Subject: New QNX patches
Please apply patch qnx4.diff, which is attached. What has been done:
1)Added back OpenGL ES renderer for QNX target. Added few corrections to
OpenGL ES renderer to let it work under QNX. OpenGL ES renderer do not
support textures under QNX, so I think some additional work must be done.
2) Added GL_OES_query_matrix extension to SDL_opengles.h header file, which
required by OpenGL ES 1.1 specification.
3) Added attribute clearing at the entrance of function
SDL_GL_GetAttribure(). Added error checking into the function
SDL_GL_GetAttribure(), because some attributes can't be obtained in OpenGL
ES 1.0.
4) Porting testdyngles to OpenGL ES 1.0 (1.1 has glColor4ub() and
glColor4f() functions, but 1.0 has glColor4f() only).
5) Added error checking after obtaining attributes using
SDL_GL_GetAttribute() function to the testgl2 and testgles.
6) Small correction to testmultiaudio with printing errors.
7) Added software and accelerated OpenGL ES 1.0 support into the QNX GF
driver.
Please remove ./src/audio/nto directory - it will not be used anymore.
Please create ./src/audio/qsa directory and add content of the archive
qsa.tar.gz into this directory. I rewrote some sound code, added support for
multiple audio cards, enumeration, etc. Added initial support for capture.
As far as I can understand SDL 1.3 is not supporting audio capture right now
? Sam, Am I right ? Or audio capture must be supported through the
PlayDevice routine ?
And last, please put file SDL_gf_opengles.c to the ./src/video/qnxgf
directory. It is OpenGL ES 1.1 emulation layer for some functions, which are
not supported by OpenGL ES 1.0.

Subject: [SDL] Possible bug, paused audio playing garbage
On my WinCE device a paused audio device plays random garbage.
This might also be the issue in the thread "sound cracks with SDL_mixer
and AUDIO_S16LSB"
I don't have that much knowledge of the SDL audio part, but the attached
patch fixes it for me, and collapses two redundant ifs.
I'm not sure if this is the correct way to fix this.
Shouldn't the complete stream conversion part of the RunAudio loop be
dependent on the paused property of the device? (not only the call to
(*fill)(udata, istream, istream_len).
Anyways. Would be great if the patch or a fix could find its way to SVN ;-)
Cheers
Stefan

Description From Michael Stone 2008-09-25 19:27:29 (-) [reply]
To determine whether a pid is occupied with the kill(pid, 0) idiom, you have to
test
#include <signal.h>
#include <errno.h>
kill(pid, 0) < 0 && errno == ESRCH
not just
#include <signal.h>
kill(pid, 0) < 0
otherwise you get incorrect results when pid is running as a different user
(causing kill(pid, 0) to return -1 + EPERM).
src/audio/alsa/SDL_alsa_audio.c is certainly affected by this bug in both
1.2.13 and 1.3-trunk. It probably occurs in other places as well.

We should probably give options to drop resamplers by channels, too, for
developers that know they'll never need more than stereo, etc.

* Some math functions become intrinsic in release mode, so we need to
convert all the math functions into SDL math functions, like we did
with the stdlib functions.
* Constant initializers of 8-bit values become calls to memset() in
release mode, but memset() itself is an intrinsic when explicitly
called. So we'll just explicitly call memset() in those cases.

Subject: Fusionsound audio driver
attached is a diff containing a audio driver for the FusionSound
library. This sound library is closely related to DirectFB and uses the
same transport (fusion) as DirectFB when running applications "remote",
i.e. over the network. As such, it natively redirects sound where
DirectFB redirects video. This may be handy for everyone using SDL over
DirectFB.

If a driver can definitely see available devices, it is chosen. Otherwise,
we'll take the first driver that initializes but saw no devices...this might
be because it can't enumerate them, or there really aren't any available.
This prevents the dsp driver from hogging control when there are no /dev/dsp*
nodes (for example, on a Linux box with ALSA and no OSS emulation).

The API specifies that SDL_OpenAudio() will fill out the 'desired' audio spec
with the correct samples and size set by the driver. This value is important
since it may be used by applications that size audio buffers, etc.
However, we want to allow advanced applications to call SDL_OpenAudioDevice()
which gets passed a const 'desired' parameter, and have the correct data filled
into the 'obtained' parameter, possibly allowing or not allowing format changes.
So... 'obtained' becomes the audio format the user callback is expected to use,
and we add flags to allow the application to specify which format changes are
allowed.
Note: We really need to add a way to query the 'obtained' audio spec.

Subject: Fix to compile SDL-1.2 SVN on OS X Leopard
I found I needed to add a conditional check for Leopard to compile
cleanly on 1.2-SVN (20071114):
#include <AudioUnit/AudioUnit.h>
#ifdef AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER
#include <AudioUnit/AUNTComponent.h>
#endif
where there is now just:
#include <AudioUnit/AudioUnit.h>

I've changed it to respect the environment variable and do it for all devices
now.)

bitshift an Sint64, but it can't find this function since we don't use the
C runtime on Windows.
Division doesn't have this problem, though. Strange.
