Monitoring de fermes de MediaSPIP (et de SPIP tant qu’à faire)
31 mai 2013, parLorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.
Description des scripts
Trois scripts Munin ont été développés :
1. mediaspip_medias

Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

FFMPEG streaming ip cam get delay from start record to first frame
4 janvier 2019, par Vincent CarreteroI’m recording stream from IP CAM with FFMPEG.
I would like to know the exact timestamp when start the output video.Example :
I have an output mp4 file created at 2019/01/04 09:10:15 (file created).
FFMpeg take few seconds to really start streaming (initialising, etc...)
The first frame really start at 2019/01/04 09:10:19 (just supposed, I would like to get this info).Thanks !

Combining voices while considering their start time
21 juillet 2023, par user3405291Combine voices and add them to a video


I have this FFMPEG command to :


- 

- Remove current video audio.
- Combine some voices and add them to the video.






ffmpeg -i vid.mp4 -i voice1.mp3 -i voice2.mp3 -filter_complex "[1:a] [2:a] amix=inputs=2:duration=longest:dropout_transition=0" -c:v copy -an vid.mkv



The above command works great.


Each voice has a start time


I have a new requirement. Each voice should start at its own specific start time. Like :


- 

- Voice 1 starts at
2 sec
of the video. - Voice 2 starts at
1 sec
of the video.






How can I modify my FFMPEG command so that each voice would be at its own proper start time ?

ffmpeg exact start and end times
19 juin 2017, par Eng. M.HamdyI’ve searched a lot but didn’t find what I nedd.
I use this command :ffmpeg -ss <start> -i <srcfile> -t <duration> -c copy <dstfile>
</dstfile></duration></srcfile></start>to copy a part of the video, but the output file start time and duration may differ than "start" and "duration" specified.
I understand that ffmpeg seeks to the nearest Keyframe and that precise seeking to a timestamp is not possible unless re-encoding the video (I tried that but the output video losses quality !).
It’s important to me to know the exact start and end timestamp that ffmpeg use to generate the output, because I use this info to adjust subtitle timing.
Is there any way to make ffmpeg report start timestamp and end timestamp ?
Or else : Is there any way to know the previous and next keyframes to specific Timestamp, so I can adjust the video cut markers in my project to fit nearest keyframes ?
Thanks.Update :
Is it possible to seek to the second keyframe, and to the keyframe before the last one ?
what is the time interval between 2 keyframes ?
