Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

FFMpegm. Unable to get video stream from a onvif camera
15 avril 2018, par Denis GottardelloI have implemented ffmpeg in my own application to watch live video from video cameras.
I have tested my application with 2 models of onvif camera and the application works perfectly.
The customer has got another model of video cameram still onvif h264 but I can’t watch the live stream.
I can wath it using vlc but when I try to watch it with my application I obtain the following error :Input #0, rtsp, from 'rtsp://admin:admin@172.30.153.33:554/1':
Metadata:
title : h264.mp4
Duration: N/A, bitrate: 64 kb/s
Stream #0:0: Video: h264, none, 90k tbr, 90k tbn, 180k tbc
Stream #0:1: Audio: pcm_mulaw, 8000 Hz, 1 channels, s16, 64 kb/s
[rtsp @ 0x7f86b8004e00] UDP timeout, retrying with TCP
[rtsp @ 0x7f86b8004e00] method PAUSE failed: 455 Method Not Valid In This State
[rtsp @ 0x7f86b8005000] Could not find codec parameters for stream 0 (Video: h264, none): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' optionsI have already tried to modify analyzeduration and probesize without any good result.
How to resolve this error ?
Could it be caused by a not up-to-date h264 library ? -

Video compression - DirectShow
11 juin 2013, par EdoardoI'm generating a video (.AVI) that last about 1 minutes for 150MB of size on 320x240 mode.
The size is really big, and I can't upload it efficiently.After the recording application has finished How could I compress the video without displaying a window ?
I recently installed FFMPEG and with this command :ffmpeg -i input.avi -s 320x240 -vcodec msmpeg4v2 output.avi
I can take the video to 3MB ! I must say fantastic !
But... How could I do this from the inside of my application ?
It would really be better doing this while the application is recording, whiutout installing ffmpeg, and not after.I'm now reading http://msdn.microsoft.com/en-us/library/windows/desktop/dd374572(v=vs.85).aspx
Is this the right page to read ?
