RDK-C : RDK Integrating libcamera into PipeWire

Why libcamera in PipeWire?

Standardized interface: Libcamera provides a unified and standardized interface for interacting with different types of camera devices. By integrating libcamera into pipewire, camera applications can use a single API to access and control camera hardware.
Flexibility and modularity: Pipewire is designed to be a modular multimedia framework.
Improved performance: Libcamera is designed to provide better performance and lower latency than previous camera APIs for Linux-based systems.
Cross-platform compatibility: Both libcamera and pipewire are open-source projects that can run on a variety of Linux-based platforms.
Integrating libcamera into pipewire helps to simplify and streamline the process of working with camera devices on Linux-based systems.

Enabled V4l2 driver in part of RPI-0 to capture data from /dev/video0 device.
Implemented soc level gstreamer pipeline with v4l2src plugin,omxh264enc plugin and appsink plugin.
V4l2src plugin is used to capture raw data from camera through v4l2 driver and transmitted captured raw data into omxh264enc plugin to encode raw data into h264 encoding format.After that transmitted encoded data into appsink plugin to wrote encoded data into 8080 port of mongoose server.
Registered 8080 port in Mongoose server to listen data.
Supported resolution SD( 640*480 , 720*576 ) ,HD( 1280*720 ) and Full HD( 1920*1080 )

Implemented RMS side gstreamer pipeline with souphttpsrc plugin and appsink plugin.
Souphttpsrc plugin is getting the encoded data from Mongoose server from 8080 port and transmitted encoded data into appsink plugin to feed the data into RMS.
Supported ASCLI interface to configure pull stream property and to start webrtc to transmit data into RRS server through WiFi.
Browser getting the data from RRS server and it display the received content.
