v4l2videodec: Fails after negotiation in presence of interlace mode mixed
@ndufresne
Submitted by Nicolas Dufresne Link to original bug (#742880)
Description
The interlaced mode mixed does not actually exist in V4L2. The V4L2 decoder should fail upstream if upstream caps are using this mode. Right now it fails late hence fail the pipeline instead of letting decodebin pick a decoder that supports that. This ca be reproduce using gst-validate:
gst-validate-media-check-1.0 file:///home/collabora/gst-validate/gst-integration-testsuites/medias/defaults/mxf/op1a-mpeg2-wave_hd.mxf --expected-results /home/collabora/gst-validate/gst-integration-testsuites/medias/defaults/mxf/op1a-mpeg2-wave_hd.mxf.media_info
