Why It Matters

This message came from the public MOQ working group archive and captures active discussion, meeting coordination, or implementation feedback around Media over QUIC.

Message Excerpt

I believe the concern with making Subgroup ID a single byte is if you wanted to do Object-per-Subgroup and couldn't or didn't want to use datagrams, you'd be limited to 256 Objects per Group.

Plain-Text Body

I believe the concern with making Subgroup ID a single byte is if you wanted to do Object-per-Subgroup and couldn't or didn't want to use datagrams, you'd be limited to 256 Objects per Group.

Otherwise, making Subgroup ID a byte a very appealing change. Thinking along those lines is what caused me to file #1405 https://github.com/moq-wg/moq-transport/issues/1405 (Single Object Subgroups don't need a Subgroup ID)
