2010-07-22 - r24424 - lavfi 1.26.0 - media format generalization
325
  Add a type field to AVFilterLink.
326
327

329
  enum PixelFormat *formats -> int *formats in AVFilterFormats
330
  enum PixelFormat *format  -> int format   in AVFilterLink
331
332
  Change the function signatures:
333
  AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
334
  AVFilterFormats *avfilter_make_format_list(const int *fmts);
335
336
