SOLVED: hardware encoding fails

[XperiaPlay1998]

THX for this now i get permission denied.

Code:

Opening '/config/transcodes/83fbc6aa0fa9ebae5c8779074255ec480.ts' for writing
[hls @ 0x55cd836ea780] Failed to open file '/config/transcodes/83fbc6aa0fa9ebae5c8779074255ec480.ts'
av_interleaved_write_frame(): Permission denied

I know what this means but my linux/docker knowlage does not know how to fix this.
