Moving to gst-ffmpeg.

The problem is in timestamping in gst-ffmpeg. In this case, it's just using the
timestamps from the demuxer. However, the demuxer produces buffers out of order
(which is correct and fine), and so gst-ffmpeg outputs out-of-order timestamps
(NOT fine!), leading to frames being dropped.

So, someone needs to rewrite timestamping in gst-ffmpeg.

I also noticed that with filesrc ! matroskademux ! ffdec_h264 ! xvimagesink,
there were lots of decoding errors. These went away with a queue between
decoder and sink; suggests a refcounting error somewhere.
