           Summary: CPU memory allocation error when trying to map a frame
                    buffer
    Classification: Platform
           Product: GStreamer
           Version: 1.12.0
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal

          Reporter: jeremi.wojcicki at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

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):
