* osx: pass -headerpad_max_install_names to the linker, tooDaniel Mack2011-05-301-1/+1
| | | | | This option won't make it to the actual libtool command which does the linking when not prefixed with -Wl,
* alsa-mixer: Fix the assumption that volume is always positiveLu Guanqun2011-05-301-1/+5
| | | | | | | | | | | | | | | | | Add a variable to track whether the actual volume is set or not. Suppose this: min volume: -126 max volume: 0 then when user wants to set some constant volume to -10, it would fail. While the alsa values are typically positive, some values are "funky" and have negative values. It is desirable to fix this at the alsa level so that the numbers are positive, but it's not technically invalid, and thus we have to support it. Discussed here: http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/9832 and http://thread.gmane.org/gmane.linux.alsa.devel/85459
* echo-cancel: Fix a crash is speex cleanupArun Raghavan2011-05-281-1/+2
| | | | | | If module initialisation fails, the speex done() function might try to free a value that's not been allocated yet. Adding protection for this condition.
* echo-cancel: Fix echo suppression, add some knobsBart Cerneels2011-05-282-3/+36
| | | | | | | The echo suppress attenuation value was being incorrectly modified. Fixed and added 2 arguments to change the attenuation of the residual echo filter. Default values of the speex preprocessor will be used when omitted.
* echo-cancel: Speex preprocessor has to run *after* the AEC.Bart Cerneels2011-05-281-3/+4
| | | | This is how it is expected to be run.
* echo-cancel: Add speex preprocessingArun Raghavan2011-05-242-3/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows the selective enabling of speex' preprocessing algorithms before running the echo-canceller -- for now this includes automatic gain control, noise suppression and echo suppression. It's all off by default for now, though at some point in the near future we might want to enable at least denoising by default. The denoising works pretty well, though we might want to add a way to tweak the noise-suppression knob that libspeex provides. The AGC option is just a stop-gap -- we need a real AGC mechanism that tweaks the source volume rather than doing this in software. The speex documentation mentions VAD and dereverb, but it appears that these are not complete yet. We don't do all this in a separate module from module-echo-cancel to avoid the overhead of adding another virtual source. It makes more sense to make a separate virtual source module that can be used for cases where preprocessing is useful but AEC is not (for e.g. noise suppression for fan noise in a recording application). Another reason to keep this integrated with the AEC module is that the echo suppression bits use the speex echo canceller state. This does leak some information about the AEC implementation into module-echo-cancel, but this is unavoidable.
* format: Fix channel map handlingArun Raghavan2011-05-202-7/+9
| | | | | Channel map handling in the extended API was broken. Thanks for Milos_SD for pointing this out on IRC.
* echo-cancel: Remove extraneous debug messageArun Raghavan2011-05-201-1/+0
| | | | This was making it impossible to run in debug mode with save_aec=1
* echo-cancel: Don't overpad variableArun Raghavan2011-05-161-1/+1
| | | | The padding was to be 16 bytes, not 16 elements.
* build-sys: Link libpulse directly to libdbus-1 if neededSjoerd Simons2011-05-161-1/+6
| | | | | | Linking libpulse with gold or when using ld --no-add-needed fails as libpulse uses dbus methods directly but isn't explicitly linked to it. So link to it when needed :)
* protocol-native: Fix memory leaks introduced in protocol 21 (passthrough ↵Colin Guthrie2011-05-161-26/+30
| | | | | | | | | | | support) The proplist used may never be freed if an error condition was found with CHECK_VALIDITY macro and the formats idxset was never freed regardless of error state. This change fixes adds a new maco CHECK_VALIDITY_GOTO() which allows for cleanup to be done before returning.

