-
- Version History
- ---------------
-
- v0.4
- - First release version, betatest -> lots of problems.
-
- v0.5 (not released)
- - MPEG file detection added -> no trying to play text files now!
- - Bug causing an occasionally crash at the restart of an MPEG fixed!
- - 20% faster (due to complete rewrite of DSP IDCT), and over 30% in VGA.
- - 'No press any key prompt to start the MPEG', just a 3 second delay instead, (the registered
- version has the delay removed).
- - Displays 'average frames per second' on exit.
- - Now handles non-default intra matrix (stored within MPEG -> but very rare).
- - MPEG stream error checks added, can't crash due to errors in MPEG video stream.
-
- v0.6
- - Lots check code and minor bug fixes (don't allow running on a mono monitor, file read errors etc).
- - Improvements in Huffman decoder, better DSP CPU parallelism - 5% speed increase.
- (17.62 FPS on MJACKSON.MPG in VGA (greyscale) 12.83 fps full colour :-)
- - Hopefully restores screen mode correctly on exit = there were problems with screenblaster
- (Please report if this is still not correct.)
- v0.65
- - Now skips non-intra frames, so it will play ALL Mpegs files, but obviously with 'jumps' between
- frametypes that are not supported.
- - Speed increase, (IDCT again :-). (MJACKSON.MPG is now 13.03 fps full colour).
- v0.66
- - Restores screen resolution hardware registers directly, so it should FINALLY work with screenblaster, blowup
- or any other wacky screen res enhancer you use this program with).
- v0.67
- - Supports higher res MPEGs (i.e. 352x240 etc) -> max res is now 480x384 (limit of true colour on VGA).
- - Some more tidying up of the error recovery code.
- v0.68
- - No annoying .LOD file now,the DSP code is held within main binary :-).
- - End of MPEG detection improved.
- - Grayscale version made 30% faster (removal of CR/CB IDCT).
-
- v0.70
- - MPEGs are now played direct from hard-disk - almost no speed decrease.
- - screen save/restore tweaked.
-
- To do:
-
- - Command line options (double sized pixels, frame rate limiting etc),
-
