* volume: Add Orc-based optimised volume scalingArun Raghavan2011-03-054-0/+272
| | | | | | | | | This adds volume scaling for 1- and 2-channel software volume scaling using Orc. While testing the MMX and SSE backends on a Core2, I see an ~2x performance benefit over the hand-rolled MMX and SSE code. Since I haven't been able to test on other architectures, the Orc code is only used when MMX/SSE* is present. This can be changed in the future after testing on AMD and ARM machines.
* volume: Fix sample array size for testsArun Raghavan2011-03-053-3/+3
| | | | | | Somewhere in the history of the MMX tests, the number of channels was changed from 1 to 2, but the number of samples was not increased to make it even (multiple of the frame size).

* virtual-sink: Fix a crash when moving the sink to a new master right after ↵Tanu Kaskinen2011-02-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | setup. If the virtual sink is moved to a new master right after it has been created, then the virtual sink input's memblockq can be rewound to a negative read index. The data written prior to the move starts from index zero, so after the rewind there's a bit of silence. If the memblockq doesn't have a silence memchunk set, then pa_memblockq_peek() will return zero in such case, and the returned memchunk's memblock pointer will be NULL. That scenario wasn't taken into account in the implementation of sink_input_pop_cb. Setting a silence memchunk for the memblockq solves this problem, because pa_memblock_peek() will now return a valid memblock if the read index happens to point to a hole in the memblockq. I believe this isn't the best possible solution, though. It doesn't really make sense to rewind the sink input's memblockq beyond index 0 in the first place, because now when the stream starts to play to the new master sink, there's some unnecessary silence before the actual data starts. This is a small problem, though, and I don't grok the rewinding system well enough to know how to fix this issue properly. I went through all files that call pa_memblockq_peek() to see if there are more similar bugs. play-memblockq.c was the only one that looked to me like it might be broken in the same way. I didn't try reproducing the bug with play-memblockq.c, though, so I just added a FIXME comment there.
* 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)

| * Use <pulsecore/socket.h> instead of <sys/socket.h>Maarten Bosmans2011-02-1721-78/+38
| | | | | | | | | | | | | | | | 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.

* Fighting rewinds: Reduce calls to handle_seekDavid Henningsson2011-01-311-30/+26
| | | | | | | | | If many small blocks are in queue, handle_seek is being called for every one of them, sometimes causing a rewind. Delay the call until all blocks are handled, then call handle_seek only once. Signed-off-by: David Henningsson <david.henningsson@canonical.com>
* Fighting rewinds: Seek and write data in the same messageDavid Henningsson2011-01-311-8/+12
| | | | | | | | Allow a message in the queue to perform both a seek and a post data. For clients that do not use PA_SEEK_RELATIVE (e g gstreamer), this cuts the message count - and sometimes even the rewinds - in half. Signed-off-by: David Henningsson <david.henningsson@canonical.com>
