It looks like there's nothing which ever sets any timestamps on the
video data, and without timestamps it just get played as fast as
possible then.

Also, reading raw YUV from a file like that is not really a great idea,
fdsrc will read data in its own chunk size, while the encoder probably
expects 1 buffer = 1 raw yuv frame. I'm surprised it works at all.

Try something like:

 gst-launch-0.10 filesrc location=foo.yuv ! videoparse format=xyz
width=x height=y framerate=25/1 ! TIVidenc! ! ...

See 'gst-inspect-0.10 videoparse' for all the options.

Cheers
