OBS drops all frames

[TicTac9k1]

Done the following;

Reinstalled OBS Restarted modem/router

Made sure the settings of OBS are the same as the requirement page from Mixer https://watchbeam.zendesk.com/hc/en-us/articles/115000638643-Streaming-With-OBS-FTL

When I revert to version 18.0.1 FTL everything works fine.

I can second this issue.

For me, I can load the alpha build up, it works fine on the first scene or for the first few minutes but the second I either switch scenes or a movement happens on the beginning scene I start dropping frames.

What I have done for troubleshooting: Duplicated issue on both wired and wireless. Restarted modem/router Called ISP and I have been told I am green across the board. I have changed bitrates around between 1800 - 3500 for 720p 60fps and 720p 30fps. Have tried on both CPU x264 and NVENC.

When I revert to the previous version 18.0.1 with FTL, I am not seeing these issues. I have attached the latest log for the alpha build. 2017-08-04 15-14-17.txt

I have seen this issue and the high CPU issues before. Long before Alpha OBS-Studio. I believe the problem is OBS-Studio and OBS-FTL share the same settings / profile / scenes file locations. But not necessarily are they compatible with both programs / versions. Switching back and forth between OBS-FTL and OBS-Studio can overwrite the settings files and may be causing corruption.

Try this to test this theory.

1. Make a backup of %appdata%\obs-studio folder including all sub folders (this is your current scenes and settings)
2. Delete the %appdata%\obs-studio folder
3. Run OBS-Studio (Alpha version) and set up all your settings from scratch.
4. Create a scene so you can test and see if you still have the same issues.

Be sure that at no time while your testing you run OBS-FTL. If the drop frames stop then you will know how to fix it. Just setup everything from scratch and never run OBS-FTL again.

Yes, I thought it might have been the same issue as you described but when I did my testing I always uninstall older OBS versions just to be on the safe side.

So just to be on the safe side I went step by step through what you said. Uninstalled and removed the %appdata%\obs-folder just in case this time still having the same issues. I also search through just to be sure no remains of previous builds were around. Installed only the OBS-Studio (Alpha Build) and completely re-setup all setting by scratch. Still causing the same results I started with a static scene of an image and then moved to a game scene and immediately moving to the game scene I would drop frames.

I did a complete uninstall of OBS Alpha build, manually removed the %appdata%\obs-studio folder and installed the previous OBS-FTL version 18 and it works 100%.

Are you still seeing this with the latest release version of OBS?

[georgeFluff]

Just saw this, I have this issue and I drop >100% of the frames

[Vaygrim]

I'm suddenly getting this exact same issue. Latest build of OBS Studio for Windows, as of DEC-22-2017.

[Maximilian-Reuter]

If I remember correctly there was a change, that included lost packets in the dropped frame statistic

[narcogen]

Should probably report it to the OBS devs, then, and not here.

[Maximilian-Reuter]

well thing is it kinda happened here https://github.com/mixer/obs-studio-ftl/blob/c7f8471eadb1af04ff89c0de23e24d363b5a3d80/plugins/obs-outputs/ftl-stream.c#L957 so...

[QuinnDamerell-MS]

Yup. We implemented the API wrong and increment the dropped frame count when we lose a single packet. Since frames typically get broken into 6-8 packets, you can get in the hundreds. Also, lost packets aren't the end of the world - we can recover some of them. We will fix this soon. :)
