Comment (by mythtv@…):
I'm trying to figure out the best way to provide a sample. I have a
recording of "Anacondas: Trail of Blood" that exhibits the problem. For
example, there's a part that says "[metal rattling]" that appears and
doesn't go away for about 20-30 seconds. The appears that only reason it
goes away is because it is swapped with the next caption. The entire clip
is 4.4GB, so I obviously can't post it somewhere.
I just did some quick searching and now realize I may have mislabeled
this. I was under the (false) impression that teletext and closed
captioning were the same thing, but it looks like teletext is actually a
European standard for PAL video streams while closed captioning is used in
North America. This ticket is actually referring to closed captioning in a
NTSC video stream.
Do you know of a way to re-encode the video stream and maintain that data?
I found some information on the wiki that showed how to use CCExtractor to
extract the closed captions to a text file. I did this and found the
following entries:
00:09:27,567 --> 00:09:30,201
[metal rattling]
00:09:57,363 --> 00:09:59,664
[soft growling]
I assume this indicates the closed captioning is supposed to display for
about three seconds, but it is actually displayed for about 30 seconds
until the following subtitle is displayed. Let me know what else I can
provide.
