ffmpeg is installed

== From twitter web page: error in web console:

For example, on twitter i get a "the media could not be played" placeholder and this in the web console:

HTTP “Content-Type” of “video/mp4” is not supported. Load of media resource https://video.twimg.com/amplify_video/1149302678771683333/vid/1280x720/qFCcMLAnjR_MBans.mp4?tag=13 failed. home

The video on this page can’t be played. Your system may not have the required video codecs for: video/mp4; codecs="avc1.42E01E mp4a.40.2"

When i click on that link in the error it saves the video to /tmp and plays it in ffplay.. and in preferences->Applications, video/mp4 shows up with ffplay configured.

== Plays fine with a local file

When I put that mp4 link in the address bar, it gives me a download dialog, I can download that file, and play it in firefox from the command line:

firefox qFCcMLAnjR_MBans.mp4

== Plays fine with a local html file with the video control html element:

When i open a local html file with the video control element that plays the video. So why do I get those errors when this is viewed on the twitter website?

Any pointers appreciated.

Thanks!

Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.
