[FFmpeg-devel] [PATCH] Added Closed caption support for cuviddec for preserving a53 data n GPU decoding

[Dhanish Vijayan]

I used the patch provided here -
https://github.com/tea/FFmpeg/commit/ba3df26047ca2e2c2a79c4cab436ace032c73d57
With this patch I was able to get the Closed caption issue fixed with the
cuvid.

After seeing your message, I am trying to figure out how I can use
the ff_parse_a53_cc for parsing.
The implementation seems to be different, and I am beginner in this. Will
let you know if I can implement the parsing using this function.
