  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Best solution to automatically enrich a video stream with dynamic overlay (text, images, ...)

    17 novembre 2016, par hg.m

    In my company, we are currently looking for a solution to enrich a given video stream (which is being broadcasted via RTMP) from a remote webcam with dynamic information, such as current date/time, special measure values which are available on a server or the most recent entries in a database. Basically we want to achieve a simple, dynamic on-screen display as, for example, TV stations are using. The modified stream should then be restreamed, for example to be viewed in VLC Player or on YouTube.

    So far, I came up with the following ideas :

    • Using OBS with some own scripts and plugins - that’s disadvantageous because we would like to run the solution on a high-network performance server 24/7 without a GUI. Basically I’d need a fully command-line based version of OBS.

    • Using ffmpeg : I know that there are text filters available, but they are mainly static (or periodically polling a file with text) and don’t allow for any design adjustments other than font, font size and color. It would be great if there was some way of overlaying a Webkit browser view onto the stream, because this would allow us to design the overlays in HTML5 and CSS and using WebSocket technology for updating the data.

      • The overlay could be captured with PhantomJS, but how should we unify it with the stream and would it be fast enough to render 30 FPS ?

    Are there additional (preferably open source) tools we could use ? What would be the best strategy to implement this without buying expensive TV broadcasting software ?

  • 【CV】use ffmpeg to process video through cmd in python

    26 novembre 2019, par user66124

    when reading the segment generation function in https://github.com/zhengshou/scnn, I encounter the following sentence :

    cmd = '../lib/preprocess/ffmpeg -i ' + input_video + ' -r ' + str(framerate) + ' -f image2 ' + framedir + videoname +'/%06d.jpg' + ' 2>' + framedir + 'frame_extract.log'

    Is there anyone know the meaning of each part ?
