Memory leak in MPEG2VideoDecoderBase?

I think I found a small memory leak in MPEG2VideoDecoderBase:

In the beginning MPEG2VideoDecoderBase::Init() will call BaseCodec::Init().
If the initialization parameter of BaseCodecParams->lpMemoryAllocator is set to NULL, then BaseCodec::Init() will create an own instance of DefaultMemoryAllocator for m_pMemoryAllocator and m_bOwnAllocator is set to true.
In the further processing of MPEG2VideoDecoderBase::Init() the method Reset() is called which will set m_bOwnAllocator to false.
The result is that m_pMemoryAllocator will never be freed.

Daniel

Thanks Daniel,

I'll forward this info to ourdevelopers. By the way what version of IPP do you use? Is that the latest IPP 5.3 release?

Vladimir

It really happened and was fixed before IPP 5.2 gold.

Thanks,

I'm using the IPP-samples 5.3.083 (but that part of the code identical to that of version 5.3.095)
