Command Line Interface

The new version of the DASH-IF Conformance Tools offer a command-line interface that can directly be called via php. Note that because of relative paths linking to specific dependencies you need to call the command line interface from the Utils folder:

cd Utils
php Process_cli.php [options] <url> 

Possible options are:

• -h, --help : Print help text
• -c, --cmaf : Enable CMAF checking
• -w, --ctawave: Enable CTA WAVE checking
• -H, --hbtv: Enable HbbTV Checking
• -D, --dvb: Enable DVB checking (2018 xsd)
• --dvb_2019: Enable DVB checking (2019 xsd)
• -l, --lowlatency : Enable DASH-IF IOP Low Latency checking
• -i, --iop : Enable DASH-IF IOP checking
• -o, --dolby : Enable Dolby checking
• -s, --segments : Enable Segment validation
• -C, --compact : Provide compact JSON output
• --latest_xsd: Use the latest xsd files for verification
• -S, --silent: Do not output JSON to stdout
• -A, --autodetect: Automatically detect profiles
• --disable_detailed_segment_output: 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:
