Looking at Wikipedia, MPEG4 supports "MPEG4 Timed Text" (aka subtitles)
embedded in the stream. ffmpeg should be able to combine the reference
video and some SRT-formatted text events using something like:
ffmpeg -i Original.mp4 -i Events.src -slang foo -acodec copy -scodec copy \
output.mp4 -newsusbtitle
(where -slang *foo* is an ISO 639-2 code. 'zxx' (no linguistic content,
not applicable) may be a good choice).
