Johnny has updated the PSP Media Player, heres what he posted:
changes:
the color space conversion (PIX_FMT_YUV420P -> PIX_FMT_RGBA32) is now done in asm + me
(note: no check for PIX_FMT_YUV420P, some codecs could be broken with this)
some numbers (talking about **csc only** with 480x272 res - @333mhz):
ffmpeg original: ~52 fps
my c version: ~64 fps
my asm version: ~70 fps (lol it's my first mips code, maybe someone could enter here and at least get a better instructions reordering)
asm + me: ~135 fps :O
this traduces in + 4-5 fps for 480x272 mpeg4sp @900 kbps
(low bitrates/resolutions have more speedup - due to a less idct bottleneck)
Get trying those avi and mpeg files and report back
