  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 24 cores, 25 ffmpeg session - cpu looks good but load average high

    9 août 2012, par thevoipman

    I don't know if it's my script or just the system itself, but I definitely don't want to take anything down.

    I am running a centos 6.3 64bit with about 25 sessions of ffmpeg encoding

    1. I am trying to speed up ffmpeg encoding, but it seems like whatever ram or cpu I have, the encoding process still take very long. I have used -threads 0 or even -threads 16 to see if it speed up but it doesn't.

    2. My load average is very high, how can I lower this without terminating ffmpeg tasks ?

  • Getting log line for each extracted frame from FFMPEG

    3 février 2016, par wpfwannabe

    I am using FFMPEG.exe to extract frames from various videos. As this is a programmatic solution and getting the total frame count and/or duration can prove tricky (with ffprobe), I am thinking I could use the console output to detect individual frames’ timestamps but I am getting a single output line every N frames like this :

    frame=   20 fps=0.0 q=0.0 size=       0kB time=00:00:01.72 bitrate=   0.0kbits/s
    
frame=   40 fps= 38 q=0.0 size=       0kB time=00:00:04.02 bitrate=   0.0kbits/s
    
frame=   60 fps= 39 q=0.0 size=       0kB time=00:00:06.14 bitrate=   0.0kbits/s
    
frame=   70 fps= 38 q=0.0 Lsize=       0kB time=00:00:07.86 bitrate=   0.0kbits/s

    Is there a command line option to force output for each and every frame ? If so, I could extract the time= portion. This is the command line currently used :

    ffmpeg.exe -i video.avi -y -threads 0 -vsync 2 %10d.jpeg

    Ideally, replacing %10d.jpeg with some other format that writes frame’s timestamp but I don’t think this exists.

  • ffmpeg keyframe extraction

    26 septembre 2012, par Shikhar Shrivastav

    I have been trying to extract keyframes from video using ffmpeg 0.11.1 . So far all the commands I have tried do not extract keyframes but return all the frames ie 25fps*total time number of frames in the output.
    I tried setting the keyint_min as 25 to make sure there is a amximum of 1 keyframe per second.

    ffmpeg -vf select="eq(pict_type\,PICT_TYPE_I)" -g 250 -keyint_min 25 -i C:\test.mp4 -vsync 2 -f image2 C:\testTemp\thumbnails-%02d.jpeg

    But still all the frames are returned.

    Then i tried, to separate the keyframes by 20 seconds.

    ffmpeg -i C:\test.mp4 -vf select='eq(pict_type\,I)*(isnan(prev_selected_t)+gte(t-prev_selected_t\,20))' -vsync 0 -f image2 C:\testTemp\%09d.jpg

    Again same result, all the frames are returned.

    What should I do ?
