 Posted: Thu Oct 24, 2024 2:57 pm Post subject: execution of ffmpeg is taking more time in gentoo than other |
 |
|
Hi I am Rupesh from India and I brought a new PC with AMD Ryzen zen3 5500GT and Asus prime 450 MK2 motherboard. I installed four Linux Operating Systems including gentoo linux and one Windows 11 Operating System. I installed ffmpeg tool along with libaom. Everything is working fine except there is something wrong with ffmpeg execution in Gentoo Linux.
I love working with Linux and Unix Operating Systems and I have lot of disk space and so I have installed four Linux Operating Systems and they are
1) Debian Linux testing Trixie
2) Fedora 40
3) Arch Linux
4) Gentoo Linux with systemd and desktop stage 3
At first I have installed Zen kernel through genkernel utility passing the parameter all.
After installation I have compiled the same ffmpeg source code which is cloned from git and with the same options which includes the following
--enable opencl
--enable opengl
--enable libaom
--enable AMF
--enable gnutils
Etc.,
I have some h264 mp4 files and I want to convert them into aom codec through ffmpeg and libaom.
I tested to convert those same files into aom codec using the same ffmpeg script but ffmpeg in gentoo Linux is taking too much time compared to ffmpeg in remaining Linux Operating Systems.
During the compilation of ffmpeg in gentoo linux I have installed packages related to amdgpu and rocm but unfortunately rocm-opencl-headers failed in installation.
After that I installed clinfo and ran it and it is showing message as Full profile, platform AMD etc.,.
Ffmpeg in other distributions is taking 45 minutes to convert 110 MB h264 mp4 to aom codec mp4 but unfortunately ffmpeg in Gentoo Linux is taking more than 100 minutes.
I can't understand what's wrong with ffmpeg in Gentoo Linux.
Even I have installed amdgpu_top_gui and opened it and it is showing a lot of information about my APU.
If I have not installed anything which is required for ffmpeg to run properly it must fall in compilation but it compiled successfully but it is not working fine.
Kindly try to suggest how to make ffmpeg to work properly and I am ready to provide any diagnostic information of the commands provided by you.
Regards,
Rupesh.

Make sure you have this set up: https://wiki.gentoo.org/wiki/CPU_FLAGS_*
Since you manually built ffmpeg from source, instead of using an ebuild, I'm going to assume you're a beginner and tell you to also make sure you have sane CFLAGS and CXXFLAGS (like "-O3 -march=native"). |

Hi Rupesh,
From the magnitude of the difference, I doubt it's related to compiler flags unless you've built the system with "-O0"!
What CPU frequency governor are you using on Gentoo?
To check, use:
| Code: | | # cpupower -c all frequency-info |
(If you get "command not found", you will need to install cpupower with 'emerge sys-power/cpupower'.) This will return a lot of information about your CPU clock frequency, including its current value, which driver is controlling it, which frequency governors are available and which one is in use.
I suspect you may be using the "powersave" governor, which locks the CPU at its slowest speed.
If so, you will need to switch to a different one. If "schedutil" is available, that generally works quite well:
| Code: | | # cpupower -c all frequency-set -g schedutil |
As it's a Zen system, however, there is an AMD-specific cpufreq driver available; I don't know whether this may take over the function of the governor too as the intel_pstate driver does. I don't have access to modern AMD hardware to test it so someone else may have to advise you on how to configure it if this is in use.
Let us know what you find.
Hope this helps,
Stephen |

build@localhost ~ $ sudo cpupower -c all frequency-set -g schedutil
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?

ffmpeg is particularly sensitive to cpu flags, as there are lots of hardware instructions tailored for the sort of vector processing involved (SSE4.2, and host of other flags).
It's almost certainly worth (a) getting good CFLAGS suitable for the hardware and use-case (a whole discussion in itself, visible all over the forums), and (b) using the output of cpuid2cpuflags to tailor make.conf, as ffmpeg is dependent on them too.

For zen3 and later, when using the amd p-state driver you'll get the best results using the powersave governor.
It's worth enabling perfcore on the kernel command line too<< I don't know how many of the p-state features were backported to the 6.6 series of kernels, so I stick to >=6.9.1.
Do not enable any bios overclock of the CPU it gimps the drivers boost function, it will dynamically overclock each core to it's individual capabilities itself. The time boost frequencies can be applied is related to individual core temperature, so a well (thermally) connected cooler that can quickly remove thermal gradients becomes a performance factor (read: don't use the stock cooler for best results). |

Kindly try to suggest how to make ffmpeg properly work in Gentoo.

If an application in your Gentoo Linux has performance problems, this can have two possible causes: The application itself has been “badly” compiled, or your Linux system / kernel is “unfavorably” configured. For example, you have a setting that is impossible (because the two use flags are mutually exclusive = you can only activate one of them):
| Code: | | USE="... systemd elogind ..." |
We need a lot more information to be able to check your configuration comprehensively:
1. Give us all 3 files mentioned here:
https://wiki.gentoo.org/wiki/User:Pietinger/Overview_of_System_Information
(note the reference to wgetpaste for your "dmesg"-output)
2. If you have configured the kernel yourself manually, we need its .config (also with wgetpaste)
3. The output of (also with wgetpaste):
| Code: | | # grep -r --exclude-dir=savedconfig "" /etc/portage |

| To elaborate on what others have said, this essentially can't be Gentoo "specific" other than kernel configuration if you're building manually from source and not using the ebuilds. |

I haven't compiled kernel source code manually.
After extraction of stage 3 tarball I installed kernel sources bin package and installed other packages like iwd, dhcpcd etc ,.
After that I booted successfully into my system and in non root account
1) I installed Zen kernel package and genkernel utility.
2) I made a symbolic link as linux-->zen sources under /usr/src directory.
3) I issued the command sudo genkernel all
4) Finally the above utility compiled and installed Zen kernel 6.10
But at that time it shown error as something went wrong but I neglected.

