Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -

FFMPEG reports invalid video resolution, video headers container seem to be different from actual frames !
20 décembre 2011, par EmilianoQuick question, i have a movie, which was cut and rendered with Sony Vegas from its original format to a .wmv file. Here comes the tricky part, movie when played, either with
VLC
orWMP
, has a resolution of 656x480 ... BUT when i run a ffmpeg -i on it, it says it has a resolution of600x480
....I took the time of actually capturing a frame and croping it with photoshop and its
656
and not600
like ffmpeg its reporting, why would this could be happening ? How could i fix the headers resolution ? Would that have any impact on video re-rendering ? As i said, VLC and WMP seems not to care about the incorrect headers and are playing it right, BUT, jwplayer seems to be using the header information, which i don't blame him, its correct to do that, but why the video headers could be wrong ?ffmpeg -i trailer.wmv
Input #0, asf, from 'trailer.wmv' : Duration : 00:01:04.93, start : 3.000000, bitrate : 2144 kb/s Stream #0.0 : Audio : wmav2, 44100 Hz, mono, 32 kb/s Stream #0.1 : Video : wmv3, yuv420p, 600x480 [PAR 59:54 DAR 295:216], 2065 kb/ s, 25.00 tb(r)
And yeah, the
PAR/DAR
parameters are also wrong, but honestly, i don't understand that technical shit, usually watch video and make sure it look good, any feedback would be appreciated :PIs there a way to change the container information with ffmpeg so applications that actually do use the container information don't render video incorrectly ?
