Anomalie #4198 : Le W3C ne valide pas les atttribut width et height qui ne sont pas des entiers.

Mozilla Firefox 36 has problems playing my h264 MP4 files
11 juin 2015, par Wolfgang PürstnerI try to convert videos with ffmpeg to mp4 format (h264) Profile : High Level : 3.1 (1280x720 with 30fps), Bitrate 1500k
The video plays very well in every browser except in Firefox.
http://5.79.72.89/trailer/trailer.mp4
At first it needs longer to load and when I seek inside the video most times the video don’t stop to load and never plays again.
I can see a lot of partial downloads in the developer console. A lot of them are for the initial play and the rest of the requests are during the video load when I seek to a later position.
When I play other h264 Videos (MP4 with similar settings) they play without problems on this server.
And when I put my video on another webserver (apache) there are the same problems with Firefox.For this reason I believe it has to do something with me my conversion.
My settings :
Debian 7 (wheezy)
Webserver : nginx (with 260k bandwidth limit)I started converting videos with avconv and switched to ffmpeg because of this problems. But there was no success.
Meanwhile I tried all options for encoding but there are always the same problems with Firefox. Other videos play well but not mines and I don’t know why.Command :
