Streaming - UDP vs RTP

Hello,

I've tested streaming of mpeg-ts file between 2 computers.
The file is in h.264, mpeg-ts format. I choose H.264+TS profile , deselect activate transcoding, and all stream all elementery streams.
I'm limited in bandwidth to 100M.
VLC version 2.2.1.

configuration for udp:
=====================
1st computer: send : 169.50.20.23:1234
2nd computer: listen to udp://@:1234

configuration for rtp:
=====================
1st computer: send : 169.50.20.23:5004
2nd computer: listen to rtp://@:5004



I've first streamed unicast udp the file, and it works very well.
Trying to stream in rtp (quite the same, just changed every udp, to rtp), I get some very noisy and unclear image.

Does anyone have any idea why rtp is not functioning ?
What are the main differences which can explaing this ?

Thank you,
Ran

udp and rtp are different, because they have different offsets. But both should work. it is a bug.

Right I moved to 32 bit version and both worked. Seems like bug in 64 version
