Description

Before a suspend/resume, launching this command takes ~1 second: gst-launch-0.10 v4l2src ! xvimagesink

After a suspend/resume, launching the same command takes ~8+ seconds. Interestingly, the camera led turns on right away.

Same slow launch with gst-launch-0.10 v4l2src ! ximagesink suggesting that xv isn't the culprit. Also ran xvtest before/after suspend/resume and it ran at the same speed. Looks like xv might be off the hook.

I am not sure where the slow down is taking place, but it give the impression that the Record activity is broken after a suspend/resume. Any thoughts were the problem might lie?

Confirm in update 1 build 695, on G1G1 hardware.

In the record activity, starting a video record normally takes 1-2 seconds, but it takes 10-12 seconds AFTER a suspend/resume. It does not matter whether the record activity is active during the suspend/resume cycle.

(I didn't test the command line app mentioned in the original post.)
