    Hi, D Richard Felker III!

Sometime (on Saturday, December 20 at 15:52) I've received something...

3. Have some common structure type stream_t. Then, for example, video
   stream structure will be:

typedef struct {
  stream_t st;
  ....... /* rest are video-specific */
} video_stream_t;

    Then just assuming from application point of view some *vidstr1 is
stream_t*, from video filter (demuxer, vo, etc.) point of view it's
video_stream_t*. Anyway that video_stream_t may (and must) be created
only by video layer API so there isn't any problem with that. :)

    No problem, I've understood that was a joke. I liked it. :)))

    With best wishes.
