  • 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 can I reencode a video to match another's codec exactly ?

    24 janvier 2020, par Stephen Schrauger

    When I’m on vacation, I usually use our camcorder to record videos. Since they’re all the same format, I can use ffmpeg to concat them into one large, smooth video without re-encoding.

    However, sometimes I will use a phone or other camera to record a video (if the camcorder ran out of space/battery or was left at a hotel).

    I’d like to determine the codec, framerate, etc used by my camcorder and use those parameters to convert the phone vidoes into the same format. That way, I will be able to concatonate all the videos without re-encoding the camcorder videos.

    Using ffprobe, I found my camcorder has this encoding :

      Input #0, mpegts, from 'camcorderfile.MTS':

    I’m presuming that ffmpeg will automatically take any acceptable video format, and that I only need to figure out the output settings. I think I need to use -s 1920x1080 and -pix_fmt yuv420p for the output, but what other flags do I need in order to make the phone video into the same encoding as the camcorder video ?

    Can I get some pointers as to how I can translate the ffprobe output into the flags I need to give to ffmpeg ?

    Edit : Added the entire Input #0 for both media files.

  • ffmpeg options for encoding a video mpeg2video but with .mov extension

    20 septembre 2020, par Selene

    I just finished a project, and need to produce an output in the specific format, should be exactly the same as the format of the video I received.
The best way for me to identify the source format was to use ffprobe. Here was the output of that :

    I did a lot of video work on the above file, and as part of my pipeline, I converted the file to ProRes4444. Now I need to get this video into the same format as above.

    


    Couple of questions on the format, if I understand it correctly, mpeg2video is mpeg2, this would not normally appear as .mov file, but the source is as mov container. Why ?

    


    Does the encoder from the input format matter ? specifically the XDCAM ?

    


    Alternative to solving my problem would be to use media encoder, but even that application doesn't seem to give me options at mov + mpeg2, and if it is mov, it almost forces to use Apple ProRes to keep high resolution. Also, none of the options allow me to set fps at the source level, which is 54.94, and the closest option I have is 59.94.

    


    Please help,
