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 (...) -
Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

FFMpeg Coding in C : Encoder returns EOF at first interaction. Encoder not opened correctly ? [closed]

The program should decode a video into the individual frames convert them to RGB24, so I can work with the raw data of the frame, then convert it back to the original format and encode the frames.


The encoder doesn't play nice, as I get an EOF error at avcodec_send_frame().
But I couldn't figure it out why the encoder behaves like this.
And yes I have read the docs and example files, but either I'm massivly missing a crucial detail or I'm just ****.


Any and all help will be and is massivly appreciated.


PS. : The used libraries are libavutil, libavformat, libavcodec, libswscale. All installed with the "-dev" suffix through linux commandline. Should all be the version 7.0 libraries.


Thanks in advance.
With best regards.

- Read the docs
- Shifting the encoding step out of the decoding while loop
