Instances

When a licence for the DRMan anti-piracy tool is being granted to a Widevine client, the Widevine licence server has the opportunity to provide the following rules that will be applied for the entirety of the material playback using the rules that were described earlier in the sentence. These rules will utilise the rules that were described earlier in the sentence.

The period of time during which a licence can be used lawfully and not be subject to any fines or other repercussions. The question “How long are you allowed to play material with the licence?” requires an answer. This is because it is a concern that must be addressed. (free time to occupy oneself and have fun) The following examples, which are all suitable instances of the same overarching premise, are presented below.

The period of time that the licence is still valid after the material has been played for the very first time after it has been re-played for the second time after it has been played for the third time after it has been played for the fourth time (when the licence was first used). This function is not available online and must be used either offline or through the process of renewing a licence in order to be utilised. Unfortunately, there is no other way to access this function.

Rent The amount of time that must pass before you are able to start playing the item is referred to as its “duration,” and it is denoted by the word “duration.” The only circumstances in which this might be useful are those in which it takes place in a location that is not connected to the internet.

Because of the variety of licencing choices available, it is now feasible to put a wide variety of scenarios into effect, including the following:

A straightforward illustration of a video stream

It is possible to adjust the “License Duration,” which affects how long a video can be played back after it has been streamed, to a specific period of time. This can be done by selecting the appropriate amount of time from the drop-down menu. Adjusting the “License Duration” parameter located inside the video’s attributes will allow you to accomplish this goal. To accomplish this, first select the “License Duration” option from the drop-down menu, then click the “Settings” button that is situated directly to the right of that option.

For instance, if you have a licence that is good for 180 minutes, you will have the opportunity to view content that spans a period of time that is equivalent to three hours’ worth of time.

Getting a new driver’s licence or having the one you already have renewed are also options. Developers who want to get their keys by sending a POST request to a URL with all of the headers and the body of the request included have two other alternatives accessible to them. These other possibilities can be found in the following sentence. Both of these alternatives entail directing the request to a certain location. In addition to that, the licenseHeaders object can be used in the case that it is necessary to do so in order to fulfil the requirements.

When it comes to acquiring a key, you have several options from which to pick, including the message buffer, the destination URI, and the getKey function. Each of these options offers something unique. Following is a breakdown of each of these available choices. After it has been processed, the callback that was utilised will then return the licence key that was requested.

You will have the ability to routinely renew your licence while you are streaming video if the feature that is known as License Renewal is enabled on your device. You can make use of this functionality if you so choose. This is necessary in order to enable live (linear) content or limit replays. Changing the value of ‘Renewal Delay’ to a shorter interval and then giving ‘Playback Time’ as the total playable time will compel the licence renewal to be performed at that interval. This can be done by clicking on the gear icon next to ‘Renewal Delay’ and selecting the appropriate value. Following the completion of the modification, this will become active immediately. This is something that will always be the case, regardless of whether or not the value is changed. Developers who want to get their keys by sending a POST request to a URL with all of the headers and the body of the request included have two other alternatives accessible to them. These other possibilities can be found in the following sentence. Both of these alternatives entail directing the request to a certain location. In addition to that, the licenseHeaders object can be used in the case that it is necessary to do so in order to fulfil the requirements.
