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) (...)

Duplicate outputs using JavaCV
17 octobre 2015, par bicksterI want to use JavaCV to both live stream a video over RTMP and save it to a local file on Android. I can do both independently, but it is very inefficient. This link on ffmpeg suggests that it is possible to do it at the same time to avoid the encoding of the video twice. https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs
How do I enable this functionality in JavaCV ?

What's the difference with crf and qp in ffmpeg ?
18 novembre 2016, par NovaAfter browsing around Google, I’ve came across this page about h264 encoding and discovered about qp. https://trac.ffmpeg.org/wiki/Encode/H.264
My questions are : What are the differences with crf and qp ? Is it better to use qp over crf overall, or is it only if for using qp 0 for best lossless ? Does qp have a known sensible setting if it’s preferred ? So far, I know crf has the default value of 23 while 18 is a sensible preferred increase in quality, although I don’t understand why 18 wouldn’t be default if better sensible lossless. Lastly, would changing either of them cause incompatibility with non-ffmpeg players or just qp ?
I’m converting from webm to mp4 by the way.
I was going to test crf 23 and 18 and pick which is best but I can’t seem to find any concrete information on this comparison or about qp.

Lego Mindstorms RSO Format
14 juillet 2010, par Multimedia Mike — GeneralI recently read a magazine article about Lego Mindstorms. Naturally, the item that caught my eye was the mention of a bit of Lego software that converts various audio file formats to a custom format called RSO that can be downloaded into a Mindstorms project to make the creation output audio. To read different sources, one might be left with the impression that there is something super-duper top secret proprietary about the format. Such impressions do not hold up under casual analysis of a sample file.
A Google search for "filetype:rso" yielded a few pre-made sample that I have mirrored into the samples archive. The format appears to be an 8-byte header followed by unsigned, 8-bit PCM. More on the wiki. If FFmpeg could gain an RSO file muxer, that would presumably be a heroic feat to the Lego hacking community.
