1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

ffmpeg convert 4K file to 1080p mp4 file
16 septembre 2015, par Hüseyin GÖZEi’m using ffmpeg to converting video in windows service, when i’m trying to converting 4K video to 1080p ffmpeg returns error like this :
libvo_aacenc Stream mapping : Stream #0:0 -> #0:0 (h264 (native) ->
h264 (libx264)) Stream #0:2 -> #0:1 (ac3 (native) -> aac
(libvo_aacenc)) Error while opening encoder for output stream #0:1 -
maybe incorrect parameters such as bit_rate, rate, width or heightmy ffmpeg convert command like this :
ffmpeg -i 4k2.mp4 -vf scale=1920:1080 -threads 3 4k2_1080.mp4
what’s wrong with this ?

check video actual resolution, not from metadata, on ubuntu
7 juillet 2015, par coral chenI need to check the dimension of a video. When I check its properties on Ubuntu 14.04, it shows 1920*1080, which is correct. However when I check it using ffmpeg, it shows 640*480 and PAR 1:1, which is set incorrectly in metadata.
How can I find out the actual dimension the video display without changing the metadata (since there are a lot of video like this) ? Or if anyone can explain how Ubuntu default video player can read it correctly ?
