Codec options of streams detected during avformat_find_stream_info are not set
therefore without this patch we initialize the encoders with decoder info
based on decoders without options.

This cause problems for probed DVB teletext streams where
avctx->subtitle_header depend on the txt_format setting.

character sets implemented as defined in https://en.wikipedia.org/wiki/EIA-608#Characters

control codes in a cc stream can be repeated, and must be ignored.
however, repeated characters must not be ignored. the code attempted to
wipe prev_cmd in handle_char to allow repeated characters to be
processed, but prev_cmd would previously get reset _after_ handle_char()

i also moved the prev_cmd reset out from handle_char() so it can be
re-used for special character sets, which _must_ be ignored when
repeated.

Use with -use_localtime, and set -hls_segment_filename to a path which
contains a subdirectory i.e. /some/path/%Y%m%d/%Y%m%dT%H%M%S-%s.ts
This will mkdir the %Y%m%d-part of the path if it does not already
exist.
In addition, each filename in the playlist output will be prefixed with
this subdirectory (if playlist and segment shares the same base path).
