Setup

Because of licensing, I'm not allowed to include some of the NDI SDK components inside this repository, so you'll have to source it yourself!

0. Install Dart/Flutter and LLVM
1. Download the NDI Advanced SDK (for Android)

• Note: Only the NDI Advanced SDK is available for Android

2. Add the library files into their respective android/src/main/jniLibs/<architecture> directory
   • See Expected Structure below
3. Remove union references in lib/ndi/includes/Processing.NDI.structs.h
4. dart run ffigen

Expected Structure

\---jniLibs
    +---arm64-v8a
    |       libndi.so
    |       libndi_bonjour_license.txt
    |       libndi_licenses.txt
    |
    +---armeabi-v7a
    |       libndi.so
    |       libndi_bonjour_license.txt

flutter_ndi's Issues

Undefined class NativeLibrary, can't understand how this should work

Hello,
I would really like to use this but there are a lot of holes in the documentation on the way to use it :)

• Is this repo a full project that can run as standalone (after ffigen) or is it just the lib generation ?
• If it's not the full project, what action is needed after ffigen, which files to copy to my actual project ?
• It seems that NativeLibrary is not (or not anymore) a defined class in FFI, I couldn't understand how to be able to use it. Is this a version problem or am I missing something ?

Thank you very much

NDI Sender functions ?

Hello,
I'm looking to send NDI, not receive, and it seems that your plugin has a focus on receiving, there is only one function for sending.
Is there any way / example / hints to do that ?

Thank you !

NDI Sending crash

After spending some time fiddling around, I finally got something to half work (the received texture on the PC side is weird as f* but something's passing through !)
I get a crash just after frames are received in the NDI Studio monitor. If nobody is actually receiving frames, it seems ok

Anyway, if you manage to get a sample sender working that would be AWESOME !!

Cheers
