7.1. Function Overview¶
7.1.1. Objective¶
Video encoding provides real-time video compression of input video signals using standard video codecs to reduce data size and provide video services for the application layer.
The currently supported input sources are:
Image data input by user under User Mode
The video input (VI) module sends the image directly to the encoder
The video input (VI) module receives the image, which is then processed by the video processing subsystem (VPSS) and sent to the encoder for encoding
Supported video standards currently include:
JPEG
MJPEG
H.264
H.265
