The VideoLAN Forums

Hi All, looking for some help to solve my multicasting issues...here is the environment

Laptop running ubuntu 11.10, vlc 2.0, multicasting on local lan thru kr2 router that supports igmp,

Trying to multicast to 239.16.6.6:1234, using following string in vlc
vlc -vvv pvr:///dev/video0 :bitrate=7000000 :maxbitrate=8000000 --sout '#standard{access=udp,mux=ts,dst=239.16.6.6:1234}' --ttl 1 --cr-average 10000
utilizing the hd pvr from hauppage as source device.

vlc starts streaming and shows locally, but when i try to access the stream from a different laptop using vlc it wont connect.

Is there a way in ubuntu to show if it is actually going out??

in media information in vlc it shows the data being processed however nothing being output
in netstat it doesnt show the stream in network services, or multicast.

What else can i use to determine if it is actually going out to network?? and how do i fix this issue.

Any help would be extremely helpful.

sudo iptraf

command not found

ubuntu 11.10 terminal comes back that this command is not found??

any other ideas...

Ok so i have managed to get the file to start streaming thru lan with following command

cat /dev/video1 | ffmpeg -i - -vcodec copy -sameq -acodec copy -f mpegts udp://239.16.6.6:1234

now i get black screen on receiving pc it sees the stream but cannot play video

sending machine states

main warning: trying to send non-dated packet to stream output!

any ideas??

This is what i get when i try to use v4l2

v4l2 warning: Could not select any of the default chromas; attempting to open as MPEG encoder card (access)
v4l2 warning: Unable to query for frame sizes
v4l2 warning: Unable to query for frame sizes

ts warning: first packet for pid=4113 cc=0x3
ts warning: first packet for pid=4352 cc=0xe
main error: cannot add this stream
main error: cannot create packetizer output (s16l)

also is there a command line to force vlc to record from the hd pvr composite input???

I could not get this to work only the component inputs worked

Is there a command line out there that should work for me??? i have tried all of the following:

vlc -vvv pvr:///dev/video0 :bitrate=7000000 :maxbitrate=8000000 --sout '#standard{access=udp,mux=ts,dst=239.16.6.6:1234}' --ttl 1 --cr-average 10000
Does not seem to go to LAN

cat /dev/video0 | ffmpeg -i - -vcodec copy -sameq -acodec copy -f mpegts udp://127.0.0.1:1234 ----this one works... but black screen only on client end, has
main warning: trying to send non-dated packet to stream output!


vlc udp://@224.1.1.1:1234 -vv --sout-mux-caching=5000 --sout "#standard{access=udp,mux=ts,dst=239.16.6.6:1234}" –ttl 5 –cr-average 10000
does not work

cat /dev/video0 :bitrate=7000000 :maxbitrate=8000000 --sout '#standard{access=udp,mux=ts,dst=239.16.6.6:1234}' --ttl 1 --cr-average 10000
does not work

vlc -vvv 4l2:////dev/video1 | ffmpeg -i - -vcodec copy -sameq -acodec copy -f mpegts udp://239.16.6.6:1234
creates above errors...

Im really getting frustrated have exhausted a lot of different options to no avail....any help would be extremely appreciated.
