Script to configure gstreamer for MATE Desktop

[igorzwx]

The original Temüjin's script is here: http://www.4front-tech.com/forum/viewto ... 324#p13516

To use gstreamer with OSS4 on Linux Mint 14 Mate, you may need to install some packages:

Code: Select all

$ sudo apt-get install gstreamer1.0-plugins-good gstreamer1.0-tools gstreamer0.10-plugins-good gstreamer0.10-tools
$ sudo apt-get install mate-conf gconf2

Gstreamer manual is here: http://gstreamer.freedesktop.org/data/d ... using.html

Magic script for MATE Desktop:

Code: Select all

#!/bin/bash
# Temüjin's script modified for MATE Desktop.
# Configures gstreamer for OSS4 if no GUI is available to do so. Assumes you have mate-conf, gconf2 and gstreamer0.10-tools packages installed.
# Change to the directory you saved this file to and:
# chmod +x oss4gstr.sh
# ./oss4gstr_mate.sh


PREFIX=''
if test "`gst-inspect-0.10 oss4 | grep oss4`"
then
   PREFIX='oss4'
else
   PREFIX='oss'

MIXER=$PREFIX'mixer'
SINK=$PREFIX'sink'

# The following commands will set value "codec3.jack.green.front" for default_mixer_tracks key:

mateconftool-2 --type string --set /desktop/mate/sound/default_mixer_tracks codec3.jack.green.front
gconftool-2 --type string --set /desktop/gnome/sound/default_mixer_tracks codec3.jack.green.front

# You can change "codec3.jack.green.front" to "vol", or "pcm",  or "vmix0-outvol", or else (it depends on your ossmix).

# Sound events will be disabled. If you need them, set event_sounds to true

mateconftool-2 --type string --set /desktop/mate/sound/default_mixer_device $MIXER

echo "New settings for GNOME/gstreamer:"
 gconftool --recursive-list /desktop/gnome/sound
 gconftool --recursive-list /system/gstreamer/0.10/default

# return 0

Make it executable, and run:

Code: Select all

$ ./oss4gstr_mate.sh

The output should be like this:

Code: Select all

$ ./oss4gstr_mate.sh

NOTE: You can also set the value of "default_mixer_tracks" to "vol", or "pcm", or "vmix0-outvol", or else (it depends on your ossmix).

On, Linux Mint 14 Mate, "default_mixer_tracks" and "default_mixer_device" seem to be "deprecated". They can be set to arbitrary values. It does not change everything.

On a notebook, special multimedia keys may work, or may not work (this is usually the case).
If they do not work, you may try to fix them yourself:

mate-settings-daemon-gstreamer is patched to support notification with multimedia keys.
It works, but it seems to be extremely buggy, especially with Intel HDA codecs.
It is usable with old AC'97 codecs.
For Intel HDA codecs, you may prefer "custom keys" without notification.

Custom hotkeys (example):

Code: Select all

$ mate-keybinding-properties

$ ossmix vol +2
$ ossmix -- vol -2
$ ossmix vol 0:0

Instead of "vol", you can use "pcm", or "codec3.jack.green.front", or "vmix0-outvol", or else (it depends on your ossmix).

Code: Select all

$ ossmix codec3.jack.green.front +2
$ ossmix -- codec3.jack.green.front -2
$ ossmix codec3.jack.green.front-mute TOGGLE
