[FFmpeg-devel] [PATCH 0/2] Harmonise comments about ownership/meaning

[Andrew Sayers]

There seems to be a couple of documentation conventions in the code:

  /**
   * - encoding: (who sets this in encoding context)
   * - decoding: (who sets this in decoding context)
   */
  int foo;

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

These are very useful, but the layout causes some issues:

1. (slightly) different layouts are used in some places
2. doxygen renders the "meaning" layout as one big paragraph, which is hard to read
3. the layouts are quite similar, so it can be hard to tell at a glance
   whether a given piece of documentation is talking about ownership or meaning

For a good example of this issue, please see [1].

Harmonise layouts and propose a new layout for meanings:

  /**
   * *Encoding:*
   *
   *   Meaning in encoding context
   *
   * *Decoding:*
   *
   *   Meaning in decoding context
   */

I hope this isn't too forward for my second day around here, but IMHO
this would significantly improve readability.
