Hello all, I am using NetBSD 9 on my laptop, I installed firefox and mpv and i noticed that video is slow. In youtube I noticed it slow particularly when I am in fullscreen. Mpv reported the following messages when trying to reproduce a video: https://bsd.to/XS4S My laptop has two video cards but I think NetBSD is only using the integrated video card. I provide my dmesg output here: https://bsd.to/Aof2 Also my /proc/cpuinfo is this one: processor: https://bsd.to/uzjK Can somebody help me understand what may be the cause of this? Or how can I fix this? I didn't touch any of the Xorg config stuff. Hope you can help me, was really excited to use NetBSD on my driver laptop. Thanks

netbsdnoob Does it help if you install /multimedia/libvdpau ? My bad, it should already be installed as a dependency of mpv

pin Actually i found out that libvdpau was not installed.... Anyway after installation, I retried with mpv and the situation is worse, now i have no video. Mpv gives me the following error messages: https://bsd.to/jMJp Any idea? what should I do? It seems like it is not finding the .so, but I am sure I installed libvdpau. What should I do?

pin Any other idea on how to solve this?

netbsdnoob Nope 🙁 Let's hope somebody else does. You could try posting on the mailing lists, https://mail-index.netbsd.org/netbsd-users/tindex.html

The kernel driver is active but Xorg is not using GPU acceleration at all. Please post output of glxinfo, cat /var/log/Xorg.0.log, ls -l /dev/dri. Is your user account a member of the wheel group?

nia Ok here is the requested infos: glxinfo: https://bsd.to/KbMm cat Xorg.0.log: https://bsd.to/pmcV ls -l /dev/dri output: https://bsd.to/yxDL id: https://bsd.to/MBr3 Any idea on this?

Actually, I think the problem wasn't what I expected. I think we've already fixed it for the next pkgsrc branch... The mpv package was mistakenly built without EGL support. Can you try -vo=sdl for mpv?

nia The output of mpv can be found here: https://bsd.to/Dz6J The issue is the same, the video is extremely slow. Any other ideas on what could be the problem? I am lost.

netbsdnoob As you've introduced me to Vulfpeck , I'll try to help you. Download the video using youtube-dl , then play it locally using mpv . Press I . How many frames are dropped? Using my lowest CPU frequency, 800 MHz, playing Dean Town , I see 7 output frames dropped at the end of the video with vo=sdl , and 425 dropped output frames with vo=xv (the default), but, no noticeable slowdowns in either case.

rvp Ok i am about to do this test, but in the meanwhile I wanted to share additional info when I tried to download a youtube video with youtube-dl and tried to play with vlc. VLC seems not able to work at all with the following errors: https://bsd.to/WKOt Are the issues related? P.S.: I am about to try your suggestion now.

Slow Video Problem

rvp I did it just now, it gives about a 20% reduction in CPU usage with ffplay4 for me. Committed it 🙂

Gotta test the other players now, xine and vlc...

What a load of work that is... 🇦🇿Azerbaijan🇦🇿 thanks you.

netbsdnoob

nia Really! Thanks from all the users of azerbaijian!

netbsdnoob

rvp are you an azeri brother too ?

rvp

netbsdnoob are you an azeri brother too ?

Absolutely! And, I offer these useful Azerbaijani phrases for the non-Azeris on this board. Please use them in Baku:

Mənim evimə xoş gəldiniz, ancaq xahiş edirəm qorilinizi çöldə qoyun.
(What a wonderful house you have, Madam.)
Oh, mənim! Cənab Şaxta baba, orada nə qədər böyük bir çəkiciniz var!
(Excuse me, can you direct me to the railway station?)
Oi, o pis görünüşlü çəkicini yerə qoy və əvəzinə bu ləzzətli mərci şorbasını iç.
(Waiter! The coffee in your establishment is most excellent!)
NetBSD üçbucaqlı siçanlarla doludur!
(NetBSD is a clean and portable operating system.)

netbsdnoob

rvp Can't wait to see more azeris brothers on NetBSD.
Well, the sentences are not translated correctly, but I see the joke!
They are very funny!

