Mencoder, encodage vidéo en ligne de commande
Mencoder est un outil en ligne de commande. Il fait parti intégrante de Mplayer. Mencoder est capable de convertir à peu prés tous les formats vidéo. A ma connaissance, il s'agit de l'encodeur le plus complet. Je met en ligne les lignes de comande que j'utilise le plus souvent. Cette doc est donc loin d'être exhaustive. Pour plus de détails, consultez la doc officielle
Installation
MPlayer/Mencoder est disponible pour plusieurs plateforme. Consultez la section download du site officielle

Utilisation et Encodage vidéo avec mencoder
Considérons la conversion d'un fichier .ts (Format vidéo d'enregistrement sur FreeBox).
Remplacer .ts par votre format de fichier (wmv,mpeg, ...).
Vous pouvez modifier la valeur de vbitrate pour diminuer la taille du fichier obtenu (vous perderez en qualité ...).

Il existe plusieurs logicil sous Windows (Et plus encore sous Linux) qui permettent d'obtenir des informations sur un fichier Vidéo.
Ci-dessous, l'exemple du logiciel mediainfo:
| Conversion en mpeg4 avec codec de la famille lavc |
Commande:
mencoder -oac mp3lame -lameopts cbr=128 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1000:aspect=16/9 Final-Rolland.ts -o Finale-Roland.avi
| Conversion en divx avec codec xvid |
Commande:
mencoder -ffourcc XVID -oac mp3lame -lameopts cbr=128 -ovc lavc -lavcopts vbitrate=1000:aspect=16/9 -of avi -srate 48000 -af lavcresample=48000 -fps 25 -ofps 25 -o Final-Rolland.avi Final-Rolland.ts
| Encodage de qualité supérieur en 2 passes avec codec X264 (HD) |
Commande:
in=original.ts outputfile=fichier.x264.avi bitrate=2048 mencoder "$in" -o /dev/null -ovc x264 -x264encopts "bitrate=$bitrate:frameref=8:mixed_refs:bframes=3:b_adapt:b_pyramid:weight_b:partitions=all:8x8dct:me=hex:subq=5:trellis=2:threads=auto:pass=1" -vf pp=li -nosound mencoder "$in" -o $outputfile -ovc x264 -x264encopts "bitrate=$bitrate:frameref=8:mixed_refs:bframes=3:b_adapt:b_pyramid:weight_b:partitions=all:8x8dct:me=hex:subq=5:trellis=2:threads=auto:pass=2" -vf pp=li -oac mp3lame -lameopts cbr=192
Utilisation des profiles avec mencoder
Les lignes de commandes mencoder sont souvent super relou !!!
Heuresement, il existe un moyen simple de contourner cela : Les profiles
| Example de profile mencoder (copier les lignes suivantes dans le fichier .conf de mencoder): |
[mpeg4] profile-desc="MPEG4 encoding" ovc=lacv=yes lavcopts=vcodec=mpeg4:vbitrate=1200 [mpeg4-hq] profile-desc="HQ MPEG4 encoding" profile=mpeg4 [HD1] ovc=x264 x264encopts=bitrate=$bitrate:frameref=8:mixed_refs:bframes=3:b_adapt:b_pyramid:weight_b:partitions=all:8x8dct:me=hex:subq=5:trellis=2:threads=auto:pass=1 oac=nosound o=/dev/null vf=pp=li [HD2] ovc=x264 x264encopts=bitrate=3000:frameref=8:mixed_refs:bframes=3:b_adapt:b_pyramid:weight_b:partitions=all:8x8dct:me=hex:subq=5:trellis=2:threads=auto:pass=2 oac=mp3lame lameopts=cbr:br=192 vf=pp=li [NOHD] ovc=xvid xvidopts=bitrate=1000:trellis:me_quality=6:vhq=2 oac=mp3lame lameopts=br=192:aq=0
| Reste plus qu'a lancer: |
Commande:
mencoder.exe -profile=HD1 FichierSource.WMV mencoder.exe -profile=HD2 FichierSource.WMV -o FichierDest.AVI ou encore mencoder -profile=mpeg4-hq toto.wmv -o toto.mpg mencoder -show-profile
Décalage son et vidéo
L'option -audio-delay , retarde le son
ou la vidéo en définissant le champ délai.
Par exemple, si une vidéo est jouée correctement par
mplayer avec -delay 0.2, alors vous pouvez corriger la
vidéo avec MEncoder avec -audio-delay -0.2
(Noter bien l'opposé 0.2 et -0.2 !!!)
Pour le moment, cette option ne fonctionne qu'avec le
multiplexeur par défaut (-of avi).
Si vous utilisez un multiplexeur différent, alors vous
devez utiliser -delay à la place.
On recherche d'abord le décalage son/vidéo avec
mplayer (délai en secondes):
mplayer -delay -0.2 mavideo.avi
Procédé par dichotomie pour trouver la bonne valeur du décalage. Ensuite, il suffit de lancer la commande mencoder pour supprimer le décalage son/vidéo :
mencoder -of avi -oac copy -ovc copy -audio-delay 0.2 mavideo.avi -o mavideo_ok.avi
