PLAY rtsp://10.82.24.140/wfd1.0/streamid=0 RTSP/1.0
CSeq: j+2 Session: 6B8B4567
Output equipment starts the port transmission data to consulting after receiving request.
It is more than a whole set of flow process realizing equipment negotiation and transfer of data.To package, we have formulated the rule that some must be observed: video or audio frequency must first be transmitted by RTP mode with after the encapsulation of MPEG2-TS form, input equipment and output equipment all must support that MPEG2-TS comprises a road video and a road audio frequency, or only have video, or only has audio frequency.Such as use the data transmission pipe structure of Gstreamer framework realization as shown in Figure 3.
Four Long-distance Control implementations
Long-distance Control refers to that input equipment sends control information to output equipment, and after output equipment response limiting information, screen is corresponding changes, and now on-screen data outputs to input equipment, so just reaches the effect of input device controls output equipment.
After input equipment collects the information such as mouse, keyboard, touch screen, be sent to output equipment by RTSP bag, such as:
INPUT_CONTROL rtsp://localhost/wfd1.0 RTSP/1.0
CSeq: i+1 Content-Type: text/parameters
Mouse: CLICK,194,170
In sum, using the inventive method to realize Screen sharing can be cross-platform, and mode connected to the network has nothing to do, and can realize the Screen sharing between various smart machine.Through practical proof, for the image quality of 720p, the effect of Screen sharing can reach and postpone 500ms, and frame per second about 25, is better than the most of product on current market.The inventive method application scenarios is extensive, based on the extensible a series of application of this Screen sharing technology, and can realize the Long-distance Control of smart machine.
