  • Resolution set to fixed
  • Status changed from new to closed

We have a sample now thanks to this and the decoder side warning is no more so this probably should be closed
or is there some other reason to keep this open ?
btw thanks for the sample!
(and if theres some reason, dont hesitate to reopen)
