# build obs from source
|
|
Install:
|
|
```
|
|
linux-headers (I have linux61-headers-6.1.60-1)
|
|
v4l2loopback-dkms (v4l2loopback-dkms-0.12.7-2 for me)
|
|
ninja cmake curl ccache zsh qrcodegencpp-cmake hiredis pkgconf libdatachannel libjuice rav1e-git dav1d-git decklink
|
|
```
|
|
Download and unpack CEF (for browse source) + clone and build obs in portable mode:
|
|
|
|
```
|
|
clear && cd "$HOME" && rm -rf "$HOME/portable_obs_build_dir" && mkdir -p "$HOME/portable_obs_build_dir/" && cd "$HOME/portable_obs_build_dir" && wget https://cdn-fastly.obsproject.com/downloads/cef_binary_5060_linux64.tar.bz2 && tar -xjf ./cef_binary_5060_linux64.tar.bz2 && git clone https://github.com/obsproject/obs-studio --recursive && cd obs-studio && rm -rf build && rm -rf "$HOME/.config/obs-studio" && rm -rf "$HOME/portable_obs_build_dir/release" && mkdir build && cd build && cmake -DLINUX_PORTABLE=ON -DCMAKE_INSTALL_PREFIX="$HOME/portable_obs_build_dir/release/" -DENABLE_BROWSER=ON -DCEF_ROOT_DIR="../../cef_binary_5060_linux64" -DENABLE_AJA=ON -DTWITCH_HASH=0 -DTWITCH_CLIENTID=selj7uigdty0j5ijt41glcce29ehb4 -DOAUTH_BASE_URL=https://auth.obsproject.com/ -DENABLE_BROWSER_PANELS=ON -DENABLE_DECKLINK=ON -DENABLE_FREETYPE=ON -DENABLE_HEVC=ON -DENABLE_JACK=ON -DENABLE_LIBFDK=ON -DENABLE_NEW_MPEGTS_OUTPUT=ON -DENABLE_PIPEWIRE=ON -DENABLE_PLUGINS=ON -DENABLE_PULSEAUDIO=ON -DENABLE_QSV11=ON -DENABLE_RNNOISE=ON -DENABLE_SCRIPTING=ON -DENABLE_SCRIPTING_LUA=ON -DENABLE_SCRIPTING_PYTHON=ON -DENABLE_SERVICE_UPDATES=ON -DENABLE_SNDIO=ON -DENABLE_SPEEXDSP=ON -DENABLE_UI=ON -DENABLE_V4L2=ON -DENABLE_VLC=ON -DENABLE_VST=ON -DENABLE_WAYLAND=ON -DENABLE_VST_BUNDLED_HEADERS=ON -DENABLE_WEBRTC=ON -DENABLE_WEBSOCKET=ON -DBUILD_TESTS:BOOL="1" -DENABLE_JACK:BOOL="1" -DENABLE_SNDIO:BOOL="1" -DENABLE_RTMPS:STRING="ON" -DCMAKE_BUILD_TYPE:STRING="RelWithDebugInfo" -DCALM_DEPRECATION:BOOL="1" -DENABLE_LIBFDK:BOOL="1" -DENABLE_UDEV=ON .. && make -j12 && make install && cd "$HOME/portable_obs_build_dir/release/bin/64bit/" && ./obs
|
|
```
|
|
|
|
Remove libva-vdpau-driver (segfaults obs on load don't know why):
|
|
```sudo pamac remove libva-vdpau-driver```
|
|
|
|
In the end rav1e-git and dav1d-git will probably complain about ffmpeg depending on them, but all three work just fine.
|
|
I've used a combination of pacman, pamac and pamac GUI to install all the needed things, cause none seect one would onlieg and do what I wanted it to do.

# Get back the ability to free webcams/capture cards when not in active use
|
|
|
|
As of 4th of December 2023 OBS on Linux (v 30.0!!!) still has no way to disable v4l2 devices when those are not in active use. <br>
|
|
The most baffling thing is that the patch was made by [julijane](https://github.com/obsproject/obs-studio/pull/3159/files) almost ***four years ago***.
|
|
Insane, right?
|
|
|
|
Anyway, this patch is for OBS 30.0 (more specifically the master branch) and all it does is gets in Julijane's changes.
|
|
Clone OBS, apply the [patch](files/Add%20deactivate%20button%20to%20v4l2%20devices%20--%20pr%233159%20--%20patch%20for%20OBS%2030.0%20with%20changes%20from%202020%20by%20julijane.patch)
|
|
via git and build. Onec done, you'll have that sweet "Disable when not showing" checkbox you love so much back.
|
|
|
|
In case you have no idea how to apply patches:
|
|
|
|
```
|
|
# Switch to the branch where the changes should be applied
|
|
$ git checkout master
|
|
|
|
# Apply the patch
|
|
$ git am bugfix.patch
|
|
|
|
# Check what has happened in the commit log
|
|
$ git log
|
|
```
|

# remove flatpak support
|
|
removing flatpaks from manjaro be like:
|
|
|
|
`$ flatpak list`
|
|
|
|
Remove a named app
|
|
`$ flatpak uninstall io.lbry.lbry-app`
|
|
|
|
Uninstall unused flatpaks
|
|
`$ flatpak uninstall --unused`
|
|
|
|
Uninstalling apps may not remove everything - so how much is left?
|
|
`du -ch /var/lib/flatpak`
|
|
|
|
If the total is more than a few MB you may want to cleanup leftovers
|
|
`sudo flatpak repair`
|
|
|
|
Disable flatpak support
|
|
`$ sudo nano /etc/pamac.conf`
|
|
|
|
Modify the last lines to look like below and save the changes (you will also find snap support) but as this is about flatpak leave as is.
|
|
```#CheckFlatpakUpdates
|
|
#EnableFlatpak
|
|
```
|
|
|
|
Then remove flatpak packages using pacman
|
|
`$ sudo pacman -Rns flatpak libpamac-flatpak-plugin`
|
|
|
|
Then update your system
|
|
`$ sudo pacman -Syu`
|
|
|
|
Finally restart your system

create the folder ~./cargo and use sudo on whichever command you're trying to issue.

install that shit if you have nvidia LOGO on your GPU.
|

Else hope that OpenRGB works.

# No object for D-Bus interface

|
|
|
NTFS partitions can be that way even with no errors on them
|
|
|
|
`systemctl --user restart gvfs-udisks2-volume-monitor`
|
|
|
|
Also,
|
|
- First, go to Dash (for Ubuntu) or run gparted using superuser, preferrably gparted-pkexec.
|
|
- Right click the partition, choose New UUID.
|
|
- Click the Apply button.
|
|
|
|
Update: Some people claimed that just by having gparted refreshing information, the problems are solved. You should try that first, as refreshing UUID screws up fstab.

# no scrollbar buttons anywhere!
|
|
fnid your theme in usr/share/themes and search for something like this in main.rc or main.css:
|
|
|
|
```
|
|
GtkScrollbar::has-backward-stepper = 1 (change value from 0 to 1)
|
|
GtkScrollbar::has-forward-stepper = 1 (change value from 0 to 1)
|
|
```
|
|
|
|
If you encounter any imports from a resource:// schema, go there in Thunar and search for "stepper" to know what to add.
|
|
|
|
On gtk2 it looks like described above.
|
|
On gtk3 it looks like this:
|
|
|
|
```
|
|
* { -GtkScrollbar-has-backward-stepper: true; -GtkScrollbar-has-forward-stepper: true; }
|
|
```
|
|

Experiments are your friends now.
