Hi all,

I'm hoping an Avid employee monitoring this forum might be able to tell me what the assertion referenced in this error message is checking for?

"* Exception: FATAL_ERROR, msg:Assertion failed: FALSE, file:..\..\src\msm\MPEG2GOPInfo.cpp, line:69."

Thank you in anticipation!!

Please complete your profile.Thanks!

Here it is: the calculated GOP size is less than or equal to zero.

AvBigByteCount_t thisGopOffset = pMapper->GetIndexOffset(firstSample*2);

AvBigByteCount_t nextGopOffset = pMapper->GetIndexOffset(nextIFrame*2);

AvBigByteCount_t GopSize =  nextGopOffset - thisGopOffset;

if (GopSize <= 0)  // something is wrong

{

       CoreEvent(DECODE_AND_FTC, 6, "CreateMPEG2GOPInfoFromMapper: bad GopSize, firstSample %d, offset %d, nextIFrame %d, offset %d, SampleNumDisplayOrder %d",

              (int)firstSample, (int)thisGopOffset, (int)nextIFrame, (int)nextGopOffset, SampleNumDisplayOrder);

       FtlAssertNotReached(); // LINE 69

}

The MC application uses a combination of GetSampleProperties(), GetNumberOfSamples(), GetSamplePosition() and GetSampleSize() from the AMA plugin to determine the GOP size; you should verify that the values returned by the AMA plug-in for these make sense.

Thank you. We'll give this a shot........
