FFmpegInteropX in Unity (UWP / ARM64) #374

Closed slice3984 closed 1 year ago

slice3984 commented 1 year ago

Hello, i try to get this package to work in a Unity UWP app, in my case I work on a HoloLens2 application which is supposed to use this library to decode incoming H264/5 encoded frames.

I struggle to get this to work for a couple of days now and hope I could get help here, I'm not too familiar about how to get external packages / libs to work in Unity.

My first approach to get it working was to just use the plugin NuGetForUnity, but this already failed attempting to install the FFmpegInteropX.FFmpegUWP package with the following error:

Can't find a matching dependency for the NuGet Package FFmpegInteropX.FFmpegUWP 5.1.100 that has a TargetFramework supported by the current Unity Scripting Backend. The NuGet Package supports the following TargetFramework's uap10.0

My second attempt was to compile the FFmpeg libraries FFmpegInteropX Build Instructions and copying the compiled libs over to my Assets > FFmpegUWP > ARM64 folder.

After this I edited the settings of each dll to target UWP with ARM64.

Then I extracted the FFmpegInteropX package and copied over the FFmpegInteropX.winmd and FFmpegInteropX.dll to Assets > Plugins.

Here I modified the dll and configured it as UWP / ARM64 and checking the "Editor" checkbox. I modified the .WINMD file to use UWP and checked the Editor checkbox in here as well.

After all of this I tried to import FFmpegInteropX into my unity script with a using directive but IntelliSense is unable to find the namespace.

I am no expert in Unity but i know some people have manged to use this with both unity and hololens. So it's possible. Just don't know exactly how. Maybe stackoverflow is a better place to ask.

Yea, I've seen some issues in here already mentioned my case and managed to get it to work and got hope someone in here could help me to set it up.

I also cannot help with this. I never used Unity and I don't have a Hololens.

There is a stackoverflow question about this: https://stackoverflow.com/questions/58394152/unity-uwp-how-to-import-dll-nuget-package-references-to-my-project

Otherwise, you could try to ping some of the people from the old issues in this repo. Maybe someone is able to help you.

Thanks for the effort, I think I will try my luck on stackoverflow.
