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.
