There are several pending issues with this patch series that I am not yet
satisfied with.

First, lavd/lavfi is maintained by Stefano; he seems busy these days.

Second, there is the issue of the name of the codec and its id. I called it
CEA-708, but Anshul says it should be CEA-608; unfortunately, I do not find
any trace of such a thing, there is only EIA-608. According to wikipedia and
Reimar, CEA-708 would be a combination of EIA-608 and some more data; but
maybe that is already what is coded by AV_CODEC_ID_EIA_608.

Third, there is the issue of testing. Right now, this patch allows to just
dump binary data, and an ASCII/hex dump of that shows promising tidbits of
text, but I would be much more comfortable if someone would produce code
that would allow to do something actually useful with it.

For the last point, I believe Anshul can be of some help: you gave a small
source code that would save the same binary data in a file. Can you explain
what you do exactly with that file afterwards? I do not suppose you can just
give it as is to ccextractor.
