First question, is there supposed to have three kind of multicast in veejay ?

  • frame sender
  • vims control
  • osc control

updated systemd multicast setup (no sure of this also :-( ):

firewall accept all traffic (debian default) checked with # iptables -L

# /sbin/ip link set lo multicast on
# /sbin/ip link set lo up
# /sbin/ip route add 224.0.0.0/4 dev lo
# echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
# echo 1 > /proc/sys/net/ipv4/ip_forward

$ ping 224.0.0.1 ---> OK

$ export VEEJAY_MCAST_INTERFACE="lo" In all terminals (vj1 / vj2 / sayVIMS)

First Case

vj1 : veejay TreeStomper.avi -T 224.0.0.1 -p 5000 -v -a0

I: TCP/IP unicast VIMS control socket ready at port 5000 (R:2097152, S:2097152)
D: env VEEJAY_SERVER_RECEIVE_BUFFER_SIZE=[num bytes] not set
D: env VEEJAY_LOG_NET_IO=logfile not set
D: env VEEJAY_NET_TIMEOUT=seconds not set
D: Port: 5001 [ receive buffer is 2097152 bytes, send buffer is 2097152 bytes ]
I: TCP/IP unicast VIMS status socket ready at port 5001 (R:2097152, S:2097152)
D: env VEEJAY_SERVER_RECEIVE_BUFFER_SIZE=[num bytes] not set
D: env VEEJAY_LOG_NET_IO=logfile not set
D: env VEEJAY_NET_TIMEOUT=seconds not set
D: Port: 5005 [ receive buffer is 2097152 bytes, send buffer is 2097152 bytes ]
I: TCP/IP unicast VIMS control socket ready at port 5005 (R:2097152, S:2097152)
D: env VEEJAY_SERVER_RECEIVE_BUFFER_SIZE=[num bytes] not set
D: env VEEJAY_LOG_NET_IO=logfile not set
D: env VEEJAY_NET_TIMEOUT=seconds not set
I: UDP multicast frame sender ready at (group '224.0.0.1')
I: UDP unicast OSC channel ready at port 5006

vj 2 : veejay -d -W 1024 -H 576 -v -a0

$ echo "246:5000 224.0.0.1;" |sayVIMS + [F2]

I: New Input Stream 'Multicast' with ID 2 created
I: Created new input stream [2] (multicast) to veejay host 224.0.0.1 port 5000
I: Playing stream 2 (FX=0) (Ff=50)
I:  ... Waiting for network stream to become ready [224.0.0.1]
I: Connecton established with 224.0.0.1:5005

but vj2 screen remain black (and did not respond to keyboard)

Second Case

vj1 : veejay -g video01.avi --multicast-vims 224.0.0.1 -v -a0
vj2 : veejay -g video02.avi --multicast-vims 224.0.0.1 -v -a0
sayVIMS -g 224.0.0.1 -m "600:;"

Nothing happen.

frame sender
vims control
osc control

Yes, supposedly, all three should work in multicast; incl. VIMS messages up to VIMS ID 400

If it's broke, I'll fix it - Thanks a lot!

Took up issue

First case:

Frame sender was not started
Before opening stream on veejay 3490, send "022:;"| sayVIMS -p 5000
--> Will make change to automatically start frame sender on veejay 5000

Second case:

It appears that VIMS messages are not handled when received via multicast
