Log of running the pipeline with !videoscale!videorate!colorspace! instead of
autovideoconvert

Wow how dumb I was sending the raw file :) Logs are the "dream case" for
compressors...

Well, this time I tried as you said, replacing autovideoconvert with "!
videoscale ! videorate ! colorspace !". The gst-launch command line was like
this:

GST_DEBUG=5 gst-launch-0.10 filesrc location=flyby-xvid.avi ! decodebin2 !
videoscale ! videorate ! colorspace ! decklinksink -m


Even though, the pipeline could not play and gst complained something like
"reason not-negotiated" (I guess that refers to caps).

I think we are in the right direction now, I just need to find an appropriate
sequence of elements in this pipeline, which I though would be much easier! :)
