  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • 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) (...)

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Sample rate not set. Could not write header for output file #0 (incorrect codec parameters ?) : Invalid argument

    12 février 2021, par Pasindu Dilshan

    I am using this command to transmit RTP with FEC

    


    ffmpeg -re -i -c copy -map 0 -f rtp_mpegts -fec prompeg=l=5:d=20 rtp ://ip:5000

    


    The following error occurred.

    


    [rtp_mpegts @ 0x7757980] sample rate not set
Could not write header for output file #0 (incorrect codec parameters ?) : Invalid argument

    


    what is the reason for that ? please help me.

    


  • 'pjsip-apps/Samples' Cannot functionally run vid_streamutil.c sample

    2 décembre 2020, par ShootingKIng

    Issue Description
After building[Build Varient=Debug, Build Config=x64] the latest pjproject-vs14 (retargeted to MSVS 2017, WINSDK=8.1, because my application works at these config) as per the build instruction on trac website. Successfully built pjsua and samples.

    


    I want to use only RTP + FFMPEG APIs (pjmedia) for my application from pjproject.

    


    My config_site.h

    


    #define PJMEDIA_HAS_VIDEO           1
#define PJMEDIA_HAS_FFMPEG          1


    


    FFMPEG (pre build from ffmpeg-N-100121-g052b4c3481-win64-gpl-shared.zip)

    


    But running the example, vid_streamutil.c did not work as expected (? Whats the normal expected behaviour ?).
It says

    


    ffmpeg_vid_cod  ffmpeg err -22: Invalid argument
vstenc0000016B  Codec encode_begin() error: Codec internal creation error (PJMEDIA_CODEC_EFAILED)


    


    To Reproduce
Steps to reproduce the behavior :

    


      

    1. run vid_streamutil.exe with parameter : --codec=H264 --remote=127.0.0.1:5000 --play-file=test.avi --send-only
(test.avi file being a sample file)

      2. 


    


    Expected behavior
Get some RTP packets in wireshark while listening to ports 4000 and 5000 maybe ? I dont know whats the expected behaviour, documentation dosent say anything about this :(

    


    Logs/Screenshots
Couldn't catch anything on Wireshark.
Console log of vid_streamutil.exe is

    


    vid_streamutil.exe --codec=H264 --remote=127.0.0.1:5000 --send-only --play-file=test.avi

    FFmpeg command :

    


    String[] complexCommand = {"ffmpeg","-y" ,"-i",  "/sdcard/videokit/in.mp4","-strict","experimental",
            "-vf", "movie=/sdcard/videokit/watermark.png [watermark];" +
            " [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s",
            "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab",
            "48000", "-ac", "2", "-ar", "22050", "/sdcard/videokit/out1.mp4"};


    


    Tis command is from a sample project. How do I pass the video path to this command ? I do not know how to edit the command to support my requirement. Can someone guide me through this. Any help will be really helpful. Thank you.
