int(* H264DSPContext::startcode_find_candidate)(const uint8_t *buf, int size)

Search buf from the start for up to size bytes.

Return the index of a zero byte, or >= size if not found. Ideally, use lookahead to filter out any zero bytes that are known to not be followed by one or more further zero bytes and a one byte. Better still, filter out any bytes that form the trailing_zero_8bits syntax element too.
