I am developing a live video capturing to ASF file
program with live preview capability. I am using
Ospery card as for video capturing , ATI Radeon video
card with the latest driver and DirectShow 9 SDK for
developing my software. I am using VMR7 ( Video Mixing
Renderer 7) comming with Directshow 9 for rendering
the live preview.
I am facing a strange problem: Sometimes when I run my
filter graph (that captures video from the video
capture card and encodes it online to an ASF file
while rendering a live preview) the Video is not
displayed on the VMR and gives a black screen. This
happens irregularly. I checked the screen repainting
code and it seems to be OK
Can you help me with this issue? Is it a Video card
driver problem?
Your help is highly appretiated.
