  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • -to value smaller than -ss error while clipping videos with ffmpeg

    16 mai 2018, par dusa

    I am trying to clip videos using frame information, I first convert the frame to time since ffmpeg uses this notion to clip videos.

    The problem is for shorter videos, it gives the error :

    -to; value smaller than -ss; aborting.

    But in reality, this is false. For example, I get an error even with these values :

    0:0:47.4 -to 0:0:47.21  (format -> hh:mm:ss.frame)

    Can anyone tell me how I can fix this ?

    The video frame rate is 25 fps and the command structure I use is :

     os.system('ffmpeg -i ' + inputvideo + '.mp4' + ' -qscale:v 2 -vf scale=427:240 ' + ' -ss '+ str(fhours) + ':' + str(fminutes) + ':' + str(fseconds) + '.' + str(fframes) + ' -to ' + str(lhours) + ':' + str(lminutes) + ':' + str(lseconds) + '.' + str(lframes) + ' ' + outputvideo + '.avi')

  • What is the best way to stream live video from OpenCV to browser (native codecs) ?

    29 avril 2017, par trojek

    I have a webcam and I get a video to OpenCV, then I want to stream modified video to the browser.
    Currently, I’m using jsmpeg which works well for low video resolutions.

    On this page I found the list of codecs which are natively supported by Safari, Chrome, Firefox, Opera and IE browsers. For example, H.264 is supported by above browsers.

    How can I prepare stream from OpenCV, GStreamer or FFmpeg in order to get live streaming ?

  • Live streaming dash content using mp4box

    15 mai 2017, par galbarm

    I’m trying to live stream H.264 content to HTML5 using the media source extensions API.

    The following method works pretty well :

    ffmpeg -i rtsp://10.50.1.29/media/video1 -vcodec copy -f mp4 -reset_timestamps 1 -movflags frag_keyframe+empty_moov -loglevel quiet out.mp4

    and then :
    mp4box -dash 1000 -frag 1000 -frag-rap out.mp4

    I can take the MP4Box output (out_dashinit.mp4) and send it through Web Sockets, chunk by chunk, to a JavaScript client that feeds it to the media source API.

    However, this is not a good method for live content.

    What I’m trying to do now, is to create a single pipeline in order to do it in realtime and with the minimum possible latency.
    With FFmpeg it’s possible to redirect the output to stdout instead of out.mp4 and grab the content.
    I couldn’t figure out if it’s possible to combine MP4Box into the pipeline.

    1. Can MP4Box take the input data from a source which is not a file ?
    2. Can MP4Box grab such a content progressively (either from a file or other source) while it is arriving in realtime ? i.e. wait a little if stream stops for 1 sec and resume automatically.
    3. Same question but for the output : can it output to something which is not a file (such as stdout) and can it do so progressively so that whenever output data is ready, I will be able to take it and transfer it to the web client, essentially generating a never-ending dashed MP4.
