ffmpeg terminates without any output
11 septembre 2012, par KhanI 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.' -i ' . $src . ' -sameq -strict -2 -vcodec libx264 -ar 22050 -y ' . $dest.'.mp4 2>&1'; //
echo $command.'<br />';
exec($command,$output,$status);
echo '<pre>',join('<br />',$output),'</pre><br />';
if($status == 0) { // Success
echo 'Successfully converted to MP4!<br />';
} 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..

Not able to configure FFserver for RTSP
2 novembre 2015, par SujithI 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>

VideoFrameRate 15
VideoSize 352x240
VideoBitRate 256
VideoBufferSize 40

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.
