When I use IWMSyncReader::SetRangeByFrame(), if the start
frame or end frame is not given as 0, I always get
NS_E_INVALID_REQUEST(0xc00d002b).

Does anyone know what's wrong?

Please help, thanks a lot.

Rubing,

For frame number seeking to work, there must be a frame-number index on the
file. The frame-number index is _not_ generated by default. See the section
"Working with Indexes" for information on how to use the indexer object to
generate a frame-number index for a file.

Thanks,
Geoff

Geoff,

Thanks for your info. :-)

If I use "Windows Media Encoder" to convert a file to
wmv. How can I set Encoder to index the new file using
frame number index?

And, using WMF SDK, how can I set the writer to index the
file which is being writing to frame-number indexed?

You can add the index after the fle is created. As Geoff mentioned, use the
indexer object to add the type(s) of index you want to the file after you've
written it using the WMEncoder or FSDK Writer.

But, if I use the indexer object, IWMIndexer, to add
index, I found the file will be longer.

How to keep the file length when adding index using
indexer object?

I dont mean the file size. of coz file size will be
larger, but the duration, from IWMHeaderInfo interface
with g_wszWMDuration, shouldn't be longer than before
indexing. However, it does!

Is there anyway to indexing a file and the indexed file
can keep the duration same as the original file ??

Of course, the index itself takes up a small amount of
space, so your file
will be slightly longer after indexing. The increase in
size, though, is
expected to be pretty small.
