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 ;

When I run
ffprobe rtp://239.1.1.1:8000
(without restarting the stream), around one in ten times I get

 Stream #0:0: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 384 kb/s



Meaning that the video and audio streams swapped indices. I'm writing a program which uses
libav
where I rely on this to not happen. What is the reason for this and can it be fixed ?

Download RTSP recording content between two dates and times, or from start seconds to end seconds
23 septembre 2022, par holt2I need to download from an RTSP link the content recorded on an IP camera from a start and end date and time. It would also be valid to be able to download it from X seconds of start of the recording to seconds of end.


With this
ffmpeg
command I download the recording content from the RTSP link only from the beginning of the recording content, with the duration in seconds passed by the-t
parameter :

ffmpeg -rtsp_transport tcp -i -r 30 -t <seconds> -y -vf scale=800:-1 -c:v libx264 -crf 20 -preset fast -c:a aac -strict experimental -b:a 192k -ac 2 /path/to/video/filename.mp4
</seconds>


I tried to download with
ffmpeg
the content using temporary media fragment URIs (https://www.w3.org/2008/WebVideo/Fragments/wiki/UA_Server_RTSP_Communication#.281.29_Temporal_Media_Fragment_URIs) but it doesn't do it correctly :

ffmpeg -rtsp_transport tcp -i #t=10,20 -r 30 -y -vf scale=800:-1 -c:v libx264 -crf 20 -preset fast -c:a aac -strict experimental -b:a 192k -ac 2 -ss 19:09:13 -t 5 /path/to/video/filename.mp4



I have also tried with
ffmpeg
to use the-ss
parameter to try to extract the recording from a specific hour, minute and second (https://trac.ffmpeg.org/wiki/Seeking) but when running it gets stuck, it does not advance :

ffmpeg -rtsp_transport tcp -i -r 30 -y -vf scale=800:-1 -c:v libx264 -crf 20 -preset fast -c:a aac -strict experimental -b:a 192k -ac 2 -ss 19:09:13 -t <seconds> /path/to/video/filename.mp4
</seconds>


In case it's helpful, to get the RTSP link, I'm using the ONVIF protocol with a NodeJS library (https://github.com/agsh/onvif). I have also reviewed the ONVIF documentation available but have not found a way to download recorded content between start and end dates and times.


Do you know how to download from an RTSP link the content recorded on an IP camera from a start date and time and end date, or download it from X seconds of recording start to seconds of end ?


I am also open to use other tools or commands that can do this.
