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 (...) -

Mixing two audio inputs together as fast as possible ffmpeg
23 septembre 2016, par JeremyCurrently trying to mix two audio streams together to perform an overlay. (Vocals over Instruments). I have two M4A files and I want to combine them together. If the vocal track is 30 seconds, it takes roughly 32 seconds to mix them together, but was hoping for significantly faster processing.
Here is the code I’m using
-ss 0.300 -i /data/user/0/me.rapchat.rapchat/cache/recording.m4a -i /data/user/0/me.rapchat.rapchat/cache/beats/cc3613da-849b-47a5-97b1-b9bf3f1136db.m4a -filter_complex [0:a][1:a]amerge=inputs=2,pan=stereo|c0data/user/0/me.rapchat.rapchat/cache/rap.m4aI’ve read about using the preset Ultrafast but not sure how it would fit in as I’ve tried adding it and gotten errors about it’s placement in the command. I’ve also read about copying the stream "as is" and not worrying about encoding/decoding which I was curious if that would speed up the whole process.
And here are my logs for a succesful mix

I’m pretty new to FFMPEG and the syntax has quite the learning curve when throwing in presets, and codecs. Will the preset ultrafast be what i’m looking for, and how do I add it to this ?
Thank you in advance !

FFMPEG Unable to Decode Quicktime QDMC Stream (No decoder for stream)
9 janvier 2017, par mbmastWe are using FFMPEG to convert iPhone video to MP4. This requires an AAC decoder which is not included in any binary distributions of FFMPEG (due to licensing issues). The solution is to download the FFMPEG source and compile it yourself. I’ve done this, apparently incorrectly, as I cannot decode the audio stream. I am getting this error :

No decoder for stream #0:1, filtering impossible
Error opening filters!I suspect that I failed to compile and include the correct codec library when I built FFMPEG. The problem is I don’t know which library I should have built/included. I haven’t found anything that says to decode QDMC audio in FFMPEG you need the XXXXX library.
Here’s the complete list of decoders that my build supports :
