946375 - [Camera][emulator] Unable to capture photos and videos on emulator

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Camera, defect)

Description

[Dave Hunt [:davehunt] [he/him] ⌚BST]

When running the emulator builds from https://pvtbuilds.mozilla.org/pub/mozilla.org/b2g/tinderbox-builds/mozilla-central-emulator-jb I am unable to capture any photos or videos.

Steps to reproduce:
1. Download emulator.tar.gz from https://pvtbuilds.mozilla.org/pub/mozilla.org/b2g/tinderbox-builds/mozilla-central-emulator-jb and extract the contents.
2. Remove the line -camera-back webcam0 from run-emulator.sh (this doesn't work for me in VMWare, and removing this gives me an animation in the camera app).
3. Run ./run-emulator.sh
4. Launch the Camera app and attempt to take a photo or video

Expected:
Photo or video should be captured, and appear in the filmstrip at the top of the app and available via the Gallery and Video apps.

Actual:
When taking a photo nothing appears to happen and the Camera app becomes unresponsive. When taking a video a modal dialog appears stating "Video not recorded. An error prevented Camera from recording the video."

I was using https://pvtbuilds.mozilla.org/pub/mozilla.org/b2g/tinderbox-builds/mozilla-central-emulator-jb/20131204055447/

It is possible to make the emulator use existing camera hardware (e.g. the USB cameras build into laptops) and to present a viewfinder and take pictures, although the emulator is not fast enough to support recording.

In short: the emulator supports taking pictures (either a built-in fake one, or using a real USB webcam), but does not support recording videos.
