Comments

Not all file formats support the interleaving mode. For example, AVI file format supports interleaving mode, while WMV file format does not. The interleaving mode is ignored for the formats that do not support it. Interleaving mode tells the multiplexer the method for combining data from various streams (video, audio, etc) in the file. Some interleaving modes will require more processing and more memory, but will generate files more suitable for streaming. Other interleaving modes will be faster, and should be used when speed is necessary (for example, during capture). For more information on these options, refer to ltmmCapture_InterleavingMode Constants.

To change the interleaving mode, call IltmmCapture::put_InterleaveMode.
