Hi,
I am facing quite strange issue with multi-app case.(DirectFB is build with multiapp support and fusion is also enabled) My hardware has multiple layers- Graphics, Image and Video . I have 2 applications one is using Graphics and other is using Video. Case 1) Both created with directfb cooperative level(DFBCooperativeLevel) DFSCL_FULLSCREEN and display layer co-operative level(DFBDisplayLayerCooperativeLevel) to DLSCL_EXCLUSIVE. When run as standalone..not simultaneously.. both are working fine. But when run one after another (first Graphics and then video- simulteneously), Video application crashes with "--> Caught signal 11" - (Assumption [(lock)-> addr != NULL || !((lock)->access & (CSAF_CPU_SREAD|CSAF_CPU_WRITE))] fail]) But run first video and then Graphics application..both work fine Case 2) So for video application, I set directfb cooperative level(DFBCooperativeLevel) to DFSCL_NORMAL and display layer co-operatie level(DFBDisplayLayerCooperativeLevel) to DLSCL_ADMINISTRATIVE. With this applications both applications are running fine simultaneously.. but my video is not getting displayed, through it is getting decoded in background. This i even tested with running only video application. So not the case of video behind Graphics layer. I read this in Directfb ..GetSurface - is only available in exclusive mode. I dont get any errors on this API. But is there any issue here? Same surface i pass it to directfb for rendering video. Same application with (DFBDisplayLayerCooperativeLevel) to DLSCL_EXCLUSIVE, video is getting displayed. But with this mode set in video, case is similar to Case-1 Any issues with the way, I should handle layers in multi-app build? Also is there any documentation or guideline for understanding the proper way to access the directfb interface and layers in multiapp scenario.
