History

Michael Giacomelli b965c24c0b ffmpeg flac does actually support up to 192k sample rates, and my test file seems to decode fine, so lets enable it. Note that using 192khz is over 6 times slower then 44.1khz on my test file, so I recommend sticking to more reasonable bitrates. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28609 a1c6a512-1295-4272-9138-f99709370657		2010-11-17 00:49:09 +00:00
..
arm.h	Revert r25929. Test have shown that the assembler code is more than 50% faster than the C code both on ARM7TDMI (tested on PP5002 and PP5022) and on ARM1136JF-S (tested on Gigabeat S). If it is slower on ARM9*, it should be disabled for ARM9 only.	2010-05-10 19:05:25 +00:00
arm.S	FS#11335 by me: make ARM assembly functions thumb-friendly	2010-06-11 04:41:36 +00:00
bitstream.h	Sync codeclib bitstream code with upstream ffmpeg code. Build ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code. Speeds up cook decoding by 2-3% on h300 and flac by 25% on h300, also speeds up flac decoding by 2% on c200 (decoding speed of cook on c200 is unchanged).	2010-07-15 16:19:17 +00:00

decoder.h
golomb.h	Remove all tabs within codec path.	2010-02-22 19:44:05 +00:00
libffmpegFLAC.make	Submit FS#11381. Use -O2 for ffmpegFLAC on ARM targets. This will give reasonable speed-up (+3% on PP502x) for svn and major speed-up when switching to eabi tool chain (+9% on PP502x). Coldfire was tested to be faster when keeping -O1.	2010-06-09 06:21:28 +00:00
main.c	Make open() posix compliant api-wise. A few calls (those with O_CREAT) need the additional optional mode parameter so add it. Impact for the core is almost zero, as open() is a wrapper macro for the real open function which doesn't take the variable parameter.	2010-05-06 17:35:13 +00:00

shndec.c	Shorten: tweak some inline asm, use local lables to not cause problems when the function gets inlined, mark it as inline, tweak clobbers and use lea instead of add in one place. Fixes problems when building libffmpegFLAC with newer gcc.	2010-07-20 08:18:04 +00:00
