SceneSwitcher on ARM (RPi4) about sceneswitcher HOT 32 CLOSED

You would have to compile the plugin for arm.
I am not aware of anyone having prebuilt arm binaries available for this plugin.
The x86 prebuilt binaries of the plugin won't be of use as they won't run on arm cpus.

If you built obs itself for arm already it should be as simple as adding the the plugin to the OBS tree, adding its directory to cmake and starting the build again.
(See "Compiling in tree")

Does this help you in any way?

from sceneswitcher.

I am unsure of how i could compile it for ARM, but I understand what you mean, indeed. Thanks for your answer.

from sceneswitcher.

Where did you get an arm version of obs-studio from?
Maybe a crosscompilation toolchain is available there and I could just build it for you. (Although I doubt it)

from sceneswitcher.

I doubt it too. I mainly followed instructions from this thread. Trying to compile it in tree results in several errors.

from sceneswitcher.

Can you share a log?
Maybe it will be easy to resolve.

from sceneswitcher.

Compiling in tree does not work, as intended, Compiling out of tree outputs this error file while trying to run "sudo make -j4". I might have done something wrong, but fyi, I can successfully run the cmake command.
Here is the content of obs-studio/UI/frontend-plugins/SceneSwitcher/build/CMakeFiles/CMakeOutput.log
I couldn't make a lot of sense of it, i hope it will be useful.

from sceneswitcher.

Some header files cannot be found in the first log.
Have you set all cmake variables correctly?
(But it could also be an issue with the cmake file - i have not tried building out of tree in a while)

What is the issue you are facing with building in tree, as you mentioned it is not working as intended?

from sceneswitcher.

What is the issue you are facing with building in tree, as you mentioned it is not working as intended?

Please correct me if i'm wrong, but by compiling in tree, following the instructions (downloading the code in the right folder, modifying CMakeLists.txt), I presuppose that the plugin should be working (I might be completely wrong). Though, when i start OBS Studio, it isn't recognized at all.
Also OBS doesn't seem to load anything related to the drontend-plugins folder.

Have you set all cmake variables correctly?

I think i set all the variables correctly, as the cmake command outputs no error. This is confusing.
Thanks for your time.

Ah, so it built without issues?
Can you find the corresponding *.so file for the plugin in your build folder?
But if not even the frontend tools are working I have my doubts that the plugin will work.

from sceneswitcher.

I did the entire compilation again, and I hit the same errors when executing "make -j4", and thus there are no so file anywhere in the build folder. Here is a tree of this folder:

Also, i can't tell if the frontend tools are working or not. What i can say however is that there is no output from them in the terminal when i run OBS.

from sceneswitcher.

Sorry, I am a bit confused.
The problem is once again that the header file obs-frontend-api.h cannot be found.
Are you compiling in tree or out of tree?

I see that you placed the SceneSwitcher sources in tree under /home/pi/obs-studio/UI/frontend-plugins/SceneSwitcher, but at the same time you created a build folder under /home/pi/obs-studio/UI/frontend-plugins/SceneSwitcher/build.

Can you try modifying /home/pi/obs-studio/UI/frontend-plugins/CMakeLists.txt and add the following line:
add_subdirectory(SceneSwitcher)

Then just switch to /home/pi/obs-studio/build and run "make -j4" there?

(Unless you tried that already of course :) )

That's already what I did, and I already sent the logs of this command above.

Are you compiling in tree or out of tree?

I am kinda clueless on which one I should do. Compiling in tree doesn't seem to do anything, and compiling out of tree results in errors when doing "make -j4".

I should probably download "obs-frontend-api.h" somewhere and see if it fixes anything?

Unless you are building a very old version of OBS this file should be part of the OBS sources.

from sceneswitcher.

The file always has been there, in the OBS sources.

Okay, my bad. I was helped by a friend with more knowledge in software dev. than me. To sum up, I didn't understood that compiling from tree meant that I had to rebuild OBS entierly. Thus, following the thread i sent earlier, that's what I did, and it succesfully compiled. I didn't test it yet, that's why i'm not closing the thread on this comment. I'll report the issues, if I find any.

Hi , tried to compile without success , sorry . DId you maybe had success and be so kind to share it please ?
Thanks a lot !!

from sceneswitcher.

Did you run into compilation issues or issues at runtime?
Could you share a log?

Unfortunately I do not have a setup on which to compile it on and I am not sure if corss-compiling would work.

Double checked and dirs

from sceneswitcher.

Judging by the log you sent above it looks like you seem to accidentally have set some cmake variables incorrectly.

Instead of running a single cmake command with all its parameters you seem to have ran some of the arguments as separate commands.
For example "-DLIBOBS_FRONTEND_API_LIB="/usr/lib/libobs-frontend-api.so.0.0"" should have been part of the cmake call but you have called it as a separate command, which does not work.

If you built OBS yourself I would recommend that you also add the Scene Switcher as part of that build.
This will save you the trouble of setting all the cmake variables.

(I have described this in a previous comment)

from sceneswitcher.

I see , well as i already told im not in compiling stuff so , if you will be son kind to explain me . I compliled OBS studio using the script mentioned here : https://obsproject.com/forum/threads/obs-raspberry-pi-build-instructions.115739/

from sceneswitcher.

Assuming that your obs-studio source code directory is located under /home/pi/obs-studio run the following commands:

cd
cd obs-studio/UI/frontend-plugins
git clone https://github.com/WarmUpTill/SceneSwitcher.git

Then edit the file /home/pi/obs-studio/UI/frontend-plugins/CMakeLists.txt and add the following line:
add_subdirectory(SceneSwitcher)

Finally run:

cd
cd obs-studio/build
make -j4
sudo make install

Let me know if you run into issues or have any questions.

Wait , recompiled Obs studio , re lauched with your instructions and scene switcher compiling finished successfully.
But i cannot find scene switcher under menu / tools
Cannot also find under /home/pi/.config/obs-studio/plugins and /usr/lib/obs-plugins

from sceneswitcher.

If compiling worked you should find the plugin's so-file using this command:

cd
find obs-studio/build -name advanced-scene-switcher.so

Does installing it manually help?
If it does not, can you share a log file of the OBS startup?

from sceneswitcher.

Hi , searched everywhere but advanced-scene-switcher.so is not there

Then I would assume that the compilation failed.
I am sorry but I can only guess what went wrong with the current logs.

from sceneswitcher.

Thanks for patience , you are very kind , you mean you need full logs ?

from sceneswitcher.

No problem.
I assume more logs could maybe help - I am just not sure what to look for yet.

But in general the previous log you shared with the linking issues ...
[ 58%] Linking CXX shared module linux-capture.so
c++: error: CMakeFiles/linux-capture.dir/linux-capture.c.o: No such file or directory
... seem very unusual.
I am not sure what would be causing such strange behavior.
Maybe it is due to the limited resources available on the PI4, but it is hard to say.

But let us maybe work this out in a conversation on the OBS website and report back here when we got it to work, just so we do not spam this thread with sharing build logs over and over.
So feel free to send me a PM there.

from sceneswitcher.

ok ! thanks

from sceneswitcher.

It looks like cleaning the build environment and installing all dependencies (libxss-dev) seemed to resolve the issues and plugin was built successfully for arm and can be loaded by OBS.
