When I use there a static local variable as counter and I print the thread id and counter I see in mpeg4 mode that the counts are continuously. In mpeg2 mode it happens that another thread has the same counter value. When I save this routine with mutex it does not happen. The behavior is the same as the mpeg4.</SPAN></div>
