GStreamer 1.2 for Windows, udpsink too fast

[漢障 吳]

Hello

I removed do-timstamp=true from my pipeline, then I got messages as fellow:

The pipeline remains very fast, and I guess this may not problem of udpsink but whole pipeline  or problem in GStreamer 1.2's core. ( I had tried to change udpsink to tcpserversink, the speed exactly the same, as udpsink as fast )

One problem is that you put do-timestamp=true on filesrc (don't do
that). If you set it to false, matroskademux should put proper

timestamps on the buffers.

If it works afterwards I don't know, please provide a new log then :)
