Foil 9 Decoders: Current Technology

VfW: Display Control Interface architecture; DCI API allows for off-loading color space conversion to HW accelerator. Resulting performance improvement allows for larger final picture and less demanding network protocol handling.
Software decoders available for all codecs; performance ranging from adequate (VfW, QT) over moderate (M-JPEG) to very poor (MPEG).
Only fastest RISC CPUs can decode MPEG in real time.
For VfW and QT, full screen 30 fpu video requires HW support as well.
Hardware playback options:
MPEG: (1) decoder cards for external monitors only; (2) MPEG decoder cards using VGA feature connector to integrate MPEG & VGA; (3) proprietary integration of MPEG and VGA (VESA Media Channel)
