[FFmpeg-devel] [PATCH 2/2] all: harmonise "{Decoding, Encoding, Audio, Video}:" comments

[Andrew Sayers <ffmpeg-devel@pileofstuff.org>]

There seems to be a convention for documenting meanings:

    /**
     * Encoding: (meaning in encoding context)
     * Decoding: (meaning in decoding context)
     */

At a glance, these are confusingly similar to ownership comments.
They are also rendered by doxygen as long, hard-to-read paragraphs.

Reformat these comments to be more visually distinct and readable.
