## Example usage

All mainstream DekTec Applications require a license and is exclusively developed for use on Microsoft Windows. A license can be purchased from DekTec or one of its distributors. There are also free utilities, such as `DtInfoCL` which can be installed with dektec-utilitiesAUR.

### Linux SDK solution

Linux SDK – SDK for DTA, DTU and DTE products provides developers with a driver and an API for using DekTec's DVB/MPEG-2 PCI/PCIe and USB-2 devices in applications running under Linux. All drivers are free to use except for DTAPITS and DtapiService.bin (self-extracting binary installer for DtapiService) which requires a license.

### SDK Examples

Install the dektec-avfifo-examplesAUR package.

AvFifo code examples for Linux, demonstrating the usage of the AvFifo API for receiving and transmitting SMPTE 2110 streams.

### External toolkits

Using TSDuck the MPEG Transport Stream Toolkit. TSDuck can be installed with tsduckAUR or tsduck-binAUR. It is an extensible toolkit for MPEG transport streams and can be used in digital television systems for test, monitoring, integration, debug, lab, demo. With this tool, the development possibilities are essentially endless.

## FFmpeg Integration

Install the ffmpeg-dektecAUR package.

Unlock the power of FFmpeg for real-time streaming of SDI or SMPTE 2110 via DekTec devices. DekTec device support to the `ffmpeg-dektec` and `ffplay-dektec` command-line utilities, the FFmpeg libraries for custom application development and the new `.sdi` file format for storage of raw SDI streams has been introduced since September 2023.
