Thanks again for your hard work.
I'm not planning to deliver daily builds to LTS users, but will keep your patch to maybe use it when 20.04 will be out?

Is this now relevant now that 20.04 has been out for a while?
Comment 3 Vincent PINON 2020-11-13 21:09:50 UTC 
Sorry with this patch kdenlive was compiling but not working properly, so I removed the bianries from the ppa after receiving several complains shortly after publication
