ld-discmap should correct CAV/CLV disc type flags #469

Open simoninns opened 4 years ago

It's possible, due to VBI corruption, for some frames to be marked with the wrong disc type. ld-discmap should correct the disc type of all frames to match the detected disc type.

This is more correctly described as general VBI correction as the disc type is determined by counting the number of valid CAV picture numbers or CLV timecodes at the start of the metadata. So an 'incorrect' flag is really a corrupt set of VBI data.
