How to get some yuv420 image from h.263 decoder in ipp5.1 samples ?

[kwanjung_ryu]

Hi all.

I'm Tony Ryu.

I try to h.263 encoding and decoding some videos.

1. Get some video frames from my webcam(Kodak DVC325).

output image format is I420(YUV420).

2. Encoding that video frames using h.263 encoder in ipp5.1 samples.

And then save encoded streams.

3. Decoding that encoded streams to YUV420 images.

Display to my test application using Video For Windows APIs.

But I just see video that was drawn a lot small squares.

I used only h.263 encoder, decoder and space color converter libraries.

Can anybody help me?

Thanks a lot.

Additionally, I don't know YV12 color format exactly.

Is a YCbCr420 format?

Hello,

could you please add a little bit more details about ow you do encoding. What parameters were used. It would be nice if you can attach source frame and decoded destination frame to give us possibility to see what kind of artifacts do you get.

BTW, what hardware platform and operating system you are working on?

Regards,
Vladimir
