DirectShow video decoders are not even required to tell you the frame rate of the incoming video.This limitation doesn't apply to AVI files, or to any other format for which there's a frame-accurate DirectShow decoder. As long as you just read a portion of the video sequentially you should be fine, but heaven help you if you want to do anything more complicated. DirectShow video decoders are not required to support frame-accurate seeking, and most don't.Some decoders (notably MS MPEG-4) will produce upside-down video.I could add this if there's any demand for it. It's now almost true that it can read any format which Windows Media Player can play. There's an all-new, 100% rewritten DirectShowSource filter which supports a lot more file formats than the old one.AddBorders, Letterbox, and SeparateFields are fixed.The following things changed between the first beta and the second beta: This may resolve some problems people were having with this filter.
