iccompress key frame setting

[Timothy Huang]

Hi,

I am using the ICCompress function to compress video, the parameter of
dwFlags is set to 0.
This parameter indicates if this is a key frame. However, I set this
parameter to 0 or ICCOMPRESS_KEYFRAME,
the return value of lpdwFlags are always AVIIF_KEYFRAME, i.e. the video
compressor always compress the
frame as a keyframe. How to use this function correctly? I used this
function for compress captured video, and the
compressed data seems like a keyframes size!!
