Porteus v5.0rc1 problems

[chromer]

due to lack of libgtop on Porteus 5 rc1 Cinnamon , some of applets and desklets not loading and not working...( like : CPU monitor or Memory Monitor applet ).
On Porteus 4 and Aporteus this library is natively present and no problem.

chromer, thanks. I'll add it back in the next release.

There are TWO Browser Selection and Update Tool items in the menu.

Code: Select all

guest@porteus:~$ ls /usr/share/applications/*browsers*
/usr/share/applications/browsers.desktop*
/usr/share/applications/gtk-update-browsers.desktop*
guest@porteus:~$

There are TWO Browser Selection and Update Tool items in the menu.

See here:

we only need two:
browser.desktop which is overwritten when a browser in activated
and one of the other two(since their contents are identical)(probably gtk-update-browsers.desktop to avoid future confusion)

As Blaze has pointed out, Slack current has finally updated ffmpeg package. So I decided to include it in our current xorg and try an experiment with new mpv.

Here are the changes:
1- ffmpeg updated to 4.1.4 (Slack current)
2- mpv updated to 0.29.1 (built with Slackbuild)
3- changed mpv.desktop command call to:

Code: Select all

mpv --player-operation-mode=pseudo-gui --hwdec=auto --video-sync=display-resample --no-osd-bar --audio-file-auto=fuzzy -- %U

As you can see, hwdec flag is now set to auto. So now we can provide hardware video decode acceleration out of the box to almost all users. I tested on both Intel video card and Nvidia video card (with official drivers) machines and it worked nice! However, users with Nvidia cards that are using Nouveau drivers (Mesa) still need to export a system variable (more here) -- I don't have a decent solution for this right now, so I accept suggestions. And, of course, since I don't have an AMD videocard, I can't test it.

Please, report your results: press i when watching videos like this and check if hwdec (hardware decode) is enabled and if performance is acceptable (low CPU usage is a good sign)

P.S.: when using this updated xorg module you'll notice that video thumbnails will not appear anymore, so I recommend updating ffmpegthumbnailer here.

See here:

browser.desktop which is overwritten when a browser in activated

A browser is active and being used to post this and the menu still has 2 browser entries.

Code: Select all

guest@porteus:~$ ls /mnt/live/memory/images/f*
/mnt/live/memory/images/firefox-60.7.2esr-x86_64-en-US-1.xzm:
usr/  var/

/mnt/live/memory/images/flashplayer-plugin-32.0.0.223-x86_64-1.xzm:
license.pdf  usr/  var/
guest@porteus:~$guest@porteus:~$ ls /usr/share/applications/*browsers*
/usr/share/applications/browsers.desktop*
/usr/share/applications/gtk-update-browsers.desktop*
guest@porteus:~$

As you can see, hwdec flag is now set to auto.

Since I seem to be a bit slow getting all this hardware acceleration and official Nvidia drivers right - my question:
does one need to export the vdpau variable to have vdpau hardware acceperation e.g. does the user have to do a

guest@porteus:/$ export VDPAU_DRIVER="nvidia"

like discussed in Porteus 5 + Nvidia official driver = no hardware acceleration on Mpv ?
Or will the newest DEs do that for the user by themselves?

Or can it not be done by the DE but e.g. must be part of the Nvidia driver module?

[fulalas]

@Rava, the idea is to set everything in xorg module so users don't have to do anything. The exception is when using Nvidia official drivers, because in this case the driver module will need to export the variable -- which is already happening with the update I suggested here.

fulalas with your new module...

Intel(R) Core(TM) i3-7100U CPU @ 2.40GHz

Code: Select all

mpv --vo=opengl --hwdec=vaapi /mnt/sda6/Downloads/bbb_sunflower_2160p_60fps_normal.mp4

Driver 'opengl' has been replaced with 'gpu'!

@raja, why are using this command line instead of the one I recommended above?

[raja]

No reason.

Whenever I use Netsurf, I use this command to watch videos from the net . VO will show yuv420p if I don't use vaapi. Just a habit.

[Rava]

which is already happening with the update I suggested here.

At least I get directed to the very first post of [HOWTO] make a xzm module driver for NVIDIA video card - can you please point out which post exactly you referring to?

[fulalas]

@raja, it would be great if you could test the command line I suggested because it uses an autodetect flag.

@Rava, I'm referring to the script that creates the driver module. Read the first post of that topic carefully.

[raja]

hwdec, auto selected to vaapi, with your command line. CPU usage more or less same or slightly lower.

Even double clicking to play video, MPV, auto selects vaapi and plays without any lag, with your new xorg module. In Porteus 4.0 this video crawls.

[Rava]

@Rava, I'm referring to the script that creates the driver module.

Okay, thanks for the info.

Read the first post of that topic carefully.

I am the author of that post, since I was the one to translate the instructions from Blaze original Russian post (with lots of help by automated translation software, since I do not speak Russian)

So, yes, I do know the script.
