udpsink/udpsrc on win32 (Vista)

Hi all,

Has anyone successfully used udpsink and udpsrc on win32 (Vista) using the GStreamer Winbuild?

I'm testing a simple pipeline

> gst-inspect-0.10.exe --gst-debug-level=3 videotestsrc ! udpsink port=5000

I'm see the following messages continuously being printed in the log

0:00:00.966000000 ←[335m 4240←[00m 01BA7008 ←[33;01mWARN ←[00m ←[00m mu

ltiudpsink gstmultiudpsink.c:416:gst_multiudpsink_render:<udpsink0>←[00m client

01B616F8 gave error 0 (No error)

I have looked at the multiudpsink_render source code and printed the following out:

0:00:00.965000000 ←[335m 4240←[00m 01BA7008 ←[33;01mWARN ←[00m ←[00m mu

ltiudpsink gstmultiudpsink.c:402:gst_multiudpsink_render:<udpsink0>←[00m SO_MAX_

MSG_SIZE = 65527 and BUFFER SIZE = 153600

It seems that the SO_MAX_MSG_SIZE of the datagram socket is set to 65527 bytes but the buffer being sent is 153600 bytes, so the sendto() call failed because the buffer exceeds the socket message size.

Does anyone have a workaround? Is there any way to control the buffer size upstream?

Thanks.

William

You can only send 65536 bytes with udp, the output of videotestsrc is
likely bigger. You might want to reduce the framerate or do application
level framing by using RTP or so.

In reply to this post by William Lee-7

Thanks for the advice. I would really appreciate if someone has an example pipeline I can try. I tried using ffenc_h263p followed by rtph263ppay with mtu value set to various values, however I still can't get the the packet sent through udpsink.

Many thanks.

Re: udpsink/udpsrc on win32 (Vista)

Hi all,

I'm answering my own question here.

I have managed to use RTP to control the framing on Windows XP and stream from an XP box to a Vista box. However, I cannot yet do the same on Vista.

What I notice is that when I stream using RTP with "udpsink port=5000 host=localhost" with debug level set to 5, I can indeed see the packet sent to the loopback device.

0:05:09.228000000 3428 02D2EB78 LOG multiudpsink gstmultiudpsink.c:

385:gst_multiudpsink_render:<udpsink0> about to send 1000 bytes

0:05:09.231000000 3428 02D2EB78 LOG multiudpsink gstmultiudpsink.c:

392:gst_multiudpsink_render:<udpsink0> sending 1000 bytes to client 00A9D980

0:05:09.234000000 3428 02D2EB78 LOG multiudpsink gstmultiudpsink.c:

425:gst_multiudpsink_render:<udpsink0> sent 1000 bytes to 1 (of 1) clients

However, if I try to send to another host "udpsink port=5000 host=192.168.0.2", the following error can be observed:

385:gst_multiudpsink_render:<udpsink0> about to send 1000 bytes

0:05:48.531000000 456 01EFE2F0 LOG multiudpsink gstmultiudpsink.c:

392:gst_multiudpsink_render:<udpsink0> sending 1000 bytes to client 00A9D9C0

0:05:48.534000000 456 01EFE2F0 WARN multiudpsink gstmultiudpsink.c:

410:gst_multiudpsink_render:<udpsink0> client 00A9D9C0 gave error 0 (No error)

0:05:48.537000000 456 01EFE2F0 LOG multiudpsink gstmultiudpsink.c:

425:gst_multiudpsink_render:<udpsink0> sent 1000 bytes to 0 (of 1) clients

I'm not sure what's causing the sendto() error. I'm pretty sure the size of the buffer is below the max size allowed for the socket. Is it anything to do with IPv4 / IPv6 and multiple network interfaces? Anyone any idea?

William,

I believe udpsink is broken on trunk, on at least macos and windows.

I wrote a patch, here: http://bugzilla.gnome.org/show_bug.cgi?id=534243

I have not tested it on Vista - could you do so? That'd be a big help.
It's also awaiting code review.

Mike

Hi Mike,

Will do. I have also traced the code down to that point. I should have searched the bug report ;)
