Participer à sa documentation
10 avril 2011La documentation est un des travaux les plus importants et les plus contraignants lors de la réalisation d’un outil technique.
Tout apport extérieur à ce sujet est primordial : la critique de l’existant ; la participation à la rédaction d’articles orientés : utilisateur (administrateur de MediaSPIP ou simplement producteur de contenu) ; développeur ; la création de screencasts d’explication ; la traduction de la documentation dans une nouvelle langue ;
Pour ce faire, vous pouvez vous inscrire sur (...) -
Encodage et transformation en formats lisibles sur Internet
10 avril 2011MediaSPIP transforme et ré-encode les documents mis en ligne afin de les rendre lisibles sur Internet et automatiquement utilisables sans intervention du créateur de contenu.
Les vidéos sont automatiquement encodées dans les formats supportés par HTML5 : MP4, Ogv et WebM. La version "MP4" est également utilisée pour le lecteur flash de secours nécessaire aux anciens navigateurs.
Les documents audios sont également ré-encodés dans les deux formats utilisables par HTML5 :MP3 et Ogg. La version "MP3" (...)

The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority).
I found thepjsua_vid.ois very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

Here is my build log :

FFMPEG unwanted rotation
5 mars 2015, par BenWhen I add a watermark image with a landscape orientation to a video that has a portrait orientation the video automatically rotates to landscape. How do I prevent this ? Also, the audio file isn’t being merged into the output. How can I include the audio.mp3 to be the sole audio track ?

iOS Build PJSIP with FFmpeg+libx264
22 février 2021, par MeonardoI have built the FFmpeg with libx264 into static libs, here is my directory tree.

The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority).
I found thepjsua_vid.ois very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

Here is my build log :
