Description

Catalog ‣ PLUGINS ‣ SiMa Plugins ‣ software_plugins ‣ simaaisrc

GStreamer plugin reference: simaaisrc

This is a plugin which supports memory allocation on the SiMa device (compute blocks namely A65, EV74, and the MLA). It reads file(s) from the file system and puts it into the device memory for other plugins (like process-cvu) to read. Due to memory allocation support, this plugin is useful in debugging during pipeline development.

This plugin also reads the source file and pushes it into the pipeline. It is commonly used for playing video/audio files, processing images, or handling raw data streams.
