All FF_QSCALE_TYPE values used by libavfilter originate from libavfilter (namely from ff_qp_table_extract()); no value is exchanged between libavcodec and libavutil. The values that are exchanged (and used in libavfilter) are of type enum AVVideoEncParamsType. Therefore this patch stops using said FF_QSCALE_TYPE_* in libavfilter and uses enum AVVideoEncParamsType directly. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
