Bug ID: 767645
Summary: Unallocated memory access in OpenGlSurfacePainter
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: minor
Priority: Normal
Component: qt-gstreamer

quick fix
The Qt application on our custom embedded platform (imx6, analogue camera input
- format I420) kept crashing about 50% of the time when no camera was attached.
After investigation I found that only 518400 was allocated, instead of the
622080 assumed. When the camera is connected, it does indeed allocate 622080.
As I am not an expert in hardware or GStreamer, I don't know if the error is in
the video driver or that indeed it is a bug that no size is given with the data
pointer.
See the patch for the solution that worked for us.
