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. Jan Jan Ekström (3): avutil/{avstring,bprint}: add XML attribute value escape modes 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 Changelog | 1 + doc/general_contents.texi | 1 + fftools/ffprobe.c | 32 +++---- libavcodec/Makefile | 1 + libavcodec/allcodecs.c | 1 + libavcodec/ttmlenc.c | 179 +++++++++++++++++++++++++++++++++++++ libavcodec/version.h | 4 +- libavformat/Makefile | 1 + libavformat/allformats.c | 1 + libavformat/ttmlenc.c | 166 ++++++++++++++++++++++++++++++++++ libavformat/version.h | 4 +- libavutil/avstring.h | 9 +- libavutil/bprint.c | 41 +++++++++ tests/fate/subtitles.mak | 3 + tests/ref/fate/ffprobe_xml | 2 +- tests/ref/fate/sub-ttmlenc | 122 +++++++++++++++++++++++++ tools/ffescape.c | 9 +- 17 files changed, 545 insertions(+), 32 deletions(-) create mode 100644 libavcodec/ttmlenc.c create mode 100644 libavformat/ttmlenc.c create mode 100644 tests/ref/fate/sub-ttmlenc
