This patch adds a new static function get_qt_codec() that takes care of the initial retrieval of the fourcc and codec ID for A_QUICKTIME and V_QUICKTIME. It also normalizes noncompliant private data found in some older files that incorrectly starts with the fourcc by expanding/shifting the data by 4 bytes, and storing the data size at the start. This is necessary in order for the rest of the code in the A_QUICKTIME and V_QUICKTIME blocks (and most likely other code as well) to correctly parse the private data. Signed-off-by:
