 Other H.264 encoders have ATSC A/53 CC copy from source support which was
 added with this commit:
 https://github.com/FFmpeg/FFmpeg/commit/e06114fed3afa69187b3dfc09a7a1a25cfd558b3

 However the required option -a53cc is not present for the nvenc_h264
 encoder

 Looks like there was a patch submitted to add A/53 to the nvenc encoder
 but not implemented ?
 https://ffmpeg.org/pipermail/ffmpeg-devel/2016-June/194927.html

 Summary of the bug:
 How to reproduce:
 {{{
 ffmpeg -h encoder=nvenc_h264
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
