  18. @head3 Introduction |
  19. The vcmStreamXXX APIs are defined to simplify integration of video
  20. compression and decompression in NetMeeting's datapump. Currently, the datapump
  21. behavior relies a lot on the acmStreamXXX APIs. In order to limit the amount of modifications that need to be applied
  22. to the datapump, we define video compression APIs with a behavior similar to
  23. the audio compression APIs. Integration in the datapump will be achieved by defining
  24. a FilterVideoManager class identical to the FilterManager class, where calls to
  25. acmStreamXXX functions are simply replaced by calls to vcmStreamXXX functions.
