Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

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 ?
