Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Why does my linux ffmpeg output file require running it back through ffmpeg to play on windows
13 septembre 2020, par Sean MillerI am using the following to screen capture a Raspberry Pi display :


/usr/bin/ffmpeg -v quiet -f lavfi -i anullsrc -f x11grab -framerate 30 -video_size 720x480 -i :0.0 -f flv -b:v 1M /home/pi/usbdrv/myfile.avi"



I stop screen capturing by hitting the letter q and ffmpeg exits without error.


I can play it back with mplayer in Linux.


However, when I try to play it back on Windows with the old media player or its newer movie player, they reports it is corrupted. I tried mp4 and mkv fromats as well.


If I run it back through ffmpeg to encode it to a new file, it will play.


Any thoughts why Windows will not play it without running it back through ffmpeg again ?


Thanks,
Sean

Matlab - Capture Video Streams (part 2)
25 novembre 2014, par Uri MerhavThis is a follow up on this question. I’m trying to capture a live stream from an ip address (e.g. rtsp ://10.0.0.0:554/live.sdp). The only solution I’ve seen so far is to use mexopencv to call opencv’s streaming functionality from matlab. This has a very significant drawback, in that you need to get mexopencv to actually work on a mac, which is quite challenging.
So, I was thinking about using the following approach :
- Use ffmpeg to stream the rtsp stream into a named pipe
- Read the named pipe from Matlab, just as if it was an ordinary video file (am I correct that this is how one uses a named pipe ? I’ve never used this kind of solution before)
If this solution is inefficient, not going to work, or if there’s a better alternative — I’d love to hear about it !
