Did some further investigation. I’ve build fbpdf (https://github.com/aligrudi/fbpdf, with all the -lmupdf-* removed from the Makefile to make it build) and this works very well. With pipe-viewer I can watch YT video’s (which uses mpv under the hood).

Thanks for the inspiration.

Thanks for the reply.

Really Nice.

Could you elaborate on what programs you use tot display PDF files and which browser you use?
