GCC takes the last -O* option, which defaults to -O0 anyway. With
./configure forcing -O0, there was no way to select a custom
optimization level via external CFLAGS.

Optimizing VLC code for size is probably not such a great idea,
considering that media playback is performance critical. There are
better ways to reduce code size than -Os, e.g. Thumb(2) code on ARM.

And of course, removing unneeded plugins and feature is the best way
to reduce code size.

In many cases, OSS was used when the builder forgot to install the
alsa-lib development headers. This should not be an issue anymore, as
ALSA is now required on Linux by default.

I believe the fallback to OSS from ALSA and PulseAudio is causing more
confusion than it solves problem. Besides, the OSS emulation by ALSA
cannot mix, so OSS is almost completely useless on Linux, unless OSSv4
was specifically installed.

Moreover, Linux distributions have started dropping OSS completely.

This ensures that at least either ALSA or PulseAudio will be compiled
by default (on Linux).

This will be needed if/when we get a PulseAudio input and SD.

Nothing wrong with the commit, but I need to revert it to refactor the

Currently the V4L2 device to be used can only be set via the media URL.
This patch allows the :v4l2-dev option to set the device as well.
Setting the device via the media URL still takes precedence.

This is useful if a program auto-detects the V4L2 device so that the
media URL only needs to contain e.g. the tuner settings.

closes #4721

This plugin had become useless since the removal of the OMAP
framebuffer video output.

This reverts commit 8a1afb86.
Don't define HAVE_LINUX if you don't have it in the first place.
And this does not even respect the configure message rules.

This fixes a memory leak, encoding problems, and complete failure on
non-file inputs.

access_dtv for Android systems.

"podcast-urls" is autosaved in any case.

Bookmark configuration items are not in hotkeys (at least currently),
so this could not work.

and mention subtitles blending in vout

And fix ts/mux_ts modules
