Ryan C. Gordon 978df1ad74 disk audio: Implemented "capture" support, cleaned up some things. 2016-08-06 03:39:15 -04:00
Ryan C. Gordon a15b974044 testaudiocapture: use capture device buffer queueing, for better test coverage. 2016-08-06 02:48:00 -04:00
Ryan C. Gordon 7315390171 audio: Implemented buffer queueing for capture devices (SDL_DequeueAudio()). 2016-08-06 02:47:27 -04:00
Ryan C. Gordon 7bfe494c62 testaudiocapture: don't use fullscreen for the window. 2016-08-06 02:45:51 -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 9a33154450 nas: initial shot at audio capture support. Compiles, but not tested. 2016-08-05 04:23:32 -04:00
Ryan C. Gordon 9b2a59ef05 audio: Changed OnlyHasDefaultInputDevice to OnlyHasDefaultCaptureDevice. 2016-08-05 02:04:48 -04:00
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 20cd5e44ce dummy audio: Patched to compile. 2016-08-03 16:54:10 -04:00

Philipp Wiesemann 9f97ee8a85 WinRT: Removed not needed SDL_zerop() after SDL_calloc(). 
SDL_calloc() already sets memory to zero.

Philipp Wiesemann a4abda0b70 Added brackets to function names in header comments so that doxygen links them. 2016-08-03 22:30:31 +02:00
Ryan C. Gordon 17246ba95e dummy audio: Implemented dummy audio capture support. :) 2016-08-03 02:18:47 -04:00
Ryan C. Gordon 9dd8477a21 bsdaudio: first shot at audio capture support! 
(untested, uncompiled...for now.)
 2016-08-03 01:57:41 -04:00
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 ecbd625c4b arts: Patched to (maybe) compile. 2016-08-03 01:53:59 -04:00
Ryan C. Gordon a7dddacd99 arts: implemented audio capture support. 
(completely untested! Not even compiled!!).
 2016-08-03 01:01:44 -04:00
Ryan C. Gordon 38f4b68ca7 alsa: capture devices don't need a mixbuf allocated. 2016-08-03 01:00:30 -04:00
Ryan C. Gordon 3ed9b0f567 testaudiocapture: made test app interactive. 
(hold down mouse/finger to record, then it plays back what it heard. Repeat.)

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?
