La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

How to apply effects to RGB frame decoded using ffmpeg ?
23 juillet 2014, par user3665376I wanted to apply changes in contrast,brightness,saturation values of a video while rendering on android.I am using ffmpeg for decoding my mpeg4 video.
I have two options for applying the effects ,
1) Apply the changes on raw YUV frames .
2) Apply the changes to RGB frames which are created from raw YUV frames .
Which of the above is the best approach ?
I started with option 2 and found a utility function at libwscale/util.c which has the below signature.
int sws_setColorspaceDetails(struct SwsContext *c, const int inv_table[4],
int srcRange, const int table[4], int dstRange,
int brightness, int contrast, int saturation);but the parameter specification of the above function was difficult to understand. Can anybody do a little elaboration on the parameters use in this function ?
