* core: Add extended stream API to support compressed formatsArun Raghavan2011-05-021-1/+1
| | | | | | | | | | | | | | | This is the beginning of work to support compressed formats natively in PulseAudio. This adds a pa_stream_new_extended() that takes a format structure, sends it to the server (=> protocol extension) and has the server negotiate with the appropropriate sink to figure out what format it should use. This is work in progress, and works only with PCM streams. Actual compressed format support in some sink needs to be implemented, and extensive testing is required. More details on how this is supposed to work is available at:

* Fix checking for NULL after usageAndy Shevchenko2009-08-281-2/+1
| | | | | | The pa_xmalloc calls oom() in case of NULL pointer returned by malloc() on one hand and dereferencing of pointer is happen early than actual check on other hand. Thus, just remove useless checks.
* object: speed up type verification by not relying on strcmp()Lennart Poettering2009-08-211-2/+1
| | | | | | | | | | | | | Instead of using string contents for type identification use the address of a constant string array. This should speed up type verifications a little sind we only need to compare one machine word instead of a full string. Also, this saves a few strings. To make clear that types must be compared via address and not string contents 'type_name' is now called 'type_id'. This also simplifies the macros for declaring and defining public and private subclasses.
* sndfile: big rework of libsndfile interfacing codeLennart Poettering2009-05-261-31/+20
| | | | | | | | | This adds proper channel map handling when reading/writing audio files. This allows surround .WAV files to be played with the right channel setup automatically. This also merges paplay into pacat and adds recording into formatted files to pacat.

* rework memory block management to be thread-safe and mostly lock-free.Lennart Poettering2006-09-261-2/+7
| | | | | | | | | | | | | | | | | | | | | pa_memblock is now an opaque structure. Access to its fields is now done through various accessor functions in a thread-safe manner. pa_memblock_acquire() and pa_memblock_release() are now used to access the attached audio data. Why? To allow safe manipulation of the memory pointer maintained by the memory block. Internally _acquire() and _release() maintain a reference counter. Please do not confuse this reference counter whith the one maintained by pa_memblock_ref()/_unref()! As a side effect this patch removes all direct usages of AO_t and replaces it with pa_atomic_xxx based code. This stuff needs some serious testing love. Especially if threads are actively used. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1404 fefdeb5f-60dc-0310-8127-8f9354f1896f

* Rework memory management to allow shared memory data transfer. The central ideaLennart Poettering2006-08-181-1/+1
| | | | | | | | | | | | | | | is to allocate all audio memory blocks from a per-process memory pool which is available as read-only SHM segment to other local processes. Then, instead of writing the actual audio data to the socket just write references to this shared memory pool. To work optimally all memory blocks should now be of type PA_MEMBLOCK_POOL or PA_MEMBLOCK_POOL_EXTERNAL. The function pa_memblock_new() now generates memory blocks of this type by default. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1266 fefdeb5f-60dc-0310-8127-8f9354f1896f
