Add ability to use camera flashlight as a lightsource when filming video in dark environments.

(This answer is transferred to wiki post in order to prevent getting karma from it. However if you like the idea, please give your vote.)


Edit:

Finally the latest Sailfish OS 2.0.2.51 Aurajoki release supports this feature. :)

Nicr idea, like it worked with N9. Have you tried to use Flashlight app to turn on the led and then recording the video?

Not yet but I'll give it a try! Edit: Apparently I find it is not possible to use both simultaneously, since flashlight app works only when it is active app and leaving the app will shut down the light.

Yep this would be very helpfull

For me, this option was not in the last update (Aurojoki) and is also not in the new EA update (Fiskarsinjoki). Not that I do much videoing of a night time, but it could be very handy.

@Markkyboy Maybe the new camera package got missing on the update - try to execute version --dup in the terminal to install missing/not updated packages. :)

Or you just don't see the option in the camera app? You have to open camera, pull down the options menu and activate the video mode, then in video mode again pull down the options menu and right next to the option to switch between picture/video mode there is the option to manually turn on the flashlight.

Is the light even made for this? I remember in other phones they were breaking since they were initially made to be running only a short amount of time. Using the light as lamp could kill it very fast. Does anybody know if this is an issue here?

Well after a couple of minutes the back of the phone (where the flash LED is) gets quite warm. Nothing where I would say critical but this is indeed a good hint. I personally would like to use it for some camera based measurements/metrology. There I only need the the LED on continuous for maybe 30s...

It should be fine, it's only an led and they have a very long lifetime.

I think it is not the question of general lifetime but rather how hot the led can become. I mean there is a lot of sensitive electronics nearby, so eventually this might break the phone even if the led still works... :)

The app cameraplus in OpenRepo/Warehouse is able to do that

Cheers Mika
