Hi I need opens source (win 32) sdk or free server with signaling protocol, which implements RTP translator or mixer. e.g receives RTP traffic from one connection and transmits it on the other. Does not have to have conferencing capabilities.
Server should implement some kind of protocol which opens, bridges, and closes connections.
Ready made server is much preferable than just common RTP SDK.
Use ffmpeg - ffserver
I haven't found nothing real.
RtpProxy approaches the goal but I wasn't able to use it because it is for linux only.
I tweaked Rtp Relay test program included in Live555
look at VLC
look at the command line option of VLC

I'm trying to find a proper way how to reuse existing implementations of wifi tools(iw) in own code(c\c++). I need to get information about available AccessPoints in range(signal strength, mac addr., etc). I found couple example codes(WEXT and others) that uses ioctl approach, but it makes passive scans(and i get new information only once in two minutes in my network)[UPDATE1: Thanks to #fluter, i know that WEXT can do active scanning, too.]. I found that iw makes an active scan and that is what i need. So my question:
Is there a way to use iw code in my own app without parsing its source code in chunks, or, maybe, there is an Wireless API for such purpose?
(UPDATE1: with basic code examples to start with.)
Similar question
UPDATE2: I have reviewed my task and found that AP information is not enough for me, i need to capture clients data, too. That leads me to wifi packet sniffing and the best tool i have found to do that is Horst. So, i'm trying to reuse its code in my app, now.
You might wish to start with cfg80211.
cfg80211 replaces Wireless-Extensions and it is suggested that :
All new Linux wireless drivers should be written targeting either cfg80211 for fullmac devices or mac80211 for softmac devices.
Also, it is written:
Instead of writing wext ioctls you now write cfg80211 operation
callbacks and fill in the wiphy struct to indicate to cfg80211 its
device capabilities.
To start with active scanning start here
You can use the wext api provided by kernel, basically, call ioctl with SIOCSIWSCAN, and get the scanned result with SIOCGIWSCAN.
You can set to scan all by using flag IW_SCAN_ALL_ESSID, and choose scan type with flag IW_SCAN_TYPE_ACTIVE or IW_SCAN_TYPE_PASSIVE.

I am looking for an Open Source MTP (Media Transfer Protocol) responder implementation for BeagleBone boards. Alternatively, an embedded Linux implementation that includes an MTP responder implementation.
Note, this is not the same as the MTP initiator as found with gmtp and similar.
take a look here:
from buteo project
1) https://git.merproject.org/mer-core/buteo-mtp
from ubuntu
2) http://bazaar.launchpad.net/~phablet-team/mtp/trunk/files
or android
3)https://android.googlesource.com/platform/frameworks/base/+/master/media/jni/
i have already got ubuntu and buteo-version both running on BBB.
Another MTP responder have been developed recently :
https://github.com/viveris/uMTP-Responder
Implemented in C, in user space and use the GadgetFs layer.
This wasn't tested yet on BeagleBone but this shouldn't be a problem. You just have to change the gadgetFS settings in the config file.
More details on the github project page.

Language: C++
IDE: Microsoft Visual Studio 2010
Hardware setup:
Machine[rs232]---> [rs232 to usb] ---> [usb]Computer
Data being sent:
Result information as ascii text.
I am trying to access the ascii data that is coming in from the machine's rs232 port into the computer's usb port.
How do I open the connection and start listening for this data?
I have some experience with network programming, which was as simple as listening on the correct port# for packets from the server. But, I'm unsure what to do to listen for data coming in on usb or from rs232 for that matter... Very new to receiving data in this fashion.
The CreateFile and ReadFile APIs are used to open and read a serial port (even if it comes from USB). See the MSDN article titled "Serial Communications in Win32"

Hi I am trying to write a windows virtual com port driver which will divert the data to a IP address. any pointers, best practice will be of help?
I know of a Open source project called com0com which is virtual com port redirector. there is a subproject called com2tcp in that which you can look atcom0com. otherwise for windows I am not sure you have any open source available
Between there are commercially available software such as the one from Eltima and tactical software. there are few freewares too, you can search by the name comport redirector.
Check out this example of a User Mode Driver from Microsoft:
Archive.org -> Microsoft.com: Virtual serial driver sample (FakeModem)
Github.com/Microsoft : Virtual serial driver sample (FakeModem)
You can take a look at the open source project Null-modem emulator (com0com) which includes a COM port to TCP redirector.
you can look at the software development kit from Constellation Data Systems, Inc.

I need something a little more feature rich than Sysinternals TCPView (which I regularly use) ... but it also must be freeware. :)
Well, the question is a bit old and I realize that probably you already found the software you were looking for... just in case, an interesting connection monitor utility is CurrPorts, by Nir Sofer.
Freely adapted from the program's home page:
displays the list of all currently opened TCP/IP and UDP ports on your local computer;
for each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it;
allows you to close unwanted TCP connections, and kill the process that opened the ports;
allows custom filters for inclusion/exclusion of connections.
Maybe a full blown traffic sniffer like Wireshark will complement your tool set?
Amongst wiresharks features are:
packet analysis
traffic statistics
capture
coloring
data export
I recommend TCPView for Windows v2.53.
image http://i.technet.microsoft.com/bb897437.TcpView(en-us,MSDN.10).gif
TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.
Not sure what features you are looking for so this is my suggestion.
Without having used it, I have seen TCPStat advertised a few times.
It looks like it was a discontinued project somewhere around 2003 and it's an awful blue color.
There's the MS Network Monitor.
Process Hacker shows also send/receive bytes, speed, country flag etc.
