Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -

OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error
19 avril, par user2262504I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.



It seems that OpenCV invoke ffmpeg API using default parameters and ffmpeg invoke x264 using its default parameters. Then these setting is broken for libx264. Thus the "Could not open codec 'libx264'" error.



Anyone has ideas to solve this problem ?



More specifically :



- 

- anyone knows where and how OpenCV invoke ffmpeg API ?
- how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV ?
- will changes of default in ffmpeg be carried to libx264 ?









Errors :



1. Uising CV_FOURCC('H', '2', '6', '4')

Live555 : X264 Stream Live source based on "testOnDemandRTSPServer"
26 octobre 2017, par user2660369I am trying to create a rtsp Server that streams the OpenGL output of my program. I had a look at How to write a Live555 FramedSource to allow me to stream H.264 live, but I need the stream to be unicast. So I had a look at testOnDemandRTSPServer. Using the same Code fails. To my understanding I need to provide memory in which I store my h264 frames so the OnDemandServer can read them on Demand.
