In this process, cloud device such as also needs to video flowing is decrypted, decompresses, decodes at the operation.
In step S34, cloud device selected from multi-path video stream all the way video flowing as live TV stream.
In the disclosed embodiments, because cloud device can receive multi-path video stream simultaneously, so cloud device is needed
Select to carry out forwarding push as live TV stream all the way, it is ensured that spectators can normally watch live.
Wherein, step S34 can have various ways：
First way, the video flowing of predetermined number is selected as live according to the numbering of the multi-path video stream received
Stream.Predetermined number can be determined in the following way：Predetermined number list is obtained, is chosen in sequence in predetermined number list
Numbering is used as predetermined number.Wherein, selection refers in sequence, in selection predetermined number list after current live TV stream numbering
A video flowing numbering, and currently for for the first time selection numbering when, then selection predetermined number list in first video
The numbering of stream.That is, step S34 both can be for the first time selection video flowing exported as live TV stream or
Live TV stream is switched over.
Such as cloud device can receive the 5 road video flowings that numbering is 1-5, predetermined number list can for 1,4,3,2,
5, now, the video flowing that it is 1 that cloud device, which can select to number, is as live TV stream.
Wherein, the numbering of video flowing can be set by terminal device, and now terminal device is taken in transmitting video-frequency flow
