Description Marcus Sundman 2018-03-22 00:11:25 UTC

In the Atadenoise filter the av.s frame count parameter can only be 5. If set to anything else the result is not denoised properly. Sometimes the beginning of the video gets included twice.

Steps to reproduce:
1. Add the Atadenoise filter to a noisy clip.
2. Set Atadenoise's av.s value to, say, 6.
3. Render.

Expected results: 6 frame averaging denoising.

Actual results: No denoising. Possibly starting with a duplicate section of the beginning of the clip.

MLT: 6.7.0
Kubuntu: 18.04

Thanks for report and sorry for huge answer delay.
Since then we have worked on better handling of avfilter plugins, but also identifying all the broken plugins in our setups and hide them from the list.
