"swresample" is an FFMEG filter which is not available due to instability. How do you enable this filter?

Comment 4 Vincent PINON 2020-10-14 20:30:06 UTC 
the resampling is needed for speed change.
the speed effect is implemented in MLT & ffmpeg
4000% speed change is uncommon, probably it leads to unexpected situations
sorry but I can't track down this bug
