    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • When creating a Xing or Info tag in an MP3, may I use any MP3 header or does it have to match other frames ?

    13 décembre 2019, par Alexis Wilke

    I have a set of bare MP3 files. Bare as in I removed all tags (no ID3, no Xing, no Info) from those files.

    Just before sending one of these files to the client, I want to add an Info tag. All of my files are CBR so we will use an Info tag (no Xing).

    Right now I get the first 4 bytes of the existing MP3 to get the Version (MPEG-1, Layer III), Bitrate, Frequency, Stereo Mode, etc. and thus determine the size of one frame. I create the tag that way, reusing these 4 bytes for the Info tag and determining the size of the frame.

    For those wondering, these 4 bytes may look like this :

    FF FB 78 04

    To me it felt like you are expected to use the exact same first 4 bytes in the Info tag as found in the other audio frames of the MP3, but when using ffmpeg, they stick an Info tag with a hard coded header (wrong bitrate, wrong frequency, etc.)

    My question is : Is ffmpeg really doing it right ? (LAME doesn’t do that) Could I do the same, skipping the load of the first 4 bytes and still have the greater majority of the players out there play my files as expected ?

    Note : since I read these 4 bytes over the network, it would definitely save a lot of time and some bandwidth to not have to load these 4 bytes on a HEAD request. Resources I could use for the GET requests instead...

  • where is ffmpeg wasm output directory and how to access the files ?

    15 juin 2021, par Fabiotk

    I have the following code where I convert a video file into HLS stream format. I'm doing this in browser javascript so I don't load a lot of processing into the server. Now, the code seems to be working fine according to the logs however I can't see the output. The code is :

    


    <code class="echappe-js">&lt;script&gt;&amp;#xA;   const { createFFmpeg, fetchFile } = FFmpeg;&amp;#xA;   const ffmpeg = createFFmpeg({&amp;#xA;       corePath: &amp;#x27;https://unpkg.com/@ffmpeg/core@0.10.0/dist/ffmpeg-core.js&amp;#x27;,&amp;#xA;       log: true,&amp;#xA;   });&amp;#xA;   &amp;#xA;   ffmpeg.setLogger(({ type, message }) =&gt; {&amp;#xA;       console.log(type, message);  &amp;#xA;   });&amp;#xA;&amp;#xA;   const transcode = async ({ target: { files } }) =&gt; {&amp;#xA;       console.log(&amp;#x27;Running ffmpeg&amp;#x27;)&amp;#xA;       const { name } = files[0];&amp;#xA;       await ffmpeg.load();&amp;#xA;       ffmpeg.FS(&amp;#x27;writeFile&amp;#x27;, name, await fetchFile(files[0]));&amp;#xA;       await ffmpeg.run(&amp;#x27;-i&amp;#x27;, name, &amp;#x27;-hls_time&amp;#x27;, &amp;#x27;10&amp;#x27;, &amp;#x27;-hls_playlist_type&amp;#x27;, &amp;#x27;vod&amp;#x27;, &amp;#x27;-hls_segment_filename&amp;#x27;, &amp;#x27;part_%03d.ts&amp;#x27;, &amp;#x27;master.m3u8&amp;#x27;);&amp;#xA;&amp;#xA;   }&amp;#xA;   document.getElementById(&amp;#x27;uploader&amp;#x27;).addEventListener(&amp;#x27;change&amp;#x27;, transcode);&amp;#xA;&lt;/code&gt;&lt;/pre&gt;&amp;#xA;   &amp;#xA;&lt;p&gt;My question is, where are the &lt;code&gt;part_%03d.ts&lt;/code&gt; files (part_001.ts, etc)? I want to loop through every one of them and pass their content to another function. How to do this?&lt;/p&gt;&amp;#xA;

    I've tried a bunch of stuff including upgrading Python, upgrading brew, downloading ffmpeg etc. but cannot figure this out.
