Poor video encoding with WMF SDK 9.5?
dbytz[ at ]yahoo.com 09.07.2007 19:30:52
Our video server when running with wmfdist90.exe (redistributal for
WMF 9.0) seems to produce a proxy wmv file with reasonable quality.
When the redistributal, wmfdist95.exe is used, the quality seems to
drop and is noticable poorer. The profile settings for the both
encodings are the same and read in from the app.config:
<streamconfig
majortype="{73646976-0000-0010-8000-00AA00389B71}"
streamnumber="2"

</videoinfoheader>

TIA for any help.
