  • 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 (...)

  • FFmpeg subtitle filter set start time

    31 décembre 2020, par CasualDemon

    I am trying to burn-in subtitles for a shorter section of a video, but using the subtitles filter always starts from the beginning of the subtitle stream, not at the specified start time, even when copying from the same video.

    


    So for example if I start an encode 10 minutes in to a film, the video will properly be set from there, but the subtitles will start from the beginning (10 minute offset in this case).

    


    ffmpeg -y -ss 600.0 -to 660.0 -i movie.mkv -filter_complex "[0:0]subtitles='movie.mkv':si=1[v]" -map "[v]" -c:v libx265 -crf 22 output.mkv


    


    This is not a problem when using picture based subtitles and the overlay filter, such as :

    


    -filter_complex "[0:0][0:2]overlay[v]"


    


    It seems to only affect text based subtitles. I don't know if this is just not possible and will require another solution, or if I am approaching it wrong. Any help is appreciated !

    


  • ffmpeg output file is too large

    6 juin 2017, par David Page

    I want to burn a subtitle file(.srt) to a mp4 video.My command is :

    ffmpeg -i input.mp4 -c:v mpeg4 -q:v 1 -vf subtitles=input.srt out.mp4

    It output a video with a good quality,but its size is 1.12GB while the input file is 213MB.

    I think the problem is kbps of output file is too high.the bitrate of input file is 568 kb/s but the output file is 3154 kb/s.

    So I want to set the kps,now here is my code :

    ffmpeg -i input.mp4 -b:v 569k -minrate 568k -maxrate 570k -c:v mpeg4 -q:v 1 -vf subtitles=input.srt out.mp4

    Although the output file become smaller(538MB),the video’s quality is awful(Compare with input file)...
    So how to make the output file smaller and in good quality ?Thanks.
