IGEP Firmware Yocto uses the following Ethernet network configuration ==== DM3730: Decode an WMA audio file (IP addressesOK)====
*eth0 − 192.168.5.1*eth0:0 − assigned via dhcp. <pre>bitbake gst-ffmpeg</pre>
This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine<pre>gst-launch -v filesrc location=sample.
