Bug report

Describe the bug

The header values are encoded in base64. Inputstream adds the custom headers, but special characters just like "=" or "+" are getting removed automatically.

Expected Behavior

The original base64-encoded strings are used to send the authorization headers to the license server => HTTP 200.

Actual Behavior

The behavior mentioned above results in invalid base64 strings being rejected by the license server. HTTP 400

Possible Fix

Please add an option to add the original header values instead.

To Reproduce

Steps to reproduce the behavior - please find my code below:

license_url = "https://licf-iptv.dmm.t-online.de/v1.0/WidevineLicenseAcquisition.ashx"
            
lapb = '<lapb version="2"><contentNo>' + c_no + '</contentNo><profile>sl-windows</profile><auth type="sts">' + session["access_token"] + '</auth><agent>WEB-MTV</agent><recovery allow="false"/><requestId>' + str(uuid4()) + '</requestId><serviceId>MAGENTATVAPP</serviceId></lapb>'            
lapb_encoded = b64encode(lapb.encode()).decode()

device_id = session["deviceId"]
device_id_encoded = b64encode(device_id.encode()).decode()

li.setProperty('inputstream.adaptive.license_key', license_url + "|" + f'CustomDeviceId={device_id_encoded}&LAPB={lapb_encoded}' + "|R{SSM}|")
li.setProperty('inputstream.adaptive.license_type', "com.widevine.alpha")

li.setProperty('inputstream', 'inputstream.adaptive')
li.setProperty('inputstream.adaptive.manifest_type', 'mpd')
li.setProperty("IsPlayable", "true")
