  • 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.

  • How do VLC and ffmpeg work together ?

    18 juillet 2019, par Toufik Moad

    I compiled VLC from the source code and it works well. When I do ". / Vlc" vlc runs. I also compiled ffmpeg from source and it works well too. When I do "ffmpeg-i-f toto.flv mp3-vn-acodec copy new_toto.mp3", the file named "new_toto.mp3" is generated.
    What I cannot understand is how VLC and ffmpeg work together ? What part of VLC code uses ffmpeg code ?

    Is there a ffmpeg command to play (read) a video ?

  • A video player based on QtAV with Direct2D / OpenGL rendering

    22 juin 2015, par ashikthomas

    I’m developing a video player in Qt C++ using QtAV. QtAV uses ffmpeg internally. I need to show semi transparent overlays both my watermark logo and subtitles. I’m writing the application for windows. I use OpenAL library. OpenGL and Direct2D are the choice for renderers.

    If I use OpenGL renderer, it works fine in some systems. The overlay works fine. But in some other systems the whole application will be just a black window. Nothing else I can see.

    If I use Direct2D, the overlay wont work. And the renderer is a bit slow. But it works on all systems, without this overlays.

    I have no code to show here because its not the coding issue. Even the examples in QtAV are not working. I need to find a way to show the overlays using Direct2D renderer OR find a solid way to use OpenGL rendering on all systems without fail.

  • Why does not work audio element currentTime on ffmpeg encoded mp3 file in Chrome browser

    25 juillet 2013, par Peter

    I have an HTML5 audio element :

    <audio preload="auto">
    
    <source src="./Sound/recording.mp3" type="audio/mpeg">
    
</source></audio>

    and I need to be able to play last 4 seconds from mp3 recording. My javaScript is :

    audio.currentTime = audio.duration-4;
    
audio.play();

    Works ok in IE10 and Firefox, but Chrome starts playing from a wrong place. The difference between reported audio.currentTime and actual playback position is about 20s. The recording.mp3 is created with ffmpeg :

    ffmpeg -i recording.wav -ab 32k recording.mp3

    It works, when I strip the ID3v2 header from the recording.mp3 (deleting the first couple bytes in the file before the audio data).

    It also works when I compress to ogg. Can somebody point me to the right direction (ffmpeg switches, audio element attributes or whatever) to get it work also in chrome ?

    Thanks in advance
