  • Récupération d’informations sur le site maître à l’installation d’une instance

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Split video file from 'n' th frame to end of video in Linux

    17 novembre 2011, par Skkard

    I need to split a video file using frames as the measure, e.g. I need to save the part of the video from the 34th frame to the end of the video in Linux( specifically fedora 16, xfce, 64bit ).

    I've tried using ffmpeg, using the '-vframes' option to specify how many frames to save, but it starts from the beginning, so is not that useful. How can I start from a certain frame in between the video and save the video from there to the end in a new file.

    I know about the '-ss' option, but while converting number of frames to the specified time, there might be errors( or so I believe. Please correct me if I'm wrong ) due to rounding.

    Could you please suggest a method ? Thanks !

  • How to extract video clip from larger video based on specific time and duration

    26 juillet 2022, par user19019404

    I have video clips that get created. Each video is recorded for 5 minutes and starts at a time e.g. 10:01:20 to 10:06:19 then the next video from 10:06:20 etc. These videos are recorded at a specific frame rate, be it 5 frames or 30 frames (its dependent on the platform making the recording). The net result is NOT a 5 minute video clip but might be a 2 minute video clip (where everyone moves very quickly in the view as a result of the frame rates). I cannot restrict a 1 to 1 recording as these are generated by external systems.

    


    I need to extract specific portions out of the video. For example I need to extract from 10:03:10 to 10:03:35 (25 seconds). This would equate to 10 seconds into the video up to 14 seconds into the video, in those 4 seconds of video, 25 real world seconds are displayed.

    


    My question is do you have any guidance as to how I can calculate that each second of recording actually means 10 or 12 seconds in real life, therefore go to this frame and record to this frame for example.

    


    I have been looking at cv2.CAP_PROP_FPS to get the video frame rates, CAP_PROP_POS_MSEC and CAP_PROP_FRAME_COUNT and believe the answer might lie there, but not sure.

    


    The thinking being if I work out the frame rate of the video, the total frames then I can divide the one by the other to get to how many frames make up real world seconds (this is where I fail). This way I can run from frame to frame as a result.

    


    Thank you

    


  • RTMP video streaming client without showing the video just need extensive log

    6 août 2016, par Amir

    I set up an RTMP video streaming server in a cloud environment for research purposes. On another VM in the cloud, I want to use a client to do some experiments. I have tried some different video player like VLC and FFplay but they are keep playing the video in the shell. As it is in the command line environment and to make sure my experiments are not biased with human errors, I need an RTMP video streaming client that just receives the stream as if it wanted to play it and log everything, for instance, if the playback stops due to buffering, average buffer size, etc.

    Thanks
