* Implement AVDTP signal fragmentation supportJohan Hedberg2009-01-281-293/+487
| | | | | | This patch implements AVDTP signal fragmentation. Even though it's a mandatory feature it in practice it never gets used with A2DP as it requires messages that exceed 48 bytes (the minimum L2CAP MTU).
* Fix uninitialized address variableJohan Hedberg2009-01-281-0/+2

* Performance optimizations for input data processing in SBC encoderSiarhei Siamashka2009-01-285-203/+258
| | | | | | | | Channels deinterleaving, endian conversion and samples reordering is done in one pass, avoiding the use of intermediate buffer. Also this code is implemented as a new "performance primitive", which allows further platform specific optimizations (ARMv6 and ARM NEON should gain quite a lot from assembly optimizations here).
* Don't auto-disconnect explicitly created A2DP connectionsJohan Hedberg2009-01-273-1/+18
| | | | | | | | | This patch makes sure that explicitly created connections (remotely initiated or using AudioSink.Connect()) stay up until explictly disconnected. The control for this needs to be in the stream timer and not the disconnect timer since our AVDTP state machine always tries to keep one stream in configured state (i.e. it should be ok to always disconnect if we stay too long in IDLE state).
* Set the Alias only after checking the EIR dataJohan Hedberg2009-01-271-11/+11

* Fix DBusError usage with dbus_message_get_argsJohan Hedberg2009-01-261-2/+2

* Use of -funroll-loops option to improve SBC encoder performanceSiarhei Siamashka2009-01-233-17/+41
| | | | | | | | | Added the use of -funroll-loops gcc option for SBC. Also in order to gain better effect, 'sbc_pack_frame' function body moved to an inline function, which gets instantiated for 4 different subbands/channels combinations. So that 'frame_subbands' and 'frame_channels' arguments become compile time constants and can be better optimized by the compiler.
* Audio quality improvement for 16-bit fixed point SBC encoderSiarhei Siamashka2009-01-232-347/+270
| | | | | | | | | | | | | | | | | Multiplying the first part of the analysis filter constant tables by some coefficients and dividing the second part by the same coefficients is a transformation which should produce the same results if rounding errors are not taken into account. These additional C0/C1/... coefficients can be varied in a certain range (the requirement is that we still do not get overflows). The 'magic' values for these coefficients are selected in such a way that the rounding errors are minimized (rounding errors are unavoidable when putting all the floating constants into 16-bit tables and losing some of the fractional part). Also non-SIMD variant of the analysis filter is dropped because keeping it would require applying a similar change to its tables, which is a bit tricky and just increases maintenance overhead.

* SBC arrays and constant tables aligned at 16 byte boundary for SIMDSiarhei Siamashka2009-01-164-15/+36
| | | | | | | Most SIMD instruction sets benefit from data being naturally aligned. And even if it is not strictly required, performance is usually better with the aligned data. ARM NEON and SSE2 have different instruction variants for aligned/unaligned memory accesses.
* SIMD-friendly variant of SBC encoder analysis filterSiarhei Siamashka2009-01-166-160/+703
| | | | | | | | | Added SIMD-friendly C implementation of SBC analysis filter (the structure of code had to be changed a bit and constants in the tables reordered). This code can be used as a reference for developing platform specific SIMD optimizations. These functions are put into a new file 'sbc_primitives.c', which is going to contain all the basic stuff for SBC codec.
