transcode and size problem

[cable007]

hi,

I have a problem with a transcode and size

I receive stream in udp then I transcode it again for http access.

Source is capture card and stream is in 720x576, when I connect myself
directly to the source (still with vlc) no problem
now when I catch source then I transcode it, then now I open http
stream from this last point, I get a window with full width screen !
whereas I should get same size as source => 720x576

what's the problem, do I need to add --width and --height options ?
ratio option ??? just to transcode (my relay)

look my log that I have on my computer (in that case, I get video with
width = 1280 !!!) :

I have met exactly the same problem with cable007
I am using vlc 1.0.2

two major issues:
1) aspect-ratio not right——incorrect width is the same as screen-width, this only happens when the source is 480p(720*480) or 576p(720*576). when the source is 720p(1280*720), the aspect is right
2) the first 5 to 10 seconds lost SPS/PPS thus not be able to play

could anyone can offer any help? I've be searching solutions for these for a few weeks
