6d7be209c2 Fixed bug 3705 - Add capture support to the sndio backend 
kdrakehp

The attached patch adds capture support to the sndio backend.

The patch also allows the `OpenDevice' function to accept arbitrary device names.

ba66a89116 Fixed bug 3668 - Overflow of SDL_AudioCVT.filters with some downmixes 
Simon Hug

There's a chance that an audio conversion from many channels to a few can use more than 9 audio filters. SDL_AudioCVT has 10 SDL_AudioFilter pointers of which one has to be the terminating NULL pointer. The SDL code has no checks for this limit. If it overflows there can be stack or heap corruption or a call to 0xa.

Attached patch adds a function that checks for this limit and throws an error if it is reached. Also adds some documentation.

Test parameters that trigger this issue:
AUDIO_U16MSB with 224 channels at 46359 Hz
                 V
AUDIO_S16MSB with 6 channels at 27463 Hz

The fuzzer program I uploaded in bug 3667 has more of them.

a60238d3e0 wasapi: properly report init failure if on pre-Vista version of Windows. 
We really should change the Init interface to return 0 on success and -1 on
error, like everything else, to avoid this sort of confusion.

632becceb1 audio: rename bsd target to netbsd. 
Apparently this is no longer a generic BSD audio target, and hasn't been for
years, so rename it for NetBSD.

11c7c95872 coreaudio: we don't need to track number of allocated audio buffers anymore. 
CoreAudio takes care of iterating through the buffers and freeing them now,
so we don't have to manage this ourselves.

1e0aa57252 coreaudio: Better handling of audio buffer queue management. 
We don't fill buffers just to throw them away during shutdown now, we let the
AudioQueue free its own buffers during disposal (which fixes possible warnings
getting printed to stderr by CoreAudio), and we stop the queue after running
any queued audio during shutdown, which prevents dropping the end of the
audio playback if you opened the device with an enormous sample buffer.

Fixes Bugzilla #3555.

3814517cb2 coreaudio: looks like we need more like a 10ms buffer minimum, not 50ms. 2017-05-24 01:28:03 -04:00
Ryan C. Gordon
139f3d0491 coreaudio: dynamically allocate AudioQueueBuffers. 
We need more than two buffers to flip between if they are small, or CoreAudio
won't make any sound; apparently it needs X milliseconds of audio queued when
it needs to play more or it drops any queued buffers. We are currently
guessing 50 milliseconds as a minimum, but there's probably a more proper
way to get the minimum time period from the system.

Fixes Bugzilla #3656.
