Bitmovin Player SDKs provide several approaches to allow applications to intercept, manipulate and format HTTP requests and responses for Manifest, Media segments (audio/video/subtitle) and DRM licenses. This formatting is useful to enable well known use cases within the video workflow such as adding tokenization, formatting manifest files, formatting DRM license requests and responses, etc. Bitmovin player enables these use cases through two main APIs:
- NetworkConfig: Intended for general network manipulation use cases including Manifest, Media Segment and DRM license requests and responses.
- DrmConfig: Intended for DRM specific use cases.
The support of each API varies between different platforms so in the next sections we review the most common use cases for HTTP response/request manipulation and how they are supported by Bitmovin Player through each platform/SDK.
1. Adding custom data to Manifest/Media requests
Usually, players need to add custom data such as tokens for authentication, tracking, analytics, etc, prior to sending their requests to the CDN. To achieve this, typically the application requests for a token or generate any other custom data that lately is added to either the manifest or the segments requested. Usually the custom data or the token is appended to the request as:
A query parameter to HTTP URLs or
A Custom HTTP header
Bitmovin SDKs provide the
NetworkConfig.preprocessHttpRequest API to allow applications to intercept and manipulate HTTP requests for Manifest and Media segments - audio, video and subtitles, that will be sent by the player.
2. Formatting Manifest/Media files
Sometimes manifest files or the media segments in the customer's ecosystem don’t fully meet the specs and may have some properties not fully compatible with Bitmovin player. In such cases, it could be useful to intercept and modify the manifest on the fly - in order to parse the data properly, before it is processed by the player.
Bitmovin SDKs provide the
NetworkConfig.preprocessHttpResponse API to allow applications to intercept and manipulate HTTP responses for Manifest and Media segments - audio, video and subtitles.
3. Formatting DRM request/responses
Nearly every DRM license provider does have customized DRM workflows in place. This requires a custom formatting for either the DRM license requests and responses. Usually, the required DRM formatting implies:
Customizing HTTP headers for DRM requests
Formatting the payload data for DRM requests/responses
Bitmovin SDKs provides two ways to fully cover the previously mentioned use cases:
NetworkConfigAPIs: It is possible to format the DRM request and response using the general Network APIs
DrmConfigAPIs: As formatting DRM license requests and responses is a common practice, Bitmovin SDKs also provide a straightforward way to handle this directly through the
DrmConfigAPI. The API allows to set HTTP headers, prepare the payload for message license request, parse the payload on the license response, etc.
