Re: [Opensvcdecoder-support] How to speed up decoding?

Hi, Guys,
I used JSVM 9.19.10(beta) Encoder to encode a video with mixed CGS/MGS
configuration. There are 3 resolutions 320x180, 640x360, 1280x720 with
total number of 8 layers. when I use opensvcdecoder to decode, an error is
prompted "A layer is using a different scan for residual block" in
SliceHeaderExtension.c:306.
I use MGS setting in configure file as following:
MGSVectorMode 1 # Write coefficients into multiple
slices
MGSVector0 8 # Number of coefficients that are
contained in slice 1
MGSVector1 8 # Number of coefficients that are
contained in slice 2
Is there anything wrong with the configuration?
profile & level info:
=====================
DQ= 0: Main @ Level 1.2
DQ= 1: Scalable High @ Level 1.3 320x180
DQ= 2: Scalable High @ Level 1.3
DQ= 16: Scalable High @ Level 3
DQ= 17: Scalable High @ Level 3.1
DQ= 18: Scalable High @ Level 3.1
DQ= 32: Scalable High @ Level 4
DQ= 33: Scalable High @ Level 4
# I do not know why JSVM shows wrong resolution 320x192, 640x368, but the
JSVM decoded resolution is right.
