[vlc-devel] [PATCH 3/3] video_filter: opengl: fix error handling

[Romain Vimont]

There were 2 problems:
 - if sys->filters could not be created, then vlc_gl_filters_Delete()
   was called, causing a segfault;
 - if the requested filters could not be loaded, then
   vlc_gl_filters_Delete() was not called, leaking sys->filters.
