  1. Hi,

    I am trying to create an AVI file from monochrome U8 images using OpenCV and the FFMpeg I420 codec.
    The AVI is created (not empty file), but cannot be read either by Media Player nor OpenCV.
    It works fine with color images.
    The VFW I420 codec works fine for both monochrome and color images. Is there something I am missing with FFMpeg.
    Has anyone experienced that?

    Thanks.

  2. 1. Can ffplay play the file?
    2. Regarding the Media Player: Do you have a DirectShow Decoder installed that supports raw i420 decoding? (ffdshow might be able to)
