Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

How to deal ffplay bein too slow playing iPhone's videos ?
21 janvier 2019, par Mikhail T.Trying to play a 3840x2160 video recorded by an iPhone 7 (@30fps), I get frequent pauses — in the video, music keeps playing.
This happens both in firefox and when
ffplay
is invoked to play the file directly — from command-line. The CPU is a dual E6700 @3.20GHz — not super fast, but it should be able to play smoothly, shouldn’t it ? Video is Intel’s "series 4" integrated chipset — again, not a speed-daemon, but it should be adequate... Support for Intel’s VA API is included.I build ffmpeg-4.1 from source using FreeBSD port. As you can see, the port has a maddening amount of options — including several different ones for the 264-codec.
Any suggestions for improving the decoding speed to the point, where it is watchable by a human ? Thank you !

If you rotate the iPhone's video with ffmpeg, the rotation information sticks. Can I hide this ?
24 août 2017, par howmanylifeThe following implementation is a command to rotate the movie by 90 degrees.
ffmpeg -i video.mp4 -vf transpose=1 -metadata:s:v:0 rotate=0 videoo.mp4
-vf transpose=1The iPhone’s video contains rotation information and actually
ffprobe -show_streams -print_format json videoo.mp4 2>/dev/null
To output motion picture information or rotation information as described below.

},

"rotation": -90
}
]
"rotate": "90",and

Is it possible to hide this ? Or is it possible to erase only this rotation information ?
