Script that produces the "bug"
i have encountered a strange output when linking gstgltransformation with
gstglvideomixer using the following pipeline.
gst-launch-1.0 -v glvideomixerelement name=m sink_1::xpos=300 sink_2::ypos=400
sink_3::xpos=300 sink_3::ypos=400 ! glimagesink \
gltestsrc ! glupload ! gltransformation rotation-y=45 ! m. \
gltestsrc ! glupload ! gltransformation rotation-y=45 ! m. \
gltestsrc ! glupload ! gltransformation rotation-y=45 ! gldownload ! videocrop
! glupload ! m. \
gltestsrc ! glupload ! gltransformation rotation-y=45 ! gldownload ! videocrop
! glupload ! m.
Connecting gltransformation directly to the videomixer element results in a
different rotation than when i download an upload it in between.
Do you have any idea what may be the source of this difference and where i can
look into fixing it
