* Don't mix front-center into rear channelsLennart Poettering2008-12-171-3/+93
| | | | | | | | If there's a center channel on input that is not available on output make sure we mix front-center only into front-left/right and rear-center into rear-left/right. Closes #400

* rework memory block management to be thread-safe and mostly lock-free.Lennart Poettering2006-09-261-119/+128
| | | | | | | | | | | | | | | | | | | | | 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 the resample to allocate temporary memory with pa_memblock_new() ↵Lennart Poettering2006-08-191-25/+58
| | | | | | instead of pa_xrealloc() git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1291 fefdeb5f-60dc-0310-8127-8f9354f1896f
* Rework memory management to allow shared memory data transfer. The central ideaLennart Poettering2006-08-181-10/+11
| | | | | | | | | | | | | | | 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
