2008-09-23Opening function brace style police.Michael Sevakis
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18574 a1c6a512-1295-4272-9138-f99709370657
2008-09-23Simplify synchronizaton for MPA codec and make it fully atomic, let synth ↵Michael Sevakis
thread exist for life of codec, do a bit of cleanup and use number of cores do determine if it is compiled as multithread instead of CPU type. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18573 a1c6a512-1295-4272-9138-f99709370657
2008-09-22Hopefully fix glitches when seeking in MP3s on dual core processors. Also, ↵Michael Giacomelli
clean up initialization and preprocessor commands. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18563 a1c6a512-1295-4272-9138-f99709370657
2008-09-20Commit FS#9318 - MP3 synthesis filter on COP. Loads the MP3 synth filer on ↵Michael Giacomelli
to the CoProcessor on all PortalPlayer devices, resulting in an ~90% speedup according to test_codec on the Sansa. Real world improvement is somewhat less, but still considerable. Allows MP3 decoding at 30MHz without boosting, or use of more DSP/EQ with less boosting/skipping, thus improving battery life. Minor changes to mpegplayer to retain compatibility with libmad changes. Should be no significant changes for other targets or codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18557 a1c6a512-1295-4272-9138-f99709370657

2008-06-28Updated our source code header to explicitly mention that we are GPL v2 orDaniel Stenberg
later. We still need to hunt down snippets used that are not. 1324 modified files... http://www.rockbox.org/mail/archive/rockbox-dev-archive-2008-06/0060.shtml git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17847 a1c6a512-1295-4272-9138-f99709370657
2008-04-03Move audio_set_elapsed to mpa.c, as recommended by the TODO note. Please ↵Nicolas Pennequin
correct me if affecting ci->id3->elapsed directly (ie without using ci->set_elapsed) is wrong. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16945 a1c6a512-1295-4272-9138-f99709370657
2008-03-29Move codec_get_file_pos somewhere else like the comment said should be done. ↵Michael Sevakis
Codec API version increment was needed so update all codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16874 a1c6a512-1295-4272-9138-f99709370657

implementation doesn't do what it claims any way git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15478 a1c6a512-1295-4272-9138-f99709370657
2007-11-05Don't keep useless id3v2 or other leading tag data on the buffer, it could ↵Brandon Low
be large git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15465 a1c6a512-1295-4272-9138-f99709370657
2007-02-24SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of ↵Michael Sevakis
some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12472 a1c6a512-1295-4272-9138-f99709370657
2007-02-10SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback ↵Michael Sevakis
and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12259 a1c6a512-1295-4272-9138-f99709370657
2007-02-07Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis
clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657
2006-11-26FS#6357, patch 1: let iramcopy and bss share the same space in codecs andTomasz Malesinski
plugins. Currently, in case of plugins using IRAM bss is cleared twice, once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only during codec initialization. Also, removed double variables in codecs storing a pointer to codec_api. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11606 a1c6a512-1295-4272-9138-f99709370657
2006-11-26SWCODEC: Stop clicks between tracks when resampler is active by only ↵Michael Sevakis
switching the DSP frequency and not resetting the resampler at track boundaries. Will make sure DSP is correctly flushed at dicontinuities but don't hear any problems currently. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11600 a1c6a512-1295-4272-9138-f99709370657
2006-10-27Re-enable the currently unused and broken dithering and noise shaping code ↵Thom Johansen
already in Rockbox, and make it a user option instead of a codec-controlled option. The majority of people probably will not even hear any difference with this enabled, but feedback is welcome. Save your settings! git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11368 a1c6a512-1295-4272-9138-f99709370657
2006-05-20Patch from bug report #5200 by Mark Arigo - attempt to fix gapless playback ↵Dave Chapman
after seeking in an MP3 file. It works for me, but needs more testing with a wider range of files before we can close the bug report - please post feedback on the tracker. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9962 a1c6a512-1295-4272-9138-f99709370657

2006-01-18New codec loader, using the same mechanism as the new plugin loader. API ↵Jens Arnold
version numbering restarted for the new system. Uses the target ID from configure, so don't change that too often. * Fixed sim_plugin_load_ram() to truncate the tempfile. * Reduced plugin buffer size to 512KB for iriver and iPod. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8362 a1c6a512-1295-4272-9138-f99709370657
2006-01-08Don't include the .bss and .ibss sections in the binary image for codecs and ↵Jens Arnold
plugins. Saves quite some disk space (and buffer space in case of codec changes during playback). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8308 a1c6a512-1295-4272-9138-f99709370657

2005-10-13Cleaned up the messy codec header and library system by merging codec.h, ↵Thom Johansen
lib/codeclib.[ch] and lib/xxx2wav.[ch] into just codeclib.[ch]. Deleted much of the unused code in the xxx2wav portion. All codecs should now only include codeclib.h, and whatever codec specific headers are needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7626 a1c6a512-1295-4272-9138-f99709370657
