i don't really do games or other fancy multimedia stuff, except for watching movies occasionally. i seem to have issues playing videos online or offline. perhaps they are to do with some particular movies, or formats, or codes. i don't understand enough..

i do have 3d acceleration as per the wiki.

Code:

$ glxinfo | grep rendering
direct rendering: Yes

with vo=vaapi, i get a blank black mpv window.. and lots of these error messages

Code:

$ mpv -vo vaapi videofile
...

with vo=opengl-hq, i can see the video playing in the mpv window.. and some warning messages

Code:

i'm afraid, i don't really understand all those messages.

should i globally enable any flags - perhaps (drm?) egl gles opengl vaapi - for all packages and recompile everything? if they are not required everywhere, i'd rather not.

Hi josephg

I'm no expert and can't help you with an explanation of those errors,
But you can try to enabling vaapi and x264 and x265 om ffmpeg in package.use
I do not see those errors when i play a video file on my Laptop.

Sorry about that josephg, :oops:

Install

Code:

Code:

I also like to use

Code:

app-portage/gentoolkit

command

Code:

equery u ffmpeg

Which gives more descriptive information.
Cheers.

i liked that concise output with all (de)selected flags in one line. hence why i asked. thank you.

yes i have equery. just one problem i'm facing is the output can't be parsed, or i'm not doing it right. for eg,

Code:

$ equery u ffmpeg | grep -i decod

returns nothing

Hi josephg,
try this

To see the flags that were set i use this command.

Code:

equery u ffmpeg | grep -i ^+

And for Unset i use

Code:

equery u ffmpeg | grep -i ^-

Or eg to check cpu flags available

Code:

equery u ffmpeg | grep -i cpu
-cpu_flags_x86_3dnow
-cpu_flags_x86_3dnowext
+cpu_flags_x86_avx
-cpu_flags_x86_avx2
-cpu_flags_x86_fma3
-cpu_flags_x86_fma4
+cpu_flags_x86_mmx
+cpu_flags_x86_mmxext
+cpu_flags_x86_sse
+cpu_flags_x86_sse2
+cpu_flags_x86_sse3
+cpu_flags_x86_sse4_1
+cpu_flags_x86_sse4_2
+cpu_flags_x86_ssse3
-cpu_flags_x86_xop
+cpudetection

or to check which cpu flags are active.

Code:

equery u ffmpeg | grep -i ^+cpu
+cpu_flags_x86_avx
+cpu_flags_x86_mmx
+cpu_flags_x86_mmxext
+cpu_flags_x86_sse
+cpu_flags_x86_sse2
+cpu_flags_x86_sse3
+cpu_flags_x86_sse4_1
+cpu_flags_x86_sse4_2
+cpu_flags_x86_ssse3
+cpudetection

That's how i use grep, but there are grep experts that can instruct you with better examples i'm sure. :wink:

thank you again. but let me clarify what i was trying.. if i "equery u ffmpeg", i get a very long list of each use flag per line with a "description" at the end of each line. if i "equery u ffmpeg \| grep cpu", i don't see that "description" at the end of each line. i would like to see the "description" too, when i grep it. but perhaps this is more a portage query, i should ask in that sub-forum. _________________ "Growth for the sake of growth is the ideology of the cancer cell."

ok, i found the answer. equery needs --no-pipe like so.

Code:

$ equery --no-pipe u ffmpeg | grep cpu
- - cpu_flags_x86_3dnow : Use the 3DNow! instruction set
- - cpu_flags_x86_3dnowext : Use the Enhanced 3DNow! instruction set
- - cpu_flags_x86_avx : Adds support for Advanced Vector Extensions instructions
- - cpu_flags_x86_avx2 : Adds support for Advanced Vector Extensions 2 instructions
- - cpu_flags_x86_fma3 : Use the Fused Multiply Add 3 instruction set ([fma] in cpuinfo)
- - cpu_flags_x86_fma4 : Use the Fused Multiply Add 4 instruction set
+ + cpu_flags_x86_mmx : Use the MMX instruction set
+ + cpu_flags_x86_mmxext : Use the Extended MMX instruction set (a subset of SSE) ([mmxext] or [sse] in cpuinfo)
+ + cpu_flags_x86_sse : Use the SSE instruction set
+ + cpu_flags_x86_sse2 : Use the SSE2 instruction set
+ + cpu_flags_x86_sse3 : Use the SSE3 instruction set ([pni] in cpuinfo, NOT ssse3)
- - cpu_flags_x86_sse4_1 : Enable SSE4.1 instruction support
- - cpu_flags_x86_sse4_2 : Enable SSE4.2 instruction support
+ + cpu_flags_x86_ssse3 : Use the SSSE3 instruction set (NOT sse3/pni)
- - cpu_flags_x86_xop : Enable the XOP instruction set
- - cpudetection : Enables runtime CPU detection (useful for bindist, compatibility on other CPUs)

without it,

Code:

