source code transmit program

Post by on4bhm » Thu Nov 17, 2011 9:38 am

Hi,

I want to change the transmit program to automaticly captures the stream from my pvr15 card without writing it to a file first...
This way we won't need any other program to become air-born...

This program can than be extented with callsign display etc...

Is the source code of the current transmit program open source?

Can anyone help me?
i will sign a non-disclosure if neccesary.

kind regards
.net developer

I will probably make the source code freely available at some time. but not just at the moment. It needs a lot of 'cleaning' first. I use the Borland C++ 5.5 compiler. The program is written in C, not C++.

>>This program can than be extented with callsign display etc..

Could you give more details on that please. I'm not sure what you mean.

There is a version of DigiLite Transmit under test which uses GraphEdit to capture the program stream and send it to DigiLite Transmit via UDP networking protocol. This removes the need to write to disk and also means that you can have the PVR150 and camera on one PC and the DigiLite pcb and transmitter connected to another PC. In theory, you could do this over the internet if you had an uplink fast enough.

>This way we won't need any other program to become air-born...

Are you thinking about writing a DirectShow filter to interface with the PVR150 directly from DigiLite Transmit? That is the next logical step in development.

I think you could use an overlay, to display your callsign on the screen.

I was thinking of using this product to capture the mpeg2 stream:

i find gbpvr not so handy....
and my HD of my laptop is almost full. every time i TX, my HD get's 100% full.

Can i be you're beta tester for the transmit program?

kind regards

I'm not sure exactly what output that program would give, but it looks like you have to pay money for it.

I never thought I would fill a 350GB disk. :)

I'm putting together some instructions for this test version of the program. I'll let you know when they are ready.
