Closed Captioning contained in MPEG user data fields

[kenny@…]

This is a patch to support closed captioning in MPEG user data fields that start with the bytes 0x05 0x02. It's basically a way to preserve line 21 data that some DVB providers use. This patch provides support for that closed captioning format.

Just compiled it, and good part that something is working, however i'm getting bunch of garbage in addition to CC... (using DVB DN)

Thanks for the testing. It turns out I was doing too much work. In my 0.16 version I had to manually reorder predictive frame data because of the way it was implemented, but 0.20's decoder does that for me.

Here's the revised version of the patch. Let me know how it works.

This one work great for DN, would be nice to put into the trunk now...

(In [11356]) Fixes #2481, by applying patch from kenny at the-b org. This adds decoding of US style EIA-608 captions embedded using the 0x0502 DVB encoding of such captions rather than the newer ATSC standard EIA-608 embedding.

Any chance of merging this into the 0.20 branch?

Thanks.
