Vlc cannot show video with changing resolution?
That's a weird title, for a weird video file! This file seems to somehow change resolution while playing.
Vlc only shows a black image and plays the audio stream.
Is this a valid video file, or does it stretch the spec too much and there is no correct playback behaviour? ffplay does show the video stream.
