Yes, that was my point. But, in your definition of "real-time" such buffers are not acceptable. That is why I thought making it clear would be appropriate in the title and text. Both are real-time media but interactive one has a delay budgets which are far less.

I am a bit skeptical about this. The one-way streaming that can tolerate seconds of delay needn't be as reactive to congestion or rate changes as the two-way conferencing apps. Time scales are quite different. Some tools/methods will of course be similar but they will not necessarily be identical or directly applicable.

Some wording in the intro section could help with this.

Thanks.
