I can't disagree with you. The only use case comes into my mind is: If I want to create an audio authoring app, what I will do is a. Create several audio streams as source b. Connect these source in AudioContext, and append some filter c. mix and generate a output media stream, and put it into a media recorder d. Since I am creating an authoring app, suppose I should be able to select an encoding format that I want.

On mobile device, CPU is not as power as x86 system.

That's what we already did, isn't it? mozCamera is not connectable with all the other Web specs, such as webaudio/ media stream capture/ media source/ media recorder, I think this is the main reason we should not stick with it in long term. > > > > > -Shelly > _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
