[jitsi-dev] RTCP Termination refactory, now video freezes on packet loss


#1

Since a major refactory of the RTCP Termination strategy took place, I am seeing that videos freeze whenever there’s packet loss.

We didn’t change the strategy, so before when using the default PassthroughRTCPTerminationStrategy any packet loss didn’t really impact a full video freeze.

Now with latest jitsi on master branch, any packet loss results in a video freeze for a bunch of seconds. What is the default strategy right now?

Also when setting to BasicRTCPTerminationStrategy, I am seeing bandwidth constraints are beeing applied to 10000kbit/second. We are using JVB as standalone without jitsi-meet.

Hi Andi,

Thank you very much for sharing your observations with us.

Since a major refactory of the RTCP Termination strategy took place, I
am seeing that videos freeze whenever there's packet loss.

We didn't change the strategy, so before when using the default
PassthroughRTCPTerminationStrategy any packet loss didn't really impact
a full video freeze.
Now with latest jitsi on master branch, any packet loss results in a
video freeze for a bunch of seconds. What is the default strategy right now?

The default now is PassthroughRTCPTerminationStrategy but if you didn't
set it explicitly, NACKs wouldn't work, hence the freezes.

We've just fixed this issue. Thank you for your report!

Also when setting to BasicRTCPTerminationStrategy, I am seeing bandwidth
constraints are beeing applied to 10000kbit/second. We are using JVB as
standalone without jitsi-meet.

What do you mean by bandwidth constraints? 10mbit/sec sounds reasonable
if it's per participant.
