BufferList

Buffer lists are an object containing a list of buffers.

Buffer lists are created with gst_buffer_list_new() and filled with data using a gst_buffer_list_insert().

Buffer lists can be pushed on a srcpad with gst_pad_push_list(). 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);

BufferList copyDeep();

bool foreac(GstBufferListFunc func, void* userData);

Buffer get(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 #GstBufferList. The caller is responsible for unreffing the returned #GstBufferList.
this this(uint size): Creates a new, empty #GstBufferList. The caller is responsible for unreffing the returned #GstBufferList. The list will have @size space preallocated so that memory reallocations can be avoided.

Functions

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.
foreac bool foreac(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*
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.
