int TRTC_APP_SCENE_LIVE
final

In the interactive video live streaming scenario, mic can be turned on/off smoothly without waiting for switchover, and the anchor latency is as low as less than 300 ms. Live streaming to hundreds of thousands of concurrent audience users is supported with the playback latency down to 1,000 ms.
Use cases: `low-latency video live streaming`, `interactive classroom for up to 100,000 participants`, `live video competition`, `video dating room`, `remote training`, `large-scale conferencing`, etc.
Note: in this scenario, you must use the `role` field in `TRTCParams` to specify the role of the current user.
