BufferList

Buffer lists are an object containing a list of buffers.

Buffer lists are created with Buffer.listNew and filled with data using a Buffer.listInsert.

Buffer lists can be pushed on a srcpad with Pad.pushList. This is interesting when multiple buffers need to be pushed in one go because it can reduce the amount of overhead for pushing each buffer individually.

class BufferList {

protected

GstBufferList* gstBufferList;

protected

bool ownedRef;

GstBufferList* getBufferListStruct(bool transferOwnership);

void* getStruct();

this(GstBufferList* gstBufferList, bool ownedRef);

static GType getType();

this();

this(uint size);

size_t calculateSize();

BufferList copyDeep();

bool foreach_(GstBufferListFunc func, void* userData);

Buffer get(uint idx);

Buffer getWritable(uint idx);

void insert(int idx, Buffer buffer);

uint length();

void remove(uint idx, uint length);

}

Constructors

this this(GstBufferList* gstBufferList, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Creates a new, empty gstreamer.BufferList The caller is responsible for unreffing the returned gstreamer.BufferList
this this(uint size): Creates a new, empty gstreamer.BufferList The caller is responsible for unreffing the returned gstreamer.BufferList The list will have size space preallocated so that memory reallocations can be avoided.

Functions

calculateSize size_t calculateSize(): Calculates the size of the data contained in buffer list by adding the size of all buffers.
copyDeep BufferList copyDeep(): Create a copy of the given buffer list. This will make a newly allocated copy of the buffer that the source buffer list contains.
foreach_ bool foreach_(GstBufferListFunc func, void* userData): Call func with data for each buffer in list.
get Buffer get(uint idx): Get the buffer at idx.
getBufferListStruct GstBufferList* getBufferListStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getWritable Buffer getWritable(uint idx): Gets the buffer at idx, ensuring it is a writable buffer.
insert void insert(int idx, Buffer buffer): Insert buffer at idx in list. Other buffers are moved to make room for this new buffer.
length uint length(): Returns the number of buffers in list.
remove void remove(uint idx, uint length): Remove length buffers starting from idx in list. The following buffers are moved to close the gap.
