原來使用康博videomate與iuvcr擷取720*480 都正常,因iuvcr無法再快樂,只好用virtualdub作擷取,開始以320*240都正常,但fromat設為720*480yuv後,預覽preview確變為綠色畫面,
用預覽overlay可看到影像,但按擷取後出現
"Warning No frames Captured.
Make sure your capture card is functioning correctly and that a valid video soure is connected,you might also try turning off overlay, reducing the image size,or reducing the image depth to 24 or 16-bit"
不管再設回為320*240也是一樣了,重開還是一樣,須將xp係統還原至virtualdub以320*240都正常時才可再用,同樣的,再將fromat設為720*480yuv後,預覽preview確變又為綠色畫面,按擷取後又出現同樣訊息.
這時若改用iuvcr或康博軟體也是都可正常擷取,記得以前的大大沒出現這樣的討論,所以po出請教一下.
