  • AFTER PHP-FFMpeg not converting (error with ffmpeg)

    15 juin 2018, par Magurean Dan Sergiu

    I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

    Use -h to get full help or, even better, run 'man ffmpeg'

    But when I try to convert a video file with a php script it throws me a very long error.
    PHP Code :

    <?PHP
    include($_SERVER['DOCUMENT_ROOT']."/vendors/install/vendor/autoload.php");
    $ffmpeg = FFMpeg\FFMpeg::create();
    $video = $ffmpeg->open($_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.wmv');
    $video
          ->filters()
          ->synchronize();
    $format = new FFMpeg\Format\Video\X264();
    $format->on('progress', function ($video, $format, $percentage) {
       echo "$percentage % transcoded";});
    $video
         ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
    ?>

    Error displayed :

    Then I have took the basic code displayed upwards and ran it directly through ssh.

    My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

    After a few modifications

    I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.

    13 mars, par Zac Chan

    I am a novice at ffmpeg and have recently taken over a code base built by a previous engineer. The FFmpeg code is on an app engine that will edit the videos when they are uploaded.

    &#xA;

    This code generated a title animation that will later be used as an overlay.

    &#xA;

    exports.generateTitleAnimation = function(metadata, destPath, options = {}) {&#xA;const peeqLogoPath = "/app/assets/peeq-logo.png";&#xA;const whiteBarMovPath = "/app/assets/whiteBar.mov";&#xA;const titleFontPath = "/app/assets/Sofia-Pro-Black.otf";&#xA;const dateStrFontPath = "/app/assets/Sofia-Pro-Medium.otf";&#xA;const outputDuration = 5.52;&#xA;const src01 = "color=c=white:s=1920x1080:duration=" &#x2B; outputDuration;&#xA;const src02 = "color=c=white@0.0:s=1920x1080:r=120:duration=" &#x2B; outputDuration;&#xA;&#xA;var dateStrXOffset = "(92";&#xA;var filterComplexStr = "[1]";&#xA;&#xA;if (metadata.title) {&#xA;    const title = metadata.title.toUpperCase();&#xA;    filterComplexStr &#x2B;= "drawtext=fontfile=" &#x2B; titleFontPath &#x2B; ":text=&#x27;" &#x2B; title &#x2B; "&#x27;:x=&#x27;floor(92*(min((t-1.75)^29,0)&#x2B;max((t-3.75)^29,0)&#x2B;1))&#x27;:y=622&#x2B;30&#x2B;2:fontsize=70:fontcolor=black:ft_load_flags=render,";&#xA;}&#xA;if (metadata.subTitle) {&#xA;    const subTitle = metadata.subTitle.toUpperCase();&#xA;    filterComplexStr &#x2B;= "drawtext=fontfile=" &#x2B; titleFontPath &#x2B; ":text=&#x27;" &#x2B; subTitle &#x2B; "&#x27;:x=&#x27;floor(92*(min((t-2.0)^29,0.0)&#x2B;max((t-3.8)^29,0.0)&#x2B;1.0))&#x27;:y=622&#x2B;184-20-60&#x2B;9:fontsize=46:fontcolor=black:ft_load_flags=render,";&#xA;&#xA;    dateStrXOffset &#x2B;= "&#x2B;30*" &#x2B; (subTitle.length &#x2B; 1);&#xA;}&#xA;if (metadata.dateStr) {&#xA;    filterComplexStr &#x2B;= "drawtext=fontfile=" &#x2B; dateStrFontPath &#x2B; ":text=&#x27;" &#x2B; metadata.dateStr &#x2B; "&#x27;:x=&#x27;floor(" &#x2B; dateStrXOffset &#x2B; ")*(min((t-2.0)^29,0.0)&#x2B;max((t-3.8)^29,0.0)&#x2B;1.0))&#x27;:y=622&#x2B;184-20-60&#x2B;9:fontsize=46:fontcolor=black:ft_load_flags=render,";&#xA;}&#xA;console.log("generateTitleAnimation generating")&#xA;filterComplexStr &#x2B;= "split=10[t01][t02][t03][t04][t05][t06][t07][t08][t09][t10];[t02]setpts=PTS&#x2B;0.0166/TB[d02];[t03]setpts=PTS&#x2B;0.033/TB[d03];[t04]setpts=PTS&#x2B;0.05/TB[d04];[t05]setpts=PTS&#x2B;0.0666/TB[d05];[t06]setpts=PTS&#x2B;0.083/TB[d06];[t07]setpts=PTS&#x2B;0.1/TB[d07];[t08]setpts=PTS&#x2B;0.1166/TB[d08];[t09]setpts=PTS&#x2B;0.133/TB[d09];[t10]setpts=PTS&#x2B;0.15/TB[d10];[d10][d09]blend=average,[d08]blend=darken,[d07]blend=average,[d06]blend=darken,[d05]blend=average,[d04]blend=darken,[d03]blend= average,[d02]blend=darken,[t01]blend=average,colorkey=white:0.2:0.0,perspective=y1=W*0.176327:y3=H&#x2B;W*0.176327[text01];[2][3]overlay=x=(W-w)*0.5:y=(H-h)*0.5:enable=&#x27;between(t,0,3.0)&#x27;[logo01];[logo01][text01]overlay[outv]";&#xA;&#xA;var args = ["-y", "-f", "lavfi", "-i", src01, "-f", "lavfi", "-i", src02, "-i", whiteBarMovPath, "-i", peeqLogoPath, "-filter_complex", filterComplexStr, "-vcodec", "qtrle", "-crf:v", "28", "-codec:a", "aac", "-ac", "2", "-ar", "44100", "-ab", "128k", "-map", "[outv]", destPath];&#xA;&#xA;//console.log("args", args);&#xA;return childProcess.spawn(&#x27;ffmpeg&#x27;, args).then((ffResult) => {&#xA;    return destPath;&#xA;}, (err) => {&#xA;    //console.error(new Error("generateTitleAnimation:" &#x2B; err));&#xA;    console.error(err);&#xA;    return Promise.reject(err);&#xA;});};&#xA;

    However, this error only occurs on the app engine. Running nom test on my Mac generates the title perfectly.

  • x264 library speed - Altivec vs SSE2 -

    25 février 2013, par Omer Merdan

    I have simple cheap dualcore intel-3ghz-debian and access to super-expensive powerPc7-Aix.

    And after few days of strugle, i compiled libx264 and tested it on both computers :

    1. GCC : library x264 on intel (with SSE2 capabilities) and
    2. GCC on 16 core powerPc (with altivec).

    ... and result is that cheap intel is x2 times faster ! (with altivec disabled, intel is 10x times faster)

    My question : is this normal ?
    Does all other powerPC-users have same results ? Can powerPc-altivec-optimisation of x264 library work at same speed with intel... or MMX/SSE optimisation is officially at least 2 times faster for this library ?

    I am not interested in multi-thread options. Number of cores and threads are irrelevant. Just simple one-thread x264 encoding with default "medium preset" using rawvideo as source, sse vs altivec.

    Maybe native Aix XLC compiler provide better results ? (i managed only gcc to work)

    ... mac-powerpc-users maybe know something about this.
