however since they are not essential for decoding, just ignore the whole
block and try to finish parsing the VUI.

9ecabd7892 h264: reset num_reorder_frames if it is invalid 
An invalid VUI is not considered a fatal error, so the SPS containing it
may still be used. Leaving an invalid value of num_reorder_frames there
can result in writing over the bounds of H264Context.delayed_pic.

  h264_ps: when parsing a VUI fails, only abort when explode is set

Merge only for metadata, ignoring invalid data can put the context
into an invalid state and can possibly be used for remote code
execution exploits.
Also we support all non standard VUIs that have been reported so
ignoring parsing failure makes no sense for us unless theres
some issue that has not been reported
