Hey,
Sorry for the late replay, the thing is I am able to decode the same data on
my windows machine
but not on Linux...
and more over I am getting errors on the SPS and PPS ("no frame!") -> this
is a very early phase
there are no frames yet, I think the decoder is trying to say he does not
support multi-slice
Could be ?
