firefox - html5 video - default video fallback does not show
firefox, html, video
Solution
Per spec, the browser must not show the fallback if it supports `<video>`, even if it happens to not support the provided codecs..... Hence the behavior you're seeing in Firefox: the spec requires that behavior.
Problem
I use latest firefox browser and I want to show the default `fallback message` when video format does not supported by firefox (as html5 documentation described), but firefox only show `poster` image and text on it "No video with supported format and MIME type found" Any ideas how to show `This is FALLBACK MESSAGE content` (as it must showed) instead of `firefox error message`? thanks ``` <video poster="movie.jpg" controls> <source src="movie.mp4" type='video/mp4; codecs="avc1.4D401E, mp4a.40.2"'/> <p>This is FALLBACK MESSAGE content</p> </video> ```
