Memory leak #74

Open hig-dev opened 5 years ago

hig-dev commented 5 years ago

Steps to reproduce:

Hint: You have to enable native profiling and disable Just My Code in the memory profiling settings.

  1. Debug the sample app "VisualizationPlayer" with memory profiling
  2. Open a music file
  3. Force GC and make memory snapshot
  4. Repeatedly open the same or another music file. On every new opening of a music file the memory usage will increase. Do this 5-10 times.
  5. Force GC and make memory snapshot
  6. You will see that the memory usage has increased a lot.

I now found the exact source of the memory leak, after opening a music file, a new ring buffer will be allocated and the old one won't be released from memory: image
