  • Animated Gif using PHP 5 and ffmpeg [closed]

    1er décembre 2012, par user1828200

    I make an Animated Gif, by download a video from youtube with youtube-dl and then convert it into AVI with ffmpegand then make animated gif through convert. It works, but speed is very slow.

    Here is my code

    Youtube Download :

    shell_exec("youtube-dl -o JNJNoaIU7qs.flv --format=5 --audio-quality=9 http://www.youtube.com/watch?v=JNJNoaIU7qs);

    Convert to AVI , because I want to make Small Gif so time manipulation is not done with youtube-dl thats why i convert avi with time manipulation

    shell_exec("ffmpeg -i JNJNoaIU7qs.flv -sameq -ss 00:00:5 -t 00:00:10 JNJNoaIU7qs.avi");

    Make Gif

    shell_exec("convert -quiet -delay 0  JNJNoaIU7qs.avi JNJNoaIU7qs.gif");

    It creates the GIF files, but it is very slow, how can I increase the speed of conversion ?

  • How to make mp4 rendering visible on Mac ?

    24 octobre 2022, par János

    Generating mp4 from gif like this :

    


        await new Promise<void>((resolve, reject) => {&#xA;        ffmpeg&#xA;            .input(`/tmp/input_${name}.gif`)&#xA;            .outputOptions([&#xA;                &#x27;-c:v libx264&#x27;,&#xA;                &#x27;-movflags &#x2B;faststart&#x27;,&#xA;                &#x27;-movflags frag_keyframe&#x2B;empty_moov&#x27;,&#xA;            ])&#xA;            .noAudio()&#xA;            .output(`/tmp/output_${name}.mp4`)&#xA;            .on(&#x27;end&#x27;, () => {&#xA;                console.log(&#x27;MP4 video generated&#x27;)&#xA;                resolve()&#xA;            })&#xA;            .on(&#x27;error&#x27;, (e) => {&#xA;                console.log(e)&#xA;                reject()&#xA;            })&#xA;            .run()&#xA;    })&#xA;</void>

    &#xA;

    will generate mp4, but can be watch only in Chrome, not in Safari or Quicktime Player.

    &#xA;

    We tried many other option like this :

    &#xA;

    &#x27;-pix_fmt yuv420p&#x27;,&#xA;&#x27;-vf "scale=trunc(iw/2)*2:trunc(ih/2)*2"&#x27;,&#xA;

    &#xA;

    but it raise an error :

    &#xA;

    Error reinitializing filters!&#xA;Failed to inject frame into filter network: Invalid argument&#xA;

    &#xA;

  • ffmpeg Invalid data found when processing input

    20 mai 2019, par Sulli

    I’m trying to download a specific part of a youtube video with this code :

    step=`youtube-dl -g -f 'bestvideo[ext=mp4]' https://www.youtube.com/watch?v=pMntMsHTDZ0`
    
ffmpeg -nostdin  -i "$step" -ss 00:00:10.00 -t 00:00:02.00 -c copy frames/out.mp4

    but I’m getting this error :

    I don’t understand this error, and this code has worked for tens of videos I’ve downloaded before.

    How to fix this or get more information on the error ?
