Adding Closed caption

[anshul1912]

Hi

I implemented closed caption here, if you want you can cherry pick from my code and merge it to your base

Many thanks for putting the effort into caption support! Do you have any info on how to use this? It seems the nut mux has issues in the caption-enabled version. I get "[nut @ 0x1229da0] No codec tag defined for stream 2" (and no data output) when using the following command:

./bmdcapture -M2a00M -C0 -Fnut -m8 -c2 -A2 -V4 -o strict=experimental:syncpoints=none -f pipe:1 | head -c 1000 | hexdump

This same command works fine using lu-zero/bmdtools without the caption support.

I hadn't time to integrate it properly sadly =/
