Android At present, there is no similar playing method and ecosystem on the platform , I wonder if it will be updated later . However, it does not hinder the experience that third-party companies will launch similar playing methods and cross platform solutions , but SharePlay Taking advantage of Apple's unique permissions , Third party implementations may be difficult to achieve a similar cross platform experience .

At present, we can see that there are more and more products in the direction of experience sharing , such as K Song experience sharing ： Offline K Songs can be sung with friends , Hear your friends sing in time , Under the blessing of ultra-low delay , on-line K The song can connect wheat , Get a chorus experience without perceptual delay .

WebRTC To achieve SVC 了

Actually WebRTC I've supported it for a long time vp9 Of SVC, But it can only be started from the command line , It cannot be opened by default . later SVC Become WebRTC 1.0 API Extended specification , Now complete SVC Support .SVC It is very useful in video conference scenes , But it also brings a lot of problems , For example, the mobile terminal is turned on SVC after , You may have to give up hardware coding , A beautiful technology will always bring a lot of regrets and trade-offs when it comes to real implementation .

Consulted Intel to Chrome After being an expert in hardware codec support , Understand that this time SVC The implementation of is not so perfect ：

“ It's for av1 With vp9 Still ignore this api 264 Will only support L1T2 and L1T3. However av1 I'm only in windows Plus support , And will only support L1T2 and L1T3. Unless you only use software coding ”
