  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • Recording desktop with gdigrab ffmeg to mp4 file with too high video_size don't working

    22 septembre 2021, par tagry

    I try to recording my desktop with ffmpeg using the command :

    



    ffmpeg -f gdigrab -framerate 10 -video_size 1920x1200 -i desktop -pix_fmt yuv420p -vcodec libx264 -preset ultrafast output.mp4


    



    The problem is when the video_size option is higher than some size, (for example height higher 1089), the video can't be read with Windows Media. I noticed that with this high size, the video which be recorded doesn't have informations about size. I don't understand why the record don't work with a too big size. If somebody can help me. 
Thank you very much and very sorry for my English.

    



    [edit]

    how to remove duplicated frame from 00:00:00,00 to 00:00:00,25 (00frame 25frames)section not overall with mpdecimate filter ??
    normally H264 video have some duplicated frames on video start section ..

        i have tried like this , 
    

    
1)  ./ffmpeg -i cated_2-3.UMMJI.MTS -map 0:0 -c:v prores_ks -profile:v 1 -qscale:v 8  -s 1920x1080  -r 29.97  -top 1  -c:a pcm_s16le    -map 0:1 -filter:a:0 "pan=mono|c0=c0" -map 0:1 -filter:a:1 "pan=mono|c0=c1"   -metadata:s encoder="Apple ProRes 422 LT"  -filter_complex "[0]split=2[a][b];[a]trim=end_frame=26,mpdecimate[a];[b]trim=start_frame=25,setpts=PTS-STARTPTS[b];[a][b]concat=n=2:v=1:a=0" -vsync vfr -vf blackdetect=d=0.1:pix_th=.1  cated_2-3.UMMJI_MTS_mpdecimate26_section.mov
    

    
and  tried to check black_frame on out prores mov file 
    
2)./ffmpeg  -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov  -vf blackdetect=d=0.1:pix_th=.1  test.mov
    

    
then , will be shown like below

[out#0/rtsp @ 00000178486d9a00] Codec AVOption b:a (set bitrate (in bits/s)) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some decoder which was not actually used for any stream.

    This is were the output stopped, instead of reading the video frame by frame, it stops here and runs indefinitely. I tried to use VLC and python script to read the rtsp url, but that didn't work.
I tried the alternative using GStreamer, but i couldn't install rtsp-server on Windows 11.

    


    Thank you for your time, any suggestion or answers are appreciated. The end goal is to convert a video to a rtsp url.
