API changes, most recent first:
2011-05-10 - xxxxxxx - lavc 53.3.0 - avcodec.h
Deprecate AVLPCType and the following fields in
AVCodecContext: lpc_coeff_precision, prediction_order_method,
min_partition_order, max_partition_order, lpc_type, lpc_passes.
Corresponding FLAC encoder options should be used instead.
2011-04-XX - bebe72f - lavu 51.1.0 - avutil.h
Add AVPictureType enum and av_get_picture_type_char(), deprecate
FF_*_TYPE defines and av_get_pict_type_char() defined in
