* Silence some (harmless) warnings.Frank Gevaerts2013-06-16

* Fix id3v2 album art if more than one image is present.Dominik Riebeling2013-06-15
| | | | | | | | | | | | | Rockbox only uses the first album art image (APIC / PIC frame) found in id3v2 tags. When a file contains more than one image the second one is ignored but the parsealbumart() callback overwrites the already set data. This causes the metadata structure to contain an invalid pointer to the image data, resulting in no image shown. Make parsealbumart() aware of this and skip parsing when an albumart image has already been found. Fixes FS#12870. Change-Id: Id8164f319cd5e1ee868b581f8f4ad3ea69c17f77

* SPC Codec: Refactor for CPU and clean up some things.Michael Sevakis2013-05-21
| | | | | | | | | | | | | CPU optimization gets its own files in which to fill-in optimizable routines. Some pointless #if 0's for profiling need removal. Those macros are empty if not profiling. Force some functions that are undesirable to be force-inlined by the compiler to be not inlined. Change-Id: Ia7b7e45380d7efb20c9b1a4d52e05db3ef6bbaab

* Fix opus craches with large embedded album artNils Wallménius2013-05-18
| | | | | | | | | | | | Use the tlsf malloc and friends instead of the silly codec_malloc to get actually working free and saner realloc that doesn't leak memory. Makes files with moderately sized embedded AA play on targets with large enough codec buffers and files with too large AA are now skipped rather than crashing. Fixes crash when playing example file in FS#12842. Change-Id: I06562955c4d9a95bd90f55738214fba462092b71

* Cleanup and simplify latest DSP code incarnation.Michael Sevakis2013-05-04
| | | | | | | | | | | | | | Some things can just be a bit simpler in handling the list of stages and some things, especially format change handling, can be simplified for each stage implementation. Format changes are sent through the configure() callback. Hide some internal details and variables from processing stages and let the core deal with it. Do some miscellaneous cleanup and keep things a bit better factored. Change-Id: I19dd8ce1d0b792ba914d426013088a49a52ecb7e
* Properly seek to next id3v2 frame for unsynced tags.Dominik Riebeling2013-04-26
| | | | | | | | | | | When seeking to the next id3v2 frame we need to consider if the tag has the unsync flag set. Not doing so will likely make parsing end up in the middle of the current frame if the frame size exceeds the upper limit set during read. The latter usually happens for album art frames. Fixes FS#12849. Change-Id: Ic92853eef4374508d84df347bcc66b6661d5037d

* Straighten out the mad twisted state of sound.c and related areas.Michael Sevakis2013-04-15
| | | | | | | | | | | | | | | | | | This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b
* Implement universal in-PCM-driver software volume control.Michael Sevakis2013-04-11
| | | | | | | | | | | | | | | | | | | | | | Implements double-buffered volume, balance and prescaling control in the main PCM driver when HAVE_SW_VOLUME_CONTROL is defined ensuring that all PCM is volume controlled and level changes are low in latency. Supports -73 to +6 dB using a 15-bit factor so that no large-integer math is needed. Low-level hardware drivers do not have to implement it themselves but parameters can be changed (currently defined in pcm-internal.h) to work best with a particular SoC or to provide different volume ranges. Volume and prescale calls should be made in the codec driver. It should appear as a normal hardware interface. PCM volume calls expect .1 dB units.

* VGM Codec: Improve time and fade behavior. Tweak minor misc.Michael Sevakis2013-03-06
| | | | | | | | | | | | | | | | | Prevents cutoff of tracks, especially short ones: * Extend looped tracks by fade length to fade at start of loop repeat. * No fade occurs for non-repeating track only having an intro. * Uses id3.tail_trim field to store fade duration. Use libGME built-in elapsed time reporting instead of custom calculation: * libGME already reports in milliseconds. * Don't advance time counter when Repeat == One. It just runs the progress over the length limit. Fix a comment about sample rate and set the reported bitrate to be accurate for 44.1 kHz stereo. Change-Id: I3ede22bda0f9a941a3fef751f4d678eb0027344c
