TVSDK requires specific properties for media content, manifest content, DRM, and software versions.
To use TVSDK, ensure that your hardware, operating system, and application versions all meet the minimum requirements listed below.
|Operating system||iOS 7.0 or later|
|Xcode||Xcode 10 for iOS 12 and Xcode 9 for iOS 11|
Check the restrictions and requirements for streams and playlists (manifests), including DRM encryption keys.
|Content segment key frames||Each content segment must begin with a key frame.|
|Sequence numbers in live/linear video||Must match between all bit-rate renditions for the main content at any given time.|
The version of
#EXT-X-VERSION in the .m3u8 manifest file affects which features are available to your application and which
EXT tags are valid.
Here is some information about the
#EXT-X-VERSION tag, which specifies the HLS protocol version:
The version must match the features and attributes in the HLS playlist; otherwise, playback errors might occur. For more information, see HTTP Live Streaming specification.
Adobe recommends using at least Version 2 of HLS for playback in TVSDK-based clients.
Clients and servers must implement the versions in the following way:
|Use at least this version||To use these features|
|EXT-X-VERSION:2||The IV attribute of the EXT-X-KEY tag.|
