Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

What is the best way to split a transport stream file ?
27 mars 2016, par scaryguyI have a .ts file (Download files here : http://dropcanvas.com/2gmsg/1).
I want to split this video while I expect ALL other properties remain same including pts time.
Here is what I try to achieve this :
ffmpeg -ss 0.000 -i sample.ts -y -c copy -t 3 splitted.ts
Expected start time : 94678.950389
New start time : 1.402367I expect the above command should only take first 3 seconds of the .ts file and all other stuff to stay same. I’ve seen copyts and copytb options from the documentation but I wasn’t able to use them.
So how do I do this ?
Thank you
Here are the logs for copyts. It creates a 0 byte splitted.ts file :
ffmpeg -ss 0:00:00 -i sample.ts -to 00:00:03 -y -c copy -copyts splitted.ts

FFMPEG no audio get recorded from RTSP stream
22 mars 2016, par HarisI am trying to record rtsp stream on HLS format. I need to record both audio and video. Using below command the video and audio get recorded for some stream like a test rtsp stream from Internet rtsp ://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov. Where as for my IP camera it doesn’t work, means the video get recorded but no audio on output file.
./ffmpeg -i rtsp://10.0.8.152:554/media/live/1/1 -acodec copy -vcodec copy -hls_list_size 65535 -hls_time 2 "./live.m3u8"
Here is the command line output for my IP camera while start recording with above command.
