Allocates a new #GstBaseParseFrame. This function is mainly for bindings, elements written in C should usually allocate the frame on the stack and then use gst_base_parse_frame_init() to initialise it.
a #GstBuffer
the flags
number of bytes in this frame which should be counted as metadata overhead, ie. not used to calculate the average bitrate. Set to -1 to mark the entire frame as metadata. If in doubt, set to 0.
input data to be parsed for frames.
a combination of input and output #GstBaseParseFrameFlags that convey additional context to subclass or allow subclass to tune subsequent #GstBaseParse actions.
media specific offset of input frame Note that a converter may have a different one on the frame's buffer.
output data.
subclass can set this to indicates the metadata overhead for the given frame, which is then used to enable more accurate bitrate computations. If this is -1, it is assumed that this frame should be skipped in bitrate calculation.
Copies a #GstBaseParseFrame.
Frees the provided frame.
Sets a #GstBaseParseFrame to initial state. Currently this means all public fields are zero-ed and a private flag is set to make sure gst_base_parse_frame_free() only frees the contents but not the actual frame. Use this function to initialise a #GstBaseParseFrame allocated on the stack.

Frame (context) data passed to each frame parsing virtual methods. In addition to providing the data to be checked for a valid frame or an already identified frame, it conveys additional metadata or control information from and to the subclass w.r.t. the particular frame in question (rather than global parameters). Some of these may apply to each parsing stage, others only to some a particular one. These parameters are effectively zeroed at start of each frame's processing, i.e. parsing virtual method invocation sequence.
