[Mp4-tech] [H.264] Redundant Slices in JM10.2

[Alex Converse]

Dear experts,
Sorry if this is a duplicate message my list confirmation came in later 
than I expected.
Using the JM110.2 reference software encoding and decoding a baseline 
stream using the following commands:
$ ./lencod.exe -d encoder_baseline.cfg
$ ./ldecod.exe
encodes and decodes a stream properly.
Trying again with redundant slices, using the following commands:
$ ./lencod.exe -d encoder_baseline.cfg -p UseRedundantSlice=1
$ ./ldecod.exe
gives me a "mb_qp_delta is out of range" error on the decoding process
before finishing the first frame. Is this the expected behavior? Am I
misusing the encoder or decoder? I know redundant slices exist largely
for helping decoders decode non-conformant streams but if the stream is
otherwise conformant shouldn't it decode properly?
Thanks,
Alex Converse
