David Sutton b7267169c3 WIP 2024-05-20 09:11:57 +09:30
David Sutton ee6046cab0 alsa.go: Add chunkingRead function to abstract reading from the alsa buffer (#440) 
The chunkingRead function allows the record period to not impact on the recording buffer size of the audio. This should allow for less issues related to alsa buffer reading.

David Sutton c8f846f87d alsa: Fix sample rate negotiation (#441)

Saxon Milton c98fffe722 revid: fix manual input reader and writer 
The reader and writer pipes should be created on call to Start
and not in NewManualInput. This is so that if Close is called,
which will close the reader and the writer, a call to start will
create them again.

Saxon Nelson-Milton f3cf74ce51 cmd/vidforward: add slate image write functionality 
This includes adding facilities to handle termination signals
and err handling. Some modifications have been made to the file
input to accomodate the concurrency requirements. The slate
read mechanism is still fairly rudimentary and can only read
from a hardcoded file, but at this stage is for prototyping
purposes.

cmd/audio-netsender,device/alsa,revid: swap out ring buffer for pool buffer 
Names of config fields have been left unchanged since they appear to be lexically
coupled to behaviour and so require greater care.
