On Flame, in both 2.0 and on master, if I turn on HDR and then switch to video recording the HDR indicator remains on the screen, which seems like the wrong thing. It doesn't actually do anything for videos, does it?

The HDR mode option remains in the menu when in video mode too, but I'm not sure whether that should be considered a bug or not.

The situation is much worse on master than it is in 2.0 however:

1) Launch camera
2) Use settings menu to enable HDR
3) switch to video mode
4) start recording video
5) camera plays the start recording sound but does not display the recording timer. It allows me to touch-focus, but none of the buttons do anything.  If I kill the app, it does not work when I restart it (black viewfinder) an I have to reboot the phone.

I'm going to go out on a limb and mark this as a 2.1 blocker and a regression.

Needinfo Mike becasue he may be interested in investigating the Gecko issues that cause the camera to become unusable.

Needinfo Diego and Justin because one of them can probably stop this from happening by turning off HDR mode when we switch to video mode.

I just tried reproducing this on Flame/KK:
- gonk:  v162-3
- gecko: master:a7cf4142b4a5c50e95b6929de4141ca55b135d33
- gaia:  master:c97d1b6c3094e854377b6affa5f46b8d4b7316ce

...and although the HDR menu option is there in video mode, and it can be enabled (weird), video recording progresses normally.

I just tried to reproduce this on my dogfooding phone, which is loaded with:
- gonk:  v123
- gecko: master:20140808123011
- gaia:  master:88e0a972

...and didn't see the issue.

My phone is a bit of a Frankenstein's monster--I'll try flashing something a little more recent.

Update: using the STR in comment 0, I can reproduce this issue!

What I see is that recording starts fine. While recording, touch-to-focus brings up the focus circle and it spins, but it never turns green and the viewfinder never focuses where I touched. Also, I can stop recording, but once I do, none of the camera UI elements respond except touch-to-focus (which now happens everywhere), which still doesn't do anything.

Killing the Camera app and reopening it brings it back up with a black viewfinder.

Build, running on Flame/512 (to enable HDR):
- gonk:  v123
- gecko: b2g-inboudn:7048b5362ad0
- gaia:  master:1a6282f433f87031e62fe1bf0a79992e8d30ac17 + bug 1051200 patch
Further to comment 5:
- if HDR is off, the issue does not reproduce.
- if HDR is off when switching to video mode, and then enabled while in video mode, the issue does not reproduce.
Update to commen 6:
- if HDR is off when switching to video mode, and then enabled while in video mode, I can start recording, and stop it (like in comment 5); but when I start recording again, the issue does reproduce. Eventually I get a blank alert box:


...and after dismissing the alert box in comment 7, the viewfinder is black. The Camera appears to respond to touches-to-focus, though they never succeed; and tapping the start-recording button brings the alert box back.

This PR hides the HDR indicator while in video mode so it's not misleading for the user. 

I cannot reproduce the issues described in comment #6 and comment #0. Can you please try again to reproduce again in master? 

The HDR mode enabled should not affect video recording. If we still see those issues we should into the drivers and gecko land to understand what's going on.

Thanks for keeping me in the loop, Diego. Other than the HDR icon, I was never able to reproduce on master, only on 2.0, and I'm surprised that Mike was able to in comment 6.  I fear that this is something we need to fix in 2.0, if it still reproduces there.

I can't reproduce this on master (from Friday) or 2.0 (from today) anymore. On master, I did manage to get the phone into a state where the slider was on the video camera but the shutter button was for still photos, so I could toggle back and forth but could never take videos.  Probably a separate bug, but I'll attach my screenshot...

Please ignore comments #11 and #12. Looks like that was fixed in bug 1054963

The landed PR only hides the HDR indicator when switching to video mode.

I don't see the bad behaviour in comment 0 anymore with HDR on. But I do notice that HDR on does very much seem to affect video recording. Compared to normal (HDR off), a video recorded with HDR on is over-exposed and colours look washed out.

Since this has landed and the issue no longer appears, marking RESOLVED FIXED.
