  • 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 (...)

  • Convert wmv to mp4 with ffmpeg failing

    10 janvier 2012, par Morph

    I've seen quite a few posts on this, but I can't piece together whether I am doing things right, wrong, or need to download more stuff. I am converting from wmv to mp4 without complaints, but then when I go to play it on the browser window (HTML5) the player just turns grey and blanks out the controls.

    Installing ffmpeg I do

    ./configure --disable-yasm ; make ; make install

    Unless I include the disable yasm it wont go any further. Then I do

    ffmpeg -i myvideo.wmv myvideo.mp4

    All good so far. In my html source I have :

     <video width="320" height="240" controls="controls">
     <source src="myvideo.mp4" type="&#39;video/mp4;" codecs="avc1.42E01E, mp4a.40.2"></source>
     Your browser does not support the video tag.
     </video>

    I am playing this in Chrome 15 and ffmpeg -v is

    ffmpeg version 0.8.6, Copyright (c) 2000-2011 the FFmpeg developers
    built on Dec  1 2011 15:42:06 with gcc 4.1.2 20080704 (Red Hat 4.1.2-51)
    configuration: --disable-yasm
    libavutil    51.  9. 1 / 51.  9. 1
    libavcodec   53.  7. 0 / 53.  7. 0
    libavformat  53.  4. 0 / 53.  4. 0
    libavdevice  53.  1. 1 / 53.  1. 1
    libavfilter   2. 23. 0 /  2. 23. 0
    libswscale    2.  0. 0 /  2.  0. 0

    So I get the HTML5, click on it to play the movie but then the control bar greys out, leaving the play button, but then the play button cannot be clicked and nothing plays.

    Is there something wrong with what I have done above ? Do I need to download some separate mp4 driver and compile it ? I see people referring to h.264 but I thoughts ffmpeg had that already included...

  • ffmpeg determine correct codec to use

    6 janvier 2015, par nha

    I am trying to use .y4m files that I feed into Chrome for playing.
    This is the only format that I can use.

    I have a set of .y4m files that are working for my use case, taken from here.
    For example let’s say that I use the file mobile_qcif_7.5fps.y4m.

    I also have a .mp4 file (specifically the sample small.mp4 file from techslides ). I know how to convert small.mp4 to small.y4m with the following command :

    ffmpeg -y -i small.mp4 small.y4m

    I would like the resulting file to be accepted by Chrome, just like the other file.
    What options should I use (and how to find them) ?

    Additional information

    ffprobe gives :

    Head of the files

    Not sure if this is relevant, but the text content of both files begin like that :

    mobile_qcif_7.5fps.y4m
    YUV4MPEG2 W176 H144 F15:2 Ip A128:117

    small.y4m (invalid)
    YUV4MPEG2 W560 H320 F15:2 Ip A0:0 C420mpeg2 XYSCSS=420MPEG2
    FRAME

    Additional experiment

    Taking the sample mobile_qcif_7.5fps.y4m, turning it into a .mp4 file and then back into a .y4m produces an invalid file (at least for Chrome).

    Answer to comments in the answer of @SirDarius

    Following the suggestion of @SirDarius ; I tried the following commands.
    They failed to produce a valid file.

    When trying other formats (like yuv420p12be, which was in the output of -pix_fmts), I had the following output (hence my previous trials) :

    Could not write header for output file #0 (incorrect codec parameters ?): Input/output error

    After that, I also tried to edit with an hexadecimal editor (bless) the small_yuv420p.y4m file. I replace C420mpeg2 by C420, and the file was accepted by Chrome.
    What does the number in 420p[number] correspond to ? It is not explained there.
    Is there any way to make ffmpeg output this kind of header files ?

    @SirDarius, thank you again for your help.

    The question

    (in case you forgot after this text blob)

    How can I convert the small.mp4 into a small.y4m file that has the same properties as the mobile_qcif_7.5fps.y4m file ?

  • ffmpeg - Adding audio to a complex filter

    9 janvier 2015, par user3630651

    I am using c# to programmatically write an ffmpeg command to crossfade a logo into a video. I also need to cut a couple of seconds into the video.

    Here is the currently working ffmpeg command :
    (No audio)

    I want to add audio from "video.mp4"([1:a]) to the output starting a few seconds in, how do I go about this without causing a buffer overflow ?

    Thank you for your help in advance !
