One is an FF_PROFILE_*, the other is a VAProfile* - I think it's better to use the FF_PROFILE_* values in messages, because they match what is actually in the stream (profile_idc, etc.).  Maybe the first of the paired messages should also be WARNING too, so that it makes more sense with default level (info) output.
