Description

This problem seems to be related to https://github.com/alvr-org/ALVR/issues/1536. Link speeds range from 860 Mbps to 1.2 Gbps on average.

Constant mode is fine. However, like https://github.com/alvr-org/ALVR/issues/1536, the bitrate is not constant at 180Mbps, but equally drops from 0.01 to 5Mbps.

Reproduction is also really simple and 100% bug reproduction success rate. This bug occurs both on Windows and Linux.

Although this setting looks fine, the bitrate gets lower and lower when the headset is not moving, causing the same problem as above.

You don't have filler data enabled, this is user error

@Vixea enable filter data isn't solve this problem. So I set it to the default value.

Look at this screenshot. Filter data enabled and i uploaded video

@Kieaer disable "Decoder latency fixer". This is the cause of the bitrate decreasing over time.

It was solved in disable decoder latency fixer.
