La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

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 (...)

Diamond Rio Artifacts
30 août 2012, par Multimedia Mike — Multimedia HistoryRemember the Diamond Rio PMP300 ? It’s credited with being the very first portable MP3 player, released all the way back in 1998 (I say ‘credited’ because I visited an audio museum once which exhibited a Toshiba MP3 player from 1997). I recently rescued a pristine set of Rio artifacts from a recycle pile.
I wondered if I should scan the manual for posterity. However, a Google search indicates that a proper PDF (loaded with pleas to not illegally copy music) isn’t very difficult to come by. Here are the other items that came with the unit :
Click for larger image
Ah, more memories (of dialup internet) : A tie-in with another Diamond product, this time a modem which claims to enable the user to download songs at up to 112 kilobits per second. I wonder if that was really possible. I remember that 56k modems were a stretch and 33.6k was the best that most users could hope for.
There is also a separate piece of paper that advises the buyer that the parallel port adapter might look a bit different than what is seen in the printed copy. Imagine the age of downloading to your MP3 player via parallel port while pulling down new songs via dialup internet.
The artifacts also included not one, but two CD-ROMs :
Click for larger image
One is a driver and software disc, so no big surprise there. The other has a selection of MP3 files for your shiny new MP3 player. I’m wondering if these should be proactively preserved. I was going to process the files’ metadata and publish it here, for the benefit of search engines. However, while metadata is present, the files don’t conform to any metadata format that FFmpeg/Libav recognize. The files mention Brava Software Inc. in their metadata sections. Still, individual filenames at the end of this post.
Leftovers :
A few other miscellaneous multimedia acquisitions :
I still want to study all of these old multimedia creation programs in depth some day. Theatrix Hollywood is a creative writing game, Wikipedia alleges (I’m a bit rigid with my exact definition of what constitutes a game). Here is an example movie output from this software. Meanwhile, the Mad Dog Multimedia CD-ROM apparently came packaged with a 56X CD-ROM drive (roughly the pinnacle of CD-ROM speeds). I found it has some version of Sonic Foundry’s ACID software, thus making good on the “applications” claim on the CD-ROM copy.

playing MPEG-dash streaming with FFMPEG
24 mars 2016, par Thanh NguyenI’m having a problem when playing MPEG-dash streaming with ffmpeg. I know there are a lot of tools can play MPEG-dash like OSMO4, DASH.js.. However, I am wondering if I can play MPEG-dash with FFMPEG ?
And one more question, How can I determine startup time when playing MPEG-dash streaming ? It means, the duration time when I request a MPD file from a server until I get the first picture of video display on a screen ?
Thanks ! -
How do I use native C libraries in Android Studio
11 mars 2015, par NicholasI created a problem some years back based on https://ikaruga2.wordpress.com/2011/06/15/video-live-wallpaper-part-1/. My project was built in the version of Eclipse provided directly by Google at the time and worked fine with a copy of the compiled ffmpeg libraries created with my app name.
Now I’m trying to create a new app based on my old app. As Google no longer supports Eclipse I downloaded Android Studio and imported my project. With a few tweaks, I was able to successfully compile the old version of the project. So I modified the name, copied a new set of ".so" files into app\src\main\jniLibs\armeabi (where I assumed they should go) and tried running the application on my phone again with absolutely no other changes.
The NDK throws no errors. Gradle compiles the file without errors and installs it on my phone. The app appears in my live wallpapers list and I can click it to bring up the preview. But instead of a video appearing I receive and error and logCat reports :

</clinit>I’m a novice Android/Java/C++ developer and am not sure what this error means, but Google leads me to believe that my new libraries are not being found. In my Eclipse project I had this set of libraries in "libs\armeabi", and another copy of them in a more complicated folder structure at "jni\ffmpeg-android\build\ffmpeg\armeabi\lib". Android Studio appears to have kept everything the same, other than renaming "libs" to "jniLibs", but I’m hitting a brick wall with this error and am unsure how to proceed.
How can I compile this new app with the new name using Android Studio ?
