--- Comment #5 from Mitten Orvan <mitte...@gmail.com> --- I added a debug print that output &self from producer_avformat_close. I was able to catch a situation where the self in producer_open was the same address after it was closed. So somehow the producer is being closed while it is being opened. I suspect the guilty stack is libmltavformat.so!producer_avformat_close(producer_avformat self) (/home/keski/code/others/mlt/src/modules/avformat/producer_avformat.c:3117) libmlt-7.so.7!cache_object_close(mlt_cache cache, void * object, void * data) (/home/keski/code/others/mlt/src/framework/mlt_cache.c:142) libmlt-7.so.7!mlt_cache_item_close(mlt_cache_item item) (/home/keski/code/others/mlt/src/framework/mlt_cache.c:185) libmlt-7.so.7!clear_property(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:113) libmlt-7.so.7!mlt_property_close(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:912) libmlt-7.so.7!mlt_properties_close(mlt_properties self) (/home/keski/code/others/mlt/src/framework/mlt_properties.c:1506) libmlt-7.so.7!mlt_frame_close(mlt_frame self) (/home/keski/code/others/mlt/src/framework/mlt_frame.c:768) libmlt-7.so.7!clear_property(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:113) libmlt-7.so.7!mlt_property_close(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:912) libmlt-7.so.7!mlt_properties_close(mlt_properties self) (/home/keski/code/others/mlt/src/framework/mlt_properties.c:1506) libmlt-7.so.7!mlt_frame_close(mlt_frame self) (/home/keski/code/others/mlt/src/framework/mlt_frame.c:768) libmlt-7.so.7!clear_property(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:113) libmlt-7.so.7!mlt_property_close(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:912) libmlt-7.so.7!mlt_properties_close(mlt_properties self) (/home/keski/code/others/mlt/src/framework/mlt_properties.c:1506) libmlt-7.so.7!mlt_frame_close(mlt_frame self) (/home/keski/code/others/mlt/src/framework/mlt_frame.c:768) libmlt-7.so.7!clear_property(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:113) libmlt-7.so.7!mlt_property_close(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:912) libmlt-7.so.7!mlt_properties_close(mlt_properties self) (/home/keski/code/others/mlt/src/framework/mlt_properties.c:1506) libmlt-7.so.7!mlt_frame_close(mlt_frame self) (/home/keski/code/others/mlt/src/framework/mlt_frame.c:768) libmlt-7.so.7!clear_property(mlt_property self) (/home/keski/code/others/mlt/src/framework/mlt_property.c:113) I don't have the stack of the closing that did it, because I had no way to know in advance which closing was the one whose producer would be used after it. But most closing seemed to be done by the above stack. So somehow the cache item is being destroyed while it is still in use? -- You are receiving this mail because: You are watching all bug changes.
