 Posted: Tue Jul 02, 2024 6:48 pm Post subject: Is the use flag gstreamer recommend for a KDE desktop? |
 |
|
I am using a pure KDE environment and I have disabled any GTK/Gnome related stuff as far as possible. My profile is amd64/23.0/desktop/plasma/systemd. Years ago (probably a decade), I explicitly enabled the use flags gstreamer and ffmpeg on a global level. (Don't ask me why, probably, because some Gentoo Wiki recommended it back then.) My chosen profile does not enable GStreamer by default.
For some time now, whenever I try to upgrade my installation via "emerge --update @world", I get a warning that some updates have been skipped due to dependency conflicts. FFmpeg is held back at version 4 due to some indirect dependency related to GStreamer. More recently, GStreamer has also been dropped as a backend for Phonon, see https://bugs.gentoo.org/935033.
Hence, I am wondering, whether I should disable the use flag gstreamer as I am under the impression that GStreamer is only a reminisce of the past. However, I am also wondering what I would I if I did so. Currently, the following installed packages use gstreamer:
- app-office/libreoffice-7.6.7.2:0
- dev-qt/qtmultimedia-5.15.14:5/5.15
- media-libs/libcanberra-0.30-r7:0
- media-libs/opencv-4.8.1-r2:0/4.8.1
- media-video/pipewire-1.0.7:0/0.4
- media-video/vlc-3.0.20-r11:0/5-9
- net-misc/freerdp-3.4.0-r11:3
What functionality would I loose without GStreamer (if any)?
The packages - dev-qt/qtmultimedia
- media-video/pipewire
- media-video/vlc
- net-misc/freerdp
all have ffmpeg as a use flag as well. Hence, I assume those package would simply use FFMpeg if GStreamer wasn't available?
An interesting package seems to be app-office/libreoffice. It has the use flag gstreamer but nothing else which looks like an alternative. I read that Libre Office cannot embed video/audio into presentations without GStreamer support. Is that correct? |

I have gstreamer disabled globally. You have a couple of packages which I don't (libreoffice + freerdp) but suggests they will at least build without the flag.
As for ffmpeg only qtmultimedia returned | Code: | !!! The ebuild selected to satisfy "qtmultimedia" has unmet requirements.
- dev-qt/qtmultimedia-6.7.1-r1::gentoo USE="X alsa opengl pulseaudio qml vaapi vulkan -eglfs -ffmpeg -gstreamer -test -v4l" ABI_X86="(64)"
The following REQUIRED_USE flag constraints are unsatisfied:
any-of ( ffmpeg gstreamer ) vaapi? ( ffmpeg ) |

I always asked myself the same question as user of plasma 
mpv and ffmpeg works for everything until now, even wine-staging without gstreamer!

| My understanding is that within KDE phonon is supposed to do the job of gstreamer (but I think it is more limited). I run KDE and gstreamer USE flag is disabled for ages. |
