Socket: Webcam broadcasting

Islamegy®

Hiiiiiii
I'm working on a client server application which work like messnger.. I was
able to capture the camera with no problem but now i want my my program to
listen to incoming connection and start sending..

I'm using UPDClient (I think TCP is not the right protocol to send video
stream) and i send it via NetworkStream but no luck..
I'm new in network and socket programming but i was able to send text and
images but no luck with vedio..
Am i use the right protocol UDP?? is there any article which may help me??
thanx

[PD] Actually you should use RTP protocol - an UDP based protocol designed
to send real time data like audio and video. There is a free library in
C++ to send data with RTP - jrtplib. But that's only beginning. To send
video data efectively you should encode it and pack in the RTP packets in
a specific way. You sholud look at H.263, H.261, H.264 or MPEG4 codecs,
that are usually used for video conferencing. Than you should look at
RFC's for packing the encoded data into RTP packets (H.263 over RTP, H.261
over RTP etc).
Probably you don't want to write all this by yourself - you can look at
some existing solutions like
http://www.elecard.com/products/comp...product_id=191
(unfortunatelly only MPEG2 streaming :( ) or JMF (unfortunatelly Java only
:( ).
There is also good solution from Microsoft you can use if you are not
interested in interoperabilit y with the rest of the world:

socket problem

by: Gordon Wetzstein | last post by:

Hello everyone, I have a problem with python sockets. I broadcast a lot of pickled objects with socket. sendto(...), that works. Ireceive them on the other site with socket.recvfrom(16384) The pickled objects are smaller (like 10000 bytes) than the max bytes. The problem appears if I send too many pickled objects very quickly one after another, then I only receive a part of the sent objects.

Hi, I've written a very simple 'kill-server' to help me shut down processes through Telnet or HTTP. The kill-server is a function and is launched as a thread. I use the module socket.py on Python v2.3 (Windows) I can use telnet host:port and enter the secret killword or use a broser with http://host:port/secret_killword The 'kill-server' validates the secret_killword and writes a file

If this is the wrong group for this posting please let me know and I'll move it. I have an application that has an ArrayList of sockets to clients. For standard one-to-one messages my application works great, the problem is if I want to "broadcast" a message to all my clients. Right now I just iterate through my sockets list and send the message to each client. This works fine until I need to send something large like a file. Is there a...

Raw socket three way handshake

by: Marco | last post by:

I have a problem with the establishement of a three way handshake through raw socket. The problem is that if in my application client I use the syscall socket(AF_INET,SOCK_RAW,IPPROTO_RAW) the kernel will refuse the server answer because there isn't a CONNECTED socket. So I used the syscall connect() but if I want sent another TCP packet I need to know the sequence number that the connect() has utilized and the ack from the server and...
