| psp media player new PMP (PSP Media Player)
Jonny has just released an update to PMP (PSP Media Player). This program is still under development, here is what he had to say:
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) (curious to see if a vfpu version can do better, is someone already working on this?)
experimenting on the idct now...
