Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

Revision 5ab920d2ae : Using local variable for token_cache. The difference with the old code is that
3 décembre 2013, par Dmitry KovalevChanged Paths :
Modify /vp9/decoder/vp9_decodeframe.c
Modify /vp9/decoder/vp9_detokenize.c
Modify /vp9/decoder/vp9_detokenize.h
Modify /vp9/decoder/vp9_onyxd_int.h
Using local variable for token_cache.The difference with the old code is that originally the whole token_cache
was initialized with zeros at the beginning of decode_coefs() function.
Now we set several zero values explicitly with "token_cache[scan[c]] = 0".Change-Id : I88cc5031f01d13012d1a4491739c36cb44f9401e

FFMPEG performance when reading directly from s3 vs local
16 janvier 2020, par user1147070I have a usecase where I need to transcode a s3 file. I have two options
Option a : Download the file to local, then run ffmpeg on it
Option b : Provide a presigned URL as ffmpeg input eg -
"./ffmpeg -loglevel debug -y -i "https://mybucket/key?signedParams" -threads 0 -map_chapters -1 -f mp4 -movflags faststart -map 0:0 -acodec libfdk_aac -ac 2 -ar 44100 -b:a 48k -sn -vn /output.mp4"I tried running both and comparing the time but I don’t see any much performance improvement in #b as compared to #a.
I have 2 questions
-
Is #b is better in performance than #a ? Or both of them are same ?
-
In case of #b does ffmpeg wait for complete download and then start transcoding or it start downloading and transcoding simultaneously ?
