Bug Report Video capture from webcam lagging with OBS 19.0.3

I updated to the most recent version of OBS (19.0.3) and a new problem appeared - Video started lagging both for recording and streaming. Nothing like this ever happened with the previous version.

No new scenes, nothing additional, I am recording with exactly the same settings as the previous version. Now Lag.

Is anyone else having the same issues? Any known solution?

Log file attached.

Thanks,
Slavi

Each new major version since 17 seems to be less performant on OSX. Not sure why.

I now keep multiple versions installed and just use the oldest one that has the features I need.

For instance, copy/pasting of sources and filters from one scene to another is only in 19, so I open that to modify scenes, then switch to 17.0.2 to actually stream.

How do you switch easily from version to version? Can you please give me a link to the best recording and streaming version of OBS?

After you install a version of OBS, rename the app to include it's version number. You can then run another installer that will put the application "OBS.app" in your Applications folder. Rename that one according to its version number... etc, etc. The different versions use the same preferences and scenes

These are versions I use:

https://github.com/jp9000/obs-studio/releases/download/19.0.3/obs-mac-19.0.3-installer.pkg
https://github.com/jp9000/obs-studio/releases/download/18.0.1/obs-mac-18.0.1-installer.pkg
https://github.com/jp9000/obs-studio/releases/download/0.16.2/obs-0.16.2-installer.dmg

Those are the most recent, official versions of OBS available with installers for MacOS. For whatever reason there was no official MacOS release of version 17, but there is a special version of 17 for use with Mixer that also supports all the regular RTMP services and local recording of the official branch.

For low latency streaming to Mixer (used to be Beam) there are 'official' forks of OBS that support this. The fork is called OBS-FTL. It generally has all the same features of the equivalent OBS version number, with added support for FTL streaming to Mixer. The project does NOT recommend simultaneous streaming with FTL and local recording, but to be honest I have never had a problem with it. YMMV.

https://github.com/mixer/obs-studio-ftl/releases/download/ftl.30/OBS_Studio-FTL.17.0.2.ftl.30.dmg

Those are the newest available official binary releases from OBS and OBS-FTL.

I have compiled my own binaries of newer versions, however these reportedly cause problems for people with versions of certain libraries (namely Qt5) in different places from my system, so these may not work for everyone:

18.0.1 with FTL 0.9.4
https://dl.orangedox.com/1NOky8MIML4AK89PLu

OBS-FTL 17.0.2 with FTL .32
https://dl.orangedox.com/vc0i8NLpKL0Vbwr6ye


There is not yet an official Mixer release of OBS-FTL that comes from the 19.x branch of OBS; however, another programmer has made such a build:

https://github.com/dorianmuthig/obs-studio-ftl/releases

He does not have a MacOS binary, so I compiled one:

OBS-FTL 19.0.2 with FTL .94

Thanks for the answer Narcogen!

You helped a lot!

I hope that the OBS Team soon fixes all the problems with the Mac version.

I still have troubles running my 60 fps camera. Only using 30 fps...

obs-studio-x64-ftl.32-1-g27b64a5-modified.dmg -- preferences panel is too tall to fit on a 720p display. You cannot see or click the "save" button.

And now that I got it to run, the same "too tall" is seen in 18.0.0-0.9.4-modified

You'd be better off filing those as bug reports on GitHub against those projects-- all I did was compile the source that was there, I don't have any way of fixing these problems.

Yea, it was filed against OBS 18 3 months ago, for Linux, and I bumped the bug report and indicated Mac as well.

Microsoft Windows systems apparently can resize that window.

Hmm ... CoreImage *is* there in 10.9.5, inside of Quartz. Lets see what a symlink will do ...

EDIT: Crashing on Qt5's newest version, that's what it will do.
Never gets anywhere near a CoreImage call.

I've seen complaints from various locations about crashes relating to having versions of Qt newer than 5.7.
