What's a PlayOnly?

There is a “playonly_aware” attribute that can be manifested:

What is Play Only button and where can i encounter it?

PlayOnly refers to the Play button on a remote which has separate buttons for Play and Pause. I don’t believe that any Roku products have such a remote, but the situation can arise when using a TV’s native remote with the MHL stick.

Aha!
So if playonly_aware is manifested, then the app on use of standalone “Play” button via CEC will receive roUniversalControlEvent with code^ different than 13 (the usual Play/Pause) ? And maybe the same is for the standalone Stop button?

(^) shot in the dark: maybe these codes are 11 and 12

11 is Backspace, dunno about 12

The PlayOnly code is 22. If playonly_aware is not set, this is remapped to 13.

What is “Backspace”?
Remote’s “Back” button is 0.

used for virtual keyboard entry, like backspace key on keyboard (I assume). I can’t remember where I found that out - I only ever used it as a meaningless entry to stave off the screensaver!

Oh, you meant ECP? Genius! Here, i collected some codes:

/keypress/Backspace     = 11
/keypress/Search        = 12
/keypress/Play          = 13 'also PlayOnly by default
/keypress/Enter         = 15
/keypress/PlayOnly      = 22 'when `playonly_aware` manifested
/keypress/Stop          = 23
/keypress/VolumeUp      = 24
/keypress/VolumeDown    = 25
/keypress/VolumeMute    = 1114113   '0x110001
/keypress/ChannelUp     = 1114134
/keypress/ChannelDown   = 1114135
/keypress/Sleep         = 1114138
/keypress/Game          = 1114139

Btw @RokuMarkn - while exercising above, seems somehow i wedged the player into a bizarre state, in which the Home button won’t work (by physical remote or ECP), while all the other remotes did work. Ultimately i had to power-cycle it.

Just a note… PlayOnly is “documented” in bslCore.brs:

BUTTON_PLAY_ONLY_PRESSED : 22

Some of the other buttons are not intended for app use, and aren’t documented there.
