  • Keywords loco added
  • Reproduced by developer set
  • Status changed from new to open
  • Version changed from unspecified to git-master

I fixed the decoding, I wonder if this codec has to flipped or if this is only necessary because you encoded with VirtualDub?.

Replying to cehoyos:

The problem with flipped output happens only with RGBA mode, so if there is no other RGBA loco sample which decodes correctly I think it would be good to flip RGBA output.
