[Buildroot] [NEXT v2 1/7] libpjsip: remove disable-ext-sound option

[Adam Duskett]

The configure option --disable-ext-sound currently isn't a valid option
in libpjsip. Originally it was used to prevent portaudio from building
in the third_party directory, however, portaudio no longer exists in that
directory.

[Buildroot] [NEXT v2 3/7] libpjsip: enable portaudio support

[Adam Duskett]

If portaudio is selected, libpjsip should depend on it.
Specifying --with-external-pa was originally used to prevent libpjsip
from building the portaudio library in the third_party directory, however,
portaudio no longer exists in the third_party directory.  This option now
is used to force libpjsip to check for external portaudio headers.

[Buildroot] [NEXT v2 6/7] libpjsip: add dependency-less codecs

[Adam Duskett]

libpjsip has several codecs, all of which can be disabled or enabled
individually. A few reasons for adding each codec as an individual choice
are:

1) Many products might not want some of the more obscure codecs such as 
   ILBC or L16.

2) libpjsip has functions that will enumerate all the codecs that were built.
   If all the codecs where built, this would require a developer to have to
   parse out the codecs they don't want.
   
As such, turn libpjsip into a menuconfig and add each supported codec as an
individual choice.

Start with the codecs that are built into libpjsip and have no external
dependencies.  These codecs are:
- G.711
- G.722
- G.722.1
- iLBC
- L16

Why? This seems completely backward with the typical Buildroot
practices.

 I tried all combinations of the different sound options, and these are my
conclusions:

1. --enable-sound and --disable-sound both work as expected and have the effect
of enabling alsa support. It has no other effect. So, I think patch 2/7 should
pass --enable-sound if alsa is enabled, and --disable-sound if not.

2. --disable-ext-sound has no effect at all. However, since the option still
exists, and to be future-safe in case that it may make a difference, I would not
remove the option (just like you don't remove --disable-oss).

3. --with-external-pa also has no effect on the build result, other than giving
the warning
<command-line>:0:0: warning: "PJMEDIA_AUDIO_DEV_HAS_PORTAUDIO" redefined

 Indeed, os-auto.mk will set this define twice: it is set to 1 due to
--with-external-pa, and then set to 0 due to --enable-sound
(AC_PJMEDIA_SND=alsa) or --disable-sound (AC_PJMEDIA_SND=null). The 0 "wins" so
portaudio is not used at all.

 Therefore, I'd remove patch 3/7 entirely and instead add an explicit
--without-external-pa.


 Regards,
 Arnout

 This bit should have a bit more explanation in the commit message. Like:

--enable-video has no effect at all on Linux (only on Android and darwin).
--disable-video has the effect of disabling SDL, ffmpeg, v4l2, openh264 and
libyuv. Since all of these are enabled/disabled explicitly already, there is no
need to specify --disable-video. To do so correctly is non-trivial when we want
to support e.g. ffmpeg OR v4l2.

 Here, I would also give the full explanation in the commit message:

When --enable-ffmpeg is given, the code to enable ffmpeg is not executed. Also,
when cross-compiling and no --with-ffmpeg option is given, ffmpeg is disbled.
Therefore, a --with-ffmpeg option needs to be given. Normally it is used to pass
the path to the directory where ffmpeg is installed, but since we install it
directly under sysroot we can pass it empty.

 --with-ffmpeg without anything works as well, i.e.:

LIBPJSIP_CONF_OPTS += --with-ffmpeg
