That is actually exactly what I'm doing. I couldn't disassemble the apps on the Vizio, but I managed to do that on the LG. Even more, I disassembled, added a lot of logging functionality (which is how I got to see the codes that they're sending), and put it back.
The LG has the QuickSet Services SDK preinstalled (which I modified), and the QuickRemote app works through it. The QuickSet SDK sends the actual signal to a serial port, (a character device in /dev ), which is handled by the driver. I'm guessing the IR driver there does some more processing, and I have yet to find the binary of the driver that manages the serial port so I can disassemble that one.

The Vizio VTAB1008 has an IrDA port(CNET review) so that is probably the way the App is sending out the IR signal. It doesn't look like there is a separate UEI chip.

FYI: Android 4.4 Kit Kat has an IR API.

Hey, is there any new info about this? Im also trying to convered learned UEI (LG G4) codes to either RAW/Pronto or something universal.

By looking at the SDK implementation of how this Code is sent, i cannot find a "pattern" as you said it seems that the driver does something more to it
