Problems about nvr on dm8168

Hi all:

We develop on dm8168 evm board using dvrrdk 4.0,

and we rewrite the nvr application, as we are newer in net video stream develop,

we have some problems,

in our nvr application we use it as a rtp server transmmit live capture video and h264 encode bit stream.

The server is based live555 which only used as a client in the original demos,

As we finished our job we found the stream can ben received  decoded and displayed when using

VLC player as URL:

rtsp://192.168.1.110:8551/h264_ch1

but when we use windows media player or some other player ,it could not paly any more.

So my first question is that

why other video stream player can not work , is there any other job we have to do 

for example to container the h264 bitstream before we send it ?

Sencod

If we want to public the bitstream using http protocal,

how to do then using live555?

best regards

xavier

    1. RTSP Tx in NVR app of DVR RDK 4.1 release is of alpha quality. Limited testing done with that module and the known issues are documented. Compliance testing with multiple players was not done.

    2. In 4.1 release, RTSP Tx module just feeds received video frames (RTSP In) to live555 server. Refer these functions - streamOutMain() function.
