# also skipped all show modes and subtitle display related functionality commits

# TODO:
# * Implement CONFIG_SDL to be able to compile without needing SDL at all.
# * Currently, it only supports text subtitles - bitmap subtitles are ignored.
#   Unless one uses a filter to overlay the subtitle.
# * We can not yet visualize audio to video. Provide a filter chain link between
#   audio to video filters to acomplish this.
