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 (...) -
De l’upload à la vidéo finale [version standalone]
31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source
Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

Shotdetect : compiling error ("undefined reference")
8 juillet 2015, par VoprosnikI am using Cygwin and I trying to install the program Shotdetect. I downloaded the source with git and also downloaded, compiled and installed ffmpeg through git.
Installation of shotdetect doesn’t follow the ./configure && make && make install routine, but a cmake system of which I have no experience. Nonetheless there is a script that automates compiling and installation.
Near the final stages of the compiling, I get a long series of errors concerning some ffmpeg modules :

Makefile:117: recipe for target 'all' failed
make: *** [all] Error 2Searching online for similar errors, I found the following proposed solutions
1) fix pkg-config setup so configure will find out all dependencies ;
2) build ffmpeg (libavcodec) without external dependencies ;
3) add external dependencies manually with configure —extra-ldflags
I guess the problem lies on how i compiled ffmpeg (just configure with no options) but other than that have no idea what to do with either of the above suggestions. Should I recompile ffmpeg with different options ?

Error of "Built target opencv_imgproc" while compiling opencv2
23 mars 2017, par HongFollowing https://github.com/menpo/conda-opencv3, while I compile opencv, there is following error (please read the error at the end of the post). The only change I made is to enable ffmpeg by modifying "-DWITH_FFMPEG=1" in BUILD.SH. Any suggestion ?

ffmpeg error "Could not allocate picture : Invalid argument Found Video Stream Found Audio Stream"
26 octobre 2020, par DinkanI am trying to write a C program to stream AV by copying both AV codecs with
rtp_mpegtsusing RTP over network

ffmpeg -re -i Sample_AV_15min.ts -acodec copy -vcodec copy -f rtp_mpegts rtp://192.168.1.1:5004


using muxing.c as example which used ffmpeg libraries.
ffmpeg application works fine.
