Bug Report OBS 16.2 Never stops dropping frames (once triggered)

[lostbacon]

When dropping frames is triggered, it never stops dropping frames. It will continue to send AUDIO ONLY even when bandwidth clears up.

I tested the server against FMLE (which also detects and drops frames) without any problems. The conditions are entirely artificial for engineering purposes.

Bump, the code that triggers the drop frame to occur never resumes normal operation when bandwidth becomes available.

Hi! Please post a log.

Hi! Please post a log.

The log doesn't give anything useful. Just provides the number of dropped packets.

The % dropped frames is proportional to how long the stream has been running. If its been running for two days and dropping frames for 5 minutes the overall % is low.

For testing purposes check your router and see if it has ipv6 enabled. Disable it and see if its still dropping frames. I've run into an issue like this myself and ipv6 on the router was causing the issue. Apparently it wasn't impemented properly on the router.

This is local to local; the RTMP ingest server is on the same network; there is no router. I can artificially restrict flow (or run a program that eats 100% cpu on the server) to force the drop frames to occur however when bandwidth becomes unlimited again the packet drop does not cease. At that point, only audio frames are transmitted.

This is very easy to test, install NetLimiter 4; run OBS; set UL to some value less than what OBS needs... wait for dropped packets... disable UL and watch it drop packets for forever.

I tried your steps, but the moment i disable the limit in Netlimiter it stops dropping frames.

I'm testing this on Windows 10
Both 32 and 64 bit versions have the same behavior.

This is a new bug; older versions did not have it.

Are you using the public 16.2 build?

 

[Osiris]

Yes I am using 0.16.2.

I'm going to continue to investigate this for the rest of the day. I already found that OBS isn't sending the WinAck message when it connects to the server. I'm not sure if OBS relies on the Ack message to determine throughput or not.

What are you using for screen recording on Windows?

 

[Osiris]

I use ShareX for fast screen region recording.

 

[lostbacon]

I tried it against FMS and the same thing occurs. It is also more likely to occur while Screen Recording is enabled.

Flash Media Live Encoder works perfectly dropping and resuming.

I uninstalled obs, selecting the "remove configuration settings" then reinstalled. It it now working properly. For the life of me, I don't know what setting there was that would interfere with this but it seems to work now.
