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!

Hi,

it is possible to be active and see the HD by following the following link

https://support.mozilla.org/en-US/kb/firefox-4k-ultra-high-definition-youtube-videos

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


gvfs-mime --query video/mp4
