- subpicture_cache_destroy() set cache pointer to NULL
- CopyPictureToVAImage() invalidate image members

It is possible for the cache_counter to reach its maximum value. In that case abort().

Turns out vout_Close() does the same except for the vout_control_WaitEmpty().
The vout_control_WaitEmpty() is not needed according to Laurent Ailmar.

Wait till the stop command has been processed by the thread before continuing.

If the decoder fifo is full (growing to large), then instead of flushing and
producing a big artefact in the stream, just drop one buffer. This still limits
the size of the fifo, but does not produce a big artefact as the original code.

Also make the size configurable with a commandline option.

Make sure that when the VAAPI-XCB video output has been started no other picture chroma,
will be accepted. The punishment for not doing this is random crashes, since surfaces are
shared between display pictures and the decoding thread. The picture is the owner of the
surface. If not honoring this, then the decoder might write into surfaces being displayed.
This will result in random crashes since surface memory will be randomly overwritten.

When the vout is not reused the display thread was not properly stopped.

On AMD/ATI the X11 connection is shared between the decoding and displaying thread. Therefor close it only once. This is a workaround and might break NVIDIA GPU's.

Sync surfaces before they are destroyed. The surfaces can be used from more then
one thread context. Therefor make sure that all operations on the surface have
been performed. Then destroy the surface.

Fix version defines for avcodec.

The VA API output on AMD does not like to be recycled. Therefor add
an option to evade the vout recycle path.

The function vlc_va_get_conn() is only used inside va.c.

Conflicts:
	modules/codec/avcodec/video.c
	modules/stream_filter/httplive.c

The function is a bit ugly but it's difficult to do this using
pure arithmetic.

that is to say '--v4l2-chroma=h264'.

DBCS countries assign their currency symbol to '\', ASCII 92. This causes
an unexpected behavior when converting a directory separator on OS/2.
In case of GNU libiconv, it does not treat '\', ASCII 92, as a currency
symbol at all. So let's mimic GNU libiconv.

Close #6403

This patch adds isScrollable() to a control, so that we can distinguish
controls that require mouse wheel (playtree, slider) from those that don't.
In the latter case, we can then forward events to vlc core.

this fixes #6457.

Without this flag, PulseAudio will tweak the buffer parameters, but
will not account for hardware latencies. As a consequence, the live
caching parameter is not really followed - the latency is longer.

Longer latency becomes a big problem when trying to synch with another
live source (such as a V4L2 video capture device). Then audio is too
late and gets discarded or messed up at output.

According POSIX the va_list is defined in stdarg.h
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/stdarg.h.html

On some systems (like uClibc) the detection of vasprintf will fail
unless stdarg.h is included and build will later fail due to a vasprintf
redeclaration.
