  • support for FLV1 (Sorenson Spark) video streams
  • support for MP3 audio streams
  • generates a simple onMetaData packet

    I have to write a filter to merge two avi files frame by frame into one single AVI ? For example each frame in File-1 will be combined with corresponding frame in File-2 , in either interleaved fashion or side by side. Both files have same number of frames and frame rate. Will the mux base class written by you can be of help here ?

    not really.. you need a video processing filter to do this. You might want to look at “DirectShow Editing Services” technology. It provides a set of nice interfaces that you might find interesting.

    Hi Igor!

    Is it free for commercial usage?

  5. By Igor Janos on Nov 5, 2008

    The filter is available under the GNU GPL license. So as long as you follow the GPL rules you can use it for whatever purpose you want.

    Is it possible to create an mpg-2 file with this (further developed) filter ?

    If you replace the FLV-writer part with an MPEG-writer code then sure.

    It doesn’t work when playing muxed file using flash media server 3.
    I connected ffdshow video encoder to in 0 Pin of this filter and MP3 decoder to In 1 Pin of that.
    It can be played by using KMP but FMS…

    Is it possible to discuss commercial usage (pay you for this?) of this filter?
