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 (...) -

Could not find com.arthenica:ffmpeg-kit-full:6.0-2
23 juin, par gabocaleroI started receiving this message when I build my project


> Could not find com.arthenica:ffmpeg-kit-full:6.0-2.
 Searched in the following locations:
 - https://dl.google.com/dl/android/maven2/com/arthenica/ffmpeg-kit-full/6.0-2/ffmpeg-kit-full-6.0-2.pom

 Required by:
 project :presentation > project :domain



These are the project's repositories


allprojects { 
 repositories {
 google()
 mavenCentral()
 jcenter()
 maven { url 'https://jitpack.io' }
 maven { url "https://oss.sonatype.org/content/repositories/snapshots" } 
 } 
}



And this is the dependency I'm adding


implementation(libs.arthenica.ffmpeg.full)



This is my libs.version.toml


ffmpeg = "6.0-2"
arthenica-ffmpeg-full = { group = "com.arthenica", name = "ffmpeg-kit-full", version.ref = "ffmpeg" }



AFAICS in the project's github page, it will not be maintained anymore



In the short term, do you know any other repository that still servers this dependency ?


On the other hand, do you know any other project to replace Arthenica ffmpeg-kit-full dependency ?


Thank you very much

Use nvidia hardware acceleration to merge webms with pngs in ffmpeg
2 février, par Joshi234So I need to merge around 18000 webms with with pngs, however on software encoding it's really slow, so I'm trying to use hardware acceleration to make this faster.


I tried a lot of different stuff but none of them seems to work and it gives me generic errors to what I couldn't find anything relavant.


This is the most "succesful" try I had :

ffmpeg -hwaccel cuvid -c:v vp9_cuvid -i lightray.webm -i card.png -filter_complex "[1]format=argb,colorchannelmixer=aa=0.35[ol];[0][ol]overlay" -colorspace 5 -c:a copy output.webm


Which gives me this error :

I'm by no means an expert in ffmpeg or in video encoding in general, so I have no idea what this is supposed to mean.

RTMP Disconnects quickly when the stream is turned on and No index.m3u8 files are being generated in the assigned directory [closed]

These are the logs, ffmpeg pushes the stream in a different folder when tried manually.


- 

- I tried changing the location of my file outside of oneDrive to avoid any permission conflicts.
- Manually checked if FFmpeg is correct with this command :
C:\ffmpeg\bin\ffmpeg.exe -i rtmp://localhost/live/test -c:v copy -c:a aac -f hls -hls_time 2 -hls_list_size 5 -hls_flags delete_segments output/index.m3u8
- Downgraded NMS to a stable version.
