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.

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.
