Seek external subtitles
If the input is a regular file, gmerlin_avdecoder can scan the directory for matching subtitle files. For a file movie.mpg, possible subtitle files are e.g. movie_english.srt, movie_german.srt. The rule is, that the first part of the filename of the subtitle file must be equal to the movie filename up to the extension. Furthermore, the subtitle filename must have an extension supported by any of the subtitle readers. Subtitle seeking can be disabled, enabled for video files or enabled for all files.
