[FFmpeg-devel] [PATCH 0/2] 3GPP TS 26.245 Timed Text Encoder.

This patch series introduces support for encoding subtitles as 3GPP
timed text into mp4/mov containers. As with the decoder, there's no
styling support currently.

Note that this feature requires a change to the actual muxer to
handle the insertion of empty packets to signify the end of a subtitle
duration.

Also note that one of the most common use-cases (remuxing from mkv to
mp4) will not work yet, as the subtitle duration is put in the
convergence_duration by the mkv demuxer.

Philip Langdale (2):
  movtextenc: 3GPP TS 26.245 Timed Text Encoder.
  movenc: Handle need for extra packets to express subtitle duration.
