DM368 1080i encoding

pengfei zhan1

Hello:

I am tryint to use the DM368 to process the 1080I format video data. The camera is 1080i@60fps,and I use the H264 encoder. But the output is 30fps,and the encode time is longer than 1080p,about 3ms. So I want to know that how DM368 to process the 1080i video data,and why it spend longer time than 1080p,and the output is 30fps. I do not set the halfRateCapture .IS it integration the Odd and Even Field data ,When dm368 process the 1080i video data.

Thanks, look forward to your reply, I wish a happy work!

Hi，
I used the default parameter settings and use the dvsdk_4. I find an Interesting Phenomenon,When the screen display the Letter E，and we found the Part of the horizontal line is Missed part of something. It like that the horizontal line missed something. SO I Guess When the camera is 1080I @60, the dm368 only Obtain Odd field or even field, and Copy the obtained data ,Make up The amount of data 1920x080x1.5. Then send the data to the encoder .
