What encoders does imaqOpenAVI support??

[Costas]

Hi, I'm using CVI 9.0 with VDM 8.6.4.

I want to capture an AVI movie from a USB camera with VLC, and then open the movie using the 'imaqOpenAVI' function.

Does anyone tried this before? VLC has so many encapsulation/encoding formats for capturing that I don't know which one to use.

Bytheway, what type of  encoders are supported by the imaqOpenAVI?? Yet, does the color format have to be RGB24 or I420??

Thanks a lot!

Hi Costas,

The codecs that will work with the AVI functions need to align with the DirectShow architecture in Windows. We basically use that layer to read the AVIs. So, as long as the codec can be read with DirectShow, you should have no problems with it in CVI. There unfortunately is not a list of unsupported codecs, just that requirement.

Im not sure what you mean by what color formats can be used. When you create a buffer with IMAQ, you can choose the color (RGB 32, U8 (grayscale), U16, etc) 

With regards,
