  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • error : av_interleaved_write_frame() : Unknown error

    12 avril 2014, par John Qualis

    I am new to ffmpeg. I am trying to stream my webcam using ffmpeg (x264 encoding) on a windows machine to ffserver on a linux server and restream it. I am getting the following error : av_interleaved_write_frame() : Unknown error
    I checked about it on the net and came across mails which said it could be related to version mismatch between ffmpeg and ffserver. I made sure that all libraries that are used by ffmpeg and ffserver have the same version. I am still getting this error. Appreciate any help in solving this issue.

    I am using the following command :

     .\ffmpeg.exe -f dshow -i video="Webcam C170":audio="Microphone (3- Webcam C170)" -an -g 94 -vcodec libx264 -b:v 512k -r 30 -f flv http://AA.BB.CC.DD:8090/feed1.ffm

    I get the followoing errors -
