ApsaraVideo Live does not limit the bitrate of ingested streams, and supports common resolutions and bitrates.

You can use the following common resolutions and bitrates :
  • 640 × 480: 100‒800 Kbit/s
  • 1280 × 720: 200‒1,500 Kbit/s
  • 1920 × 1080: 500‒4,000 Kbit/s
  • 2K (2560 × 1440): 2,000‒8,000 Kbit/s
  • 4K (3840 × 2160): 4,000‒30,000 Kbit/s
To prevent stuttering during stream ingest, we recommend that you take note of the following limits:
  • Use a bitrate that is not greater than 4 Mbit/s.

    You can determine whether to accept the recommendation based on the bandwidth of your stream ingest client. ApsaraVideo Live does not limit the bitrate.

  • Assume that 4K or 8K live streaming is implemented and the bitrate of ingested streams exceeds 25 Mbit/s.

    If the maximum size of a TS fragment exceeds 100 MB, live streams cannot be recorded.
