Comment (by jkqxz):

 "format=FOO,hwupload,unsharp_opencl,hwdownload,format=FOO", same FOO in
 both cases.

 The filter format negotiation doesn't have the information to see what
 format it needs to pick as the output of hwdownload, because it doesn't
 know what the thing before it will produce yet.
