thanks, commited

what do you mean? it uses get_image() so it supports both methods.

btw, there is something called minilzo.c (although it isn't so mini)
which says itself as a derivate of liblzo. it's used by the nuppelvideo
codec as subcodec (it combines many realtime lossless video codecs).

could you upload some LZO samples to the ftp?

what about LZO encoding? (ve_lzo.c)
