The lyrics at the top make sense neither in French (either old nor modern) or in Occitan (ditto). The two verses in Old Oc Reinhard posted mean...

Since we see that Winter is getting irritated
And is moving away from the time of love,
Since I no longer hear any songs
Nor bird songs by the leafy orchards,
For the cold of the dark winter
I will not stop composing a poem
And I will say which are my desires,
And I will say,and I will say which are my desires.
