  • FFmpeg streaming using H.264 (with audio) - Red5 media server (Ubuntu OS)

    6 février 2013, par B.B10

    I'm trying to stream my webcam with FFmpeg to my Red5 server using RTMP. I've done this successfully using FLV format with the following line :

    ffmpeg -f video4linux2 -i /dev/video0 -f flv rtmp://localhost/live/livestream

    I'm new to FFmpeg and live streaming, and I've tried to stream using H.264/MPEG-4. But my knowledge is a bit limited with the FFmpeg options (which I did find here : http://man.cx/ffmpeg%281%29).

    So, my questions would be :

    1. How can I use H.264/MPEG-4 to stream to my Red5 server ?

    2. What are the options to stream audio as well ?

    3. And one final issue is :

    I'm having a delay of about 5 seconds when I play the content with JWPlayer in Mozilla Firefox (on Ubuntu). Can you please help me out to solve this problem ? Any suggestions why this might be ?

    Many thanks
