           Summary: v4l2src: Caps failure on raspberry pi
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: robert.swain at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


I would expect a simple command line such as:

gst-launch-1.0 v4l2src ! video/x-raw,width=1280,height=720 ! glimagesink

...to work at least somewhat. Ideally it would work entirely smoothly but
perhaps the v4l2src raw output to glimagesink stuff isn't tweaked to work as
efficiently as it should. I would guess v4l2src should write directly into GL
memory if it can. That would be great.

What actually happens is a not-negotiated error is met. Looking at the v4l2src
debug log, it probes for formats and resolutions, except it identifies the
min/max width/height and step sizes and then only probes square resolutions
within that range.
