When we try to read one of the events and there was an error, don't
signal the callback. If the error is something else than EAGAIN log
a warning.
Especially for timerfd, EAGAIN can happen when the timer changed
while polling. This can happen when running the profiler because it
polls and updates the timer from different threads.
Make a new variable to iterate the other ports so that we can use the
original port to emit notifications.
Fixes Latency and other params set on DSP ports.
When we are simply enumerating the params, just collect the info
but don't act on them, like clearing the format or recalculating
the latency.
This avoids some useless work when enumerating params.
Use the more complete configure_format function to clear the format
and buffers when the EnumFormat param changed.
When the follower updates EnumFormat, it probably wants to renegotiate
to a new format, so clear the current format so that we do that when
starting the next time.
EnumFormat should also not only return the current format in case we
are negotiated but it should return all possible formats.
See #2832
When we try to play data but the ringbuffer is full, we need to start
the device or else we will stay in this situation forever and stay
silent.
Fixes#2830
After the ports are reconfigured, we need to perform the setup again so
that buffers and processing can happen with the right settings.
This fixes an issue when autoswitching between A2DP and HFP with
bluetooth headsets when there is also a stereo capture device available.
The input stream of the browser is quickly reconfigured between stereo
and mono with only a Pause command in between, clearing the setup state
is enough to redo the setup when going back to Playing.
Fixes#2764
Find a free id from the available ids instead of just taking the current
number of devices, which would give assign the same id to multiple
cameras when: added 0, added 1, removed 0, added 1.
This reverts commit 6c963ed933.
This code was meant to set a filter on the format for the follower
but is not implemented yet.
Problem is that the unit tests and wireplumber call this code and would
need to be patched.
port_enum_params should use right param id for SPA_PARAM_Format.
Fix typoed , instead of ; at end of line. Pop frame before putting
state.offset, in case there would be padding added (apparently usually
no).
The free buffer check must happen before writing to check for leftover data in buffers. In case data is left over from previous submission, bitpool mustn't be increased.
Also improved logging by adding bitpool to the log message.
When we get buffers from the driver, check if we have at least as many
as we requested. If we have more, that's ok, we will simply not queue
them.
Previously we would ignore the input number of buffers and use the
allocated amount to fill up the buffer array, which might be too small
and then we crash.
