Comment:
FFmpeg does not distinguish subtitles from captioning internally.
Therefore, in real life caption may not = subtitles, in FFmpeg the
handling for captions = handling for subtitles.
For example, EIA/CEA-608 has a dedicated CODEC_ID assigned to it, and it
is considered a subtitle in the
[https://github.com/FFmpeg/FFmpeg/blob/03b88f6b393359957ac9f7f0fb9b148ab51b3da5/libavcodec/codec_desc.c#L2603
codec descriptions]. We do not have a dedicated CODEC_ID for CEA-708 yet,
but we will not distinguish it from subtitles either.
