2011-08-14GSoC/Buflib: Replace all direct accesses to audiobuf with buffer API functions.Thomas Martitz
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
2011-03-16More robust implementation of MPEG frame header search. The parser will not ↵Andree Buschmann
only search for the very first byte sequence that looks like a valid MPEG frame header. It will search for a valid MPEG frame header sequence, decode it, and probe if there is a consecutive MPEG frame header of the same type (MPEG version, layer, sampling frequency) at the expected position. This approach will reduce false detection of MPEG frame headers in case of errorous metadata or garbaged files. Fixes FS#12007. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29603 a1c6a512-1295-4272-9138-f99709370657

2005-09-15Archos recording/playback: (1) Xing header creation: * Now estimates the ↵Jens Arnold
framecount from the recording time if the MAS frame counter saturates, so it always writes a valid Xing header. * Reverted my brainless short-xing-header change. This was only valid for layer 3. (2) Xing/VBRI header evaluation: Fixed possible overflow in bitrate calculation. (3) MPEG thread: Avoid double chunk size limiting for the rare case of 8 MB modded Ondios. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7522 a1c6a512-1295-4272-9138-f99709370657
2005-09-10Reworked handling of MPEG audio frame & file info: * Fixed frame size ↵Jens Arnold
calculation for layer 1 (all versions) and layer 2 (V2/V2.5). * Exact frame time (expressed as a fraction) for way more precise playtime calculation at 44100/22050/11025Hz sample frequency. * Exact playtime<->position conversion for CBR also used for resume position. * More compact code, long policy. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7505 a1c6a512-1295-4272-9138-f99709370657
2005-09-04Archos recording: Always prepend ID3V2 and Xing header to a recording file, ↵Jens Arnold
