GST_BYTE_READER_INIT()

#define GST_BYTE_READER_INIT(data, size) {data, size, 0}

Scan for pattern pattern with applied mask mask in the byte reader data, starting from offset offset relative to the current position.

The bytes in pattern and mask are interpreted left-to-right, regardless of endianness. All four bytes of the pattern must be present in the byte reader data for it to match, even if the first or last bytes are masked out.

It is an error to call this function without making sure that there is enough data (offset+size bytes) in the byte reader.
