I don't think there are any changes going into the app side in 2.2/master that causes this issue. Russ please do the initial investigation. If it is not the app issue, lets move it Audio/Video component to get the right set of folks looking into this.

Blocking Reason: Broken basic functionality

I don't see any change to the gallery app code that generates the poster image for videos since as far back as 1.4. However, I could not reproduce the problem with 1.4 and 2.0 (build ID 20141016183911). I can reproduce with 2.2 (build ID 20150105010205).

Requesting regression window.

In latest Flame 2.2 build this issue does not reproduce. Both video preview thumbnail and image in camera appear correctly, as well as video thumbnails in gallery app. It is possible that bug 1101230 fixed this issue as the prior testing for this issue was conducted on builds created before the commit.

The newly created video is showing proper thumbnail on my v2.2 flame, but old video clips(also recorded from flame with master a week ago, before branch) are still showing black.

Hi Shine, Could you try to check if this is a factor, also the location of storage(Settings -> Media Storage-> Default Media Location), open a new bug or reopen this if needed.
Thank you.

Hi Eric,
As you said, in Gallery app, the old video clips are still showing black. Do we need to reopen this bug?

When set the "Default Media Location" to “SD card” and “Internal”, this problem can't be repro on latest build of Flame2.2.

We can clone this, but just want to clarify first, new video are fine, old video are black, and after setting "Default Media Location" to either "SD" or "Internal", we cannot reproduce this issue? Is my understanding correct?

Hi Eric,
Your understanding is right.

Looks like the files themselves have something weird that makes this happen, not the app. I can reproduce that only with those 2 videos(which are taken by flame-kk master 0106)
