  • Not able to configure FFserver for RTSP

    2 novembre 2015, par Sujith

    I am kind of new to the streaming world... so, please forgive me if I ask kind of dumb question.

    I am trying to stream my pre-recorded file over RTSP through FFserver.

    My config file is :

    RTSPPort 8544
    
<feed>
    
    File /home/xyz/tmp/feed2.ffm
    
    FileMaxSize 200K
    
    ACL allow 127.0.0.1
    
</feed>
    

    
<stream>
    
    Feed feed2.ffm
    
    Format rtsp
    
    VideoFrameRate 15
    
    VideoSize 352x240
    
    VideoBitRate 256
    
    VideoBufferSize 40
    
    VideoGopSize 30
    
    AudioBitRate 64
    
    StartSendOnKey
    
</stream>

    After starting the server, it give the below log :

    $ ./ffserver -f doc/ffserver.conf

Wed Sep 19 17:03:32 2012 FFserver started.

    And now from my VLC client I am trying to type the URL : rtsp ://xxx.xxx.xxx.xxx:8554/test.sdp

    But, what happens is that, there is no response on the ffserver.

    I have no clue what might be the problem. Thanks in advance.

  • ffmpeg terminates without any output

    11 septembre 2012, par Khan

    I am using ffmpeg to convert a video file to mp4. here is my code

        echo "converting ".basename($src)." --- to --- ".basename($dest).".mp4...<br />";
    
$command = FFMPEG.&#39; -i &#39; . $src . &#39; -sameq -strict -2 -vcodec libx264 -ar 22050 -y &#39; . $dest.&#39;.mp4 2>&amp;1&#39;;   //
    
echo $command.&#39;<br />&#39;;
    

    
exec($command,$output,$status);
    
echo &#39;<pre>&#39;,join(&#39;<br />&#39;,$output),&#39;</pre><br />&#39;;
    

    
if($status == 0) {              // Success
    
    echo &#39;Successfully converted to MP4!<br />&#39;;
    
} else {
    
    echo $status."<br />failed<br />";
    
}

    The code works fine on my localhost (Windows 7 + wamp).. But on live server , only $command is echoed.. and script is terminated. The output file is generated but it is only 4.5MB (it should be around 17 MB) and not complete... and sometime I get the following output..

  • Error while tanscoding using ffmpeg

    31 octobre 2012, par Sujith

    I have made some changes in the ffserver code and have started the HTTP server.

    Now, when I am trying to run the command to stream the media, it is giving some error.

    The command is :

    ffmpeg -i test.mp4 http://xxx.xxx.xxx.xxx:8090/feed1.ffm

    The error is :