* bluetooth: Fix early return styling and add missing return valueColin Guthrie2011-05-151-5/+6
| | | | Thanks to Tanu Kaskinen for pointing out the missing return.
* suspend-on-idle: Trigger mempool vacuumingJyri Sarha2011-05-151-1/+40
| | | | | | | | In a setup with one or more filter sinks or sources there is always at least one stream existing. In such a situation normal mempool vacuuming never happens. This patch causes suspend-on-idle module to vacuum memory when ever it notices that all sinks and sources are suspended. The behavior can be enabled with a module parameter.
* protocol-native: Stop auto timing updates if connected to suspended sink or ↵Jyri Sarha2011-05-151-4/+24
| | | | | | | | | | | | | source This quite is an old patch. It was added to N900 to avoid unnecessary wake-ups when the phone is in power save mode (= blank screen and no user interaction). In this situation if the user had a browser window with flash animation open pulseaudio kept waking up every 10 seconds, causing a severe hit to use times. Anyway I do not see any reason to send timing updates if the sink or source where the stream is connected to is suspended.

* tests: Fix resampler-test.Colin Guthrie2011-05-151-4/+3
| | | | | | | | | | This has been broken since c376ac5920fdeb46ca844d9518e22f17adffb635 when run without any arguments. Passing in -v (verbose) caused the test to work fine. I think this oversight is just a thinko in the original work but it obviously broke 'make check' and thus distcheck. Also fix a couple compiler warnings.

| * module-tunnel: Update for recent protocol changesArun Raghavan2011-05-151-0/+59
| | | | | | | | | | | | | | | | | | This updates the tunnel module for protocol version >= 19. module-tunnel-sink does not proxy server-side passthrough support (yet). This would require a few more changes, namely keeping track of what formats are available and if any other sink inputs are connected on the server-side.
| * doxygen: generate documentation for format.hArun Raghavan2011-05-151-1/+1
| |
| * format: Add some convenience API for setting propertiesArun Raghavan2011-05-153-3/+38
| | | | | | | | | | Adds functions to set sample format, rate, channels and channel map on a format to make life easier for users of the API.
| * format: Extend properties to handle lists/rangesArun Raghavan2011-05-157-22/+389
| | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the simple string used by pa_format_info's proplist with a JSON string (accessed via new API only). This allows us to express lists and ranges more cleanly, and embed type information for future extensibility. We use json-c for JSON parsing. This is a lightweight depdency (32 KB on my system) and avoids the hassle of having to reinvent a JSON parser. Also included is a test which verifies functionality and is valgrind-clean.
| * sink-input: Provide more information to client when format is lostArun Raghavan2011-05-152-1/+13
| | | | | | | | | | | | | | | | When the sink format changes and we kill the stream, clients need a way to know (a) what device they should reconnect to, and (b) what the stream running time was when the stream got killed (pa_stream_get_time() won't work after the stream has been killed). This adds these two bits of information in the event callback's proplist parameter.
| * format: Add correct sample spec conversion for E-AC3Arun Raghavan2011-05-151-0/+3
| | | | | | | | | | | | | | IEC61937-encapsulated E-AC3 frames contain 6 audio blocks per substream, which corresponds to 1536 samples contained a 24576-byte frame. To cope with this, we maintain the s16le stereo sample spec, but quadruple the sample rate so that the conversion remains accurate.
| * format: Export pa_format_info_is_compatible in APIArun Raghavan2011-05-154-2/+11
| | | | | | | | This allows clients to perform checks between formats as well.
| * sink-input: Add a format-lost eventArun Raghavan2011-05-152-1/+9
| | | | | | | | | | | | | | This event is emitted if the sink-input could not be moved to a new sink because it doesn't support the format of the sink-input. Clients can reconnect their stream with a different format if they wish or gracefully exit.
| * sink-input: Don't restore volume for passthrough streamsArun Raghavan2011-05-151-0/+6
| |
| * sink-input: Don't print an error if a passthrough connection failsArun Raghavan2011-05-151-1/+2
| | | | | | | | | | | | The assertion message is misleading, since the passthrough connection can fail for reasons the client has no control over (like other sink inputs being connected).
| * core: Factor out passthrough checks into their own functionsArun Raghavan2011-05-024-17/+41
| | | | | | | | | | | | | | | | | | | | Since we currently have two mechanisms to signal a passthrough connection (non-PCM format or PA_SINK_INPUT_PASSTHROUGH flag), we move all the related checks into functions and use those everywhere. This makes things more consistent, and should we decide to get rid of the flag, we only need to change pa_sink_input_*_is_passthrough() accordingly.
| * format: Add a type for DTSArun Raghavan2011-05-022-0/+4

