Hi all,

I found  a two problems today testing both VLC ver 2.0.5 and 2.0.6 in Ubuntu.

1/ logo overlay problem when streaming a UDP TS, this happens when I transcode video files from a common folder one after another. The first file has the logo overlay in the picture all other been play out after that do not. In older versions VLC once you set the overlay it stays displayed for all video files been streamed out.  This what I'm using below:

vlc  --random '/media/XFS/Videos' :sout='#transcode{vcodec=mp2v,vb=4608,keyint=27,bframes=2,fps=25,width=720,height=576,sfilter=logo,acodec=mp2a,ab=320,channels=2,samplerate=48000,threads=8}
:standard{access=udp,mux=ts,dst=}' :sout-keep

2/ VLM multiplexer no longer works I am no longer able to remap PIDs such as below:

new channel1 broadcast enabled 

setup channel1 input "udp://@:1231 :udp-caching=500" 

setup channel1 output #std{access=udp,mux=ts,dst=,name="TS 1",}
setup channel1 option sout-ts-program-pmt=102
setup channel1 option sout-ts-pid-audio=101 

setup channel1 option sout-ts-pid-video=100 

setup channel1 option sout-ts-sdtdesc="TS 1" 

setup channel1 option sout-ts-netid=40 

control channel1 play  

new channel2 broadcast enabled
setup channel2 input "udp://@:1232 :udp-caching=500" 

setup channel2 output #std{access=udp,mux=ts,dst=,name="TS 2",} 

setup channel2 option sout-ts-program-pmt=202
setup channel2 option sout-ts-pid-audio=201
setup channel2 option sout-ts-pid-video=200
setup channel2 option sout-ts-sdtdesc="TS 2" 

setup channel2 option sout-ts-netid=40
control channel2 play

Has the way that VLC does a multiplex change in anyway? I do a lot of work with DVB TS and multiplexing so thiscourses me a few problems when using VLC for testing these days.
