Q. Does anybody know which Codec Engine API call opens the device /dev/cmem and the DSP/ARM trace files (cearmlog.txt, cedsp0log.txt, bioslog.dat) ? I observed that these files are getting opened but not being closed. In my application i play many video clips, each time these files are getting opened with different file descriptors (observed in "lsof" tool), after some time the application crashes. I suspect opening these files multiple times is causing the problem, once it reaches the maximum number of file descriptors. A. CMEM_init() is called from the auto-generated CERuntime_init() when the app's .cfg configures the ti.sdo.ce.osal.Global.runtimeEnv to DSPLINK_LINUX. This is typically the case for an ARM-based Linux application. The trace files are opened during TraceUtil_init(), also called by CERuntime_init() when the app's .cfg configures the ti.sdo.ce.osal.Global.runtimeEnv to DSPLINK_LINUX _and_ uses the 'ti.sdo.ce.utils.trace.TraceUtil' module. CMEM_exit() and TraceUtil_exit() are called when the application exits. If your application never exits, these handles will never be closed... but I don't think new ones should be 'opened'. [ Additionally, FYI, in CE 1.20 we are introducing CERuntime_exit() for customers that need to explicitly close all resources CE was using before exiting their application. ] I guess I can't explain what you're seeing. Can you provide further details about how your app is using CE (lots of Engine_open/closes, or just VIDENC_create/delete's, any 'interesting' threading going on, etc.).
