Ryan C. Gordon 21c7fe0060 windows: directsound should also map audio device GUIDs to proper names.
Moved this code from winmm into core so both can use it.

DirectSound (at least on Win10) also returns truncated device names, even
though it's handed in as a string pointer and not a static-sized buffer.  :/

Ryan C. Gordon 7a8e4cb019 directsound: recalculate audiospec size before creating secondary buffer.
I think this was a bug before? Maybe I'm misunderstanding this, but it looks
like it was working because we allocate room for 8 chunks...

Easier to check when it's NULL instead of a list of known internal functions.

Ryan C. Gordon 7315390171 audio: Implemented buffer queueing for capture devices (SDL_DequeueAudio()). 2016-08-06 02:47:27 -04:00
Ryan C. Gordon e7347a4027 audio: SDL_ClearQueuedAudio() should free everything but two packets.
Otherwise, if you had a massive, one-time queue buildup, the memory from that
remains allocated until you close the device. Also, if you are just using a
reasonable amount of space, this would previously cause you to reallocate it
over and over instead of keeping a little bit of memory around.

Ryan C. Gordon 761a79788c audio: changed some SDL_memset() calls to SDL_zero(), other minor corrections. 2016-08-05 01:59:06 -04:00
Ryan C. Gordon 979de761c9 audio: Removed internal SDL_audiomem.h and macros.
I think this was important for SDL 1.2 because some targets needed
special device memory for DMA buffers or locked memory buffers for use in
hardware interrupts or something, but since it just defines to SDL_malloc
and SDL_free now, I took it out for clarity's sake.

Ryan C. Gordon 9b64772775 audio: Clean up some CloseDevice() interface details.
- It's now always called if device->hidden isn't NULL, even if OpenDevice()
  failed halfway through. This lets implementation code not have to clean up
  itself on every possible failure point; just return an error and SDL will
  handle it for you.

- Implementations can assume this->hidden != NULL and not check for it.

- implementations don't have to set this->hidden = NULL when done, because
  the caller is always about to free(this).

- Don't reset other fields that are in a block of memory about to be free()'d.

- Implementations all now free things like internal mix buffers last, after
  closing devices and such, to guarantee they definitely aren't in use anymore
  at the point of deallocation.

Ryan C. Gordon 30a9139bc3 arts: backed out audio capture support.
Turns out that libartsc isn't thread-safe, so if we run a capture and playback
device at the same time, it often crashes in arts's internal event loop.

We could throw mutexes around the read/write calls, but these are meant to
block, so one device could cause serious latency and stutter in the other.

Since this audio target isn't in high-demand (Ubuntu hasn't offered a libartsc
package for years), I'm just backing out the capture support. If someone needs
it, they can pull it out of the revision history.

Ryan C. Gordon d30a2f5ad8 bsdaudio: this appears to be using the wrong variable...?
(We probably never noticed because this is meant to block until it fully
writes a buffer, and would only trigger an issue if we had a short write
that wasn't otherwise an error condition.)

Ryan C. Gordon 754efd43f4 alsa: Cleaned up the 5.1 swizzle mess a little.
Shouldn't this be something ALSA handles for us with channel maps, so we can
just delete this code?

Ryan C. Gordon c61675dc5d threads: Move SDL's own thread creation to a new internal API.
This allows us to set an explicit stack size (overriding the system default
and the global hint an app might have set), and remove all the macro salsa
for dealing with _beginthreadex and such, as internal threads always set those
to NULL anyhow.

I've taken some guesses on reasonable (and tiny!) stack sizes for our
internal threads, but some of these might turn out to be too small in
practice and need an increase. Most of them are simple functions, though.

Ryan C. Gordon a581346fae alsa: Make device enumeration robust against weird results with NULL strings. 2016-04-04 22:49:13 -04:00
Ryan C. Gordon 1e8df9cd60 alsa: Implemented basic device detection.
This is kind of nasty, because ALSA reports dozens of "devices" that aren't
really things you'd ever want, or things that should be listed this way, but
the default path still works as before, and it at least allows these devices
to be available to apps.

This does not handle hotplugging yet. You get a device list at init time
and that's it.
