I'm happy to take a look at this as this seems like a critical item for this package. Is there any starting point on this implementation? |
Take a look at my comment here: #1726 (comment). I would guess this is related to implementing the pre-capture sequence. |

Thanks to everyone who already sponsored towards this goal in the polar pool linked here - we're at $190 right now. $2,810 left to go 😅 As a teaser I just implemented very basic flash capture which uses an OS feature - classic Android; this does not work on every phone. It's a short torch burst which does not wait for AE/AF exposure to be settled. A proper implementation requires a fully custom precapture sequence that enables the torch, then waits for AE/AF to adjust, then lock AE/AF to that value, turn off the torch again, then capture with a single flash burst, and then turn the torch off again, and return to auto-AE/AF. This is quite complex, that's why this feature request is marked at $3,000. |
Implements a semi-working version of flash photo capture for Android. This isn't properly implemented because a proper implementation requires a fully custom precapture sequence that enables the torch, then waits for AE/AF to adjust, lock AE/AF, then capture with a single torch burst, and then turn the torch off again. This is quite complex, that's why the feature request #1890 is marked at $3,000. For now, this is a simple flash burst which _sometimes works_, _sometimes not_ - highly depends on the device. If anyone wants true working flash capture, sponsor in #1890.

Update: We're far off from the $3,000, but I decided to implement Flash anyways - PR is up, I'm testing everything now!!! 🥳🎉🚀 feat: Flash with AE Pre-capture trigger for Android (#2558) (check out the code changes, there's a ton of stuff required for this lol) |
|
I just released VisionCamera 3.9.0-beta.4, which contains flash support! (will continue testing more, then release 3.9.0 as stable) With that I'd say this feature request is now finished - thanks to everyone who donated to the money pool!!! ❤️ |

What feature or enhancement are you suggesting?
Flash (photo/video) or Torch currently does not work on Android because of the Camera2 rewrite. It's quite tricky to add flash capture, as the exposure has to be handled manually in Camera2.
What Platforms whould this feature/enhancement affect?
Android
$3,000
I will implement flash for $3,000. Donate to this polar pool to support this feature.
