This thread started about something which could replace Flash which basically means "in-browser-viewing-capabilities" and therefore HTML5.
From that I guess (I don't know about Firefox internals)
Perhaps I confuse something here but see my other mail where I wrote that for me (Tumbleweed without Flash) YouTube worked but not http://www.spiegel.de/wissenschaft/ I tried a video on the YouTube home page that just worked. As far as I understand what others have posted here this is because YouTube uses HTML5. But in contrast videos on http://www.spiegel.de/wissenschaft/ did not work for me and here Firefox showed a popup that it got an *.mp4 file and asked me what it should do with it (that "Open with" versus "Save File" popup). that this time no HTML5 was used. What I like to tell is that it seems HTML5 alone could be not sufficient to replace Flash. I mean replacing Flash from an user experience point of view, not from a technical point of view.
Firefox (and other modern browsers) are supposed to support HTML5 video. But to do this an external player cannot be used. The player needs to be in the browser. (The codec not necessarily.)
For Firefox that means that it supports out of the box: WebM with VP8 WebM with VP9 Ogg Theora
The H.264 (many times referred to MP4 while that is a very rough match only) which is part of the HTML5 standard is not built in to Firefox because of patent concerns. But Firefox can and will use it if system GStreamer installation provides the decoding capabilities.
Do I understand it correctly that I got that popup in Firefox because Firefox could not find a H.264 codec? If yes, Firefox hides that information from the user which could be crucial at least for some users to proceed. The popup only reads: ------------------------------------------------------------- Opening i248rqwejb_dskfz_16473657_oe85.mp4 You have chosen to open: i248rqwejb_dskfz_16473657_oe85.mp4 which is: MP4 file (12.3 MB) from: http://video3.spiegel.de What should Firefox do with this file? (*) Open with [Browse...] ( ) Save File [ ] Do this automatically for files like this from now on. [Cancel] [OK] ------------------------------------------------------------- If Firefox would have additionally shown its internal knowledge why it shows me that popup (e.g. because it needs a H.264 codec but cannot find one) it would have helped to get an idea what the actual reason is why it does not "just work" in this case. Just for fun: In that popup click on its default selection [Browse...] (or just click [OK]) and follow the further dialogs in good faith to get a solution until you are lost ;-) Addendum 1: Regarding H.264 versus MP4 very rough match: It is Firefox that tells me that it is a "MP4 file". I only used what Firefox had stated what this thingy is. It would have already helped if Firefox had shown it as "H.264 or MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC)" video coding format. Addendum 2: Meanwhile I can play H.264/MPEG-4 AVC videos via /usr/bin/vlc but Firefox still shows that popup which means there is a difference between "no codec for H.264/MPEG-4 AVC installed" and "Firefox cannot find a codec for H.264/MPEG-4 AVC".