Add the output of "cpuid2cpuflags" to "/etc/portage/make.conf", then rebuild all affected packages with "emerge -uDUav @world". |

Is there any need to install gentoo linux from the beginning and if so please give correct use flags.
I want to install all the available desktop environments and so how to add use flags which will not conflict in future.

No. Only a need to carefully read the available documentation. Gentoo Linux is an advanced distribution, better suited for advanced users who pay attention to details.
You can't just copy-paste some commands and call it a day. You need to understand all the intricate details of what makes it tick, in order to have full control over it. This is why Gentoo is your last Linux distro, not your first. |

Yes, that's what I meant to say when I mentioned cpuid2cpuflags some way ago. Actually, for this particular issue, just rebuilding ffmpeg will suffice:
(Specifically, the ffmpeg build is sensitive to avx2, fma3/4, xop, avz, sse2/3/4_1/4_2, mmext, 3dnow/ext on x86 archictures. Without those specified in CPU_FLAGS_X86 in make.conf, ffmpeg will be severely limited.)

rupeshforu3,
I asked for
| Code: | | # grep -r --exclude-dir=savedconfig "" /etc/portage |
and it is really important, because exactly there is a problem:
| Code: | | --- Invalid atom in /etc/portage/package.use/00cpu-flags: aes |
We need to set this portage information correctly and then recompile ffmpeg. See also:
https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Base#CPU_FLAGS_.2A
If not already done, do at first:
| Code: | # emerge -1 cpuid2cpuflags
# cpuid2cpuflags |
and compare this with your file /etc/portage/package.use/00cpu-flags
Later you have to re-emerge ffmpeg .
Moderator note: I do not tolerate jokes in a pure support thread. Help purposefully or keep your fingers still.

He uses libaom, for which ffmpeg acts like a simple wrapper, so he needs to rebuild libaom with those CPU-specific USE flags in order to get some serious SIMD speed-ups during AV1 encoding.
Much easier for a beginner to just rebuild everything affected by new USE flags, instead of having to understand all that. |

Indeed, the */* is missing; re-run the command from the handbook | Code: | | echo "*/* $(cpuid2cpuflags)" > /etc/portage/package.use/00cpu-flags |
then | Code: | | emerge -uDNav world |

Seeing as you seem to have enough going on with new kernels and rebuilding with CPU_FLAGS set, I did the legwork on this, but will tag where everything comes from. Default use flags are set by your profile, from your first post | Quote: | | 4) Gentoo Linux with systemd and desktop stage 3 |
To add use flags for both gnome and plasma the easiest way is to look through the profiles for default/linux/amd64/23.0/desktop/gnome/systemd and default/linux/amd64/23.0/desktop/plasma/systemd and make all these "default changes" yourself so any conflicts are manageable.
For gnome this looks like | /etc/portage/package.use/for_gnome: | #from /var/db/repos/gentoo/profiles/targets/desktop/gnome/make.defaults

If at some stage you decide you like having "all the desktop environments around" I'd suggest you set the default/linux/amd64/23.0/desktop/plasma/systemd profile (because of the use.force), symlink the /var/db/repos/gentoo/profiles/targets/desktop/gnome/{systemd/}package.use files to /etc/portage/package.use, and stick the contents of the gnome/make.defaults in your make.conf, apart from the gnome/make.defaults your settings will keep up with profile changes that way. If you do get conflicts portage will flag them and the forum users here will help translate portage's output to "human readable" for you if needed.
A note about ffmpeg: An ebuild for the git version of ffmpeg is in the portage tree (as media-video/ffmpeg-9999), I appreciate you might not be using the same git repo, but I strongly suggest you install it so portage (or you) has a chance to pull in all the deps with the correct use flags set. It's also behind a ** keyword and package.mask, so it'll be a nice learning exercise.

~20000 packages in the portage tree, only ~200 support specific cpu_flags_x86_ use flags, Rupesh has >=2 of them on a fresh system, can't help but feel a little sorry for the guy... |

When I issue the following command I am getting error as permission denied.
echo "*/* $(cpuid2cpuflags)" > /etc/portage/package.use/00cpu-flags

You need to be root to work on portages system files*, if you've set-up sudo, use | Code: | | echo "*/* $(cpuid2cpuflags)"|sudo tee /etc/portage/package.use/00cpu-flags |
, if not just use su in a terminal beforehand and enter the root password, then the command will run.
*If you are letting normal users run portage then chowning /etc/portage to :portage with g+w perms can make sense, but that's for another thread. |

Package media-video/ffmpeg-9999 not found.
I think it is in eapi 8.
At present I am not using eapi 8 and so can you suggest how to use eapi 8.
