[SDL] [SPAM] Re: Memory Leak

[Pankaj]

I am sure about them as memory leaks because if i run the application again and again then i am able notice with task manager that the memory application is usinng increases by 1 MB and i never get it back . When we run the same application again and again in the real device then also it dries down due to lack of memory. 


thanks,
Pankaj

Moreover , functions like SDL_OpenAudio are giving me huge memory leaks. It seems that if i run the applicaiton once and just decode a 3 minute tralior i am getting about 1MB of leaks which is unimaginable, all i am doing is using the ffmpeg library. Though i am using Rational Purify to check for the leaks but it only points to some functions like SDL_OpenAudio() othersiwe it just gives me some potetial leaks in AVCODEC library .

Are you sure these are leaks and not buffered datas?

I know that avcodec internally keeps some static buffers for a lot of 
stuff, OpenAudio creates a thread and inits one or more audio buffers 
that are released only by SDL_QuitSubsystem() or SDL_Quit(), one MB 
seems fair as buffering for audio/video in mpeg decoding.

If you decode for 6 minutes you have 2mb of leaks, if it doesn't grow 
with time you cannot be sure it's a leak.  Leak detection programs like 
valgrind or the Rational Purify you are using are mostly useful to check 
your code, it's very difficult to use them to check code you didn't know.
