PTMemoryFilter

@interface PTMemoryFilter : PTFilter

MemoryFilter is a memory buffer that can be used as a source or a sink Filter in the Filter pipeline. When a MemoryFilter is the source, other filters can read data stored in memory; When MemoryFilter is a sink, other filters generate data which is then pushed in a memory buffer owned by MemoryFilter (MemoryFilter makes sure that there is enough space to accommodate all data).

  • Note

    MemoryFilter specific function.

    Declaration

    Objective-C

    - (NSData *)GetBuffer;

    Swift

    func getBuffer() -> Data!

    Return Value

    a pointer to the beginning of the buffer. Use method Count() to determine the number of bytes written to or read from MemoryFilter.

  • Note

    MemoryFilter specific function used to change filter mode from output to input. The utility function is useful in cases when and output data buffer should be converted to an input stream.

    Note

    The function has no effect on an input MemoryFilter.

    Declaration

    Objective-C

    - (void)SetAsInputFilter;

    Swift

    func setAsInputFilter()

  • Undocumented

    Declaration

    Objective-C

    - (instancetype)initWithBuf_sz: (unsigned long)buf_sz is_input:  (BOOL)is_input;

    Swift

    init!(buf_sz: UInt, is_input: Bool)
