How about ast_codec->frame_bytes?  I believe this belongs to codec not format.  I think data_size is ambiguous.  Without reading the comments or just knowing you would question if the size is bytes or bits, and if the period is a frame, sample, or second.  I like self-documenting code.

Also are we changing the name used for ast_data_add_int?  I don't personally use any of the features from this file so I don't know how important backwards compatibility is.

Changes to those files will be posted separate since I feel they are more complex and likely to have more error's.  If any of the files included in this review fit that description let me know and I will split them off.
