Wish: Lossless macroblock padding

[richfife]

Add the ability to pad video files losslessly by adding blank macroblocks around the edges. For TVs that have problems with overscan for instance.

If this is a valid enhancement request, it is imo libavcodec-related.

1. Why won't-fix?

2. Any chance to reconsider? My use case is that I have 1440x1080 AVC/h.264 video that should be displayed with a 4:3 aspect ratio (which would correspond to square pixels). I'd like to burn it to a Blu-ray disc to be playable in Blu-ray players, but my understanding is that Blu-ray specifies that 1440x1080 video should be treated as 16:9 (which makes no sense to me, but I digress). I would love to be able to add pillarboxing to make the frame size 1920x1080 without lossily re-encoding the existing content.
