Enumeration Type Documentation

enum MovChannelLayoutTag

mov 'chan' tag reading/writing.

Author:

Justin Ruggles Channel Layout Tag This tells which channels are present in the audio stream and the order in which they appear.

Note:

We're using the channel layout tag to indicate channel order when the value is greater than 0x10000. The Apple documentation has some contradictions as to how this is actually supposed to be handled.

Core Audio File Format Spec: "The high 16 bits indicates a specific ordering of the channels." Core Audio Data Types Reference: "These identifiers specify the channels included in a layout but do not specify a particular ordering of those channels."

uint64_t ff_mov_get_channel_layout	(	uint32_t	tag,
		uint32_t	bitmap
	)

mov 'chan' tag reading/writing.

Author:

Justin Ruggles Get the channel layout for the specified channel layout tag.

Parameters:

[in]	tag	channel layout tag
[out]	bitmap	channel bitmap (only used if needed)

Returns:

channel layout
