...ed pretty nicely by the "simple map" that Sampo suggested. This is basically the same thing as the "channel map" described on the wiki, but with the (physical,logical) channel pair swapped. So, using the syntax from the wiki: channel_type = OGG_CHANNEL_MAP_STEREO channel_map [OGG_CHANNEL_FRONT_LEFT] = 1 channel_map [OGG_CHANNEL_FRONT_RIGHT] = 2 This is nice because it makes it impossible for somebody to do something stupid like define two channels as carrying FRONT_LEFT. A player can't handle that situation sanely, but handling both FRONT_LEFT and FRONT_RIGHT mapping to channel 0 is e...

...define the channel map for each supported channel group type. The array syntax I used in my last post probably added to the confusion - look at it again but without using the assigned values to the OGG_CHANNEL_* text. A couple examples: Packet 1: channel_type = OGG_CHANNEL_MAP_5_1 channel_map [0 = OGG_CHANNEL_FRONT_LEFT] = 1 channel_map [1 = OGG_CHANNEL_FRONT_CENTER] = 2 channel_map [2 = OGG_CHANNEL_FRONT_RIGHT] = 3 Packet 2: channel_type = OGG_CHANNEL_MAP_STEREO channel_map [0 = OGG_CHANNEL_FRONT_LEFT] = 1 channel_map [1 = OGG_CHANNEL_FRONT_RIGHT] = 2 Packet 3: channel_type = OGG_CHANNEL_MAP_UHJ channel_map [0...

So, using the syntax from the wiki: > channel_type = OGG_CHANNEL_MAP_STEREO > channel_map [OGG_CHANNEL_FRONT_LEFT] = 1 > channel_map [OGG_CHANNEL_FRONT_RIGHT] = 2 Not sure this is a good idea. Remember that channel_map is just an array (unless you want to make it a map?). So if you had a OGG_CHANNEL_SPECIAL with an id of 1000, it would force 1000 entries in the array. > This is nice because it makes it...
