2009-08-08Fix FS#10476. Prevent FLAC bitrate calculation overflow with large files. ↵Boris Gjenero
The watermark depends on the bitrate, and so this also fixes playback pauses on large FLAC files. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22211 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
