AU_Splitter::m_Headers leak

dplong — Wed, 16 May 2012 22:00:02 GMT

The tool, Visual Leak Detector, is reporting memory leaks from AU_Splitter::m_Headers (see below for output). Assuming this is a real leak, does anyone know how this could happen?

I'm using IPP version 7.0, build 205 with Visual Studio 2005. My code calls H264VideoDecoder::Init() before each decode session and afterwards calls H264VideoDecoder::Reset() then H264VideoDecoder::Close(). VLD reports one each of these UMC::Headers member variables leaking for each decode session.

HeaderSet m_SeqParams;
HeaderSet m_SeqExParams;
HeaderSet m_PicParams;
HeaderSet m_SEIParams;

AU_Splitter::m_Headers leak

SergeyKostrov — Wed, 16 May 2012 23:55:06 GMT

Quoting dplong

The tool, Visual Leak Detector, is reporting memory leaks from AU_Splitter::m_Headers (see below for output). Assuming this is a real leak, does anyone know how this could happen?...

A generic explanation ofMemory Leaks could look like:

Some piece of code allocated a memory block and the memory wasnever released

Why?

ASoftware Developer forgot to implement a code that releasesthe memory, or a code that releases
the memory wasn't executed.

Best regards,
Sergey

Hi,

Could you in general describe your decoding cycle?

I.e.

Allocate

Init

GetFrame

Reset

GetFrame

...

We'd like to know what model of decoding to check.

Thanks,

Sergey

AU_Splitter::m_Headers leak

I just noticed this in the release notes for "IPP v7.0 update4 (29 Apr 2011)." Could it be related to the leak I am seeing?
