* 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: http://pulseaudio.org/wiki/PassthroughSupport

* Limit rate adjustments to small, inaudible jumpsMaarten Bosmans2011-01-161-13/+21
| | | | | | | | | | | | | | | The same logic is applied to the sample rate adjustments in module-rtp-recv, module-loopback and module-combine: - Each time an adjustment is made, the new rate can differ at most 2‰ from the old rate. Such a step is equal to 3.5 cents (a cent is 1/100th of a semitone) and as 5 cents is generally considered the smallest observable difference in pitch, this results in inaudible adjustments. - The sample rate of the stream can only differ from the rate of the corresponding sink by 25%. As these adjustments are meant to account for very small clock drifts, any large deviation from the base rate suggests something is seriously wrong. - If the calculated rate is within 20Hz of the base rate, set it to the base rate. This saves CPU because no resampling is necessary.

* Base mainloop on pa_rtclock_now()Marc-André Lureau2009-06-201-10/+5
| | | | | | | | | | | | | | | | Move the mainloop to monotonic based time events. Introduces 4 helper functions: pa_{context,core}_rttime_{new,restart}(), that fill correctly a timeval with the rtclock flag set if the mainloop supports it. Both mainloop-test and mainloop-test-glib works with rt and timeval based time events. PulseAudio and clients should be fully functional. This patch has received several iterations, and this one as been largely untested. Signed-off-by: Marc-André Lureau <marca-andre.lureau@nokia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixups' on resuming The primary reason for this change is to allow time graphs that do not go through the origin and hence smoothing starting from the origin is not desired. This change will allow passing time data into the smoother while paused and then abruptly use that data without smoothing using the 'quick fixup' flag when resuming. Primary use case is allowing recording time graphs where the data recorded originates from a time before the stream was created. The resulting graft will be shifted and should not be smoothened to go through the origin.

A fresh look after work made the resampler initialization code pop out. The problem is in the sink connection being made from "module-rtp-recv.c", the "PA_SINK_INPUT_VARIABLE_RATE" flag should be passed into "pa_sink_input_new", but is not there. Made the change and tested it, fixes the problem. Checked and head-of- tree off of the pulseaudio.org source browsing link does not have this fix either. One-liner patch attached.

* Rework memory management to allow shared memory data transfer. The central ideaLennart Poettering2006-08-181-6/+5
| | | | | | | | | | | | | | | 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
