Revision 1.5, Tue Apr 6 20:07:01 2010 UTC (14 years, 2 months ago) by ratchov
aucat (server): - make the ``-m mode'' option per subdevice, allowing subdevices to be play-only or rec-only even if the server is full-duplex - add ``monitoring'' mode (with ``-m mon''). This is a record-only stream from which played streams can be recorded (kind of ``record what you hear''). - allow MIDI devices to be subscribed to the controlling MIDI port of the server, ie what midicat does (with -f option), but using the -q option. - add flow control to the protocol, and serialize clock ticks (sio_onmove() calls) and data chunks. This should fix certain full-duplex programs, broken with ``magic'' block/buffer size combinations. - enable 3 block latency which is the minimum theoretical. Make -z and -b options correspond to device parameters. - make sio_getcap(3) the same for aucat and sun backends, ie return whatever is supported (``everything'' in the aucat case, since everything is actulally supported). aucat (player): - enable ``-m mode'' option to select between monitoring and recording when ``-o file'' is used. - plug MIDI code to non-server codepath. The MIDI control device is specified with the ``-q device'' option, as in server mode. - impliment lseek()'ing within files (controlled through MIDI). Necessary to use aucat with a MIDI sequencer. midicat (thrubox): - rename ``-f'' flag to ``-q'', so it has the same name as in aucat (-f is still working) ok jakemsr@, tweaks from jmc@ |
