REST Interface

With version 2.0.0 of the DASH-IF Conformance Tool we offer a REST interface. Internally, the REST interface uses the Command Line Interface documented here. The basic syntax is as depicted below:

• http://localhost/Utils/Process_cli.php?url=[insert MPD url here]?[add modules as query parameters]

For instance, to run https://dash.akamaized.net/dash264/TestCases/1a/netflix/exMPD_BIP_TC1.mpd and enable the DASH-IF IOP module run:

• http://localhost/Utils/Process_cli.php?url=https://dash.akamaized.net/dash264/TestCases/1a/netflix/exMPD_BIP_TC1.mpd?iop=1

The list of available query parameters/modules corresponds to what is available in the command line interface:

• cmaf=1 : Enable CMAF checking
• ctawave=1: Enable CTA WAVE checking
• hbbtv=1: Enable HbbTV Checking
• dvb=1: Enable DVB checking (2018 xsd)
• dvb_2019=1: Enable DVB checking (2019 xsd)
• lowlatency=1 : Enable DASH-IF IOP Low Latency checking
• iop=1 : Enable DASH-IF IOP checking
• dolby=1 : Enable Dolby checking
• segments=1 : Enable Segment validation
• compact=1 : Provide compact JSON output
• latest_xsd=1: Use the latest xsd files for verification
• silent=1: Do not output JSON to stdout
• autodetect=1: Automatically detect profiles
• disable_detailed_segment_output=1: Disables the detailed segment validation output to reduce the size of the final JSON

The results are provided as a JSON output that looks the following:
