gstreamer: non writable output buffer in do_transform_frame
Submitted by ticapix
I have a issue with Gstreamer 1.0 using the GstVideo.VideoFilter class.
The buffer of the outframe is not writable.
How data is supposed to be written back on the frame ?
(afaiu, do_tranform_frame_ip should not be used to modify buffer, but only to do read-only operation, right ?)
Sample code attached, used with python2
