This change introduces a basic encoder for 3GPP Timed Text subtitles, also known as TX3G, Quicktime subtitles, or "movtext" in the existing code. This initial change doesn't attempt to write styling information, and just writes the plain text of the subtitles. I intend to add support for styles eventually, but it's challenging due to a lack of existing players that support them. Note that an additional change is required to the mov/mp4 muxer to write empty subtitle packets to indicate subtitle duration. Signed-off-by: Philip Langdale <philipl@overt.org>
