I dont think it can be zero.
In the beginning of vl_video_buffer.c formats and return values are defined and resource_formats[0] is guranteed to not
be PIPE_FORMAT_NONE. The only other return value is null which caught immediately after requesting resource_formats
(line 59, in si_uvd.c).
So maybe
assert(resource_formats[0] == PIPE_FORMAT_NONE)
for debugging purposes?
