Well, I have dug up my EVO 3D device and decided to see what I needed to do to stream 3D contents from Plex to the phone via WiFi.
And I say, I have success.
I no longer need to place any movies on the SD card to watch. I just link to Plex via my app to watch.
I have done 3 videos so far of different types as source to mp4 as outputs.
Now the issue I have is that the phone is 4.0.3 android. The app installed is Plex Pass. I no longer have plex pass but the app is still working.
Also Plex app now needs 4.1 and up. So that brings in a issue with version of app you need to place on the phone if you do not have the app.
So I need to either find an app around the age of the plex pass I have or save the apk so just in case the apk goes belly up.
So if you want the settings, I can supply it. I'm using an older Handbrake. I will check later using the latest handbrake to see I can port the settings.
