#10250: libx265 -x265-params no-temporal-layers value not recognized
-------------------------------------+-------------------------------------
Reporter: AY Columbia | Type: defect

**Summary of the bug:** passing the "non-value" x265 param no-temporal-
layers as "no-temporal-layers=1" is not recognized as valid per following
message displayed when encoding is started. I tried setting to 0 as well
with the same result.
{{{
[libx265 @ 0000020bdd835240] Invalid value for no-temporal-layers: 1.
}}}
**How to reproduce:**
I use an h264 1080p source in an MKV.

Note that I checked with MediaInfo and the ''Encoding settings'' did list
"temporal-layers=0" but not sure if that's essentially the same as using
no-temporal-layers.
Please let me know if you need anything else or if I'm not doing something
correctly in the command. Thank you.
