In RTSP, media streams are routed between server and clients by using RTP packets. In order to decode a stream, RTP packets must be converted into codec-specific frames. This conversion happens by following a RTP payload format. This library provides encoders and decoders for the following formats:

• RFC2326, RTSP 1.0
• RFC7826, RTSP 2.0
• RFC8866, SDP: Session Description Protocol
• RFC3551, RTP Profile for Audio and Video Conferences with Minimal Control
• RFC2250, RTP Payload Format for MPEG1/MPEG2 Video
• RFC2435, RTP Payload Format for JPEG-compressed Video
• RFC6416, RTP Payload Format for MPEG-4 Audio/Visual Streams
• RFC6184, RTP Payload Format for H.264 Video
• RFC7798, RTP Payload Format for High Efficiency Video Coding (HEVC)
• RFC7741, RTP Payload Format for VP8 Video
• RTP Payload Format for VP9 Video
• RFC3190, RTP Payload Format for 12-bit DAT Audio and 20- and 24-bit Linear Sampled Audio
• RFC5215, RTP Payload Format for Vorbis Encoded Audio
• RFC7587, RTP Payload Format for the Opus Speech and Audio Codec
• RFC3640, RTP Payload Format for Transport of MPEG-4 Elementary Streams
• RTP Payload Format For AV1 (v1.0)
• Codec standards
• Golang project layout
