Right now if you change lowres property on a ffmpeg decoder while a pipeline is running you see the video change size but not the xvimagesink window. It seems that buffers size is not changed.
Comment 1 Wim Taymans 2010-05-13 08:51:40 UTC 
xvimagesink does not change the window size after it has created its window, AFAIK.
Comment 2 Luca Ognibene 2010-05-13 08:58:33 UTC 
i think it's more a problem in ffmpeg, it doesn't work even with fakesink. Right now i set the decoder to READY, change lowres and back to PLAYING and it seems to work fine (i don't use xvimagesink in my app).
Comment 3 David Schleef 2011-06-01 00:31:31 UTC 
There is no point to the lowres property.  Only intra formats benefit from half-size decoding at all, and only Dirac and DV benefit more than a tiny amount.  Everything else just downscales after decoding.

Do you still want this?

No, we don't really care about this in 2013.
