  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • ffmpeg - splitting, overlaying and selecting frame range in multiple input/outputs with complex video filter producing empty output

    11 octobre 2017, par Josep Carner

    I am trying to use ffmpeg to apply multiple filters -single input, multiple outputs-. In concrete, I am splitting the output in two, then applying an overlaying patch to one of those streams, split again and select a time range. The command I am using is :

       ffmpeg \
    
    -i ./dataset_test/videos/jz_10_huron_barstow.mkv \
    
    -an \
    
    -sn \
    
    -loglevel error \
    
    -filter_complex \
    
        "[0:v]split=2[L_in][F_in];
    
         [L_in]
    
            crop=226:307:21:74,scale=200x200,setdar=200:200,split=2\
    
         [L_in_0][L_in_1];\
    
         color=#808080:226x307,setpts=PTS-STARTPTS[L_PATCH];\
    
         [F_in][L_PATCH]
    
            overlay=21:74:shortest=1,scale=200x200,setdar=200:200,split=2\
    
         [F_in_0][F_in_1];\
    
         [F_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_0];\
    
         [F_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_1];\
    
         [L_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_0];\
    
         [L_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_1]\
    
         "\
    
    -map [F_0] -an -sn ./out/jz_10_huron_barstow/F/0_F.mp4\
    
    -map [F_1] -an -sn ./out/jz_10_huron_barstow/F/1_F.mp4\
    
    -map [L_0] -an -sn ./out/jz_10_huron_barstow/L/0_L.mp4\
    
    -map [L_1] -an -sn ./out/jz_10_huron_barstow/L/1_L.mp4\

    For some reason, 0_F.mp4 is empty and 1_F.mp4 is cropped. My intuition is that it has something to do with applying splitting + overlaying + selecting. I think at some point some filter before select is changing the PTS of the frames in some way select is not properly discarding them, but I honestly don’t know how to solve it. Some insights :

    1. L_0 and L_1 are fine (no overlay is used in those two)

    2. If I suppress L outputs everything works fine (no "split" is needed at the beginning)

    Could someone provide some light ? I don’t really know what else to try.
    The logs with loglevel 40 are (some repeated lines ommited) :

  • The C++11 Thread Timer is not working

    26 août 2017, par Gathros

    I’m trying to make a video player using SDL2 and FFmpeg API. The video is being decoded and I can display an image on screen. I can also play audio but I not doing that (I know it works, I’ve tried it).

    My problem is I can’t update the image when it should be. I’m able to get the timestamps and work out the delay then send it to a thread, where it should call an window update when the time has elapsed. But all that happens is the images flash on the screen with no delay. I have even set the delay to 1 second and the images still flash, after there being 1 second of a blank window.

    Here is my code :

  • where to put the watermark png file in this code ?

    15 août 2017, par asif

    this is a line from ffmpeg video converter php script ;

    $ffmpeg." -i ".$video_to_convert." -vcodec flv -f flv -r 30 -b ".$quality."-ab 128000 -ar".$audio." -s ".$size." ".$converted_vids.$name.".".$new_format."

    where :

    .$video_to_convert. = input file

    .$converted_vids.$name. = output file

    .$new_format. ; = file extention format

    now i want to add watermark.png file, if i put any where i got error conversion
    as i added the line logo.png -filter_complex 'overlay in video quality line, i got error

    Error ;
