If anyone has any objections, please let me know. ------------------ From: Timur Kristóf [ Upstream commit 8246147f1fbaed522b8bcc02ca34e4260747dcfb ] On some GPUs the VBIOS just doesn't have encoder caps, or maybe not for every encoder. This isn't really a problem and it's handled well, so let's not litter the logs with it.
