This refactors the tolower/toupper code to use standards-conformant logic, and also adds some helpful utility functions. Regular tolower/toupper must be supplied a value that can be represented as `unsigned char`, but the std:: functions are a bit more robust.
This is a follow-up to #2390. Retail used a weird hybrid approach where internal strings were translated but external strings were not. This restores that behavior by adding another language, LCL_RETAIL_HYBRID, which is the default. The game can still be run in completely untranslated or completely translated mode.
All three modes have been tested and translate strings, or not, as expected. The `$Use tabled strings for the default language:` flag has also been tested and still works.
Since the original release of FS2, internal strings have been translated to their English entries in strings.tbl but external strings have not been translated to their English entries in tstrings.tbl. It appears that string translation was universal until it was disabled via a hack, probably due to FRED idiosyncrasies (see comment in `fred_init()`), and then not re-enabled for release. PR #2343 re-enabled it, but this turned out to have undesirable side-effects since many mods used incorrect XSTR indexes for external strings.
This PR restores the previous behavior and also cleanly separates localization into translated and untranslated modes. FRED will always run in untranslated mode. FSO will run in translated mode for all languages except English, where it will run in untranslated mode UNLESS the new option `$Use tabled strings for the default language` is enabled in game_settings.tbl.
Travis CI recently added support for running builds in Windows. This
adds support for testing compilation on Windows using that feature.
The newer version of Visual Studio and MinGW required some code changes
and an update of Google Test which is included in this commit.
This changes the FFmpeg code to not use av_seek_frame anymore if looping
is not required. This fixes an issue when playing MVE movies since that
format does not support seeking.
This fixes#1828.
This adds a playback property for making the movie loop to the start
when the end is reached. The way this is done is by simply keeping the
decoder running even if the end of the movie is reached. Then the movie
is reset to the beginning and decoding continues. The player detects
this reset by examining the frame times which keeps the playback
constant.
This also includes support for this in the movie scripting API.
This adds an API for the scripting system which allows it to load and
display movie files using the standard movie player code which includes
multi-threaded frame decoding.
This allows to directly display RGB(A) movies without transcoding them
to YUV first. This allows the movie player to support APNG files (which
are supported natively by FFmpeg) with an alpha channel and without
converting them to YUV first.
This allows to use external subtile files (currently only SRT is
configured) for providing subtitles for movie files. This should be more
universal since it also supports container formats with no support for
subtitle streams.
To use this code the srt file needs to be named
"<movie name>-<language code>.srt" where the language code is the file
extension name specified in the localization table. For english the
"-..." part can be omitted.
This adds support for displaying subtitles embedded in movie files. This
supports files with multiple subtitle streams where each stream contains
the subtitles for one language. When the movie file is opened, the
stream for the currently active language will be used and displayed.
This resolves one of the points mentioned in #1522.
This also depends on PR #1484.
It turns out that FFmpeg is actually able to decode the Interplay MVE
movies so we can drop the old MVE code and just use FFMpeg and the new
video player interface for that.
