Configuration spécifique d’Apache
4 février 2011, parModules 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.

HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...) -

avutil/common : add av_rint64_clip
1er novembre 2015, par Ganesh Ajjanagaddeavutil/common : add av_rint64_clip
The rationale for this function is reflected in the documentation for
it, and is copied here :Clip a double value into the long long amin-amax range.
This function is needed because conversion of floating point to integers when
it does not fit in the integer’s representation does not necessarily saturate
correctly (usually converted to a cvttsd2si on x86) which saturates numbers
> INT64_MAX to INT64_MIN. The standard marks such conversions as undefined
behavior, allowing this sort of mathematically bogus conversions. This provides
a safe alternative that is slower obviously but assures safety and better
mathematical behavior.
API :
@param a value to clip
@param amin minimum value of the clip range
@param amax maximum value of the clip range
@return clipped valueNote that a priori if one can guarantee from the calling side that the
double is in range, it is safe to simply do an explicit/implicit cast,
and that will be far faster. However, otherwise this function should be
used.avutil minor version is bumped.

Best way to record a HTML Canvas/WebGL animation server-side into a video ?
14 décembre 2016, par AbhinavI have a set of animations which I can make in Canvas (fabric.js) or WebGL (three.js). I need to record them automatically, server-side, through a script and output a video file.
The animations include :
- Pictures
- Videos (with audio)
- Other animations/effects
I have researched a lot during last few months on this.
Results
1. User PhantomJS + FFMPEG
Run HTML Canvas animations on headless browser(PhantomJS) and record with FFMPEG. Here the issue is PhantomJS supports neither WebGL nor Video element. http://phantomjs.org/supported-web-standards.html2. Use Websockets to send data back to server using DataURL
Here again, we will need to run the animations on browser (which we can’t because we have to do everything on server).3. Use node-canvas
This is a library by TJ Holowaychuk which allows rendering HTML Canvas on Node.js. But it has its own limitations plus I haven’t really explored this field much.
(If someone could shed more light on this library)If anyone has done it before or can guide me somewhere useful.
All we need to do is use some data to create animations and record it into a video, everything on server side. - Pictures
