Description (last modified by michael)

Changing PPS_id between slices of a AU is not allowed in H264, its allowed though to change between fields

This has been reported by Vittorio Giovara to me privately, But he was not able to provide a sample file, so its not easy to fix. Its a "AVCHD 1080i60 file".

Regression since e708424b70bef8641e8a090ec4d9e8c4490db87e
