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
2007-11-05Remove conf_filechunk, it should never have been a setting and its ↵Brandon Low
implementation doesn't do what it claims any way git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15478 a1c6a512-1295-4272-9138-f99709370657

non-standard sampling rates git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14289 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

2006-04-15Put new_track on the codec_api, and use it instead of the reload_codec ↵Brandon Low
variable in most places. Should help with problems people have had with GUI vs. playback sync. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9670 a1c6a512-1295-4272-9138-f99709370657
2006-03-26Eliminate references to "long" types for 64-bit compiles; return audio dataDave Bryant
in Rockbox standard S3.28 format git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9272 a1c6a512-1295-4272-9138-f99709370657
2006-02-06Streamlined WavPack decoder by utilizing dsp functionality where it wasDave Bryant
applicable (like mono conversion and clipping) and eliminating the conversion to 16-bit samples (everything is now returned as 28-bit). This reduced boost ratio (on iRiver) by about 7% on those tracks that require it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8598 a1c6a512-1295-4272-9138-f99709370657
2006-01-18Part of the profiling patch to use a consistent return path in all codecs to ↵Brandon Low

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
2005-11-18More stable playback with reduced stuttering when skipping tracks.Miika Pekkarinen
Removed CODEC_SET_FILEBUF_LIMIT setting; now playback.c determines how to buffer the files. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7970 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
2005-09-30Fix some WavPack bugs by forcing DSP use even when not needed for sampling rateDave Bryant
conversion or ReplayGain. Costs about 12% boost ratio when DSP would not have been used before. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7573 a1c6a512-1295-4272-9138-f99709370657

virtually to crash. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7096 a1c6a512-1295-4272-9138-f99709370657
2005-06-30Not sure if this is the right way to make "resume" work correctly for WavPack,Dave Bryant
but it seems to work and if it's wrong it should only affect WavPack... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6938 a1c6a512-1295-4272-9138-f99709370657

2005-06-26Initial DSP implementation. DSP supports resampling audio stream fromMiika Pekkarinen
codecs (currently works corrently only with mp3's, somebody should fix that). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6877 a1c6a512-1295-4272-9138-f99709370657

2005-06-22moved and renamed the codecs, gave the codecs a new extension (.codec),Daniel Stenberg
unified to a single codec-only API, made a new codeclib, disabled the building of the *2wav plugins git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6812 a1c6a512-1295-4272-9138-f99709370657
