If the decoder returns a new size via the crop rect, but hasn't
explicitly indicated a plane height (via the nSliceHeight parameter),
keep the frame height as plane height instead.

Also do the same check for stride vs width. The decoders that had
problems that the nSliceHeight fixes do set nStride properly, so
that part won't be needed there, but might be needed on some
platform.

It is an OpenDML extension that contains the aspect ratio (it closes #6777).

This way, the official atomic functions will be used when available,
rather than VLC's own implementation.

This commit also enables proper atomic operations on some platforms
or with some toolchains. __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 is not
defined on some platforms such as ARM Linux, nor by other compilers
than GCC such as LLVM/clang. Then atomic operations wrongly fell
back to the lame mutex-based implementation.

This will break support for some old compilers and old or irrelevant
instruction set architectures. They would need to provide replacement
for the Intel-originated __sync_* builtin functions.

Since this constitutes mostly of macros and type definitions, it would
not fit too well in compat/. Most of the code would end up in
<vlc_fixups.h> rather than compat/. Moreover, I doubt that those
functions would be detected properly with AC_CHECK_FUNCS or
AC_REPLACE_FUNCS.

Anyway, VLC already has a separate header, and it will need to keep it
until <stdatomic.h> can be relied upon... many years from now.

This is now the same as was already implemented in the
set_relative_playlist_position_and_play() method.

macosx: improve the handling of broken prefs and make sure that the user is unable to re-break them without using the command-line or a text editor

This reverts commit 8bc285bd.

The original purpose for this code is fixed somewhere else today.

close #6769

In particular, V4L is (usually) an access_demux rather than an access.

Format the text. If it is identical and all parameters are unchanged,
there is no need to update - even if the format contains a $ sign.

A slave input should be used for audio, probably ALSA or Pulse.

Improve scene video filter to write pictures in a separate thread.

macosx: trust the user that s/he knows what s/he's doing when opening a VIDEO_TS folder (close #6108)

in other words, accept folders which aren't named 'VIDEO_TS'

It probably wouldn't hurt to provide helpers for mouse events.

This is similar to hotkeys. There is no need for a hand-over thread.

Thanks to Rémi for the help

If a thread can be cancelled, it can be joined.