$ equery u ffmpeg | grep cpu
-cpu_flags_x86_3dnow
-cpu_flags_x86_3dnowext
-cpu_flags_x86_avx
-cpu_flags_x86_avx2
-cpu_flags_x86_fma3
-cpu_flags_x86_fma4
+cpu_flags_x86_mmx
+cpu_flags_x86_mmxext
+cpu_flags_x86_sse
+cpu_flags_x86_sse2
+cpu_flags_x86_sse3
-cpu_flags_x86_sse4_1
-cpu_flags_x86_sse4_2
+cpu_flags_x86_ssse3
-cpu_flags_x86_xop
-cpudetection

that's what i was missing

personally, i think this should be the default behaviour!

now i can get this working..

i see debian recommends not using xf86-video-intel driver.

Quote:

The use of this driver is discouraged if your hw is new enough (ca. 2007 and newer). You can try uninstalling this driver and let the server use it's builtin modesetting driver instead.

so i did a bit of research and saw lots of articles suggesting improved performance after removing this driver. so i did

since i have VIDEO_CARDS="intel" in make.conf, i had to

/etc/portage/package.use:

x11-base/xorg-drivers -video_cards_intel

after rebooting, i stil have

Code:

$ glxinfo | grep rendering
direct rendering: Yes

and now glxgears consistently gives me 500+ FPS

where before i was getting a tad less than 60 FPS

That just means the latter had vsync and modesetting doesn't, nothing about 3D. You'll need to check glxinfo -B doesn't mention softpipe to be sure.

You're probably missing USE=glamor on xorg-server.

thank you Ant P.

i now have this.. xorg-server with glamor without intel, and no xf86-video-intel. glxgears has gone back down to it's usual 59+ FPS. this kernel modesetting driver is doing everything that the intel driver did, and perhaps more..

Code:

and everything's working great.. perhaps gentoo (like debian and others) should change intel driver recommend?

so i have now removed intel driver

it feels nice to get rid of stuff

should i change my

/etc/portage/make.conf:

VIDEO_CARDS="intel i965"

because if i keep the above, then i have to

/etc/portage/package.use:

x11-base/xorg-drivers -video_cards_intel

My understanding is that if your chipset is Gen 4 or better that is what you would use.

But others may be better equipped to give a firm answer.

i think some of my mpv/vaapi issues have been resolved. i can see video with vo=vaapi, but no hardware decoding

Code:

$ mpv -vo vaapi movie.mp4
Playing: movie.mp4
(+) Video --vid=1 (*) (h264)
(+) Audio --aid=1 --alang=eng (*) (aac)
libva info: VA-API version 0.38.1
libva info: va_getDriverName() returns 0

libva info: Found init function __vaDriverInit_0_38
libva info: va_openDriver() returns 0
AO: [alsa] 48000Hz stereo 2ch float
[vaapi] Decoder profile 'VAProfileH264High' not available.
Using software decoding.

[osd/libass] fontconfig: cannot find font 'sans-serif', falling back to 'DejaVu Sans'
AV: 00:00:01 / 01:59:17 (0%) A-V: 0.000

Code:

$ vainfo
libva info: VA-API version 0.38.1
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/va/drivers/i965_drv_video.so

vainfo: VA-API version: 0.38 (libva 1.6.2)

vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointVLD

can i add VAProfileH264High and/or enable hardware decoding without messing about too much? i see this wiki page, but i'm having trouble understanding it.

You shouldn't need all that, just the ~arch versions of libva/libva-intel-driver.

ok, i found the answer. equery needs --no-pipe like so.

that was what i was missing

personally, i think this should be the default behaviour!

That's indeed a better output,
Good to now this one josephg

so i added them to package.keywords, and did an emerge again. i don't see those use flags or any H264 profile or hardware decoding.

Code:

# emerge -1 libva libva-intel-driver

These are the packages that would be merged, in reverse order:

this thread is fascinating and disturbing Is it the consensus that it is now a bad idea to install xf86-video-intel driver because it is completely unnecessary and may worsen performance? (someone should update the gentoo wiki intel guide in that case asap) 'cause that is a somewhat radical step (maybe it explain why there's no version 3 of the driver ) _________________ .... there is nothing - absolutely nothing - half so much worth doing as simply messing about with Linux ...

I think the wiki is already updated, look here: https://wiki.gentoo.org/wiki/Intel#xorg.conf (under Alternate Driver for Gen 4+ -- Modesetting -- Experimental)

it is not just about performance, but additional functionality too. and apparently intel hasn't updated that driver for years.
now that it is in the mainline kernel, we should see more activity and further development.
