Michael Sevakis	598629c3bf	SWCODEC Recording Codecs: Fix problems with hanging recording screen (chiefly on x5) when no voice file present and source is not FMRadio. Caused by extra audio stops causing encoder to unload prematurely. Fix is to have separate stop flags for each codec type to prevent collisions. Also now safe to plug into USB when recording and encoder will stay loaded and not be stopped by the call to audio_stop_playback. Additional discovery: playback will not be able to restart after a USB plug during recording. Probably an old bug. I recommend in the future that recording have higher priority on system resources than playback and playback be denied access explicitly if recording requires them. Codec API becomes incompatible so do full updates. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12579 a1c6a512-1295-4272-9138-f99709370657	2007-03-04 04:16:53 +00:00
Jens Arnold	471d881979	ARM targets: Making a few functions non-static allows us to get rid of -ffunction-sections, significantly decreasing binary size and making things run a bit faster because static functions are no longer long_call. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12349 a1c6a512-1295-4272-9138-f99709370657	2007-02-17 11:19:14 +00:00
Michael Sevakis	d52f2e4bca	Encoders: Add a little dithering with the fractional bit for mono mixdowns so faster shifts can be used again instead of division without introducing their own DC offset into the mixed channels. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12246 a1c6a512-1295-4272-9138-f99709370657	2007-02-09 18:11:11 +00:00
Michael Sevakis	3b7d703329	Encoders: Mixdown to mono should round towards zero not -infinity. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11634 a1c6a512-1295-4272-9138-f99709370657	2006-12-01 00:39:37 +00:00
Michael Sevakis	6ae46065b4	Add support for compiling encoders without adjustable CPU frequency and/or IRAM. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11625 a1c6a512-1295-4272-9138-f99709370657	2006-11-29 17:52:30 +00:00
Tomasz Malesinski	80da8b141c	FS#6357, patch 1: let iramcopy and bss share the same space in codecs and ... 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	2006-11-26 18:31:41 +00:00
Michael Sevakis	0f5cb94aa4	Big Patch adds primarily: Samplerate and format selection to recording for SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11452 a1c6a512-1295-4272-9138-f99709370657	2006-11-06 18:07:30 +00:00
Michael Sevakis	4fc717a4c1	Added FS#2939 Encoder Codec Interface + Codecs by Antonius Hellmann with additional FM Recording support and my modifications ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10789 a1c6a512-1295-4272-9138-f99709370657	2006-08-28 22:38:41 +00:00
