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.
|

| |

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).

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.

This gets the negotiated format of sink inputs in
pa_context_get_sink_input*(). Also prints the format in 'pactl list'.

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.

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).
|

|

These aren't used any more - we handle passthrough mode in the iec958*
profiles now.
|

This adds some checks that I'd postponed and adds a
"should-be-good-enough" guess for tlength when using a compressed
format.
|
| |
| |
| |
| |
| |
| | |
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.

We weren't freeing the sink formats idxset.
|
| |
| |
| |
| |
| |
| | |
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).
|
| |
| |
| |
| | |
Handles bad format input more gracefully and returns an error instead.
|
| |
| |
| |
| | |
This is easier for clients to grok than INVALID.
|

Removes a couple of warnings and simplifies the assertion logic that
verifies format negotiation was successful.

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.

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.

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

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.
|
| |
| |
| |
| |
| | |
The properties will be used by clients to set the sample format,
sampling rate, etc. The functions will be used internally.
|
| |
| |
| |
| |
| | |
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.

(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.

This was just introduced for debugging and should not have been in the
final commit. Won't make a difference at the moment since this function
is used as a pointer, but removing this in case we change this in the
future.

PA_ALIGNED can't always guarantee that the alignment we want (the GCC
man page suggests that the linker might not be able to meet the
alignment requirements we desire). Instead, we now allocate some extra
memory and guaratee that the alignment we require is met.

And add some HAVE_[feature] variables for clarity.
|

Make use of the enable_[feature] variable automatically defined
by AC_ARG_ENABLE instead of defining our own variable.

This also includes a compatibility module that will ultimately be removed in
a future release.

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.

pa_dbus_append_basic_array_variant_dict_entry should take the direct

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.

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.
