4 Early Decoding Demo

A demo was provided to test this use case. VISION SDK reads an h264 video data from u-boot, then sends the decode link for decoding. The use case is shown in Figure 4-1. After running Linux, you can play the video using the gstreamer.

PSDKLA can run gstreamer, command as below: 

gst-launch-1.0 playbin uri=file:///home/root/test.mp4 video-sink=waylandsink
