Info

GStreamer Overview• Capabilities: describes input/output data• Example: “video/x-raw-gray, bpp=16, depth=16,endianness=BIG_ENDIAN, width=640, height=480”• video/x-raw-rgb, video/x-raw-bayer, image/tiff, audio/x-raw-int, etc.• Properties• Communication• Buffers – sample of audio, frame of video• Events/Messages/Queries – communication between elements and/or application
GStreamer Strengths• Modularized processing• Can combine elements in arbitrary ways for rapid prototyping• Already developed data processing steps aid in rapid development• Single stream of data can be displayed, written to file, processedmultiple times, or any combination of them.• Quick testing of pipeline through command line• Automatic negotiation of capabilities• Handles time synchronization• Automatic plug-in discovery• Agnostic to data type• Arbitrary capabilities
