Specific embodiment
Below in conjunction with drawings and examples, specific embodiments of the present invention will be described in further detail.Following reality
Example is applied for illustrating the present invention, but is not intended to limit the scope of the invention.
Video according to an embodiment of the present invention, which is specifically described, in conjunction with attached drawing first below decodes playback method 100.
As shown in Figure 1, video according to an embodiment of the present invention decode playback method 100, IE process and coding and decoding video into
Inter-Process Communication is carried out by intermediate module between journey, the method specifically includes:
The IE process accesses the intermediate module.
Broadcast information is sent to the coding and decoding video process by the intermediate module by the IE process.
The coding and decoding video process receives the broadcast information, and video is shown on window, and completion entirely played
Journey.
In other words, the IE process in video according to an embodiment of the present invention decoding playback method 100 and coding and decoding video into
Journey is two independent processes, can carry out Inter-Process Communication by intermediate module between two processes.That is, according to
The video decoding playback method 100 of the embodiment of the present invention is no longer limited by the resource bottleneck of browser, even if 64 bit manipulation of user
System uses 32 IE processes, can also configure one 64 coding and decoding video processes and go to take stream decoding display view
Frequently, the property of the monitoring system client of B/S framework no longer is greatly improved because 32 IE processes limit maximum broadcasting quantity
Energy.
Video according to an embodiment of the present invention decodes playback method 100 as a result, by separating the front and back end of video playing
It opens, so that decoding is played the resource occupation for being no longer limited by IE browser, more multi-channel video can be opened, improve browser broadcasting
Performance.
According to one embodiment of present invention, the IE process is by calling ocx plug-in unit to access the intermediate module.By
This, the technological means using ocx plug-in unit access intermediate module is mature, easy to use.
In certain specific embodiments of the invention, window handle and broadcast information are sent to by the IE process simultaneously
The coding and decoding video process.Preferably, it after the coding and decoding video process receives the broadcast information, carries out taking stream, decoding
And display, the video is shown on the window of corresponding window handle.
That is, video decoding playback method 100 according to an embodiment of the present invention provides one kind based on front and back end point
It is decoded from video and plays implementation, front and back end can separated, stream, decoding, playing module will be taken independent from IE process
Come, when opening simultaneously multi-path monitoring video, the memory of IE process will not occupy it is very high, no longer because IE process limit
Maximum plays quantity, greatly improves the performance of the monitoring system client of B/S framework.
Wherein it should be noted that the intermediate module in video according to an embodiment of the present invention decoding playback method 100 can
Think shared drive, IE process and coding and decoding video process are two independent processes, can be by altogether between two processes
The mode for enjoying memory carries out Inter-Process Communication.
As shown in Fig. 2, video according to an embodiment of the present invention decoding playing device 200 include: IE scheduler module 210, in
Between module 220 and coding and decoding video scheduler module 230.
Specifically, the IE scheduler module 210 can receive window handle and broadcast information, the intermediate module 220
It can be accessed by the IE scheduler module 210 and pass on the window handle and broadcast information, the coding and decoding video process mould
Block 230 receives the broadcast information that the intermediate module 220 is pass on, and video is shown on the window of corresponding window handle.
In other words, the IE scheduler module 210 and video in video decoding playing device 200 according to an embodiment of the present invention
Encoding and decoding scheduler module 230 is two independent scheduler modules, between two scheduler modules can by intermediate module 220 into
Row Inter-Process Communication.That is, video decoding playing device 200 according to an embodiment of the present invention is no longer limited by browser
Resource bottleneck can also configure one 64 videos and compile even if 64 bit manipulation system of user uses 32 IE processes
Decoding process goes that stream decoding display video is taken to greatly improve B/S frame no longer because 32 IE processes limit maximum broadcasting quantity
The performance of the monitoring system client of structure.
Video according to an embodiment of the present invention decodes playing device 200 as a result, by separating the front and back end of video playing
It opens, so that decoding is played the resource occupation for being no longer limited by IE browser, more multi-channel video can be opened, improve browser broadcasting
Performance.
According to one embodiment of present invention, the IE scheduler module 210 is by calling ocx plug-in unit to access the intermediate die
Block 220.Technological means as a result, using ocx plug-in unit access intermediate module 220 is mature, easy to use.
Wherein it should be noted that video according to an embodiment of the present invention decodes the intermediate module 220 in playing device 200
It can be shared drive, IE scheduler module 210 and coding and decoding video scheduler module 230 are two independent scheduler modules,
Inter-Process Communication can be carried out between two scheduler modules by way of shared drive.
To sum up, video decoding playing device 200 according to an embodiment of the present invention provides one kind based on front and back end point
It is decoded from video and plays implementation, front and back end can separated, stream, decoding, playing module will be taken independent from IE process
Come, when opening simultaneously multi-path monitoring video, the memory of IE process will not occupy it is very high, no longer because IE process limit
Maximum plays quantity, greatly improves the performance of the monitoring system client of B/S framework.
