I used QML for a similar application because it would allow me to assemble the OpenGL scene nicely. I used libMPV to render video frames and QML could easily overlay controls and text. You could even render Chromium (QtWebEngine) on the same scene with minimal effort. I know enough to be dangerous, but not enough to dive deep into the stack of technologies, nonetheless, I got a decent app working with no bugs that customers ever ran into. For my skill level and effort put forth, I don't know what I could have used to would have worked as well.
