[FFmpeg-devel] [PATCH v4 0/4] Initial implementation of TTML encoding/muxing

[Jan Ekström]

I've intentionally kept this initial version simple (no styling etc) to focus
on the basics. As this goes through review, additional features can be added
(I had initial PoC for styling implemented some time around previous VDD), and
there is another patch set in my queue which would then add support for muxing
TTML into MP4.

Changes from the third version:
  - Updated the result of the ffprobe XML output test, as I missed it when
    updating the exact escape mode utilized.

  ffprobe: switch to av_bprint_escape for XML escaping
  {avcodec,avformat}: add TTML encoder and muxer

Stefano Sabatini (1):
  avutil/{avstring,bprint}: add XML escaping from ffprobe to avutil
