You could use some patterns.

1. Use screen recording software. e.g. Xbox Game Bar

2. Save the render target as PNG in sequence. You use glReadPixels after glSwapBuffers to save the render target as a PNG. A sequencial PNG files can be converted to video using ffmepg.

3. Save the render target to memory and encode movie. You use glReadPixels after glSwapBuffers to save the render target to memory. Images can be converted to video using the library.

e.g. ffmepg, MediaFundation
