Question

私はのFLV、MP4ファイルを変換しようとしていますが、私は0サイズのFLVファイルを取得していますが、

ffmpeg: /usr/local/bin/ffmpeg file 




path: 16112007069.mp4 




srcAR: 16000 




srcAB:48 




dimention: 352 x 288 destFile: 16112007069.flv 

コーディング部分に私を助けてくださいすることができます:)

$srcFile = "/file destination/16112007069.mp4"; 
$destFile = "/file destination/16112007069.flv"; 
$ffmpegPath = "/usr/local/bin/ffmpeg"; 

$ffmpegObj = new ffmpeg_movie($srcFile); 

$srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth()); 
$srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight()); 
$srcFPS = $ffmpegObj->getFrameRate(); 
$srcAB = intval($ffmpegObj->getAudioBitRate()); 
$srcAR => $ffmpegObj->getAudioSampleRate(); 

exec($ffmpegPath . " -i " . $srcFile . " -ar " . $srcAR . " -ab " . $srcAB . " -f flv -s " . $srcWidth . "x" . $srcHeight . " " . $destFile . " 2>&1", $output); 

var_dump($output); 

print "<br />ffmpeg: $ffmpegPath<br />"; print "file path: $srcFile<br 
/>"; print "srcAR: $srcAR<br />"; print "srcAB: $srcAB<br />"; print 
"dimention: $srcWidth x $srcHeight<br />"; print "destFile: 
$destFile<br />"; 


function makeMultipleTwo ($value) { 
    $sType = gettype($value/2); 
    if($sType == "integer") 
    { 
     return $value; 
    } else { 
     return ($value-1); 
    } 
} 

注は、私が追加：

if($srcAR<41000){ $srcAR = "41000"; } 

上記とその動作！

Answer 1

テスト、これは1：

ffmpeg -i src.avi -an dest.flv 

Answer 2

この$のffmpegのを試してみてください-i src.avi dest.flvこの質問のプログラミング部分である
