This message contains unregistered user data identified by a UUID

Generic geo-location information. This is error-prone due to the fact that is uses signed integer fields, which are not supported by proto1 API and are cast to unsigned integers. Consider using the metadata_util function directly, which fills out a version 2 API proto.

Note that when a VSI is from a user video, the information reflects the info in that source. Fields like lengths, fps, etc. are not guaranteed to be the same as those of transcodes. If the relevant info in source is too broken, the corresponding fields (e.g., lengths) could be unset or with the default value, meaning VSI cannot compute them from the given info. Next id: 84

Timed text streams refer to the streams that are separated from audio and video streams. Closed caption streams embedded in video streams (e.g. MPEG-2 – Line 21) do not belong here.
