Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

Mac App (Cocoa) for producing HTTP Live Streaming
11 mars 2013, par MichaelI am building a Mac OS X application (Cocoa) with XCode that captures a video source and outputs the video through HTTP Live Streaming (HLS). After doing a fair amount of research I am thinking that I should be able to use the following stack of elements in my app to make this happen...
- AVCaptureDevice
- AVCaptureSession
- AVCaptureVideoDataOutput
- FFMPEG
- mediastreamsegmenter
- CocoaHTTPServer
I would really appreciate some feedback as to whether I'm on the right track, or correction if I am mistaken. Obviously any advice, pointers, perhaps some sample code snippets would be so very helpful.
Many thanks in advance !

Is it possible to update a filter option while paused in ffplay ?
25 juin 2020, par peggoI am using zmq to send filter option updates to ffplay while a video is playing. However, I would also like to be able to change say the zoom level while paused (I'm using scale and crop filters for this). If I do a zmq send command while paused nothing happens and I don't get a response.


If this is not possible, are there any workarounds ? I thought about using the loop filter instead of pausing, but I don't think you can change the options for that filter at runtime. So unless I know exactly where I want to pause in advance (which I don't) then I don't see a way to do this.


Thanks !
