Hey @Kano3D,
I had a little free time over the holidays and created a simple youtube sbs player app.
Steps :
Install the apk
Open youtube app and navigate to the sbs video.
Pause the video and click share, Leia Youtube Clone app should be present in the app chooser dialog. Click it.
Wait for a few seconds for the video to load in the app.
This works only for sbs videos.
