Constructors

class BaseParseFrame

classmethod new(buffer: Buffer, flags: BaseParseFrameFlags, overhead: int) → BaseParseFrame

Allocates a new BaseParseFrame. This function is mainly for bindings, elements written in C should usually allocate the frame on the stack and then use init() to initialise it.

Parameters:

• buffer – a Buffer

• flags – the flags

• overhead – 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.

Methods

class BaseParseFrame

free() → None

Frees the provided frame.

init() → None

Sets a BaseParseFrame to initial state. Currently this means all public fields are zero-ed and a private flag is set to make sure free() only frees the contents but not the actual frame. Use this function to initialise a BaseParseFrame allocated on the stack.

Fields

class BaseParseFrame

buffer

Input data to be parsed for frames.

flags

A combination of input and output BaseParseFrameFlags that convey additional context to subclass or allow subclass to tune subsequent BaseParse actions.

offset

Media specific offset of input frame Note that a converter may have a different one on the frame’s buffer.

out_buffer

Output data.

overhead

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.
