TVSDK requires specific properties for media content, manifest content, and software versions.
System and software requirements
To use TVSDK, ensure that your hardware, operating system, and application versions all meet the minimum requirements listed below.
Operating system: iOS 6.0 or later
Content and manifest requirements
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 file affects what features are available to your application and what EXT tags are valid in your playlist/manifest.
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 .
- If the tag is not included in the master or media playlists, or if no version is specified, version 1 is used by default. Content that does not comply with version 1 will not play.
- Adobe recommends using at least version 2 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.|
