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 (...) -

avformat/matroskaenc : Only write Cues at the front if space has been reserved
2 mai 2020, par Andreas Rheinhardtavformat/matroskaenc : Only write Cues at the front if space has been reserved
If the AVIOContext for output was unseekable when writing the header,
no space for Cues would be reserved even if the reserve_index_space
option was used (because it is reasonable to expect that one can't seek
back to the beginning to write the Cues anyway). But if the AVIOContext
was seekable when writing the trailer, it was presumed that space for
the Cues had been reserved when the reserve_index_space option indicated
so even when it was not. As a result, the beginning of the file would be
overwritten.This commit fixes this : If the reserve_index_space option had been used
and no space has been reserved in advance because of unseekability when
writing the header, then no attempt to write Cues will be performed
when writing the trailer ; after all, writing them at the front is
impossible and writing them at the end is probably undesired.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
