 Changing PPS_id between slices of a AU is not allowed in H264 so these
 samples are strictly speaking invalid but it would be nice to support them
 anyway.

 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
