samples: video: tcpserversink: video compression support

hfruchet-st · erwango · commit 6d23a89e6deb · 2025-10-01T12:19:53.000+02:00
Add video compression support to lowerize network bandwidth.

To visualise camera content on host PC, use GStreamer command line:
$&gt; gst-launch-1.0 tcpclientsrc host=&lt;board ip address&gt; port=5000 ! decodebin ! autovideosink sync=false
