I know from the developers maillists thats its possible to use Sony SNC cams with VLC.
See developer posts by Laurent Aimar and Steve MOREAU

I change the stream size to 0 in the "Content-Length" part of the
modules/access/http.c (line 1111) file :
int64_t taille = i_tell + atoll(p);
p_access->info.i_size = (taille != 556 ? taille : 0);
and it works with my Sony SNCM1W stream
