And I agree with you, I don't know how to do this not from the
commanline. (that previous link shows command line parameters.) I wonder
how one could access this feature from a library.

Status in OpenShot Video Editor: Triaged

Bug description:
When previewing AVCHD (AVCHD is encoded in H.264) the video is extremely choppy, as well as the audio. Even playback of the media files in VLC Player is choppy. Doing a quick google search I found this. http://www.blog.arun-prabha.com/2010/03/02/how-to-play-m2ts-files-smoothly-using-vlc/ If "Skip the loop filter for H.264 decoding" is changed in VLC Player to BiDir it can play back smoothly. It decreases the video quality a little bit but plays smoothly. (And since this would be used for the preview, quality does not matter as much.) I think something like this might be available in OpenShot. (Does Openshot use the same H.264 libraries as VLC Player?) Anyway the preview is so choppy it is not is suitable for editing. The ACVHD clips were recoded at 17mbps. There are no effects or transitions on the clips.
