CPU memory allocation error when trying to map a frame buffer

Submitted by Jeremi Wójcicki

Link to original bug (#784658)

Description

On ANDROID

In a pipeline:

videotestsrc ! video/x-raw,format=RGB,width=1280,height=720,framerate=30/1,pixel-aspect-ratio=1/1 ! glupload ! appsink

When trying to map a video frame in an appsink callback:

gst_video_frame_map(&frame, &info, buffer, (GstMapFlags) (GST_MAP_READ | (GST_MAP_FLAG_LAST << 1)) )

Gives a following error (does not block/crash the app however):
