[App] libLockTV B/C/D/E/F/H - Parental Lock

[tempinbox]

Tested on c series arm T-valdeuc fw.
Works well, as expected with args too!!!!!
Thanks
i hope this was first of many uni-patch.

Great, thanks for report. I don't promise "many" patches because developing for C is quite boring, but it surely won't be the last one

Ok, I managed to find time to play with this lib as well, and it's awesome! The kids won't know what hit them

Now, I have a few questions/observations...
1. Once you unlock the pin code you can't "rearm" it by reinjecting the lib. It would be nice to have a mechanism to re-enable the pin-code on demand so that it can be locked/unlocked programmatically.
2. Once the channels are locked is there any way to remove the pin-code restriction programmatically? Meaning - the screen shows the "Input pin code" prompt, but if you disable the pin lock one of two things could happen:
2.1 The enter pin "dialog" automatically dissapears allowing the viewer to view unrestricted
2.2 The dialog remains, but accepts any pin as input and does a fake unlock (or dissapers altogether) on any keypress (e.g. CH+/CH-).
3. Possibly a slight bug - If I keep pressing CH+/CH- or change Source when the Enter ping code dialog is shown, I still can't see any content (yay!), but I can't enter data in the pin code dialog. When I start typing a digit the dialog resets back to blank and I can't finish inputting anything. I doubt that this is a bug you can fix, so don't worry about it - I just wanted to let you know.

Now, about the first two points - I'm not completely crazy, but here's my use case. Have cron turn off TV access at a specific time and turn access back on at a different time. The on/off time can be pretty close - e.g. in a 30 min interval, so that the little one can only watch a specific show on TV. But to do this, I'd need to be able to turn the pin code off on demand. Can you help out?

Also, a related question - is there any way to programmatically change the actual pin code? I figure it won't take long for the kids to brute force 4 digits... )

Too many questions kill questions

Actually I'm not really willing to come back to that lib I already did reluctantly

Quickly:
1) In state no, because it's resident lib and it can't be reinjected
2) Same as 1, in state no intended "interactivity".
3) Yeah, because I count keypresses and I expect a multiple of 4 !! (some dirty kludge to make lib compatible from B to H).
No number) Anyway your kids already know Mute>8>2>4>Power to reset pincode

As you might have noticed, I'm new around here so my questions will mostly sound silly/stupid/misinformed, but... as far as I've noticed, there are two types of libs - resident and "transient" or one time use? Why is this lib resident? So that you can enforce the pin-code input and check results/disable pin-code later? Once its done its job, can't the code just "exit"? I admit I have only a rough idea of how library injection works, but it's something I'd like to learn more of.

Otherwise the brute-force approach for what I want would be to reset the tv (thanks to you I know how) when I want to disable pin-code. I wonder if I can find out if the pin-code dialog is shown onscreen or if its unlocked... The log says "[LockTV] Right pin entered, unlocking TV!", so I could look for that at least...

I didn't know about that key combination... Hmmm, but if they resort to that they blow their cover - still not knowing the old pin to set it again, and I would know...

It's generally admitted there are "resident" and "non-resident" ones, but I'm not a good teacher
All depends if you want "one-shot" or "survey" stuff. And no it's not possible to "exit" from a resident lib (I'm not the author of samyGOso and I understand half of it...). Anyway there are always possible workarounds, just that any improvement to that lib is not on my agenda.

You can launch lib on startup, then remotely reboot TV when you want pincode to be prompted again (for example...)
