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 (...) -

FFMPEG Kit issue in Banuba Video SDK : "FFmpegKit failed to start on brand"
10 mai 2023, par Vivek MakwanaI am trying to integrate Banuba Video Editor sdk in flutter.


The issue i am facing is as below


Banuba sdk works with native code for Android in Flutter


So Banuba requires FFMPEG dependency to define in Native Android


And I am already using 'ffmpeg_kit_flutter' plugin for flutter.


So both the FFMPEG kits are conflicted and some of the functions are not found. due to that I am receiving the below error.


When the app is launched I am receiving this Crash as mentioned


**java.lang.Error: FFmpegKit failed to start on brand: google, model: sdk_gphone_x86, device: generic_x86_arm, api level: 30, abis: x86 armeabi-v7a armeabi, 32bit abis: x86 armeabi-v7a armeabi, 64bit abis: .

Using ffmpeg to read mp4 file from stdin and extract image is failing with "Invalid data found when processing input"
16 mars 2023, par jsindosUsing ffmpeg, I'm trying to read an mp4 file from stdin, and save the last frame of the file to jpg.


cat PXL_20221118_051057924.TS.mp4 | ffmpeg -sseof -3 -i - -f mp4 -update 1 -q:v 1 last.jpg


The command works fine when not running from stdin.


When running from stdin, an empty file is created, with the following error message :


[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fcb4d0041c0] stream 1, offset 0x2eaee0d: partial file
pipe:: Invalid data found when processing input


I've posted the full output below.

Is there a way to cut movement "dead air" on a screen recording ? [closed]
16 mai 2023, par RaelbeI have got a couple of screen recordings of a painting I've done, and I've managed to concat the files together.


Unfortunately, there is a lot of "dead air" in the video (where I have left my desk, so there is no movement happening on screen) is there a way to cut out this down time ?


I found an example that another artist uses for his screen recordings, so I plugged it in with my file directory's. This is what I used :


.\ffmpeg -f concat -safe 0 -i "merge.txt" -vf npdecimate=hi=64*12:lo=64*5:frac=0.33,seipts=N/30/TB,"setpts=0.25*PTS" -r 30 -crf 30 -an Illu_Test.mp4


I got this error message at the end :


[AVFilterGraph @ 000001cadfe5b1c0] No option name near 'N/30/TB'
[AVFilterGraph @ 000001cadfe5b1c0] Error parsing a filter description around: ,setpts=0.25*PTS
[AVFilterGraph @ 000001cadfe5b1c0] Error parsing filterchain 'npdecimate=hi=64*12:lo=64*5:frac=0.33,seipts=N/30/TB,setpts=0.25*PTS' around: ,setpts=0.25*PTS
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0`


So I chopped it up a bit and this is what I used to concat the files and it worked perfectly.


.\ffmpeg -f concat -safe 0 -i "merge.txt" -crf 30 -an Illu_Test.mp4


Now, I'm looking to cut out the seconds of no movement. I'm unsure what the -crf command does (as stated I am brand new to this) OG artist states that :


"This is the tolerance level that determines whether there has been enough change between frames or not to be considered as detected motion."


Any help would be appreciated.


(Apologies if the format of this question is wrong)
