That's not to say that you can't use libav to help you accomplish your requirements, but that libav is really only here for the demuxing, muxing, encoding and decoding of videos themselves. libav does not do (as far as I know) the presentation of the video itself... that's up to some other graphics library (OpenGL, for example). What it sounds like you want is just some sort of canvas type element in your programming language of choice with a map overlay (check out gdal/fwtools for this) and another canvas or something on top of the map canvas that displays video, which is where libav will help you out. Again, your question seems to be more about the overall design and organization of your own application... and as such this is not the correct place to ask about it. Disclaimer: I could be completely wrong; maybe libavfilter can help you in some way. > > _______________________________________________ > libav-user mailing list > [email protected] > https://lists.mplayerhq.hu/mailman/listinfo/libav-user > _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
