* Implement the "volume sharing" feature.Tanu Kaskinen2011-02-264-185/+580
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have a filter sink that does some processing, currently the benefits of the flat volume feature are not really available. That's because if you have a music player that is connected to the filter sink, the hardware sink doesn't have any idea of the music player's stream volume. This problem is solved by this "volume sharing" feature. The volume sharing feature works so that the filter sinks that want to avoid the previously described problem declare that they don't want to have independent volume, but they follow the master sink volume instead. The PA_SINK_SHARE_VOLUME_WITH_MASTER sink flag is used for that declaration. Then the volume logic is changed so that the hardware sink calculates its real volume using also the streams connected to the filter sink in addition to the streams that are connected directly to the hardware sink. Basically we're trying to create an illusion that from volume point of view all streams are connected directly to the hardware sink. For that illusion to work, the volumes of the filter sinks and their virtual streams have to be managed carefully according to a set of rules: If a filter sink follows the hardware sink volume, then the filter sink's * reference_volume always equals the hw sink's reference_volume * real_volume always equals the hw sink's real_volume * soft_volume is always 0dB (ie. no soft volume) If a filter sink doesn't follow the hardware sink volume, then the filter sink's * reference_volume can be whatever (completely independent from the hw sink) * real_volume always equals reference_volume * soft_volume always equals real_volume (and reference_volume) If a filter sink follows the hardware sink volume, and the hardware sink supports flat volume, then the filter sink's virtual stream's * volume always equals the hw sink's real_volume * reference_ratio is calculated normally from the stream volume and the hw sink's reference_volume * real_ratio always equals 0dB (follows from the first point) * soft_volume always equals volume_factor (follows from the previous point) If a filter sink follows the hardware sink volume, and the hardware sink doesn't support flat volume, then the filter sink's virtual stream's * volume is always 0dB * reference_ratio is always 0dB * real_ratio is always 0dB * soft_volume always equals volume_factor If a filter sink doesn't follow the hardware sink volume, then the filter sink's virtual stream is handled as a regular stream. Since the volumes of the virtual streams are controlled by a set of rules, the user is not allowed to change the virtual streams' volumes. It would probably also make sense to forbid changing the filter sinks' volume, but that's not strictly necessary, and currently changing a filter sink's volume changes actually the hardware sink's volume, and from there it propagates to all filter sinks ("funny" effects are expected when adjusting a single channel in cases where all sinks don't have the same channel maps). This patch is based on the work of Marc-André Lureau, who did the initial implementation for Pulseaudio 0.9.15.
* core: Add a new hook PA_CORE_HOOK_CARD_PROFILE_CHANGEDColin Guthrie2011-02-252-0/+3
| | | | | | This will allow modules to know when a card profile has changed and take appropriate action. This might prove useful when developing UCM so that the appropriate verb can be set.
* core: Added new hooks: PA_CORE_HOOK_SOURCE_PORT_CHANGED and ↵Kim Therkelsen2011-02-253-0/+6
| | | | | | | | | | | PA_CORE_HOOK_SINK_PORT_CHANGED This allows modules to know when certain ports are changed. This will allow e.g. a filter module (or LADSAP) to only load when a certain port is used on the device (e.g. to only filter headphones and not normal speakers). (Comment from Colin Guthrie: This may also have use in UCM)

| | | | | | | | | | | | | | | | The check whether POSIX socket.h or WIN32 winsock2.h must be included can be made centrally. The downside is that some functionality of e.g. arpa/inet.h is also implemented in winsock.h, so that some files that don't use socket functions, but do use inet.h functions, must also include pulsecore/socket.h. (as well as arpa/inet.h)
| * Clean up <poll.h> includesMaarten Bosmans2011-02-171-1/+0
| | | | | | | | | | | | Instead <pulsecore/poll.h> should be included. That file includes poll.h on platform where it is appropriate. Also remove some unnecessary <ioctl.h> includes.
| * Use setenv instead of putenvMaarten Bosmans2011-02-171-1/+1
| | | | | | | | | | | | | | In theory putenv could be used to handle freeing of strings yourself, but this was not done in PulseAudio. That leaves no advantages in using putenv. With setenv you're at the mercy of the implementation whether the strings leak, but at least that is better then a certain leak, as it was before.

* | Allow read-only or non-existing sink input volume.Tanu Kaskinen2011-02-225-13/+60
| | | | | | | | | | | | | | | | | | | | | | | | There are two known cases where read-only or non-existing sink input volume is relevant: passthrough streams and the planned volume sharing logic. Passthrough streams don't have volume at all, and the volume sharing logic requires read-only sink input volume. This commit is primarily working towards the volume sharing feature, but support for non-existing sink input volume is also added, because it is so closely related to read-only volume. Some unrelated refactoring in iface-stream.c creeped into this commit too (new function: stream_to_string()).
* | core: Link virtual sinks and sources to their streams.Tanu Kaskinen2011-02-228-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change doesn't add any functionality in itself, but it will be useful in the future for operating on chains of sinks or sources that are piggy-backing on each other. For example, the PA_PROP_DEVICE_MASTER_DEVICE property could be handled in the core so that each virtual device doesn't have to maintain it separately. By using the origin_sink and destination_source pointers the core is able to see at stream creation time that the stream is created by a virtual device, and then update that device's property list using the name of the master device that the stream is being connected to. The same thing can be done also when the stream is being moved from a device to another, in which case the _MASTER_DEVICE property needs updating.

* build-sys: Replace dummy Makefiles with proper Makefile.am'sColin Guthrie2010-12-054-14/+40
| | | | | | | | | | | | | | | | | | | | | | | | This is needed to better support out of tree builds (including distcheck) and to ensure the necessary folders are created in the build tree on configure and also works around an intl-tools bug (https://bugs.launchpad.net/intltool/+bug/605826) The Makefile.am's used are minimal (and in some cases completely blank). At present they do not include anything interesting with the majority of the real work still done by the monolitic src/Makefile.am It may make sense to start splitting out src/Makefile.am into smaller chunks but this commit makes the minimum changes to address the issues that result from using make distcheck and other out of tree builds. Note: This 'breaks' the ability to type make in e.g. the src/modules folder and have all of PA rebuilt accordingly (this is because the static Makefiles previously present just did a "make -C ..") which was purportedly for use in emacs. But I'm sure there will be a better and more robust way to configure emacs to do your builds properly if this behaviour is still desirable.

* core: New LIFO style flist implementation v2.2Jyri Sarha2010-11-161-153/+64
| | | | | | | | | | | | The old free list implementation used objects in FIFO style. This is bad because it tries keep all the objects ever used alive and in memory. This minimizes the changes that an allocated object is already in cache. When there is shortage of physical memory this may also increase change that newly allocated object is swapped out. LIFO (e.g. stack) style free list should help these issues. Like the old one the new implementation is also lock free. This version (v2.1) of the patch has a potential weakness fixed. The previous version (2.0) did segfault when popping from empty flist, this does not.

* core: Add infrastructure for synchronizing HW and SW volume changesJyri Sarha2010-10-162-30/+363
| | | | | | | | | | | | | | | | To make concurrent use of SW and HW volume glitchles their application needs to be synchronized. For accurate synchronization the HW volume needs to be applied in IO thread. This patch adds infrastructure to delay the applying of HW volume to match with SW volume timing. To avoid synchronization problems this patch moves many of the volume and mute related functions from main thread to IO thread. All these changes become active only if the sync volume flag for a sink has been set. So, for this patch to have any effect it needs to be taken into use by sink implementor.
