  • 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 (...)

  • Converting imges to video

    19 janvier 2014, par DanM

    I am using external camera with my application. The camera takes 9 pictures every second (9fps). The pictures are bitmaps 384x288. I need to create from this pictures a video file.

    What I have tried :

    • Using Jcodec

    The problem : jcodec is relatively slow, and for it to work properly i add the bitmaps to ArrayList and when the record stopped i convert the array to video. I takes to much time. For 30 sec video there is about 1 min rendering time.

    • Using native mediaCodec

    The problem : I could only generate AVI files (video/avc) that not readable in the original android player. I can not use what is written here : http://bigflake.com/mediacodec/ because I developing for API 16. I have tried using (video/mp4v-es) but the video is corrupted and not playable in any player.

    • Using FFmpeg

    The problem : Very complicated to implement in android, and I am not sure it will give me the result I needed after spending time to implement this. The result I need is to record video streaming as I get the bitmap without any delay.

    What can you suggest me ?

  • How can i create a stable checksum of a media file ?

    19 février, par yawniek

    how can i create a checksum of only the media data without the metadata to get a stable identification for a media file. preferably an cross platform approach with a library that has support for many formats. e.g. vlc, ffmpeg or mplayer.

    



    (media files should be audio and video in common formats, images would be nice to have too)

    


  • How to generating waveform from video & show it with video

    25 novembre 2016, par Salil

    We are using Rails as a backend & AngularJS on Front End side in my App where we need to show Video & audio waveform of that video.

    We are using ’wavesurfer.js’ to show the waveform on Front End side & ’node-pcm’ to generate pcm from video file on BackEnd side.

    This is working as expected but in some of the videos while creating waveform from pcm data instead of showing small sine waves we get flat line.
    Also it takes too much time to show the waveform for every page reload.

    To overcome this issue we are planning to create waveform image using ffmpeg

    ffmpeg -i 'https://s3.amazonaws.com/aadasdsadsadasdas/xyz.mp4' -filter_complex showwavespic -frames:v 1 output.png

    This is working fine but it also takes too much time (Ofcourse only once ) to generate the image for remote video (i.e. We are saving videos on S3)

    Problem with this i don’t get any library to integrate the waveform image with the Video.

    Can someone suggest any better approach related to this.
