2008-07-01Bring libmpeg2 portions that we use up to date with the latest libmpeg2 CVS. ↵Michael Sevakis
Fix up some file headers and add a revision history to the libmpeg2 files detailing to which CVS file revisions things were synced. This makes it easier to start in the right place by hand in the future. Hopefully no mistakes and everything works. :-) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17904 a1c6a512-1295-4272-9138-f99709370657
2007-12-07Reformat and code police (tabs, trailing whitespace, annoying overuse of ↵Michael Sevakis
parentheses, etc.) in libmpeg2 so I can stomach working on it. Don't call IDCT functions through pointers - I don't feel like extracting that change just for relevance sake. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15892 a1c6a512-1295-4272-9138-f99709370657

file. Clean up the CPU selection in idct.c. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15158 a1c6a512-1295-4272-9138-f99709370657
2007-10-16Mpegplayer: Assembler optimised IDCT for coldfire, based on FS #5995 by ↵Jens Arnold
Karim Boucher. Put the IDCT block buffer in IRAM for better performance. The whole libmpeg2 decoder struct doesn't fit without throwing some libmad buffers out of IRAM, but then doesn't change performance significantly. Mpegplayer is quite usable now on X5; H300 is sort-of usable for widescreen. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15156 a1c6a512-1295-4272-9138-f99709370657
2007-10-09FS#7487 - mpegplayer - video start time seek with resumeRobert Kukla
by John S. Gwynne & Brian J. Morey This should stop the patch from breaking again and give them opportunity to improve it further. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15052 a1c6a512-1295-4272-9138-f99709370657

to come I think. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13159 a1c6a512-1295-4272-9138-f99709370657
2006-12-31fix for the inline asm in CLIP on the gigabeat by Steve Gotthard (fs#6488). ↵Marcoen Hirschberg
Turns out that gcc rearranged the ASM block without volatile git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11873 a1c6a512-1295-4272-9138-f99709370657

2006-08-08Do the clipping with inline asm instead of a huge lookup table. Tiny ↵Jens Arnold
speedup, and saves ~7.5KB of IRAM. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10493 a1c6a512-1295-4272-9138-f99709370657
2006-08-07Initial commit of work-in-progress MPEG video player plugin based on ↵Dave Chapman
libmpeg2. Works on all targets with colour LCDs, but most optimised for the ipod Color/Photo and Nano. It currently only plays raw MPEG-1 or MPEG-2 video streams (no audio). Also adds a new lcd_yuv_blit() function to the plugin API - currently only implemented for the ipod Color/Photo and Nano. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10479 a1c6a512-1295-4272-9138-f99709370657
