Fix quantiser matrix parsing in MPEG sequence header #323

Closed brunom closed 6 years ago

brunom commented 6 years ago

The standards says:

load_intra_quantiser_matrix – This is a one-bit flag which is set to '1' if intra_quantiser_matrix follows. If it is set to '0' then there is no change in the values that shall be used.

So the code had it backwards.
