How to Install NDI plugin in OBS flatpak version?

wolfred24 commented 4 years ago

Hi, i want to install NDI plugin for OBS in flatpak version, there is a way to do it?

TingPing commented 4 years ago

I just packaged it up for you, let me know if it works: https://github.com/flathub/com.obsproject.Studio/wiki/NDI-Support

sunix commented 4 years ago

Hey @TingPing I tried, but

there are problems with labels
I couldn't detect other ndi sources in the network (is the avahi bridge working ?), with my obs ubuntu deb package installed on another system, I could even see the NDI sources that I am exposing myself.

TingPing commented 4 years ago

The label issue is surely just a bug in the plugin or obs.

Avahi does indeed not work inside of flatpak, for now at least, so if that is required I'm not sure there is much that can be done.

sunix commented 4 years ago

@TingPing i have seen stuff using avahi in https://github.com/flathub/org.gnome.Rhythmbox3/pull/8/files wouldn't that work ? I don't see what's the point to package NDI if avahi doesn't work ...

sunix commented 4 years ago

@TingPing after having

added that, https://github.com/flathub/com.obsproject.Studio/pull/66
repackaged obs flatpak with the changes
repackaged previous package with obs-ndi flatpak following https://github.com/flathub/com.obsproject.Studio/wiki/NDI-Support

NDI discovery seems to work.

sunix commented 4 years ago

about the labels ... it's not a bug in obs or the plugin, it's just that we don't copy the files in the right folder: https://github.com/Palakis/obs-ndi/tree/master/data/locale

TingPing commented 4 years ago

Pushed the Avahi permission.

about the labels ... it's not a bug in obs or the plugin, it's just that we don't copy the files in the right folder: Palakis/obs-ndi:data/locale@master

Hmm, well I don't have time to look into it further but I'd appreciate anything you figure out.

sunix commented 4 years ago

ok for the labels: https://github.com/flathub/com.obsproject.Studio/pull/68 It works well, but it is not very clean as I couldn't copy the files to another folder through the extension ... I am not expert enough with flatpak :/

TingPing commented 4 years ago

No worries, thanks a lot for looking into it!

The Wiki needs updating as he current NDISDK is v5 and fails to install.

Changes in the .json are.


    {
      "name": "ndi-sdk",
      "buildsystem": "simple",
      "build-commands": [
        "tar -xf Install_NDI_SDK_v5_Linux.tar.gz",

          "type": "file",

        }

However, as I said the install fails, unknown causes.

@develroo maybe worth opening a new issue

pierreavizou commented 2 years ago

A bit out of the blue but I managed to make it work without going through the download on NewTek's website. That's what I did to add NDI support to OBS 27.1.3 ~27.2.0-beta1, should work for stable as well~:

Download https://github.com/Palakis/obs-ndi/releases/download/4.9.1/libndi4_4.5.1-1_amd64.deb from Palakis's repo. It actually contains 4.0 SDK headers files required to build the plugin
Put 'data.tar.xz' from the .deb into the folder you cloned this repo into (likely 'com.obsproject.Studio')
Use the modified manifest below to build the plugin.

I had to build it against the latest stable version (27.1.3) of OBS to make it actually show up in the interface (updated obs source url in the manisfest) ~Note you might want to replace 'beta' with 'stable' if you're on the stable branch~
