Description
Created attachment 373762
test case
please take a look at the attached test app,
basically glvideoflip ! glimagesink displays the right image but if video flip orientation does not change the image size (for example GST_VIDEO_ORIENTATION_180) the snapshot taken from last-sample has a wrong orientation.
I discussed about this issue with ystreey00 today and it seems there isn't a simple solution
"""
it's one of those edge cases that I'm not sure exactly where to fix it
"""
I added a workaround in my application (a videoflip element in the snapshot pipeline) but since xvimagesink (and probably d3dvideosink too) works as expected this behaviour should be at least documented. Thanks!
