We should not have to initialize the state to NEED_DATA, anything
that is not HAVE_DATA is good. Also we need to set the buffer to
INVALID because else it might be recycled.
There is a use case where you may want to use audioconvert with
both input & output sides configured in dsp mode, for altering
the stream volume. When it is configured like that, the
IS_MONITOR_PORT macro wrongly thinks that all output ports except
the first one are monitor ports, originating in the merger instead
of the splitter.
This change fixes that and it also completely disables exposing
monitor ports, even if they are enabled, when both sides are in
dsp mode (fmt_input_port_info() also uses the same macro to check
if the monitor ports are to be exposed)
When we finished processing the history it might be possible that we
need to skip some samples from the input. Implement this by adding
a start offset for the samples in the buffer.
We can produce data whenever the io area status != HAVE_DATA. We
don't need to look for NEED_DATA.
Also recycling buffer happens whenever the status != HAVE_DATA.
If the target node is set to 0, remove the autoconnect flag. This makes
the session manager disable stream autoconnect and some other program
needs to connect the stream to a sink or node.
Use the channelmap from the file, if available.
Add option to specify/override the channel map for playback.
Use the DSP media subtype to describe DSP formats. DSP formats
don't include the rate, channels and channel position in the
format and must use the rate and duration from the position io. This
makes it possible to later change the samplerate dynamically without
having to renegotiate the graph.
The same goes for the video DSP format, which uses the io_video_size
from the io_position to get the size/stride. Set this up in the node
based on the defaults from the context.
Make it possible to define defaults in the daemon config file, such
as samplerate, quantum, video size and framerate. This is stored in
the context and used for the DSP formats.
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
