2014-08-16Fix warnings from 6ed0087Michael Sevakis
Forgot to (void) an unused parameter when priorityless. usb-drv-rl27xx.c was using a compound init to initialize a semaphore but the structure changed so that it is no longer correct. Use designated initializers to avoid having to complete all fields. Forgot to break compatibility on all plugins and codecs since the kernel objects are now different. Take care of that too and do the sort thing. Change-Id: Ie2ab8da152d40be0c69dc573ced8d697d94b0674

2013-06-30Update software recording engine to latest codec interface.Michael Sevakis
Basically, just give it a good rewrite. Software codec recording can be implemented in a more straightforward and simple manner and made more robust through the better codec control now available. Encoded audio buffer uses a packed format instead of fixed-size chunks and uses smaller data headers leading to more efficient usage. The greatest benefit is with a VBR format like wavpack which needs to request a maximum size but only actually ends up committing part of that request. No guard buffers are used for either PCM or encoded audio. PCM is read into the codec's provided buffer and mono conversion done at that time in the core if required. Any highly-specialized sample conversion is still done within the codec itself, such as 32-bit (wavpack) or interleaved mono (mp3). There is no longer a separate filename array. All metadata goes onto the main encoded audio buffer, eliminating any predermined file limit on the buffer as well as not wasting the space for unused path queue slots. The core and codec interface is less awkward and a bit more sensible. Some less useful interface features were removed. Threads are kept on narrow code paths ie. the audio thread never calls encoding functions and the codec thread never calls file functions as before. Codecs no longer call file functions directly. Writes are buffered in the core and data written to storage in larger chunks to speed up flushing of data. In fact, codecs are no longer aware of the stream being a file at all and have no access to the fd. SPDIF frequency detection no longer requires a restart of recording or plugging the source before entering the screen. It will poll for changes and update when stopped or prerecording (which does discard now-invalid prerecorded data). I've seen to it that writing a proper header on full disk works when the format makes it reasonably practical to do so. Other cases may have incorrect data sizes but sample info will be in tact. File left that way may play anyway. mp3_enc.codec acquires the ability to write 'Info' headers with LAME tags to make it gapless (bonus).

2012-05-03Add rbcodecplatform.h and rbcodecconfig.h.Sean Bartell
librbcodec users must provide these two files when the library is built. rbcodecconfig.h provides configuration #defines and basic types, and will be included by public librbcodec headers, so it must not conflict with the user's code. rbcodecplatform.h provides various OS functions, and will only be included by source files and private headers. This system is intended to provide maximum flexibility for use on embedded systems, where no operating system headers are included. Unix systems can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with minimal changes.

2012-04-29Fundamentally rewrite much of the audio DSP.Michael Sevakis
Creates a standard buffer passing, local data passing and messaging system for processing stages. Stages can be moved to their own source files to reduce clutter and ease assimilation of new ones. dsp.c becomes dsp_core.c which supports an engine and framework for effects. Formats and change notifications are passed along with the buffer so that they arrive at the correct time at each stage in the chain regardless of the internal delays of a particular one. Removes restrictions on the number of samples that can be processed at a time and it pays attention to destination buffer size restrictions without having to limit input count, which also allows pcmbuf to remain fuller and safely set its own buffer limits as it sees fit. There is no longer a need to query input/output counts given a certain number of input samples; just give it the sizes of the source and destination buffers. Works in harmony with stages that are not deterministic in terms of sample input/output ratio (like both resamplers but most notably the timestretch). As a result it fixes quirks with timestretch hanging up with certain settings and it now operates properly throughout its full settings range.
