• Stream frames of videos to server, compile, and download

  20 avril 2016, par Amol Patel

  I have an application that currently allows a user to upload a video and plays the gray-scaled version of the video side by side in real time. I want to be able to upload the gray-scaled video to a server frame by frame, compile the frames, and then allow the user to download the video. I have looked at various libraries such as ffserver, stream-encoder.js, node-video, etc. but have not been able to find something that does what I need. I plan on running ffmpeg on the server side to compile the frames

  Any tips or libraries I could use would be very helpful.

  Thanks

• Anomalie #3540 : menus des sous-rubrique

  29 mars 2016, par b b

  C’est la conception de la dist "qui impose ça". Comme tu le remarques, le menu n’est affiché que s’il y a bien plus d’une rubrique. Je ne pense pas que ça soit bloquant pour la dist, puisque la page d’un des articles affiche bien la liste des rubriques dans le bloc lattéral, cf :

  http://3540.grml.eu/spip.php?article2

  De plus, il y a aussi le fil d’ariane et le plan du site...

  Et je ne suis pas certain pas qu’il soit une bonne idée d’introduire un "menu déroulant" dans la dist.

• How to compile FFProbe as stand-alone application ? (Mac/Linux/Win)

  16 janvier 2016, par Hanzaplastique

  I’m trying to compile FFMPEG (I’m actually only looking for FFProbe, which is included in the FFMPEG tools) as a standalone application for MacOS X, Linux and possibly Windows.
  With standalone I mean that the libraries (x264, OpenJPEG, etc) are "embedded" into the executable so that I have to distribute only one executable for FFProbe - I apologize that I don’t know the proper lingo for this (please let me know), I’m a newbie when it comes to this.

  I have started by trying to do this under MacOS X, without any luck, but plan to do this for Linux and MacOS X as well.

  I did see a few pre-compiled binaries that do this, and do not depend on extra libraries, but the versions I have found so far are either not the current version (1.x) or do not included the libraries in the executable (evermeet).

  I followed several guides (for example : FFMpeg MacOSX Compilation Guide, reneVolution), with or without the use of Brew, but none of these show me how to embed the libraries in the executable.
  I assume this is an option to be set for linking.

  I’m not sure if it’s appropriate to ask this question for Win, Mac and Linux at the same time - if it’s not appropriate : I’d like to start with doing this for the Mac version.

  My system runs MacOS X 10.9, XCode 5.0.2, with commandline tools and brew installed. I’m only looking for an Intel binary, so not a universal or PowerPC binary.

  For Windows I can use either Windows 8.1 or XP, for Linux I currently use Ubuntu 12, all of which are virtual machines.
