Because one DirectShow filter can handle many types of video streams, an information provided by {videocodec} sometimes may be not so useful. For example it may be the same "ffdshow Video Codec" for AVI files containing different video streams. Information provided by complementary {FourCC} like "DX50", "XVID", "H264", would be more useful in such case.
Thanks for the suggestion!
Thanks for implementation (in 10.0.4.2)!
