I have this problem as well... StreamFX had this same issue which they fixed by adding an hook to to obs_frontend_add_event_callback to delay the instantiation of the QWidget until the OBS UI was fully started. My C++ is really rusty and I know nothing about QT, so this would take me a bunch of time to figure out that I just don't have at the moment, but it seems to me that the obs-ndi check that the OBS window is defined is not sufficient. Where they do that simple check, they need to register a callback handler for the frontend to be completely defined before they try to create the output settings widget.

If anyone here more QT hip.. here is the link to the StreamFX pull request where they fix the same error in QT.

jasalt commented 1 year ago

Tried to work around this by building 28.1.2 and got it loading up with minor plugins path fixing but it seems to work only partially.

Testing sending/receiving video with a working Windows 10 (OBS 29.0.2, obs-ndi 4.11.0, ndi sdk 5.1.1.0) and NDI HX Camera and NDI Monitor apps on iOS, these are working ok sending feed front and back.

Works:

NDI feed network discovery as a receiver and as a sender
Receiving NDI feed from Windows OBS
Sending NDI output from OBS to itself (video feedback) or from OBS to another OBS instance on the same computer

Kinda works:

Sending output to NDI Studio Monitor on Windows computer (initially black screen and shows up after few minutes, not sure of audio)

Not working:

Sending output to OBS on Windows computer or to iOS NDI Monitor (black screen)
Receiving feed from iOS NDI HX Camera app (decoder not found screen)

Tried to fix the "NDI® Video decoder not found. Please visit ndi.tv/formats for help and information." screen from HX Camera app as a source looking at earlier issue #842. Tried to install libavcodec-extra58 package's bookworm equivalent libavcodec-extra59 but didn't help. Looked at file differences between 58 and 59 packages and symlinked new paths to old but that didn't help.

Plugin menu texts were also bit off but I guess just cause of incorrect localization file paths.

Hope this could give some clues. Might be partially related to OBS 29 compatibility also.

Build OBS 28

git clone --recursive --branch 28.1.2 https://github.com/obsproject/obs-studio.git
cd obs-studio

cmake --build build --target package
sudo dpkg -i build/obs-studio-28.1.2-1-Linux.deb

Install obs-ndi and libndi

# Noted that after building OBS, the plugin install path /usr/lib/x86_64-linux-gnu/obs-plugins/ was wrong. Fixed with:

OBS 29.0.2.1-1+b1 via Debian. same error about Must construct a QApplication before a QWidget.

I had been using flatpak OBS but didn't see a way to plugin install for flatpak'd OBS and you provided a .deb for Debian :)

If anyone here more QT hip.. here is the link to the StreamFX pull request where they fix the same error in QT.

Xaymar/obs-StreamFX#428

it looks like it's mostly a re-ordering of code. even the Qt error makes it sound like a simple "order of operations" issue. maybe the fix is quite simple ...?

johnthq commented 11 months ago

looks like i seem to be having this issue as well. OBS 29.0.2.1+b1 on debian 12.1 with plasma. Second i install OBS-NDI cant get it to start.

paulpv commented 9 months ago

I've seen this before myself, but thought it was fixed in recent releases.

Regardless, I will soon release a 4.12.0 version w/ updated NDI lib that might help/avoid this crash.

You can try out 4.12.0 Release Candidate if you want.

The Pull Request https://github.com/obs-ndi/obs-ndi/pull/919 has been labeled with "Seeking Testers" and the build generates installer packages that you can download try out.

Steps:

Browse to https://github.com/obs-ndi/obs-ndi/pull/919
Click on "Show all checks"
Click on any of the "Details"
Click on "Summary"
Scroll down and see the "Artifacts"
Download the relevant Linux/MacOS/Windows artifact for your platform
Windows may complain that the download looks suspicious; you may safely ignore
Unzip the download
Run the installer

I think this error is new / different at least. it could have to do with NDI versions on my machine (Jul 26 2023 5.6.0') or differences between Debian and Ubuntu or even differences with OBS versions.

the only hits for that string are Issues, not code => https://github.com/search?q=%22which+is+more+than+libobs+currently+supports%22&type=issues

at least one result implies it could be OBS version at build vs runtime.

profdecoy commented 9 months ago

I still get the OBS core dump with version 29.1.3.1-2 on Ubuntu 23.10 with the latest test build of obs-ndi 0.4.12 . During the pre-release development builds of 23.10, I was able to still run the OBS Project's build of OBS from their Ubuntu PPA with the prior 0.4.11 release of obs-ndi. However, they haven't performed a build for 23.10 yet and the 23.04 version can no longer be installed due to dependency conflicts.

The problem has got to be with that:

Looks like you are running OBS 29.0.2.1-1+b1 (linux) and Qt5. Can you try OBS 29.1.3?

@dancemore @paulpv got further with the Flatpak installation, plugin loads but it trips loading the /usr/local/lib/libndi.so.5.

Information about OBS Flatpak plugin installation path and folder structure was bit under a rock. This obs-multi-rtmp tutorial helped https://youtu.be/p4eoEoq438M, it is linked at https://github.com/sorayuki/obs-multi-rtmp/issues/281. Not sure if this persists between flatpak updates, guessing it would.

The flatpak expects folder structure under ~/.var/app/com.obsproject.Studio/config/obs-studio/plugins/obs-ndi:

It should try loading /usr/local/lib/libndi.so.5 which is there, debian obs version did find and load it earlier. Does it trip because of Flatpak sandboxing related issue as it's owned by root? Should/could there be an additional loading path maybe under ~/.var/app/com.obsproject.Studio/config/obs-studio/plugins/obs-ndi/data/?

ls /usr/local/lib/
libndi.so  libndi.so.5  libndi.so.5.6.0

Not sure how running flatpak as root would effect, tested it too but it gave same error loading libndi after:

sudo -i
cp -r /home/user/.var/app/com.obsproject.Studio/config/obs-studio/plugins /root/.var/app/com.obsproject.Studio/config/obs-studio/
flatpak run com.obsproject.Studio

OBS 29.1.3 is compiled and running under Qt5. obs-ndi is compiled and running under Qt6.

