Playing large video files in Gear VR in Unity project

[RGB3D-Robert]

I'm creating a Gear VR android app that plays a large 30 minute video. I have read that I should not use the StreamingAssets folder, but I don't see any information about what I should be using instead. If I put the video in Assets/videos it is not included in the android build. Should I be using the resources folder or is there another way to include the video? (My project is also on iOS, but I'm currently not having any problems on that platform.) I have read that the PersistentDataPath folder can be used, but I don't know how to get my video into that folder when from unity. I don't want to copy the video there and have two 600mb files when only one is used.

Gear VR supports 1 expansion file, up to 4GB. We have some documentation in the works on it. For now, this page will get you started: https://docs.unity3d.com/Manual/android-OBBsupport.html

You have to adhere to androids naming convention of:

main.<version>.<package>.obb

So for example, if your app package name is com.sample.app and this is V1 of your app, the extension file would be

main.1.com.sample.app.obb

You can't upload the extension files with the web interface, you'll have to use the command line tools from here https://developer.oculus.com/blog/faster-build-uploads-with-cli/

The command to upload will look something like this:

ovr-platform-util upload-gear-build --app_id <app id> --app_secret <secret> --apk <apk path> --obb <external data file path> --channel alpha --notes "Uploading apk and external data"

Hi @oculus_gabor
How could we create an obb bigger than 2 GB with Unity? Thanks!

That's a question for Unity. Bit of a black box.

Thanks for your response @oculus_gabor , but we think that it could be related with Unity (of course), but also and perhaps more important, with Android and its APK Expansion Extension File System.
We have openend a thread here: https://forums.oculusvr.com/developer/discussion/60070/big-up-to-4gb-expansion-file-support-how.
Please, could you help us with that? Many thanks!
