  • MediaSPIP Player : problèmes potentiels

    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
    Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

  • Get rotation information from javacv ffmpeg FrameGrabber

    9 février 2015, par pept

    I am using FFMPEG from the JavaCV library to extract all pictures of a movie (solution found here : How can I get a frame sample (jpeg) from a video (mov)). This is my code which works fine :

            grabber.start();
    
            int size = grabber.getLengthInFrames();
    
            for (int i = 0; 0 < size; i++) {
    
                File destination = new File(directory, i + ".png");
    
                if (!destination.exists()) {
    
                    ImageIO.write(grabber.grab().getBufferedImage(), "png",
    
                            destination);
    
                }
    
                setProgress((int) ((float) i / size * 100));
    
            }
    
            grabber.stop();

    However, the pictures are rotated by 90 degrees when I extract them. The output in command line after grabber.start() ; contains the following lines :

     rotate          : 90

    and

     displaymatrix: rotation of -90.00 degrees

    which indicates that it detects the rotation.

    My question is : How can i programmatically get the rotation to rotate them back myself or a way to get the normalized picture with the library ?

  • ExoPlayer and deinterlacing feature

    21 février 2021, par Suppaman

    I want to use ExoPlayer to show interlaced video but, especially for SD content, the video looks really bad without any deinterlacing feature. Looking in the ExoPlayer project it seem the player doesn't have such deinterlacing feature and doesn't seem in plan to be added. I'm thinking to try add deinterlacing by using the deinterlacing engine of ffmpeg library. However it don't seem and easy task. I found some projects that could help me like this ExoPlayerFilter that apply a filter on the frame before show. This could be a possible way to "deinterlace" the frame before show. Another possible suggestion comes from the tread in github Exoplayer project here. This could be another possible way to proceed. My problem is that I have a limited time to try add this feature and I would to know from people having more experience than me what would be most "suggested" way to follow or if someone know another better way to reach my results.

    


    Thank you

    


  • NVIDIA codec compression time

    1er avril 2019, par rmt94

    I’m working with the NVIDIA video codec to encode a YUV video to the HEVC format. The problem is that I want to know the time it takes to perform the encoding and I can not find the way.

    Other codecs supported by FFMPEG such as x265 or hevc_qsv show the encoding time at the end of the process, but in the case of the NVIDIA codec no. Does anyone know of any command or method that allows to show this information ?
