  • 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 streaming ip cam get delay from start record to first frame

    4 janvier 2019, par Vincent Carretero

    I’m recording stream from IP CAM with FFMPEG.
    I would like to know the exact timestamp when start the output video.

    Example :
    I have an output mp4 file created at 2019/01/04 09:10:15 (file created).
    FFMpeg take few seconds to really start streaming (initialising, etc...)
    The first frame really start at 2019/01/04 09:10:19 (just supposed, I would like to get this info).

    Thanks !

  • ffmpeg exact start and end times

    19 juin 2017, par Eng. M.Hamdy

    I’ve searched a lot but didn’t find what I nedd.
    I use this command :

    ffmpeg -ss <start> -i <srcfile> -t <duration> -c copy <dstfile>
    
</dstfile></duration></srcfile></start>

    to copy a part of the video, but the output file start time and duration may differ than "start" and "duration" specified.
    I understand that ffmpeg seeks to the nearest Keyframe and that precise seeking to a timestamp is not possible unless re-encoding the video (I tried that but the output video losses quality !).
    It’s important to me to know the exact start and end timestamp that ffmpeg use to generate the output, because I use this info to adjust subtitle timing.
    Is there any way to make ffmpeg report start timestamp and end timestamp ?
    Or else : Is there any way to know the previous and next keyframes to specific Timestamp, so I can adjust the video cut markers in my project to fit nearest keyframes ?
    Thanks.

    Update :
    - Is it possible to seek to the second keyframe, and to the keyframe before the last one ?
    - what is the time interval between 2 keyframes ?

  • PHP Sort Order Proccess Codeiginiter

    20 avril 2015, par Alan El-nino Malmsteen

    i use php codeigniter to manage video using FFMPEG, but i dont know how to delete original video after convertion succesful.

    if(!($_FILES["upload_video"]["type"] == "video/mp4"))
    
    {
    
    $prename = $r.'.'.$ext;
    
    $video = $prename.'.mp4';
    
    $directory_path  = "/home/templates/videos/".$prename;
    
    $directory_path_full = "/home/templates/videos/".$prename;
    
    exec("ffmpeg -i ".$directory_path_full." ".$directory_path.".mp4"); 
    

    
    // Delete original format video
    
    $this->load->helper("file");
    
    unlink($directory_path_full); 
    

    
    }else{
    
    $video = $r.'.'.$ext;
    
    }

    When i use "unlink" it work good to delete file, but the video is corrupt (maybe php directly delete it when converting progress)
    So, can you help me to create sort order php process for this case ?

    Thanks
