31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source

Possible to Combine Live m3u8 stream with PIP overlay from WebRTC source ?
25 octobre 2015, par user1258530Can someone tell me what server-side technology (perhaps ffmpeg), one could use in order to :
1) display this full-screen live-streaming video :
http://aolhdshls-lh.akamaihd.net/i/gould_1@134793/master.m3u8
2) and overlay it in the lower-right corner with a live video coming from a webRTC video-chat stream ?
3) and send that combined stream into a new m3u8 live-stream
4) Note that it needs to be a server-side solution - - - cannot launch multiple video players in this case (needs to pass the resulting stream to SmartTV’s which only have one video-decoder at a time)
The closest example I’ve found so far is this article :
https://trac.ffmpeg.org/wiki/Create%20a%20mosaic%20out%20of%20several%20input%20videos
Which isn’t really live, nor is it really doing overlays.
any advice is greatly appreciated.

ffmpeg split video H264 stutters on Windows Media Player
9 mars 2019, par Juan FoegenI am converting and splitting wmv and mp4 into new mp4 files. I am using ffmpeg to do the conversion with simply :
ffmpeg -i inputfile.wmv -vcodec libx264 -ss 00:00:10 -t 00:00:15 outputfile.mp4So when I create my split video it plays fine on other video players, like VLC, but stutters when initially playing on Windows Media Player and even shows a blank screen for a moment and then after about 5 seconds, the video will play normally. If I then select play again without reloading, Windows Media Player will play the video fine, with no stuttering.
If I REMOVE the start parameter when doing the conversion, then the resulting video will play without issues on all my players, INCLUDING Windows Media Player.
I have tried changing the frame rate, the bit rate and altered different optimization options mentioned here - https://trac.ffmpeg.org/wiki/Encode/H.264
I need the split video to play on Windows machines on Windows Media Player and on the web streamed using the video element. This is why I chose H264 codec and MP4.
Has anyone had issues playing ffmpeg split videos using H264 codec with Windows Media Player ? I am using the latest version of ffmpeg. Anyone have any other suggestions on any different settings I could try to adjust ?
Thanks
