I installed OBS Studio via Discover, but, when I open it, it gives the following error dialogue, and then quits:
Failed to initialize video. Your GPU may not be supported, or your graphics drivers may need to be updated.
Is there any solution to this problem? I am using a Dell Inspiron 6400 laptop with Lubuntu 20.04.1 LTS (dual boot with an old version of Windows). In case it were relevant in diagnosing the problem, here are some of my CPU details (extracted via lshw):

I have read a few fora online, most of them concerning Windows operating systems. Some suggest the situation can be resolved by installing a third-party plug-in; others say that it is an inherent limitation of the hardware, and that no solution is possible (short of changing the graphics card inside the machine or getting a new computer).
If it would not be possible (or would be very difficult) to make OBS Studio work, I would be interested to hear about any alternatives that would work (NB: I already have Audacity, but that does not do video). I know my laptop is old, but it does manage to run Audacity, Zoom, and Skype without problems (as long as I do not try to run them simultaneously!), so I am hopeful that there would be some means of editing video and even broadcasting it in real time. I know VLC can receive live broadcasts, but am not clear as to whether it has a webcam+mic live broadcasting mechanism.
