Video Capture - Interlacing problems
 

Hello again,

This is my second question. By referring to my earlier post entitled "Need help - Install Driver for Video Capture Card", 505455. I already solved the problem, thanks to kilgoretrout.
Recently, I captured videos using opencv-0.9.9. My capture card is Hauppauge ImpactVCB 558. The problem is that there is interlacing problem in the videos especially on moving objects. How to solve this problem?

Thank you in advance for the help.

When you re-encode the capture, you can use a deinterlace filter. For example:

ffmpeg -i some.mpg -deinterlace -sameq some.avi

In my case I grabbed the video sequences from a VCR(VHS tape) or directly from a camera, and displayed the sequences on the screen. In both situations, the interlacing problem occurred, especially in fast moving objects.

When I enter dmesg, part of the result shows:

bttv: i2c: checking for MSP34xx @ 0x80... not found
bttv: i2c: checking for TDA9875 @ 0xb0... not found
bttv: i2c: checking for TDA7432 @ 0x8a... not found

Are those related to the interlacing problem?

Thank you in advance for the help.
