the README as it might help some people.

@LordTermor Can you post what version of MESA you have installed? And the contents of /usr/lib64/gbm (or /usr/lib/gbm depending on how your distro is setup)?

@guihkx Can you retry with the config option widget.dmabuf.force-enabled set to true? And post a log with MOZ_LOG="Dmabuf:5,PlatformDecoderModule:5" set if it doesn't work?

guihkx commented 2 years ago

Didn't work for me... I even made sure to test it on a fresh Firefox profile, but nada:

I'm pretty sure the 470 driver doesn't install a libgbm.so.1

elFarto commented 2 years ago

libgbm.so.1 is part of MESA, not the driver. The NVIDIA driver installs a backend into /usr/lib64/gbm/. Can you check what version of MESA is installed?

Indeed, sorry.

Darkspirit commented 2 years ago

https://bugzilla.mozilla.org/show_bug.cgi?id=1736761 ("MESA-LOADER: failed to open nouveau") was the reason why versions below 495 have been blocklisted for FEATURE_DMABUF (Dmabuf+Gbm).

elFarto commented 2 years ago

Can you run NVD_LOG=1 vainfo and paste the output? Specifically, this error: We're missing DRM render device! doesn't make any sense, the 470 driver creates a render node.

I also tried running Firefox with MOZ_WAYLAND_DRM_DEVICE=/dev/dri/card0 and at least that made the D/Dmabuf Failed: We're missing DRM render device! message disappear, but I suspect that's very wrong judging by output I got, lol

I've put in a gist because it's a bit long: https://gist.githubusercontent.com/guihkx/c539e654361e5d63e9e9a5fa91de5ae7/raw/8832a39a5d86f7a102e507c4019ca4ae6c121b66/firefox.txt

elFarto commented 2 years ago

Can you retry that with the latest version of the driver from git? You've got the interesting combination of modeset=Y and Unable to export to dma-buf.

@LordTermor Can you post what version of MESA you have installed? And the contents of /usr/lib64/gbm (or /usr/lib/gbm depending on how your distro is setup)?

pacman -Q mesa && ls -l /usr/lib/gbm/

And the MOZ_LOG="PlatformDecoderModule:5,Dmabuf:5" firefox log: firefox-dmabuf.log

elFarto commented 2 years ago

findCudaDisplay Checking device file: (null)

Ok, now I'm really confused. There's something very odd about this setup. The NVIDIA EGL driver isn't giving you the DRI device for that EGLDevice, but there does appear to be one there. Can you run nvidia-bug-report.sh and attach the resulting file?

ls: unable to access '/usr/lib/gdm/': There is no such file or directory

gdm?

guihkx commented 2 years ago

Can someone please share with me the output of:

ls -la /dev/dri/renderD128

I'm pretty sure mine has the wrong permissions and when I run Firefox with MOZ_WAYLAND_DRM_DEVICE=/dev/dri/renderD128 I get:

[Parent 287367: Main Thread]: D/Dmabuf Failed to open drm render node /dev/dri/renderD128 error Permission denied

It's my own fault, some time ago I was messing with vglserver and the script I ran added group restrictions to /dev/dri/renderD128. I know I can add myself to that group, but I suppose I'd have to logout/login and I can't do that right now. Plus I want to restore the original permissions... Thx

elFarto commented 2 years ago

ls -la /dev/dri/renderD128

guihkx commented 2 years ago

My sincere apologies to anyone who helped me debug this issue.

TL;DR: The cause of the issue was incorrect permissions in /dev/dri/renderD128.

Screenshot of HW decoding working on Firefox now (no additional steps needed, I only followed the instructions in the README file):

Oops, lost this letter during copying and mistyped it accidentally. Sure it's gbm.

But anyway, great that it actually works.
