Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

ffmpeg : images to 29.97fps mpeg2, audio not sync [migrated]
21 novembre 2011, par Andy LeI have spent a lot of time on this issue. Hope someone can help.
I want to convert 3147 images + ac3 audio file into an mpeg2 video at 29.97fps (about 1m45s). My command :
~/ffmpeg/ffmpeg/ffmpeg -loop_input -t 105 -i v%4d.tga -i final.ac3 -vcodec mpeg2video -qscale 1 -s 400x400 -r 30000/1001 -acodec copy -y out.mpeg 2> out.txt
However, the audio file ends before the frame sequence. Which means the video is slower then audio.
I checked the output file with imageinfo and see :

From YUV to Y4M ffmpeg adapting
14 janvier 2014, par roberutsuI was used this command to convet some YUV videos in m4v, note that I was using a video in CIF format :
ffmpeg -s cif -r 30 -i video.yuv -vcodec mpeg4 -g 30 -bf 2 -sameq video.m4v
Now I downloaded a 720p movie and want to have the same paramethers
ffmpeg -r 30 -i video.y4m -vcodec libx264 -g 12 -bf 2 -sameq video.m4v
I erased "-s cif" because I read that the headers in y4m already have the resolution.
I'm getting the error "frame hate not found". -
FFmpeg - C - Encoding video - Set aspect ratio
22 août 2013, par KnossosI am decoding a video from mp2 and encoding to mp4.
The original file :
Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p, 720x576 [SAR 64:45 DAR 16:9]
The resulting file :
Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p, 720x576 [SAR 1:1 DAR 5:4]
As you can see, the resolution has not changed, but the aspect ratio has.
My question, is how can I set these values (SAR and/or DAR) ?
