JP1 Remotes

The .amsr files themselves are just JSON-formatted data structures. Paste that content into http://jsonlint.com to view it nicely formatted.

As for the actual code, it's frequency followed by array of pulses - one of the simplest methods of representing a raw IR code.
Excepting for the frequency ...

Here you go:

{"name":"tivo-myshows0","all_codes":[{"function":"BUTTON NAME","code1":"36044,32,32,64,32,32,64,64,64,64,32,32,64,64,64,64,64,32,3236,"}]}

On that page you have to enter the [BUTTON NAME] followed by the pronto code. Entering just the code generates commands missing the first pair in ...

can you provide that .amsr file ?

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 ...

Unfortunately I'd have to open up the phone / tablet to see the chip, and I'd like to postpone that for a bit (warranty issues). I DO know it's a msm8974 chipset though in the G2.
Also, the bitrate is 19200 baud, or at least that's the frequency with which the preinstalled Quick Remote app writes ...

One more update:
Changing ANY of the bytes renders the code useless. The 10% tolerance rule doesn't apply here, if you change any of the numbers by even just 1, then it stops working.

This makes me think there are two things that may be happening here:
1. this code might have some kind of error ...

As far as I can tell it has an UEI chip inside, and yes, it's very possible that it is encrypted. Biggest tell is that the same code recorded/learned twice results in codes with pieces that are very different.
Here they are (the Vol UP recorded from a Samsung TV):

64,65,66,67,0,55,16,0,25,16,1,-79 ...

Thank you Barf! I've also tried the same thing, but doing the conversion by simply adding 127 (and even 128) to each value.

I just found out that the same thing happens with the preloaded Quick Remote app on the LG G2. Unfortunately, just as with the Vizio, there's no way of extracting the codes, or even having a simple look at them. To get those codes I had to do quite a bit of "hacking".

Either way, I'm sorry for not ...

it's a signal sent by the preinstalled app on the Vizio Tablet. That app, and the hardware on that tablet were built by UEI, and all the access they give to us, the developers, is to use their own database of codes, which often lacks support for devices. I want to be able to use my own codes, which ...

Hi guys!

I've been stalking this forum for a while trying to find an answer to my problem, without any luck. I have a few codes in some strange format I haven't seen before, which I'm trying to figure out. The purpose here is to understand this format so that eventually I can convert codes from JP1 ...
