How to make a torch with strobe using camera flash? (Harmattan)

[deviouscode]

Hello.

I'm writing a small application for Meego Harmattan using Qt. And I have a couple of questions (yes, I've checked all related topics and still didn't find the solution):

1. How to use phone camera LED as a torch (Meego API+Qt or Qt Mobility)?

2. How to use phone camera LED/flash for strobe effect (Meego API+Qt or Qt Mobility)? Flash should blink when user tap on screen, for example.

I read that there is a V4L2 based solution but I still can't find it.

Any help is appreciated! Thank you!

I guess it will be great to have a wiki article about torch usage. I'll do it as soon as I'll find the suitable solution.

Qt Mobility camera backend is based on GStreamer and FlashTorch mode is not available I guess. But there are some Torch apps on the market that work! Could anyone advise on that? There is no solution even on meego.com

Sure, it is! Looking forward to seeing your article.
