[ptxdist] [PATCH 0/2] new package libsamplerate, used by alsaloop from alsa-utils

[Andreas Pretzsch]

Add package libsamplerate, an audio sample rate converter library.

Without it, the optional alsaloop program from alsa-utils will bail out with
"No libsamplerate support.", as it defaults to sincfastest from libsamplerate
(equal to "-A 3"). While this can be bypassed by calling alsaloop with an
(undocumented) "-A -1", just add libsamplerate and autoselect it for alsaloop.

Andreas Pretzsch (2):
  libsamplerate: add package
  package alsa-utils: alsaloop requires libsamplerate, so autoselect it

This won't work. You're not getting the correct build-time dependencies
like this. Correct is this:

config ALSA_UTILS
	[...]
	select LIBSAMPLERATE if ALSA_UTILS_ALSAMIXER
	[...]

Finally took the time to look into this.
Compiled and tested without sndfile and fftw, with sndfile enabled, and
with sndfile and fftw enabled.
Result: The autodetect of libsamplerate configure works well here.

All we have here from configure is:
  --disable-fftw          disable usage of FFTW
  --disable-sndfile       disable support for sndfile
[...]
  SNDFILE_CFLAGS
              C compiler flags for SNDFILE, overriding pkg-config
  SNDFILE_LIBS
              linker flags for SNDFILE, overriding pkg-config
  FFTW3_CFLAGS
              C compiler flags for FFTW3, overriding pkg-config
  FFTW3_LIBS  linker flags for FFTW3, overriding pkg-config


build with both disabled:
[...]
checking for SNDFILE... no
checking for FFTW3... no
[...]
  Extra tools required for testing and examples :
    Use FFTW : .................... no
    Have libsndfile : ............. no
[...]

build with sndfile enabled:
[...]
checking for SNDFILE... yes
checking for FFTW3... no
[...]
  Extra tools required for testing and examples :
    Use FFTW : .................... no
    Have libsndfile : ............. yes
[...]

build with sndfile and fftw enabled:
[...]
checking for SNDFILE... yes
checking for FFTW3... yes
[...]
  Extra tools required for testing and examples :
    Use FFTW : .................... yes
    Have libsndfile : ............. yes
[...]

Now, libsamplerate-0.1.8/INSTALL states that sndfile are fftw are only
required for some examples and some tests. None of which are installed
here. By sure some sweet pieces of code, for everyone interessted in
using libsamplerate in an own project. But at least for my usage
(alsaloop), this is not the case.

Same applies for fixing pkg-config troubles by passing flags.

Last, forcefully disabling one or both with a configure option - despite
being enabled in ptxconfig and hence found - won't buy us much.
Just, libsamplerate won't link against them.
Not worth a ptx option, in my opinion.

Bottom line: I don't see any sensible defaults resp. options here.


One thing that _might_ be worth looking into is the clipping option
"--disable-cpu-clip". If enabled, src_float_to_short_array() omits
overflow/underflow checks. Might be a nice optimization.
Just, the autodetect of configure for this runs some test code on the
build host. Which here on my machine (x86_64 (Intel Core2)) results in
no, so it is implicitly disabled. No idea for other build hosts.
But point is, the check runs not on the target, so it might end in a
false-positive. And there is no enable-counterpart of this option (resp.
won't change anything, just tested). And I'm not in the mood to hack
this in...

Bottom line: Always disable it, to be safe, without option.


Final result: I'll send a v2 with:
LIBSAMPLERATE_CONF_OPT  := \
    $(CROSS_AUTOCONF_USR) \
    --disable-cpu-clip

Anything else can be added by those who need it.

[ptxdist] [PATCH v2] alsa-utils: autoselect libsamplerate for alsaloop

[Andreas Pretzsch]

alsaloop will bail out with "No libsamplerate support." when not
linked against libsamplerate, as it defaults to sincfastest from
libsamplerate (equal to "-A 3").

While this can be bypassed with an (undocumented) "-A -1", just
autoselect libsamplerate for alsaloop.
