MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.

29 août 2014, par mkernI have installed ffmpeg and it works perfect if you are root or using sudo but it errors out when trying to use it as a non-root user. I have performed the same install on a test VPS and it installs without issue so it appears to be isolated to this cPanel server. I haven’t been able to identify why.

Skip intra mode tests depending on inter residualsThis commit allows encoder to skip intra coding mode test, when
the known inter residual is less than the source variance. It
reduces the runtime of speed 3 for test clips :
bus cif 1000 kbps : 8587 ms -> 8260 ms, 3.8% speed-up
pedestrian 1080p 2000 kbps : 161381 ms -> 155241 ms, 3.7% speed-up.The compression performance is down by

Skip comp inter mode tests for arf codingThis commit skips the compound inter mode prediction check in the
rate-distortion optimization loop for ARF coding. It reduces the
