[FFmpeg-devel] [PATCH 0/4] Implement timing-less srt encoder/decoder

[Philip Langdale]

In the last discussion no how to fix extraction of text subtitles
from matroska containers, we concluded that it was generally
desirable to have a subrip decoder that didn't rely on in-band
timing, and that this would be the right decoder to map to
matroska text subtitles.

This patch accordingly introduces that decoder, and a matching
encoder (currently unused), as well as switching matroska to
decoding S_TEXT/UTF-8 with the new decoder.

I also threw in a fix for the movtext decoder after noticing
a bug while transcoding to mkv.

Philip Langdale (4):
  srtdec: Add timing-less "subrip" decoder.
  matroska: Mark S_TEXT/UTF-8 as Subrip encoded subtitles.
  srtenc: Add timing-less "subrip" encoder.
  movtextdec: Don't emit errors for normal duration-end packets.
