A limit on multistream subscription?

to accomodate as more as possible members in a videoroom, we adopt multistream type videoroom but find that the size of sdp increases rapidly with the increase of participants(due to the increase of group bundle section of sdp), which result in failure of some subscription of participants when exceed a certain number(100 or so?), how to fix that, thank you in advance!

Probably related to this, so try this PR
