who gives a blit?

I used the “who gives a blit?” article on the qnx website to write some
code which displays video frames. It works fine, except when I place a
window on top of my video display window, photon crashes. Any ideas why
that happens?

thanks

Hello Kale

Would it be possible for you to send me an example that illustrates this
problem?

Thanks,
Rodney

Hello,
Even i tried using the article, got the following problem when i executed
this program. Its displaying
“PgCreateVideoChannel: No such device or address.”
what could be the problem ? should i run any driver for this ?
And i want to display the mpeg 4 decoded video strem which is in YUV/RGB
format. So, where should i specify the image data and how to do it
It would be of great help if anybody can give me some input in this
regard.

Thanks in advance.
