I try to play UDP stream by LibVLC in Android Box but I have some problem. The above assumes that there is a multicast stream on a multicast group with ip address of 238.1.1.1 on port 5000. In a multicast configuration the Encoder/Gateway sends the UDP stream to a multicast group, such as: 238.1.1.1. vlc -vvv video1.mp4 --sout=#transcode{vcodec=h264,vb=800,acodec=mpga,ab=128,channels=2,samplerate=44100}:udp{mux=ts,dst=224.0.0.1:1234} But when I start a 2nd vlc instance with: Code: Select all. So to do this I went to Start -> Control Panel\System and Security\System -> “Advanced system settings” -> Environment Variables and then under “System variables” I added C:\Qt\5.1.0\mingw48_32\bin to the end of the variable value, as illustrated in Figure 5. I use a libvlcnet c sharp wrapper that play a stream (udp). The downside is often that solutions are not well packaged and often need customisation to work with recent libraries. In these setups I am using the regular VLC player to receive and display the video streams (RTP, UDP unicast and UDP multicast). VLC needs to be configured to lisiten for incoming streams on a specific port. So, within the folder C:\Qt\libvlc-qt\src\examples\ there is a folder called demo-player, which I am going to use for the rest of this example. Simply press the green play button on the bottom left. I have the same problem. Opening this within QtCreator gives the following output as displayed in Figure 1. Please tell em how to compile vlc-qt from source. 2. Does anybody have an idea why?

The project uses two different Transport Layer Protocols(TCP/IP & UDP) for communicating different data.And uses two way communication for fetching radio list(TCP) and other for streaming service(UDP). If you built a device to run object tracking, would you enable a videoplayer to run on the beaglebone or just use wireless streaming as in your example to view the tracking and even record the stream onto the home pc, when its online? this is my Vlc Controller class: The VideoLAN streaming solution includes two programs: VLC media player which can be used as a server and as a client to stream and receive network streams. In most cases the first thing we do is ask the customer to confirm that their setup works with VLC, because if it works with VLC then their issue is most likely not IP networking related. Everything is nice. For Eg: in the script file streamVideoRTP, can the line “./capture -F -o -c0|avconv -re -i – -vcodec copy -f rtp rtp://192.168.1.4:1234” be modified in someway to achieve this?