The fourth sentence is particularly useful especially if somebody is hacking on NetBSD in Baku, so the correct
translation would be:
NetBSD təmiz və portativ bir əməliyyat sistemidir!

netbsdnoob

rvp I think a lot of people here is from azerbaijian actually!
One day NetBSD will have its official guide in Azerbaijijani!!! 🇦🇿 🇦🇿

rvp I think Twitter can't property translate your 4th point :

oui

NetBSD on Intel HD Graphics has always had slightly choppy/slow video playback with screen tearing by default for me. Tested on Intel HD Graphics 530 and 4400. The way I always fix it is changing the default Xorg settings (accelmethod from sna to uxa) and force enable acceleration in Firefox by going to about:config and toggle the layers.acceleration.force-enabled to true - video playback and scroll in Firefox etc gets butter smooth. Maybe this could help improve your situation a little bit?

I don't remember exactly which Xorg option it was, but on my previous computer changing settings like "SwapbuffersWait", "TripleBuffer", "Vsync" etc to false also improved my situation.

You can generate a default Xorg file and play with the settings by running X -configure.

It's also worth noting that trying a current kernel might also help.

netbsdnoob

oui Once i generate my config with X -configure

how can i put that configuration in action?

netbsdnoob

oui well if i enable layers.acceleration.force-enabled firefox just crashes with a segmentation fault.
=(
I tried tinkering with xorg.conf and set accelmethod to uxa as you suggested.

No improvements at the moment.

rvp

Jay That's what I meant, except for the missing pronoun: Your NetBSD is full of triangular mice.

Since I speak as much Azerbaijani as Borat speaks Kazakh, the only way I could be sure the sentences were funny in both English and Azerbaijani was to translate forwards, then back again. Even then, I had to tweak the phrases a bit because Google doesn't translate colloquial speech correctly: "Drop that spanner" (my original phrase) always got translated into "Throw away that key", so I made the sentence "Put down that hammer" which came back OK, but doesn't have the proper ring to it. Similarly, it was originally "rectangular gerbils", but that came bac all wrong.

The inspiration is, of course, Monty Python's Dirty Hungarian Phrasebook

rvp Since I speak as much Azerbaijani as Borat speaks Kazakh

🤣 Nice 👍️

netbsdnoob See Chater 9 of the NetBSD Guide, https://www.netbsd.org/docs/guide/en/chap-x.html

netbsdnoob

pin Thanks Sir.

oui

netbsdnoob Have you tried using a current kernel?

netbsdnoob

oui That will be the next thing I will do.
But why? Were there a lot of improvements for i915 in the latest kernel?
So basically sysupgrade auto <link-to-current>
and reboot?

netbsdnoob No, this will update the other sets to current also. You can test the current kernel alone.

oui

netbsdnoob I don't remember exactly what changes was added but there has been updates to older Intel CPUs. For reference Xorg in NetBSD 9.0 is broken on my Optiplex 3020M machine using a Intel Core i3 Haswell so I need to run a current kernel.

Just download a generic kernel "netbsd-GENERIC.gz" from here: http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/amd64/binary/kernel/

First backup your current kernel:
mv /netbsd /netbsd.old

unzip, rename the downloaded kernel to "netbsd" and move it to root. Reboot and that's it.

Really, I don't know if I should be writting this to be honest.

WARNING: I shall not be considered responsible if anything breaks.

Fetch the current kernel from here, http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/amd64/binary/kernel/
Assuming you have it in your Downloads directory, verify the checksum and unpack it.

cd Downloads
cksum -a MD5 netbsd-GENERIC.gz
gunzip netbsd-GENERIC.gz

Now, in the same directory as root/su

mv netbsd-GENERIC /
cd /
chmod 755 netbsd-GENERIC
chown root netbsd-GENERIC
mv netbsd netbsd_9
mv netbsd-GENERIC netbsd
reboot

If you want to revert to the original kernel, again as root/su

cd /
mv netbsd netbsd_HEAD
mv netbsd_9 netbsd
reboot

Be carefull.

oui

pin Good timing, tror vi svarade samtidigt 😂

@netbsdnoob As Pin mentioned though, be careful. If something went wrong and you can't boot the system, refer to this guide (the bottom of the page): http://www.netbsd.org/docs/guide/en/chap-kernel.html#chap-kernel-something-wrong

netbsdnoob

pin No worries I can break my machine! I do not have sensitive data on that machine and it's being used just to test.
