Hi. I'm trying to get lan streaming to work.

In DD v1.4h I have set Options->Preferences->Lan Streaming->UDP TS Client to 127.0.0.1, Port 1234
PAT Override is on.
Buffer size is 18kb
Active is checked.

In VLC v0.8.6d, I have file->open network stream->UDP/RTP Port 1234.

Windows firewall has been disabled. No other firewall is installed.

Unfortunately I get no video, no audio.

If I look at view/Stream and Media Info, I see no information under general, no information under advanced information, and under Statistics I see:

Input:
Read at media (constantly increases)
Input bitrate: 2725 kb/s
Demuxed: 0 kb
Stream bitrate: 0kb/s

All other statistics are 0.

If I go to VLC Settings->Add Interface->Debug logging, I see

libdvbpsi error (PSI decoder): TS duplicate (received 0, expected 1) for PID 0

over and over again.


Can anyone help me with this? Thanks.

I have tried unicast and broadcast to my.ip.at.255 as well as your method above and VLC won't play. Even more confounding because MyTheatre streams so beautifully from this machine. Message console for VLC on broadcast is as follows:

BUMP. Same situation here. (Tested DD 1.4h, 1.4iP1, with and without PAT override)

I would really love to transcode a live stream to the outside world, but I get exactly the same issues mentioned above when trying to use VLC (on both localhost and remote). Tested with VLC 0.8.1, 0.8.6c, and 0.8.6e. At least 0.8.6x shows incoming bytes in the status window. Saving the 'Raw Stream' to a file yields a corrupt MPG for me as well. I've also tweaked the MTU and cache settings to no avail.
EDIT: Spoke too soon. I don't know what changed as my VLC preferences appear to have defaulted again, but suddenly VLC 086e will dump raw streams which contain good MPG data regardless of PAT override. I've tried forwarding the raw stream without success. The libdvbpsi log messages vary:
PAT override ON: TS duplicate (received 0, expected 1) for PID x
PAT override OFF: TS discontinuity (received 4, expected 0) for PID x

I can have DD record in renderless mode and use VLC's ability to play 'in-use' files to stream the file while its recording, but thats a rather inelegant solution for things like channel changing.

Of course MPC 6.4.9.0 works brilliantly (sourceforge.net/projects/guliverkli2/), so I guess that implies DD is not to blame. Too bad MPC can't transcode and stream on-the-fly like VLC. Curious side-note: renderless DD + streaming to MPC uses only about 1/3 of the CPU as DD alone (when rendering) - and the video parameters are correct for FFDshow (framerate, framesize)!
Edit: After disabling MPC's internal mpeg2 'transform filter' and using ffdshow the CPU usage was about 2/3 of 'normal'.
