"I'm trying to figure out how to get the time-of-day information that is
encoded in DV/HDV formats (and others?). This is variously called
datecode or datacode or time-of-day code.
...
I got the following suggestion: "You'll need to use GetMediaSmaple to
get a ptr to the dv data, then walk the DIF structure to find and parse
this. You'll likely need a copy of the SMPTE DV spec to figure out
where this data is stored..."
Can anyone suggest something simpler or (please, please) point to some
sample code?"
Some cryptic partial code here relating to walking the DIF structure....

You will need the appropriate SMPTE specs to make head or tail of this
SMPTE 314m is a good place to start, but curiously it does not mention
datecode at all, but it does describe the VAUX section. You'll have to
reverse engineer some DIF data with datecode in it to get any further.
