@srouviere06 Tu peux ouvrir deux terminaux ?
Et faire un top sur le second.Soit c’est ralenti car il y a une conversion qui mange du CPU et tu peux essayer de supprimer la convertion.
Soit c’est parce que le Pi Zero W est déjà a fond.Donc il faut faire des tests …

-
@srouviere06 Si tu supprimes “-fps 30” c’est pareil ? ou pire ? ou mieux ?
-
Si tu regardes le format de ta video.
apt-get install exiftool exiftool nom.mp4Tu as quoi ?
-
L’idée est de faire une video au format idéal via ffmpeg.

Les fps c’est bon mais la résolution est plus grosse que necessaire.
Source Image Width : 640
Source Image Height : 360Toi tu dois avoir du 480 au max.
Donc ffmpeg.
Tu peux l’installer ? -
Ou alors chercher un mp4 en 480 .
-
-
c’est déjà installé
@srouviere06 La commande doit etre comme cela je pense.
ffmpeg -i LW3Org.mp4 -filter:v scale=480:-1 -c:a copy LW3Org-out.mp4Ensuite dans mplayer tu vires le scale
-
C.a.d.
mplayer -nolirc -noquiet -slave -identify -vo fbdev2:/dev/fb1 LW3Org-out.mp4 -nosound
