Function Documentation

av_cpb_properties_alloc()

AVCPBProperties * av_cpb_properties_alloc

(

size_t *

size

)

Allocate a CPB properties structure and initialize its fields to default values.

Parameters

size	if non-NULL, the size of the allocated struct will be written here. This is useful for embedding it in side data.

Returns

the newly allocated struct or NULL on failure

av_xiphlacing()

unsigned int av_xiphlacing	(	unsigned char *	s,
		unsigned int	v
	)

Encode extradata length to a buffer.

Used by xiph codecs.

Parameters

s	buffer to write to; must be at least (v/255+1) bytes long
v	size of extradata in bytes

Returns

number of bytes written to the buffer.