| * introspect: Get format of sink inputArun Raghavan2011-05-025-2/+16
| | | | | | | | | | This gets the negotiated format of sink inputs in pa_context_get_sink_input*(). Also prints the format in 'pactl list'.
| * introspect: Get formats for sinksArun Raghavan2011-05-025-1/+68
| | | | | | | | | | This gets the list of supported formats for a sink in pa_context_get_sink_info*(). Also prints these in 'pactl list'.
| * stream: Add API to get a stream's pa_format_infoArun Raghavan2011-05-023-0/+14

| * format: Add some convenience functions for printingArun Raghavan2011-05-023-0/+51

| * format: Const-ify some parametersArun Raghavan2011-05-022-4/+4
| |
| * alsa: Reconfigure sink sample rate for passthrough inputsArun Raghavan2011-05-021-0/+52
| | | | | | | | | | | | When a passthrough sink-input is added, we need to reconfigure the sink's sample rate since no resampling occurs. We revert to the original rate when the passthrough sink-input is removed.
| * core: Suspend monitor when a sink enters passthrough modeArun Raghavan2011-05-023-1/+18
| | | | | | | | | | | | | | | | | | | | | | In most cases it is expected that clients cannot consume compressed data from monitor sources, so we suspend the monitor source when the sink goes into passthrough mode. Eventually, when the extended API includes client notifications for changed formats, we should emit a notification on the monitor so that clients can decide what they want to do when this happens (disconnect or consume the data anyway).
| * sink: Trivial typo fix in commentArun Raghavan2011-05-021-1/+1
| |
| * alsa-mixer: Remove passthrough profilesArun Raghavan2011-05-023-28/+1
| | | | | | | | | | These aren't used any more - we handle passthrough mode in the iec958* profiles now.
| * core: Fix some FIXMEs for the extended APIArun Raghavan2011-05-022-10/+26
| | | | | | | | | | | | This adds some checks that I'd postponed and adds a "should-be-good-enough" guess for tlength when using a compressed format.
| * sink-input: Kill passthrough streams if moving to an unsupported sinkArun Raghavan2011-05-023-0/+33
| | | | | | | | | | | | This will eventually be replaced by a hook to let clients know that the stream has moved so that they can gracefully reconnect and renegotiate a supported format.
| * sink: Fix leak in pa_sink_check_formats()Arun Raghavan2011-05-021-1/+4
| | | | | | | | We weren't freeing the sink formats idxset.
| * format: Avoid some code duplicationArun Raghavan2011-05-024-14/+12
| | | | | | | | | | | | We frequently need to free an idxset containing pa_format_infos, so define an internal free function that can be used directly with this (instead of defining it once-per-file).
| * sink-input: Don't assert on bad formatsArun Raghavan2011-05-023-17/+21
| | | | | | | | Handles bad format input more gracefully and returns an error instead.
| * sink-input: Return NOTSUPPORTED if format negotiation failsArun Raghavan2011-05-021-1/+1
| | | | | | | | This is easier for clients to grok than INVALID.
| * sink-input: Minor cleanupsArun Raghavan2011-05-021-5/+5
| | | | | | | | | | Removes a couple of warnings and simplifies the assertion logic that verifies format negotiation was successful.
| * tests: Add a trivial test for the extended APIArun Raghavan2011-05-022-0/+203
| | | | | | | | | | | | This is just sync-playback.c modified to use the extended API. We need something more sophisticated for properly testing the compressed formats, but that is a non-trivial task in itself.
| * sink: Remove PASSTHROUGH flagArun Raghavan2011-05-025-59/+40
| | | | | | | | | | | | | | This removes the passthrough flag from sinks since we will drop exclusively passthrough sinks in favour of providing a list of formats supported by each sink. We can still determine whether a sink is in passthrough mode by checking if any non-PCM streams are attached to it.
| * format: Add convenience API to check if a format is PCM or notArun Raghavan2011-05-023-0/+8
