  • FFmpeg copying from udp to rtsp

    28 décembre 2014, par ladi2000

    So I have a (live)video stream on udp ://10.5.5.100:8463 and I copy it to udp ://localhost:1000.

    ffmpeg -f mpegts -i "udp://10.5.5.100:8554?fifo_size=10000" -f mpegts -vcodec copy udp://localhost:1000/go

    And it works fine in VLC but Wirecast doesn’t accept udp ://..., but it accepts rtsp ://...

    but I don’t now much about ffmpeg, so I only changed udp to rtsp

    ffmpeg -f mpegts -i "udp://10.5.5.100:8554?fifo_size=10000" -f mpegts -vcodec copy rtsp://localhost:1000/go

    But it doesn’t work and outputs this

    rtsp://localhost:1000/go: Protocol not found

    Thank you for answers !!

  • ffmpeg : How to get list of available codecs with PHP ?

    9 août 2013, par IIIOXIII

    Problem is, I am trying to convert (through php), a .3gp (or any video format) file to ogg.

    When I do not specify -vcodec and -acodec, the video is converted, but does not have any audio.

    I had read here and other places that I need to specify -acodec libvorbis, however, when I specify the codec as libvorbis, the conversion fails : video converts to 0byte file.

    Basically, I am trying to determine if the codec specified is actually part of the ffmpeg build I am using as a process of narrowing down my issue.

    Code that produces full length video without sound :

    $srcFile = 'anyvideo.3gp';
    
$destFile = 'anyvideo.ogg';
    
$ffmpegPath = 'path/to/ffmpeg.exe';
    
$ffmpegObj = new ffmpeg_movie($srcFile);
    
$srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth()); 
    
$srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
    
$srcFPS = $ffmpegObj->getFrameRate(); 
    
$srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
    
$srcAR = $ffmpegObj->getAudioSampleRate();
    
$srcLen = $ffmpegObj->getDuration();
    

    
exec($ffmpegPath." -i ".$srcFile." -ar ".$srcAR." -s ".$srcWidth."x".$srcHeight." ". $destFile);

    And the code that produces 0byte file :

    exec($ffmpegPath." -i ".$srcFile." -acodec libvorbis -ar ".$srcAR." -s ".$srcWidth."x".$srcHeight." ".$destFile);

    So, my question is, how do I determine the codec's available to ffmpeg using PHP ? Can it even be done ?
