    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 (...)

    I am trying to use qt-faststart on MP4 videos to make the streaming fast but the qt-faststart command is never get finish, It is running from the last one and half hour and video file is of 14MB only.

    The command is showing the ftyp and free as output

    the output look like this

    The MP4 video is converted from FLV video using the FFMPEG.

    Generally it show the output like this but with my installation of qt-faststart I never get this ouput

  • How to insert bullet screen comments into a video by using ffmpeg ?

    7 septembre 2019, par Saeron Meng

    I would like to add some real-time comments in my video but I do not know how to use ffmpeg to realize this. The comments are like screen bullets through the screen, scrolling from right to left.

    My thought is to count the length of the comments and define speeds for them to move. Don’t worry about the source of the comments, I have already gotten them saved as an xml file. Also, I can transfer it into srt. For instance :

    <chat timestamp="671.195">
    
    <ems utctime="1562584080" sender="Bill">
    
        <richtext></richtext>
    
    </ems>
    
</chat>
    
<chat timestamp="677.798">
    
    <ems utctime="1562584086" sender="Jack">
    
        <richtext></richtext>
    
    </ems>
    
</chat>

    The final result is like this (I did not find an example displayed in English), these fancy characters can move horizontally :

    example

    I have searched some solutions on the Internet, most of which talk about how to write ass/srt files and add motionless subtitles. Like this :

    3
    
00:00:39,770 --> 00:00:41,880
    
When I was lying there in the VA hospital ...

00:00:42,550 --> 00:00:44,690
    
... with a big hole blown through the middle of my life,
    

    
5
    
00:00:45,590 --> 00:00:48,120
    
... I started having these dreams of flying.

    ffmpeg -i infile.mp4 -i infile.srt -c copy -c:s mov_text outfile.mp4

    But I need another kind of "subtitles" which can move.

    So my question is, how to modify the ffmpeg command and the template of srt file so as to arrange the subtitles from the top to the bottom and let them move from right to left ?

    checkasm : x86 : post commit review fixes

    Check the full FPU tag word instead of only the lower half and simplify
    
the comparison.
    
Use upper-case function base name as macro name to instantiate both
    
checked_call variants.
