Some options and information for those not seeing video show up in OBS Studio
Please be aware that OBS v24 to v26.0 does not natively support VDO.Ninja, but version 26.1.2 and newer does.
StreamLabs OBS for macOS also does not support VDO.Ninja as of yet, but it should in the future after it updates.
Use the Electron Capture app if you are using a non-compatible version of OBS. > Get it here <
Ensure that the “Enable Browser Source Hardware Acceleration” checkbox is checked in the advanced settings. If you still get just black video when it’s checked, then you can try:
Updating your graphics card drivers
Go to the windows setting for “Graphics Settings”. You may see OBS or SLOBS under programs listed for “graphics performance preference”. Make sure OBS or SLOBS is set to “high performance”. Turn on hardware accelerated GPU scheduling.
Run OBS as an Administrator
Update OBS Studio to the newest version. When doing so, fully uninstall the old version before installing the new version. If you are up to date, try the beta release or just re-install.
If using OBS 64-bit, try installing the 32-bit version instead of OBS.
Switch the GPU used by OBS if using an NVidia GPU; settings in the Nvidia control center.
Enable Compatibility Mode for OBS; this setting is available via right-clicking the OBS icon and clicking properties.
Try a different video codec; perhaps &codec=h264 or &codec=vp9, which can be added to the view links
In the OBS Settings -> Advanced menu, disable Browser source hardware acceleration, and then restart. If it works then, the above GPU-related options should work. Otherwise, it might be a firewall, VPN, or privacy software.
Check to make sure you are not behind a corporate firewall or on a VPN (see Network issues below)
Disable any Anti-virus or other security software
Uncheck the Hardware Acceleration checkbox -- does it work now? If so, it may be choppy, but perhaps still usable
