Hey, I'm a bit concerned with the outputs this generates for low channel count streams. al17_44.mp4 has two front SCEs. "ISO/IEC 13818-7:2005(E), 8.5.3.2 Explicit channel mapping using a program_config_element" says: Included in the PCE are “list of front channels”, using the rule center outwards, left before right. In this list, a center channel SCE, if any, must come first, and any other SCE’s must appear in pairs, constituting an LR pair. If only two SCE’s are specified, this signifies one LR stereophonic pair. Before the patch we were getting L+R. With the patch we are getting (FC+TFC) (0x2004). I know of at least one commercial encoder that supports unpaired dual mono. Do you know which spec the contains the eratta for top channels? There doesn't seem to be much of value in Amd.6. Do you have any real examples of a multichannel stream with a top center speaker or any supporting documentation you could point me at?
