  • 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.

  • 'Range' request header in ffmpeg

    12 février 2017, par cole

    Recently I am working on parsing some videos’s address from a web site.After parsing,I use IjkPlayer based on ffmpeg to play it.However I get 403 code,with Chi-Hsuan Yen’s (A author of youtube-dl) help,I know ‘range’ header result in the 403 response code.

    A Solution

    set Range :space

    However

    If I set Range :space,I can’t seek this video when I play it on Android Phone.So do you have another solution for 403 code ?

  • Use FFmpeg to rotate the video based on its metadata ? Why does Android put the wrong metadata ?

    22 juillet 2015, par Mauro Valvano

    I have a website where the user uploads a video.
    For my website i have also an Android application.
    The website creates a thumbnail of each uploaded video (from browser or Android).

    The problem is that for normal videos it’s all OK, but for android my videos are rotated by 90°.

    I think that Android has a bug, because when I see with FFmpeg the video’s metadata, for a normal recorded video I got a rotate=90 value, and for a 90° rotated video, I don’t have anything in the metadata (and the thumbnail is correct).

    Why ?

    This is an image of a normal recorded video (with the phone in portrait mode).

    FFmpeg showing the rotate metadata in a normal recorded video

    Anyway, I have the metadata in the video, can I create its thumbnail based on its metadata’s rotate value without extracting the metadata and then use ffmpeg to rotate the video on this value ?

    Thank you in advance.

  • FFMPEG video encoded by android app doesn't scale properly on the website

    9 octobre 2016, par Ahmed Mujtaba

    I’m trying to creat e an app that records a video on phone and uploads it to the website. I’m using a FFMPEG library to encode the video to be streamed on the web. The command I’m using for encoding is below :

    -y i inputPath -vf scale=640:480,transpose=1 -strict experimental -s 360x640 -r 25 -vcodec mpeg4 -b 1000k ab 48000 -ac 2 -ar 22050 destinationPath

    The video is encoded fine but when I try to play it on the website, it’s stretched vertically and goes off the screen. I’m using html5 player to play it on the web. Here’s what the video looks like

    enter image description here

    The video uploaded from the website is encoded using libx264 codec and it plays fine. However the library I’m using to encode on the android app doesn’t support libx264. I’m not sure if it’s the incorrect aspect ratio that’s messing up the playback or something else. I’ve set the aspet ratio to 640:480 but that hasn’t fixed things.
    Can anyone help ?
