The following sections describe supported input types and codecs for live streaming content.

## Supported input types


Use the following input types to push streams from an external source or encoder (such as AWS Elemental MediaLive) using the HTTPS protocol:
+ HLS
+ CMAF

  For information about CMAF ingest, see [CMAF ingest](cmaf-ingest.md).

The following are additional input requirements:
+ You must define a channel policy to enable content to flow into your channel from sources outside of your account.
+ Media segments must not be encrypted.
+ Streams can contain either muxed video and audio tracks, or unmuxed tracks. 
+ The input must contain at least one video track. MediaPackage doesn't support inputs that contain no video track.

## Supported input codecs


These are the video, audio, and subtitles codecs that MediaPackage supports for source content streams.

## Supported output codecs


These are the video, audio, and subtitles codecs that MediaPackage supports when delivering live content.

**Note**  
The AV1 video codec is supported only with CMAF endpoint types. If you configure a TS endpoint on a channel with AV1 streams those streams won't show up on the endpoint.
