  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • FFmpeg - merge videos with different rotation

    1er octobre 2019, par sir.zaquan

    I work with FFmpeg on Android. I have 2+ videos - from front-camera and main-camera. And I want to merge them into one video.

    But videos from front-camera are upside-down. Rotation of video from fr.camera - 270, from main - 90.

    How can I merge them properly ?
    Now I use this :

    val inputCommand = arrayListOf<string>()
    
    inputCommand.add("-noautorotate")
    
    inputCommand.add("-i")
    
    inputCommand.add(videoPath)
    
    inputCommand.add("-map_metadata")
    
    inputCommand.add("0")
    

    
    if (angle.equals("270", true)) {
    
        inputCommand.add("-metadata:s:v:0")
    
        inputCommand.add("rotate=180")
    
    }
    

    
    inputCommand.add("-codec")
    
    inputCommand.add("copy")
    
    inputCommand.add("-preset")
    
    inputCommand.add("ultrafast")
    
    inputCommand.add("-b:v")
    
    inputCommand.add("1500k")
    
    inputCommand.add(outputFile.path)
    
    inputCommand.add("-y")
    
</string>

    But it doesn’t work. -metadata:s:v:0 rotate=180 doesn’t do anything.
    I also tried to use -vf transpose=1,transpose=1 but it doesn’t have effect too.

    What to do ?

    ffmpeg version n4.0-39-gda39990

    Input and Output metadata doesn’t change.

  • ffmpeg : Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_pad_5

    26 mars 2019, par rsswtmr

    This shouldn’t be that hard. I’m trying to combine three disparate video sources. I’m upscaling them to a consistent 1280x720 frame, with black backgrounds for letterboxing, and trying to concatenate to the output file. The two input files are show segments, and the bumper is a random commercial that goes in the middle.

    On an iMac Pro, System 10.14.3, ffmpeg 4.1.1. The command I’m trying to make work is :

    ffmpeg -y -hide_banner -i "input1.mkv" -i "bumper.mkv" -i "input2.mkv" -filter_complex '[0:v]scale=1280x720:force_original_aspect_ratio=increase[v0],pad=1280x720:max(0\,(ow-iw)/2):max(0\,(oh-ih)/2):black[v0]; [1:v]scale=1280x720:force_original_aspect_ratio=increase[v1],pad=1280x720:max(0\,(ow-iw)/2):max(0\,(oh-ih)/2):black[v1]; [2:v]scale=1280x720:force_original_aspect_ratio=increase[v2],pad=1280x720:max(0\,(ow-iw)/2):max(0\,(oh-ih)/2):black[v2]; [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1 [outv] [outa]' -map "[outv]" -map "[outa]" 'output.mkv'

    The resulting frame I get back is :

    I have no idea what Parsed_pad_5 means. I Googled Cannot find a matching stream for unlabeled input pad and found absolutely no explanation, anywhere. I’m a relative ffmpeg newbie. Before I start rooting around in the source code, can anyone point me in the right direction ? Thanks in advance.

  • nginx : [emerg] invalid port in url "http://192.168.0.100:80/live" in nginx.conf - Restreaming OBS to LAN

    17 novembre 2018, par popek069

    I want to restream OBS to LAN. So I set up nginx server. The server receive stream from OBS using RTMP and restreams it to HTTP to view from another device.
    Streaming from OBS works, but when I start nginx I get an error

    PS C:\Users\popek\Downloads\nginx> .\nginx.exe -s reload
    
nginx: [emerg] invalid port in url "http://192.168.0.100:80/live" in C:\Users\popek\Downloads\nginx/conf/nginx.conf:187

    I’m new to nginx and I’m running Windows 10, nginx server and OBS are on the same pc with ip 192.168.0.100
    I’d like to also reencode stream using ffmpeg if it’s possible. I know ffmpeg, I don’t know only how to set input and output.
