Swscale doesn't seem to work properly in vlc. To be more exact it works, but upscales video to the same resolution it already had. Here is an extract from a log.
720x384 chroma: I420 -> 720x384 chroma:Scaling with Bicubic (good quality)
Tried with opengl/direct3d output. How can I make it work?

Re: Swscale doesn't work
How is it a bug ? swscale scale and does chroma conversion.

Re: Swscale doesn't work
The resolution remains the same. It shouldn´t be so. There´s no sense in such 'scaling'.

720x384 chroma: I420 -> 720x384. The resolution remains 720x384. It should change as a result of upscaling.

No. It changes the chroma. Read my message.
