Alexandre Ratchov 2606d3f24e Add support for FreeBSD raw usb-midi devices. Bits from Tobias 
Kortkamp <t@tobik.me> plus configure script tweaks.

Alexandre Ratchov 9cb5193ca7 sio_oss.c: In full duplex-mode, don't require play and rec 
buffer sizes to be the same. Only the block sizes need to be the
same.
 2016-11-05 07:21:28 +01:00
Alexandre Ratchov 8c95537698 sio_oss.c: Disallow tiny fragment sizes, as they may overload 
the system. And as sndiod runs with increased priority, it would
consume all the cpu and could in turn hang the system.
 2016-11-05 07:14:46 +01:00
Alexandre Ratchov c25d86c7db sio_oss.c: if the requrested block size is a power of two 
make the oss block size calculation return the requested value.
 2016-11-05 07:11:08 +01:00
Alexandre Ratchov 4f56ff6181 In sio_oss_revents() use the fifo_samples counter returned 
by SNDCTL_DSP_CURRENT_{I,O}PTR to determine the device current
position. Besides being simpler than using the absolute position,
this fixes hangs in record-only mode.
 2016-11-05 07:02:39 +01:00
Alexandre Ratchov c5daeee294 On OSS/FreeBSD, set poll(2) threshold to 1 byte, so that it returs 
POLLIN/POLLOUT whenever read/write can be called without blocking. By
default OSS use 1 block of threshold.
 2016-11-04 19:12:07 +01:00
Alexandre Ratchov 2b58ec0677 Remove forgotten debug printf in sio_oss.c 2016-11-04 14:14:52 +01:00
Alexandre Ratchov db20298468 Use the SNDCTL_DSP_SETTRIGGER interface to start/stop the device, this 
allows the "onmove" callback to be called whenever the DMA actually
starts (and not on the first write). This also removes the need for
sio_osee_setpar() call every time the device is stopped.
 2016-11-04 14:09:42 +01:00
Alexandre Ratchov 9be2c65600 Allow programs using OSS/FreeBSD backend to select the buffer size. 
According to kernel sources, SNDCTL_DSP_POLICY ioctl doesn't seem to
always set play and rec buffer sizes to the same value.  That's why we
use the SNDCTL_DSP_SETFRAGMENT ioctl instead.
 2016-11-04 11:03:41 +01:00
Alexandre Ratchov a282420a49 In OSS/FreeBSD sio_setpar(), validate the encoding, ensuring we 
never end-up with an unknown one.
 2016-11-04 09:18:04 +01:00
Alexandre Ratchov 4d6d7700a4 Make sio_getpar() on OSS/FreeBSD return the device block size/count 
instead of saved ones. Fixes busy loops caused by poll(2) returning
POLLOUT after the program has filled its play buffer.
 2016-11-04 08:05:47 +01:00
Alexandre Ratchov e867d773fa Tweak spacing of sio_oss.c to look more like other files. 2016-11-03 08:09:11 +01:00

Alexandre Ratchov 2a451f9623 Fix many typos, from Michael W. Bombardieri <mb at ii.net>, thanks 2016-09-27 14:18:43 +02:00
Alexandre Ratchov 7ddb1a5fe5 Don't rely on the resampling code to calculate the number of samples 
to process, as it may produce one extra sample (to handle accumulation
of fractional samples), which would cause access to one sample past
the end of the buffer and crash aucat. Fix this by limiting the number
of samples processed to a single block.

Found by and help from Michael W. Bombardieri <mb at ii.net>. Thanks.

Alexandre Ratchov 00ffc8f5ab Add resamp_getcnt() routine to calculate the exact number of samples 
that would be consumed and produced by the sampler rate converter. Use
it to avoid partial samples that are not properly handled. Fixes
last samples of certain files causing aucat to abort.

intermediate conversion to 2400-th of second.
 2016-05-31 11:24:42 +02:00
Alexandre Ratchov 0798868306 To store MMC position, use samples (at device rate) as time units 
instead of 2400-ths of second. No behaviour change.
 2016-05-31 10:37:17 +02:00
