  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • recording video in real-time with OpevCV VideoWriter

    6 août 2023, par nick topper

    I have a few OpenCV projects that analyze video over USB, and in certain conditions must record the video stream to a file. People using my software complain that 10+ minute recordings yield video files that are about 20 seconds longer than they should be.

    



    I'm using openCV's VideoWriter. Iv'e tried things like setting CV2_CAP_PROP_FPS to a very low setting, and iv'e tried getting the average frame rate over a few seconds to find a good setting for my frame rate of the output file. Still not close enough to real time for my needs.

    



    Does anyone know of a good way to make sure my video is recording close to real time ? Should I use something like time.sleep (in python) to cap my framerate ? Or is there a better way to do this ?

  • Compression in Android taking long time

    24 avril 2017, par NSR

    I am new to Video related operations. I am using [FFMPEG][1] to compress a video in my Android application.

    I am trying to compress a video of 50MB to 10MB by executing following command

    ffmpeg -y -i /videos/in.mp4 -strict experimental -s 640x480 -r 25 -vcodec mpeg4 -b 150k -ab 48000 -ac 2 -ar 22050 /videos/out.mp4

    Video compressing successfully, but it taking more than 150 seconds. I am unable find out how to reduce that time.

    I want to change this command to complete this process in less time.
