The previous crash is on manta

[Daniel (ichbrauchspeicher)]

I got a very similar issue with the mediaplayer app on my maguro. If you open e.g. the "Tears of Steel" movie and if you jump very fast between different scences then the movie freezes and you also get a picture which is mirrored and which has corruped edges. So maybe this problem is not really related to the camera app.

[Günter Schwann (schwann)]

I guess the camera is set to be ready too early. It's done before the first actual preview frame is available.

[Günter Schwann (schwann)]

The manta crash is another issue (releaseRecordinFrame() is called, but should not - fix in libhybris is on it's way)

[Günter Schwann (schwann)]

@Daniel, that is another known issue. There is a bug report for that (sorry can't find it).
