Update of /cvsroot/datatype/tools/dtdriver/decoder/video
In directory cvs01.internal.helixcommunity.org:/tmp/cvs-serv14684

Modified Files:
      Tag: hxclient_1_5_0_cayenne
	vdecoder.cpp 
Log Message:
Description
-------------------------------------------
When transcoding video, dtdrive's current code 
will sometimes miss the last few decoded frames
from the renderer. It was calling ForceRedraw()
in a loop and then calling OnEndofPackets().

It should have been calling OnEndofPackets()
first, and then calling OnTimeSync() in a loop
until the renderer stopped bltting.

Files Modified

Branches

Testing
-------------------------------------------
Was able to get all the frames out of a decoded
video after this change
