           Summary: deinterlace: No longer automatically deinterlace
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED

While testing on git master vs 1.2.2, I found that deinterlace does not do it's
job properly anymore, without forcing it:

Auto:
gst-launch-1.0 -v filesrc location=some.ts ! tsdemux ! mpegvideoparse !
mpeg2dec ! queue ! deinterlace mode=0 ! imagefreeze ! xvimagesink

Forced:
gst-launch-1.0 -v filesrc location=some.ts ! tsdemux ! mpegvideoparse !
mpeg2dec ! queue ! deinterlace mode=0 ! imagefreeze ! xvimagesink

On 1.2.2, auto case is properly deinterlace. I initially though it was related
to the new passthrough code, but reverting it didn't solve the issue. This may
need bisecting.
