How to write a video decoder? RRS feed

  • Question

  • Hi,

    I have this question in my mind for a long time from I starting using K-Lite Mega Codec.

    If each company has its own codec and format, how to decode their videos?

    Even if they use mpeg/mpeg2/mpeg4 as their basic technology, they can easily change a bit to let you can not decode this stream with the standard codec.
    So I wonder how they could get so many codecs together, such as .mov, .rmvb, .avi, .wmv formats with different codecs.

    There are two questions here; one is how to decode container, one is how to decode video stream.

    I thought they should buy the spec from each company, but it seems not possibile.

    Could anyone give me some hints?

    Thanks a lot!
