demux_FilterChainNew()

demux_t * demux_FilterChainNew	(	demux_t *	source,
		const char *	list
	)

Builds an explicit chain of demux filters.

This function creates a chain of filters according to a supplied list.

See also stream_FilterChainNew(). Those two functions have identical semantics and ownership rules, except for the use of demux vs stream.

Parameters

source	input stream around which to build a filter chain
list	colon-separated list of stream filters (upstream first)

Note

Like stream_FilterAutoNew(), this function takes ownership of the source input stream, and transfers it to the first demux filter in the constructed chain. Any use of the source after the function call is invalid and undefined (unless the chain ends up empty).

Returns

The last demux (filter) in the chain. The return value is always a valid (non-NULL) demux pointer.
