FFmpeg Integration for DekTec Devices
Unlock the power of FFmpeg for real-time streaming of SDI or SMPTE 2110 via DekTec devices. We have added DekTec device support to the 'ffmpeg' and 'ffplay' command-line utilities, and to the FFmpeg libraries for custom application development.
Key Additions to FFmpeg
|ffmpeg||Added '-f dektec' for real-time SDI/2110 input/output via DekTec devices.|

FFmpeg Command-Line Examples
Explore these representative 'ffmpeg' command-line examples to get a feel for the extensive functionality of our FFmpeg integration. These examples are just the tip of the iceberg - the 'ffmpeg' tool provides countless command-line options. Furthermore, combining FFmpeg libraries with DekTec I/O opens up a world of possibilities for crafting your own bespoke applications.
The picture below, shows a configuration where the ffmpeg tool is used to stream a service, from a transport-stream file, as SMPTE-2110 video and audio streams via a DTA-2110 card.
ffmpeg -i input.ts -url:v 126.96.36.199:5678 -url:a 188.8.131.52:5680 -f dektec 2110000054
ffmpeg -i input.ts -f dektec 2178000132:4
To view/listen to video/audio received with a DekTec card you can use the ffplay tool. This is illustrated in the picture below, where ffplay is used to view the contents of a SDI signal received with a DTA-2172 card.
ffplay -f dektec -i 2172000209
ffplay -url:v 184.108.40.206:5678 -url:a 220.127.116.11:5680 -f dektec -i 2110000054
The example below combines the previous two examples into a SDI-to-SMPTE-2110 gateway. This time the ffmpeg tool is used to route the video and audio extracted from the SDI signal received with a DTA-2172 to a DTA-2110, which transmits them as ST 2110-20 and ST 2110-30 video and audio IP streams.
ffmpeg -f dektec -i 2172000209 -url:v 18.104.22.168:5678 -url:a 22.214.171.124:5680
-f dektec 2110000054
Supported DekTec Adapters
Below is a list of DekTec products that work well with our FFmpeg integration. Please note that while these have been checked for compatibility, results may vary based on your specific usage and configuration.
DTA-2110 – 10G Network Card Optimized for SMPTE 2110
The DTA-2110 is a high-performance PCIe card that enables receiving or transmitting of SMPTE ST 2110 audio and video streams into or out of FFmpeg. 'ffplay' allows you to view these streams directly in a window.
DTA-2172 – Dual 3G-SDI/ASI Ports for PCIe
Each of the two ports enables receiving or transmitting an SDI stream (SD, HD, or 3G) into or out of FFmpeg. With 'ffplay', you can view the SDI stream directly in a window.
DTA-2174B – Quad 3G-SDI/ASI Ports (1x12G) for PCIe
Each of the four ports enables receiving or transmitting an SDI stream (SD, HD, or 3G) into or out of FFmpeg. While the card supports 12G, this is currently not supported by our FFmpeg integration. For viewing purposes, 'ffplay' allows you to display the SDI stream directly in a window.
DTA-2178 – Eight 12G-SDI/ASI Ports for PCIe
Each of the eight ports enables receiving or transmitting an SDI stream (SD, HD, or 3G) into or out of FFmpeg. While the card supports 12G, this is currently not supported by our FFmpeg integration. For viewing purposes, 'ffplay' allows you to display the SDI stream directly in a window.
