Hi

  I am trying to build an AAF that descibes a SMPTE 436 data track with essence.  I found the kAAFDataDef, but when I try to create the essense with:

 

AAFRESULT res = pMasterMob->CreateEssence(1, // Slot ID within MasterMob

pDataDef, // MediaKind

kAAFCodecDataType2, // codecID

editRate, // edit rate

sampleRate, // sample rate

kAAFCompressionDisable,

NULL, // No Locator used

ContainerAAF, // Essence embedded in AAF file

&pEssenceAccess); // object returned

i get a AAFRESULT_CODEC_INVALID no matter what codec (or Nul/Nil codec) I use.  What is the correct 'codec' type for these essence? Cheers, James

 

I'm working with James offline to collect the details.  I'll post a followup.
