[Live-devel] Problems with streaming live h264 video on TI da Vinci platform.

[Amit Lobo]

 Hi Ishwar,
Thanks for you help.
Are you using TI demo and live555 together?
Because my problem lies in the integration side.

About timer I dont think I am facing similar problem that you have
mentioned,because I have done test with reading video from the file.

Thanks & Regards

Amit
