If 21.3 can be handled -> get big_264.mp4 else if 20.9 can be handled -> get medium.mp4 else get small.png additionally get small2.png or to put it another way.... > What if I can't do 21.3, but can do 20.9, do I show the 21.3. > fallback or not? You show it. that's how you have defined it. If you can't do 21.3, you get everything within the video tag. It is then a seperate case > <video src="medium.mp4" type="video/mp4; codecs=mp4v.20.9"> > <img src="small.png" alt="alternate image for non-video > browsers" /> > </video> If you can do that you will get the video + the remainder of the fallback from 21.3 If you can't do that, you will get the fallback from 21.3 AND the fallback from here. That would be my understanding. > > What would happen if I did this? > > <video src="big_264.mp4" type="video/mp4; codecs=mp4v.21.3"> > <video src="medium.mp4" type="video/mp4; codecs=mp4v.20.9"> > <img src="small.png" alt="alternate image for non-video > browsers" /> > </video> > <img src="small2.png" alt="More alternate text" /> > </video> > > Which fallback is the correct if I can't use either mp4v.21.3 or > mp4v.20.9?
