avviddec: Negotiation failure for alternate interlace stream if deinterlace element is not configured
Regression since !115 (merged)
Using hevc interlace stream available at https://trac.ffmpeg.org/ticket/5514, following pipeline doesn't work
gst-launch-1.0.exe -v filesrc location=src13_interlaced_cut.265 ! h265parse ! avdec_h265 ! d3d11videosink
glimagesink
and d3dvideosink
are showing the same nego failure as well. In case that deinterlace is configured between dec and sink, it works nicely of course.
(I'm sorry, @vivia)
