[winklejude]

good everyone

i had got a command line
"D:\Program Files\VideoLAN\VLC\vlc.exe" -vvv "udp://@234.1.1.114:10000" --sout "#standard{mux=ts{pid-pmt=100,pid-video=101,pid-audio=102},access=udp,dst=234.10.10.114:10000}" --sout-all --sout-keep --loop

and now i want use the Audio channel remapper (remap) to change the audio channel of the origin stream, like use the left channel from the stream and mapped into two channels output.

but use "--aout-remap-channel-left={0}" add it to the command line won't work.

how could i use this options correctly？

You can't remap channels without transcoding.
