URL Custom Marquee
Backend Settings
Live streaming backend --> Select channel --> Content Protection (Anti-Screen Recording) Marquee --> In the marquee type, click to select "URL Custom Settings", then fill in the URL. For example: http://www.mywebsite.com/pmd.php
Player Parameter Retrieval
The player will append various parameters when requesting the JSON URL. http://www.mywebsite.com/pmd.php?vid=106385&uid=edvf2fpec9&code=aa&t=149008564655235879
Here, code=aa means aa is the value set for the code parameter (to ensure browser compatibility, if using Chinese, please base64 safe encode the value of code before sending).
Backend JSON Response
pmd.php Dynamic JSON Generation Reference
Note:
If the API returns Chinese content, please set the encoding to UTF-8.
The API response must include the Content-type header.

Sign Calculation Rule Parameters
Concatenate the values of the following parameters into a string and perform MD5 calculation. The signature requires all the following parameters to be concatenated, even if a value is not set.
$str="vid=".$vid."&uid=".$uid."&username=".$username."&code=".$code."&t=".$t."&msg=".$msg."&fontSize=".$fontSize."&fontColor=".$fontColor."&speed=".$speed."&filter=".$filter."&setting=".$setting."&alpha=".$alpha."&filterAlpha=".$filterAlpha."&filterColor=".$filterColor."&blurX=".$blurX."&blurY=".$blurY."&interval=".$interval."&lifeTime=".$lifeTime."&tweenTime=".$tweenTime."&strength=".$strength."&show=".$show;
$sign=md5($str);
Cross-Origin
crossdomain.xml
A crossdomain.xml file must be placed under the domain where the JSON URL is saved for Flash.
<cross-domain-policy>
<allow-access-from domain="*"/>
</cross-domain-policy>
Access-Control-Allow-Origin
The H5 player has cross-origin issues. This can be resolved by adding the following configuration in PHP.
