How can I transcode different program with different option

[johnnyauyeung]

Hi,

May I know whether anyone have transcode different program of a frequency with different bit rate?
I can transcode all programs of a frequency with a single transcode setting by using this command:
c:vlc -vvv dvb-t://frequency=482000000 :dvb-adapter=0 :programs=1,2,3,4 :
sout=#transcode{vcodec=h264,vb=1000,scale=1.0}:duplicate{
dst=udp{dst=239.190.1.1:1234,sap,group=G1,name=P1},select=program=1,
dst=udp{dst=239.190.1.2:1234,sap,group=G1,name=P2},select=program=2,
dst=udp{dst=239.190.1.3:1234,sap,group=G1,name=P3},select=program=3,
dst=udp{dst=239.190.1.4:1234,sap,group=G1,name=P4},select=program=4} :ttl=3 :sout-keep

However, I want to have P1,P3 and P4 using 1Mbps w/o scale but P2 with 1.5Mbps with scale 0.5.
What should I do? Do I need two tuners for that?
