* playback,talk: Share audiobuffer via core_alloc_maximum().Thomas Martitz2013-12-23
| | | | | | | | | | | | | | | | This fixes the radioart crash that was the result of buffering.c working on a freed buffer at the same time as buflib (radioart uses buffering.c for the images). With this change the buffer is owned by buflib exclusively so this cannot happen. As a result, audio_get_buffer() doesn't exist anymore. Callers should call core_alloc_maximum() directly. This buffer needs to be protected as usual against movement if necessary (previously it was not protected at all which cased the radioart crash), To get most of it they can adjust the willingness of the talk engine to give its buffer away (at the expense of disabling voice interface) with the new talk_buffer_set_policy() function.

* Get rid of some superfluous single-purpose functions in playback.Michael Sevakis2013-07-13
| | | | | | | | | | | * Remove explicit tracking of elapsed time of previous track. * Remove function to obtain auto skip flag. * Most playback events now carry the extra information instead and pass 'struct track_event *' for data. * Tweak scrobbler to use PLAYBACK_EVENT_TRACK_FINISH, which makes it cleaner and removes the struct mp3entry.

* Refactor audio thread to run both recording and playback.Michael Sevakis2013-05-31
| | | | | | | | | | | | | | | | Eliminates the pcmrec thread and keeps playback and recording engine operation mutually-exclusive. audio_thread.c contains the audio thread which branches to the correct engine depending upon the request. It also handles the main audio initialization. Moves pcm_init into main.c just before dsp_init because I don't want that one in audio_init in the new file. (Also makes revision df6e1bc pointless ;) Change-Id: Ifc1db24404e6d8dd9ac42d9f4dfbc207aa9a26e1

* GSoC/Buflib: Replace all direct accesses to audiobuf with buffer API functions.Thomas Martitz2011-08-14
| | | | | | | | | | | | | | | | | | | | | | | Namely, introduce buffer_get_buffer() and buffer_release_buffer(). buffer_get_buffer() aquires all available and grabs a lock, attempting to call buffer_alloc() or buffer_get_buffer() while this lock is locked will cause a panicf() (doesn't actually happen, but is for debugging purpose). buffer_release_buffer() unlocks that lock and can additionally increment the audiobuf buffer to make an allocation. Pass 0 to only unlock if buffer was used temporarily only. buffer_available() is a replacement function to query audiobuflen, i.e. what's left in the buffer. Buffer init is moved up in the init chain and handles ipodvideo64mb internally. Further changes happened to mp3data.c and talk.c as to not call the above API functions, but get the buffer from callers. The caller is the audio system which has the buffer lock while mp3data.c and talk mess with the buffer. mpeg.c now implements some buffer related functions of playback.h, especially audio_get_buffer(), allowing to reduce #ifdef hell a tiny bit. audiobuf and audiobufend are local to buffer.c now. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30308 a1c6a512-1295-4272-9138-f99709370657
