Not sure if I should be posting here, privately, or do the user list
since it is an unaccepted patch... This patch applies cleanly to ffmpeg
git of that day, and with minor adjustment to current git, but either
crashes the same for me right away. Here is the back trace from gdb:

The command (I've tried all sorts of combinations. If I don't provide a
subtitle stream, it does not crash. Otherwise it does. Unpatched can
generate a webvtt from the subtitle stream without crashing.)
ffmpeg -loglevel debug -f lavfi -i movie=out.ts\[out0+subcc\] -f hls

-hls_subtitle_path /var/www/html/stream/kota/ -y