From OBS Discord support:

Qt6 is recommended and the default for 28 and later (it can fallback to Qt5 while building). For 30 Qt6 becomes required. ... until 30.0 gets released and the ppa updates, they should be able to grab the mantic beta package and run that ... Or a little better use the unstable PPA for OBS beta/rc.

I say try installing the official OBS .deb build from: https://github.com/obsproject/obs-studio/releases/tag/29.1.3 OBS says those compile w/ Qt6 and that Ubuntu's versions of OBS Ubuntu compiles themself with Qt5.

I will see what I can do to build a Qt5 supported version, but no promises, and OBS v30 is due out soon anyway.

paulpv commented 9 months ago

@jasalt I remember fighting flatpak loading problems before. If I recall correctly, yes, flatpack (or something similar) has no permission to read outside of its .var folder, so it cannot load anything from /usr/local/lib/. I thought I once was near a solution for this, but I probably just gave up after spending a few days fighting it.

jasalt commented 9 months ago

@paulpv Ubuntu Lunar .deb installed on Debian 12 and obs-ndi runs now. Tested capturing NDI output from OBS locally on NDI input of another OBS instance. Testing more later...

# Cleanup previous installs
sudo apt remove obs-studio libobs0
flatpak uninstall com.obsproject.Studio

# Obs lunar deb install
wget https://github.com/obsproject/obs-studio/releases/download/29.1.3/obs-studio_29.1.3-0obsproject1.lunar_amd64.deb
sudo apt install ./obs-studio_29.1.3-0obsproject1.lunar_amd64.deb

# Obs-ndi plugin from https://github.com/obs-ndi/obs-ndi/pull/919
sudo apt install ./obs-ndi-4.12.0-ubuntu-22.04-x86_64-852999ce7/obs-ndi-4.12.0-x86_64-linux-gnu.deb

Quite happy if it ends up working like this, eventhough it's bit scary to install Ubuntu branded .deb as it could break installation if they decided to add some non-debian dependency AFAIK.

Wondering, would it simply work for Flatpak too if NDI library files were just copied over to folder Flatpak had access to? Would it be hard to add such extra library search path to obs-ndi plugin code?

paulpv commented 9 months ago

All of this package management stuff is a bit over my head. If anyone can make sense of it and articulate a solution I'll give it a try, but this seems lower priority now.

profdecoy commented 9 months ago

The OBS project just published their release of OBS 30.0.0 to their Ubuntu PPA a few minutes ago, including a release for Ubuntu 23.10. With OBS 30 and the latest pre-release build of obs-ndi, it no longer crashes at startup for me. Will test that it works for Video output and receiving.

Works for me too. I installed the Ubuntu Lunar .deb on my Debian box with minimal issues; I had to remove Debianobs-studio, obs-plugins, and libobs0 first.

I have successfully run "mixed" Debian systems for years. Upstream and Official IRC Channels don't like to talk about "apt pinning" very much, but that's the keyword you need to research if you want to learn the advanced tricks or safety nets available when running a "mixed" system. For example, I generally "pin" to Stable but can pull in packages from Testing if I manually force it.

@paulpv said:

I conceptually understand it; but Packaging in general is often "a complete mess" and I do not fault you for skipping it.

I'm generally a cranky old UNIX person and prefer system packages like .deb or .rpm; but for reasonably complex projects like Desktop software, flatpak has been really really effective for me as an Enduser, so that's where I'm casting my vote (however flatpak OBS is incomplete too right now, it's missing VLC as a source 🤦 )

that said; I couldn't make sense of how flatpak packaging worked. I think I read and attempted everything @jasalt did related to flatpak, with no success.

I have used this tool over the years to assist building .deb and .rpm packages, but I've been too busy in the Docker ecosystem to need to build my own system packages lately ...

libndi is not the problem; libndi does and did work fine with obs 29. The problem is that obs-ndi is intended for obs 30 and obs 30 requires Qt6.

If you want the latest obs-ndi to run on obs 29 then you would have to compile a special version to that uses Qt5.

My understanding is a clear as mud maybe: https://docs.ndi.video/docs/sdk/software-distribution#redistributables-ndi_sdk_dir-redist-.exe

You can redist the latest runtime in your installer or provide a link to their latest installer. I prefer to play it safe and stay away from redisting and just let them install it on their own. We have a pop-up in the app with a link to the redist url if the runtime is not detected, but the url comes from the library, and we are using ndi 5 so it wouldn't point to latest into I update it... "soon".

Thanks for the build, OBS doesnt crash on start anymore, but now it segfaults when I try to add an NDI source, anything I could try/provide to resolve this issue?

paulpv commented 4 months ago

Not at all. libndi works fine on either obs-ndi < 4.13.x on obs < 30, or obs-ndi >= 4.13.x on obs >= 30. there is no direct conflict with libndi with either obs-ndi or obs or even Qt5 or Qt6.

The only conflict is obs 30 requiring Qt6. obs-ndi 4.13.x targets only obs 30, so obs-ndi 4.13.x requires systems that support Qt6.

None of this has anything to do with libndi being [in]compatibility with anything listed above...because libndi itself is not directly incompatible with any of this.

aah my bad, i was confusing libndi with obs-ndi.. so what I mean in my first comment was basically which version of obs-ndi I would need for obs 29.
