[Opensvcdecoder-support] Fwd: OSVC unable to decode a video that JSVM can

Hello,

I'm having trouble with a .264 file that JSVM decodes fine that OSVC won't.
Any help would be greatly appreciated, as always. I hope it is just
something in my config file not supported by OSVC that can easily be
avoided.

I have a small h.264 SVC video- foreman0.264 (8 frames of foreman) with 3
layers and no loss.

Both JSVM and OSVC decode it fine.

I use JSVM's BitStreamExtractorStatic32 to produce a .264 file with only
the base layer. (foremansBase.264)

I also drop all packets except those of the base layer in my network
simulation. (decInp.264)

So I have 2 files that should just be the base layer, with no loss
otherwise.

Both decode fine in JSVM, producing foremansBase.yuv and decInp.yuv
(terribly quality due to high qp, but valid).

However, OSVC produces corrupt results look like diagonal lines of the
image (openSVCOut0.yuv). I have verified that it looks the same when I play
it in MPlayer as included with OSVC, so it is OSVC and not my code for
feeding OSVC.

All files plus the config files are attached, or at

Here is the profile and level info from encoding:

profile & level info:

Thank you for any help or insight you can offer,
