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 ;

Why is the streaming fps is so large (about 600) when I do ffmpeg streaming a video file through udp ?
3 juillet 2014, par user1914692Ubuntu 12.04. ffmpeg version git-2013-03-26-1741fec Copyright (c) 2000-2013 the FFmpeg developers
The command I use is :
ffmpeg -i output_20140630.avi -f mpegts udp://192.168.1.56:1234
The streaming fps is about 600, shown in the same terminal.
If I use the command :
ffmpeg -i output_20140630.avi -f mpegts udp://236.0.0.1:200
Then it is fine. And I can use the command below to play the streamed video :
ffplay udp://236.0.0.1:2000

Video Conversion to have Play Speed
24 juin 2014, par TaufiqThere is a open source Media Player Component called Media Kit (https://wpfmediakit.codeplex.com/). It supports Play Speed. But its dependent on video format.
I have generated a video using SharpAvi (http://sharpavi.codeplex.com/) sample project, using Motion Jepg Encoder.
This video does not have Play Speed support for some reason. Details Below from ffmpeg
Video: mjpeg (MJPG / 0x47504A4D), yuvj420p(pc), 1920x1080 [SAR 96:96 DAR 16:9], 9818 kb/s, 10 fps, 10 tbr, 10 tbn, 10 tbc
Next I download an flv video from Youtube and Media Kit’s play speed works fine with this video.
Video: flv1, yuv420p, 426x240, 259 kb/s, 23.98 fps, 23.98 tbr, 1k tbn, 1k tbc
Now I converted them into common MP4 format using ffmepg
ffmpeg -i "1.avi" -ar 22050 -b 2048k "1.mp4"
ffmpeg -i "2.flv" -ar 22050 -b 2048k "2.mp4"Results
1.mp4
Video: h264 (High) (avc1 / 0x31637661), yuv420p, 426x240, 1235 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc (default)
2.mp4
Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc), 1920 x1080 [SAR 1:1 DAR 16:9], 158 kb/s, 10 fps, 10 tbr, 10240 tbn, 20 tbc (default)
The thing is the converted video from flv file still supports play speed where else the converted mp4 from the Avi does not. What is that I am missing
More Details Below.
