When I ported the webcam driver to winXP64, I encountered 2 problem.

1. Ported driver worked smoothly with amcap.exe 32 bit. But when used the
64 bit version amcap.exe to preview with I420 format, it reported error "
This graph cannot preview". I guesses it is caused by I420 codec does not
work on WinXP64. In driver package, MsH263.drv is used.

2. Another problem with this issue is that when run HCT12.1 test, there is
error when preview, capture or playback the video with I420 format. So the
"Audio and video capture and control test item fails.

Anyone know how to resolve this issue? Thanks in advance.

Regards,
Pamela

Have you checked the manufacturer's site?

Nice to receive your reply.

The manufacturer used the MS I420 Video codec which is MSh263.drv. but it is
can not be used in 64 bit application or 64 bit Directshow applicaiton. Mayve
need verify with Microsoft engineer about the I420 Video codec in WinXP64,
But how?
