- I think we should clarify that this is for video
- missing makes most sense. Because 0 has a semantic meaning , i.e., no losses. In XR blocks, we've used 0xff to represent measurement unavailable, but in dictionaries, skipping the key when not measured seems like good advice.

Special note for jitter as zero has semantic meaning.

TPAC16 decisions:
“” for strings, 0 and -1 for integers are all legal values under some circumstances.
Proposal:
- Unsupported stats are not present in the dictionary
- Stats that haven’t started counting are present with a suitable starting value
- Special considerations when 0 is a suitable value (such as RTT)!
