  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Revert "configure : Stop using dlltool to create an import library"

    16 février 2018, par Martin Storsjö
    Revert "configure : Stop using dlltool to create an import library"

    This reverts commit 67c72f08a4707c18a67a4734660e3a23cc9488b6.
    

    While the linker produced import libraries might work with MSVC in
    
simple test cases, they don't if e.g. linking to multiple GNU ld
    
produced import libraries at the same time. (They end up importing
    
functions from the wrong libraries.) The ones produced by dlltool
    
work fine though.
    

    This issue was pointed out by Hendrik Leppkes.

  • Why does ffmpeg stop recording at midnight ?

    22 septembre 2019, par peter

    I have a shellscript like this under Kubuntu 19.10,

    #!/bin/bash
    

    
while true
    
do
    
    FILE=/media/petermc/Security5/Camera2/Camera2_.mp4  
    
    FILE=${FILE%.*}`date +%Y-%m-%d_%H-%M-%S-%N`.${FILE#*.}
    
    echo $FILE
    

    
    ffmpeg -rtsp_transport tcp -t 00:15:00 -i rtsp://*user*:*password*@192.168.1.60:554/ch02/0 -c copy -map 0 $FILE
    
done

    It records files like this,

    Camera2_2019-09-21_23-36-57-874602376.mp4
    
Camera2_2019-09-21_23-51-57-876639147.mp4

    Basically recording 15 minutes at a time from the RTSP feed, then starting a new file.

    However it stops working at midnight, the last few lines from the log file are this,

    frame= 3987 fps= 13 q=-1.0 size=  117760kB time=00:05:06.51 bitrate=3147.3kbits/s speed=1.01x    
    
frame= 3994 fps= 13 q=-1.0 size=  118016kB time=00:05:07.07 bitrate=3148.4kbits/s speed=1.01x    
    
frame= 4001 fps= 13 q=-1.0 size=  118016kB time=00:05:07.59 bitrate=3143.1kbits/s speed=1.01x    
    
frame= 4008 fps= 13 q=-1.0 size=  118272kB time=00:05:08.11 bitrate=3144.6kbits/s speed=1.01x

    So there doesn’t seem to be any error, it stops recording at 5 minutes into the last file with no error.

    Another piece of information is that I have 6 cameras, and 4 stopped recording, the ones connected to a DVR. I have a couple of IP cameras and they kept recording.

    What could be the cause of this ? Plus, what else could I do to work around this or diagnose this ?

    UPDATE :

    I believe the issue is because the DVR has a maintenance setup to restart once at week at midnight. If this is what happened, is there any way I can configure ffmpeg to restart if it has lost the stream ?
