           Summary: rotate plugin docs say that 'angle' is in radians, yet
                    seems to be in degrees
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: rory at technomancy.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


The documentation (via gst-insepct) for the rotate plugin in -bad says that the
angle paramters is in radians, however when i use it it seems to be in degrees.

Firstly angle=45 produces a good 4͏5° rotated angle, and angle=30 shows the
video rotated at 30͏°. angle=0.78 (0.78 radians is approximately 45͏°) shows
the video only rotated by a little small amount, not 45͏°.

I am using version 0.10.22-2ubuntu4 from ubuntu.

Either the documentation or the code should be changed.
