  • 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 (...)

  • ffmpeg stream input sdp shows warning keyframe missing

    27 mars 2021, par Doua Beri

    I'm using ffmpeg 4.3.2.
I'm trying to forward a stream to a rtmp server having sdp file as input

    


    Opening the sdp file with VLC everything is working great. The same thing happens when I use ffplay

    


    ffplay -i rtp-forwarder.sdp -protocol_whitelist file,udp,rtp


    


    The problem starts when I start streaming to a rtmp server. The audio is good but the video is just a black screen. I event tried to stream to youtube rtmp server but it didn't work.

    


    I'm new to ffmpeg. Let me know if I'm missing something.

    


    I'm using this command

    


    ffmpeg -protocol_whitelist file,crypto,udp,rtp -re -i rtp-forwarder.sdp -c:v libx264 -b:v 3000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://localhost/live/test


    


    The sdp file content is like this

    


    v=0
o=- 0 0 IN IP4 192.168.1.49
s=Pion WebRTC
c=IN IP4 192.168.1.49

  • ffmpeg conversion x264 [error] : malloc of size 769152 failed

    18 décembre 2014, par prashanthp

    I am trying to convert video recorded from Android smart watch (.mp4 format) to a format (.mp4) which playable on all browsers. The video recorded from smart watch is not playing in the browsers. so, i’ve used ffmpeg to convert in into a playable mp4 format.

    But sometimes it is showing error as x264 [error]: malloc of size 503008 failed

    What is the reason for this. Sometimes it’s getting converted and sometimes it is showing error .

    Here is the console output.

    When i execute this from shell it is working fine. But when i create a script file and trying to execute that script file from php , it is showing error’s. I increased the memory limit in php, still it is showing error. Also , we are using ZEND framework. Is there any problems with ZEND ??
