    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) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • How to set profile compatibility and level indication of an fMP4 using ffmpeg ?

    27 novembre 2014, par Pablo Montilla

    I’m using ffmpeg to generate a fragmented mp4 stream that will be consumed by an HTML5 player using MSE. I think I have a correctly formatted mp4 stream of data with an empty moov at the start and a series of moof+mdat for the video fragments. What I’m stuck is with the codec that’s being received by Chrome.

    chrome ://media-internals has this to say :

    00:00:00 00 pipeline_state  kCreated
    
00:00:00 00 EVENT           PIPELINE_CREATED
    
00:00:00 00 EVENT           WEBMEDIAPLAYER_CREATED
    
00:00:00 00 url             blob:http%3A//localhost/3388b7f1-5567-4d76-a585-0b247affd16a
    
00:00:00 00 pipeline_state  kInitDemuxer
    
00:00:07 68 error           Video codec: avc1.4d401e

    From which I gather the problem is with the encoded data, which should be in avc1.4d0020 as its specified in the javascript.

    I’ve seen the answer to html5 video tag codecs attribute, which tells me I need to reset profile_compatibility and AVCLevelIndication, but I couldn’t find an option to do that.

    Here’s the command line I’m using (the pipe is read and sent to the web page using web sockets) :

    ffmpeg -re -i Input.mp4 -map 0:0 -y -c:v libx264 -preset veryslow -x264opts intra-refresh=1 -tune psnr -refs 1 -b:v 1500k -bf 0 -g 8 -b-pyramid none -f mp4 -movflags empty_moov+omit_tfhd_offset+frag_keyframe -frag_duration 1000000 -profile:v main -iods_video_profile 0 -flags +loop \\.\pipe\FeedPipe

    So the question is, can I set the profile_compatiblity and AVCLevelIndictation in the ffmpeg command line ?

    I'd like to extract data from codec string&#xA;For example, there is a string like "avc1.64001F"&#xA;And it produce data like below.

    &#xA;

    Codec : H264 / profile : High / Level : L3.1

    &#xA;

    I use C language and use ffmpeg library.&#xA;I keep searching how to use ffmpeg library, but I cannot find proper function to solve it.
