Comment:
Can't reproduce it on my side (Linux), and I don't think the regression is
caused by QVBR since your log show that your are working on AVBR mode
instead of QVBR.
Probably it is that your MSDK version can't support coding option 3.
1. Could you please tell me what is your MSDK API version and library
version.
2. Apply the patch:
-#define QSV_HAVE_CO3 QSV_VERSION_ATLEAST(1, 11)
+#define QSV_HAVE_CO3 0
Don't change anything else.
3. If it is possible, update your MSDK version can try again.
