Methodendetails

onPadChainListFunction

int onPadChainListFunction(CallbackHandler __self,
 @Nonnull
 Pad pad,
 @Nullable
 Object parent,
 @Nonnull
 BufferList list)

A function that will be called on sinkpads when chaining buffer lists.
The function typically processes the data contained in the buffer list and
either consumes the data or passes it on to the internally linked pad(s).

The implementer of this function receives a refcount to @list and
should gst_buffer_list_unref() when the list is no longer needed.

When a chainlist function detects an error in the data stream, it must
post an error on the bus and return an appropriate #GstFlowReturn value.

Parameter:

pad - the sink #GstPad that performed the chain.

parent - the parent of @pad. If the #GST_PAD_FLAG_NEED_PARENT flag is set, @parent is guaranteed to be not-%NULL and remain valid during the execution of this function.

list - the #GstBufferList that is chained, not %NULL.
