Is it possible to use on Linux?

[philss]

Hi! Thank you for this project!

I want to stream programming sessions from my Ubuntu Linux 18.10, and I couldn't find instructions for how to build and install this plugin.
Is it possible to run on Linux?

PS: I already using on MacOS, but I wanna try on Linux.

I tried and I couldn't make it work. Perhaps it's possible with some different compilation flags, but I gave up with OBS IOS Camera, and I could make work with other tools explained in this blog post: https://steemit.com/technology/@tech.ninja/tech-quickie-convert-your-ipad-iphone-into-a-good-wireless-webcam-in-linux

Hey @philss, I saw you made this issue a while ago. I was able to get this plugin to compile on Ubuntu 18.04 by adding a few #includes in various places where I was seeing errors. I also had a problem at final link time because all of the libraries needed to be compiled with -fPIC. It seems to work! I ran into a quirk where sometimes I have to change between the front-facing and rear-facing camera in order to get the streaming to start working, but for the most part it seems to work okay with OBS 23.2.1.

Here is the commit to my branch that makes it work. The commit message has some compilation instructions. dougg3@2b6ed18

After doing this, I manually created the directory structure for the plugin and put it in ~/.config/obs-studio/plugins:

obs-ios-camera-source/
obs-ios-camera-source/data
obs-ios-camera-source/data/locale
obs-ios-camera-source/data/locale/en-US.ini
obs-ios-camera-source/bin
obs-ios-camera-source/bin/64bit
obs-ios-camera-source/bin/64bit/obs-ios-camera-source.so

EDIT 7/12/2020: I tried to put all the relevant information into a single location and help with branch confusion. My fork's master branch now contains the linux support changes, along with compilation/installation instructions in the README: https://github.com/dougg3/obs-ios-camera-source

@wtsnz I'm not sure if these changes break the Mac OS X or Windows builds, or else I might be a little more confident about cleaning up the build process and trying to get it merged with your main project, if you're interested in supporting Linux at all. I also realize it could be a pain if you try to officially support Linux and a bunch of people run into problems...

This worked great for me on Ubuntu 18.04. I had to also install libobs-dev so FindLibObs.cmake had the right pkg-config setup in place. I was also missing libavcodec-dev, but once those were installed the commit referenced above worked great. I'm not that familiar with OBS yet, but my plugin directory was /usr/lib/x86_64-linux-gnu/obs-plugins.

@dougg3 @bkylerussell
Just tried to build on Ubuntu 19.10 from the commit instructions and got a bunch of CMake errors. Any ideas?

CMake Error at CMakeLists.txt:321 (target_compile_options):
  Cannot specify compile options for target "mbedcrypto" which is not built
  by this project.


CMake Error at CMakeLists.txt:322 (set_target_properties):

Hey @jbberinger, I don't think you checked out my branch -- make sure you do "git checkout linux-support" after cloning

[jbberinger]

@dougg3 Thanks, that was the problem! I'm a little confused about the final step where you created the directories, and where you got the .ini and .so files?

[dougg3]

You should be able to find those two files somewhere inside the build directory you created while following the build directions -- then all you need to do is arrange them in the directory structure indicated in my instructions and run OBS :-)

[philss]

Awesome, @dougg3! Thank you! ❤️
I will give a try someday.

While OBS, as packaged for ubuntu, will have its plugins in /usr/lib/x86_64-linux-gnu/obs-plugins, it will still read your custom plugins from ~/.config/obs-studio/plugins, so you can put the plugin there (in ~/.config/...) along with its locale en-US.ini-file, as @dougg3 stated. That way, it will be loaded by OBS and it will be properly labeled as "iOS Camera" instead of OBSIOSCamera.Title

Just a heads up for future people who are trying to build the Linux version, I rearranged things a bit to help streamline the Linux build process and put all the relevant documentation in a single place. My fork's master branch now has the Linux fixes, along with an updated README.md with build/install instructions:
