Detailed Description
PipeWire implementation of the audio stream interface.
Wraps a pw_stream follower node. The stream proposes SPA_AUDIO_FORMAT_F64 interleaved during format negotiation, matching the engine's internal double representation and eliminating format conversion in the hot path.
On param_changed the negotiated frame count is stored and used to validate the buffer size contract. If PipeWire adjusts the quantum away from the requested value, a warning is logged and m_stream_info.buffer_size is updated to match, consistent with the RtAudio backend's existing behaviour.
The pw_thread_loop drives the PipeWire event loop on a dedicated thread. The process callback runs on that thread at SCHED_FIFO priority when rlimits are configured by the package installer. No locking occurs on the audio path; the process callback only reads atomic state and invokes the registered std::function.
