Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

Is it possible to force I_PCM mode in x264 ?
10 octobre 2012, par cloudravenI need to use I_PCM mode in all blocks for some of I frames in video being compressed using x264. I know those frames will take a huge amount of space, but it is a requirement to keep them as faithful to the source as possible and to make them very fast to encode / decode (I_PCM should be super fast and lossless). Is there a way to force x264 to programatically do this.
I am using libx264 to do this, but I haven't found a way to specify custom macroblock type within a given frame. If it is not supported, how hard would it be to modify the library to do so and where should I look at first ? -
