* 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
|
* core: Add extended stream API to support compressed formatsArun Raghavan2011-05-0225-81/+346
| | | | | | | | | | | | | | | 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
* sink: Extend API for compressed formats supportArun Raghavan2011-05-022-0/+58
| | | | | | This adds a get_formats() vfunc for sinks to provide a list of formats they can support. pa_sink_check_formats() can be used during or after routing to determine what formats from a stream the sink can support.
* format: Add some properties and internal APIArun Raghavan2011-05-023-0/+104
| | | | | The properties will be used by clients to set the sample format, sampling rate, etc. The functions will be used internally.
* core: Add a pa_format_info structureArun Raghavan2011-05-028-1/+205
| | | | | This will be used to represent the format of data provided by the client for both compressed and PCM formats in a new extended API.
* sample: Use PA_SAMPLE_INVALID instead of numeric valueArun Raghavan2011-05-021-1/+1

* sink: Trivial typo fixArun Raghavan2011-05-021-7/+7

* sink-input: Don't resample passthrough inputsPierre-Louis Bossart2011-05-021-12/+14

* filter-apply: Mark modules as being autoloadedArun Raghavan2011-05-025-11/+28
| | | | | | | (Based on Colin's review) We mark modules as being autoloaded so that they can handle this as a special case if needed (which is required by module-echo-cancel for now). This inverts how things were done and makes using these modules manually less error-prone.

* combine: Rename module-combine to module-combine-sink.Colin Guthrie2011-04-303-1352/+1429
| | | | | This also includes a compatibility module that will ultimately be removed in a future release.
* bluetooth: Only close SCO if status has changedLuiz Augusto von Dentz2011-04-301-5/+5
| | | | | In case the io thread is starting there is no point on closing SCO just to resume it latter when the source/sink changes to opened state.
* bluetooth: Fix using pointer-pointer when appending an array as variantLuiz Augusto von Dentz2011-04-301-4/+2
| | | | | pa_dbus_append_basic_array_variant_dict_entry should take the direct pointer to the array.
* bluetooth: Fix not updating sample spec when using Media APILuiz Augusto von Dentz2011-04-301-0/+13
| | | | | | When using transport configured via Media API sample spec needs to be updated since codec configuration may affect it when e.g. headset configure a different frequency or number of channels from default.
* x11: More XCB fixes.Arnaud Fontaine2011-04-302-14/+26
| | | | | | | | | | Commit 65ef80b fixed building with xcb-util >= 0.3.8, but the reply is never checked (possible SIGSEGV if the reply is NULL) nor freed (memory leak at each call of the functions). Also, remove include and dependencies on xcb-atom, as it was only meaningful for xcb_atom_get() and STRING, and depend instead on xcb >= 1.6 for XCB_ATOM_STRING.
* dbus: Fix the order of freeing stuff when unloading module-dbus-protocol.Tanu Kaskinen2011-04-291-3/+9
|
* dbus: Fix connection idxset freeing when unloading the module.Tanu Kaskinen2011-04-291-13/+8
| | | | | | | | | | | | | | If u->connections isn't empty when module-dbus-protocol is unloaded, then connection_free() is called for the remaining connections when the idxset is freed. connection_free() tries to remove the connection from the idxset, but that fails, because the item has already been removed from the idxset in this scenario. The problem is solved by not trying to remove the connection from the idxset in connection_free(). Instead, whoever wants to delete connections, has to remove the connection from the idxset in addition to calling connection_free().
* match: Support for both merging and replacing proplist updates.Tanu Kaskinen2011-04-291-37/+60
| | | | | | | | | | | | | | | | | | | | | This patch adds a new update mode specifier that can be optionally given in match rules after the regexp. Property list updates triggered by the rule will honour the given mode. The two allowed modes are 'merge' and 'replace', corresponding to PA_UPDATE_MERGE and PA_UPDATE_REPLACE respectively. If omitted, the mode defaults to PA_UPDATE_MERGE, ie. to the original behavior. For example, to force 'media.role' to be overwritten with 'bar' for streams matching foo you can use an entry like this: foo replace "bar" This will really overwrite media.role to bar even if it has already been set to something else by the application. Thanks to Krisztian Litkey for the original patch and the description above. In addition to implementing the new feature, this patch fixes a number of bugs in the parsing code.
* core: Drop empty gaps in the memblockq when playing data from it.Antti-Ville Jansson2011-04-281-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible that the memblockq of a sink input is rewound to a negative read index if the sink input is moved between sinks shortly after its creation. When this happens, pa_memblockq_peek() returns a memchunk whose 'memblock' field is NULL and whose 'length' field indicates the length of the gap caused by the negative read index. This will trigger an assert in play-memblockq.c. If the memblockq had a silence memchunk, pa_memblockq_peek() would return silence for the duration of the gap and the assert would be avoided. However, this approach would prevent the sink input from being drained and is thus not possible. Instead, we handle the aforementioned situation by dropping the gap indicated by the 'length' field of the memchunk and by peeking the actual data that comes after the gap. This scenario seems to be quite rare in everyday use, but it causes a severe bug in the handheld world. The assert can be triggered e.g. by loading two null sinks, playing a sample from the cache to one of them and then moving the created sink input between the two sinks. The rewinds done by the null sinks seem to be quite long (I don't know if this is normal behaviour or something fishy in module-null-sink).
