[Bug]: sdl2 audio drivers missing? #10072

Closed Randrianasulu closed 2 years ago

Randrianasulu commented 2 years ago

Problem description

I try to learn a bit about audio programming with sdl2

I copied code from https://gist.github.com/armornick/3447121 it compiles but gives me error on sdl_init. I added sdl function listing audio drivers and it returns

$ gcc -o playwav-2 playwav-2.c -lSDL2 $ ./playwav-2 Using default wav file: "1.wav" Audio driver 0: pulseaudio Audio driver 1: disk Audio driver 2: dummy SDL_Init(SDL_INIT_AUDIO) < 0, err = Could not connect to PulseAudio

i see sdl itself have opensl es and android audio drivers. https://github.com/libsdl-org/SDL/tree/main/src/audio

can they be enabled for termux?

What steps will reproduce the bug?

compile and run wav-playing sdl2 code in termux, without pulseaudio running

What is the expected behavior?

example plays sound

Not reproducible for me (Android 8.1.0 aarch64 asus ASUS_X01AD). The example just exits normally. What is shown in your logcat output?

Randrianasulu commented 2 years ago

ah, sorry - it works if I start pulseaudio manually. (was confused by termux vs termux-x11)

Randrianasulu commented 2 years ago

so, i hacked configure.ac from sdl 2.0.20 (added "|linux" for existing android audio case), more audio drivers appeared in summary, build was ok, but link is not:


LTLINK build/libSDL2.la

Randrianasulu commented 2 years ago

also, there is second, more convient to use sdl2 example: https://gist.github.com/LaughingSun

(no need to recompile for new sound file - i made wav file by running mplayer with -ao pcm:waveheader)

Randrianasulu commented 2 years ago

so, new llvm 14 broke even compilation of those audio drivers.

i looked up error text, found https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262634

removed Werror=no-declaration-after-statement from Makefile (put there by configure generated from configure.ac), and back to linking error.

CMake build can't even configure itself (complain about cpufeatures.c missing) .. And I can't see way to enable Android audio outputs via options in ccmake

xtkoba commented 2 years ago

Actually this is already resolved: https://github.com/termux/termux-packages/issues/10072#issuecomment-1102306997. I do not know why PulseAudio did not start automatically, but that is another issue. And the rest is completely off-topic.
