    Hi everyone.

    When I run this command:

    player --xv --disable-pc-audio --nona-split --source-aspect 16:9 --hide-progress-bar --enable-term-keyb --udp-in 239.255.1.1:2000 --udp-in 239.255.1.1:2001 
    

    I get this output and only show the first channel

    The UDP Address is: 239.255.1.1 and the port is: 2000 
    Joined multicast group for 239.255.1.1 port 2000
    Reading video parameters from multicast stream... width=640 height=360 framerate=25/1 audio_size=7680 packets_per_frame=241 frame_number=138549 source_name="PGM"
    The UDP Address is: 239.255.1.1 and the port is: 2001 
    Joined multicast group for 239.255.1.1 port 2001

    Notice the "Info: Failed to pass through connect stream 6 (picture, yuv420)"

    When I run this command:

    player --xv --disable-pc-audio --quad-split --source-aspect 16:9 --hide-progress-bar --enable-term-keyb --udp-in 239.255.1.1:2000 --udp-in 239.255.1.1:2001
    

    I get this output and show the two channels

    The UDP Address is: 239.255.1.1 and the port is: 2000 
    Joined multicast group for 239.255.1.1 port 2000
    Reading video parameters from multicast stream... width=640 height=360 framerate=25/1 audio_size=7680 packets_per_frame=241 frame_number=147025 source_name="PGM"

    The only change from one command to another is the "--nona-split" option. The nona-split its working fine with shared memory and file inputs.

    Any ideias about this.

    Solved, some of the definitions I'm using can not be divided by 3.
