13016	Missing Teletext Subtitles in Recordings	angela.schmid@…	Peter Bennett	"I notice a lot of missing CC text from Teletext Subtitles in DVB-C recordings independent of the recorded channel.

VLC, ccextractor, FFmpeg 3.2.4 show all CC text correct.
MythTV player and mythccextractor miss almost every second/third CC text. In a recording Myth found only 732 of 1651 total.

Inspecting the ccextractor generated srt file doesn’t show any timing problems, which could be misinterpreted by MythTV.

I tried VBI debugging, but no CC text was logged.

Also no “subtl timecode” from libs/libmythtv/avformatdecoder.cpp AvFormatDecoder::ProcessSubtitlePacket although proper debugging options were set.

Appreciate any pointers where to add some debugging to help.
