>> Hi everybody
>> We're having needs for a streaming_video-capable wl_surface. An extended
>> surface that could "queue buffers up" along with presentation timestamps in
>> the compositor so that videosink clients (like gstreamer's wayland
>> videosink) could more effectively and precisely synchronize audio and video
>> on specific time cues.
>> I'd like your comments/opinion about this first draft of the protocol.
>> Protocol and interfaces names, language, set of requests, etc...
>> The idea for now is to let the clients queue buffers in advance and clear
>> the queue abruptely for cases where they'd need, e.g. to "pause" the
>> streaming.We're still having a whole bunch of implementation-wise
>> questions, but that's a start. It'd be awesome if I had your feedback on
>> this protocol.
>> Thanks !
