  • Stream a short video continuously with ffmpeg

    12 janvier 2014, par Blue Sky

    I have a short video (3 sec), and I want to stream it over a UDP address like udp ://127.0.0.1:1000 continously (repeatedly) so that the stream runs forever unless the user stops the streaming session. How can I do so ? Thanks !

  • I am able to create m3u8 file using ffmpeg from rtmp live but not able to play the file in html5 video tag & apple device

    3 janvier 2014, par Nikita

    I am able to create the m3u8 file by following steps :

    1.Execute ffmpeg -v verbose -i rtmp://<host>:<port>/<stream> -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 <pathtofolderyouwantto>/<streamname>.m3u8
    
</streamname></pathtofolderyouwantto></stream></port></host>

    2.Make that folder you just mentioned on ffmpeg command () to be accessible by an http url.

    3.Create a simple html page to play :

    <video controls="controls" width="480" height="270" src="<streamName>.m3u8"></video>

    But not able to play using html5 video tag as well as in apple device.

    following is my ffmpeg console output :
