reduces the need of ifdefs when adding ch_layout support

this provides an implementation for Hierarchical State Machine in QML/JS.

why not qt implementation:

This avoid requiring an extra dependency

QtQml.StateMachine implementation is quite buggy: no being able to pass complex
types through guard and actions is really limiting.

Qt SCXML implementation requires another language for declaring FSM and would
be tedious to integrate with meson.

what's missing:

* no timeout transition: right now you can start/stop a Timer instance in your
  enter/exit callbacks, it's more verbose but it felt unnecessary to add a
  special implementation for it.

Not only the length, but position, time and normal_time.

The times event is now sent from only one place, in es_out.c

But not for slaves since they don't have an input_item_t.

Helper that fetches the duration from the item in case of demux failure.

channels and channel_layout has been deprecated in FFMPEG 5.1 and will be removed eventually

also always create the mapping, as ch_layout is always there

conditioned to avcodec version where is it added

Ilkka Ollakka authored 1 year ago and Jean-Baptiste Kempf committed 1 year ago

Allows to have less conditions in code when adding new ch_layout use

with previous code, it only handled 6 channels

Previously it muxed channels in incorrect order.

Remove unneeded arrays and use already defined one in demuxer-side.

WAVE-mapping don't match AOUT_CHAN mapping, so simpler to use
AOUT_CHAN_* mapping than trying to check how get reordering work with
WAVE_*.

Notably:
- Fixed various segfaults and buffer overruns (CVE-2023-2804)
- Fixed an issue that caused the C Huffman encoder (which is not used by
  default on x86 and Arm CPUs) to read from uninitialized memory when
  attempting to transform a specially-crafted malformed arithmetic-coded
  JPEG source image into a baseline Huffman-coded JPEG destination image.

Release notes:
https://github.com/libjpeg-turbo/libjpeg-turbo/releases/tag/3.0.0

Fixes a warning when using the integer variable to store the HINSTANCE.

This code only makes sense when calling ShellExecuteW(), so we move the
code in the same ifdef section.

We build for Win7+, the function is always there.

And no need to define PROCESS_DEP_ENABLE. It's available in mingw-w64 since 4.0.

Or rather vlc_cxx_helpers.hpp earlier which often includes winsock.

Only needed once for Windows and once for OS/2.

Only needed a couple of times for Windows and once for OS/2.

vlc_charset includes windows.h which is supposed to be included *after*
winsock.h/winsock2.h.

vlc_charset includes windows.h which is supposed to be included *after*
winsock.h/winsock2.h.

_DECL_DLLMAIN is needed to get the signature of DllMain. But depending
whether windows.h is included the signature differs (WINAPI, HANDLE, etc).
This is only the case in mingw-w64. In the Windows SDK there's only the
definition without the fancy types.

We need to include process.h before windows.h so we have the same definition
as the Windows SDK.

It is sometimes included without vlc_common.h.

This would be needed if we were using the registry.

Code doing Windows specific calls need to do the include themselves.

We should not always include windows.h because it should not be included before
winsock headers.

vlc_fixups.h may include some header that define different things depending
on the WINAPI_FAMILY (processthreadsapi).

We don't use any VLC code in there, only a few standard headers.

This fixes synchronization issues when 2 demuxers have a different time
base (like .ts + .srt for example).
