Do Teradek encoders work with third party decoders?

Overview

Teradek Encoders may work with third party software or hardware encoders, full compatibility is guaranteed when used with a Teradek Encoder.

There are hundreds of different parameters that can be used in H.264 encoding; some parameters are required while others are optional, and those optional settings should not present an issue for devices decoding the H.264 stream. 

However, actual implementations from third party hardware or software products can have variations at either the compression level or the transport (streaming protocol) level.

 

  • Streaming protocol: RTP/RTSP, MPEG-TS or SRT are the most common protocols used by devices receiving an IP video stream. These streaming protocols work over either TCP or UDP for the network protocol, except for SRT which only uses UDP.
  • Video compression: For 1st and 2nd generation Cube Encoders, 1st generation Slice Encoders and 1st generation T-RAX Encoders: H.264 at Level 4.1 / High Profile or lower (Main, Baseline), with a maximum resolution of 1920x1080 at 30 frames per second, and a bitrate of up to 10 Mbps. 3rd generation Cube Encoders and 2nd generation Slice Encoders can stream at up to 15 Mbps. 4th generation Cube Encoders / 3rd generation Slice Encoders and 2nd generation T-RAX Encoders can stream at up to 30 Mbps.
  • Audio compression: AAC-LC is the primary audio codec, but MPEG-1 Layer 2 is an optional codec when sending an MPEG Transport Stream.

 

Compatible Third Party Products

Below are some examples of third party encoders that are have been tested and confirmed working with Teradek Encoders.

Note that some devices have been reported as working by customers but have not been tested directly by Teradek.
