Michael Niedermayer	f90a4bfc43	mlpdec: fix request_channel_layout behavior. When request_channel_layout is 0, all substreams should be decoded. Signed-off-by: Tim Walker <tdskywalker@gmail.com>	11 years ago
Michael Niedermayer	1a8050ad61	avcodec/mlpdec: fix mulichannel output Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Tim Walker	c0c45188e5	mlp: improve request_channel_layout behavior. Don't decode further substreams if request_channel_layout is a subset of the current substream's channel_layout. Before, we would only discard further substreams if request_channel_layout matched the substream's channel_layout extactly, thus decoding additional channels which the caller would probably end up downmixing.	11 years ago
