Hi,
i noticed that sometimes pixbufs producers stop caching converted
images and do conversion on each get_image call. i found that it
happens because of cached pixbuf, image and alpha been dropped from
cache because of cache limit.
attached patch implement extending limit of that cache.
1.) Change MLT_GTK2_PRODUCER_CACHE to MLT_PIXBUF_CACHE as this only
affects pixbuf, of which there is only a producer. I strongly doubt that
we will ever have a pixbuf consumer because the avformat consumer works
fine for images.
2.) Needs to be documented in the yml.
please review updated patch
