Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The method that realizes the stream medium data transmission at portable terminal provided by the invention as shown in Figure 1, comprises the steps:
Wherein, the multi-medium data that gathers can comprise voice data, video data, text data, image data etc., wherein video data can pass through the camera Real-time Collection of portable terminal, and voice data can be by the microphone Real-time Collection of portable terminal.Certainly, voice data, video data, text data, image data etc. also can be from the storage devices of portable terminal this locality, as obtaining in the built-in internal memory of portable terminal or the storage card.
Coding can adopt existing any coded format, for example described video data encoding can be form H.264, and audio data coding is the AAC form.
Multi-medium data behind the coding can further be encapsulated as Streaming Media section file, for example the video data of described H.264 form and the voice data of described AAC form is encapsulated as the MPEG-2TS format stream, and becomes Streaming Media section file by 5 seconds for unit.Unit and the stream format specifically cut apart are any, can decide according to concrete needs.
Be divided into after the Streaming Media section file, also need to carry out index, the form of concrete index file is any, for example the m3u8 form.In addition, index file can dynamically update in the live process, and is smooth continuously to guarantee audio frequency and video.
Make the same prior art of mode of the streaming media on demand page, repeat no more here, in addition, the preferred HTML 5(HTML5 that adopts among the present invention) make, and by video tab＜video identify described index file and described files in stream media.Adopt HTML5 to make the streaming media on demand page, destination mobile terminal need not to install Streaming Media client soft software, only needs to support that the web browser of HTML5 gets final product.
Wherein, described web service can be IIS of the APACHE of Apache, NGINX or Microsoft etc.; The preferred APACHE that uses among the present invention, APACHE is a kind of webpage of increasing income (Web) server software, it can be used as web services, operate on nearly all widely used PC system platform, such as windows, linux etc., versatility is widely used well, but APACHE does not also have the precedent of use on mobile-terminal platform at present, Android (android) system for example, the present invention is transplanted to APACHE in the system of portable terminal.But, for easy to use, need to allow APACHE start voluntarily with the startup of portable terminal, and support streaming media service, so also need to be handled as follows:
APACHE is configured, comprises: the newly-increased statement of opening described APACHE service in mobile terminal system start script;
In the configuration file of described APACHE service, add the support statement to described index file type and described Streaming Media section file format.
Particularly, for the portable terminal that uses Android (Android) operating system, the apache that increases income under the transplanting Linux will solve the allocation problem of apache under android under Android, make its start just can automatically open on the backstage operation.
Solution can be (because init.rc generally is stored among the read-only file district ramdisk of portable terminal at Android start script init.rc so, can't revise, so during practical operation, the present invention is chosen in the sub-script that init.rc comprises, such as/etc/init.qcom.sh, these scripts are positioned at/the etc/ catalogue, can be by the attribute modification order, for example read only attribute is revised in the remount order, reach the purpose that it can be modified) in, (httpd is the main program of Apache in newly-increased unlatching httpd service, be designed to the background process of an independent operating, it can be set up one and process the subprocess of request or the pond of thread) statement.
If add statement in * .rc, concrete statement is as follows:
service?httpd/system/bin/httpd–f/data/local/apache/conf/httpd.conf
user?system
oneshot
If add statement in * .sh, concrete statement is as follows:
httpd/system/bin/httpd–f/data/local/apache/conf/httpd.conf
For the configuration file httpd.conf of apache, except general configuration, for solving apache for the support of Streaming Media section file and index file among the present invention, key also need to add following statement in configuration file:
AddType application/x-mpegURL.m3u8 (adding the index file support to the m3u8 form)
AddType video/MP2T.ts (adding the Streaming Media section file support to the ts form).
Pass through above-mentioned steps, portable terminal has had as the ability that sends stream medium data in the streaming media as server end to other destination mobile terminal, can be used as a streaming media server, provide the Streaming Media section multimedia data stream that file forms to other destination mobile terminal.At this moment, as long as portable terminal starts the WIFI hotspot service, set up wireless connections by described WIFI hotspot service and other destination mobile terminal; According to the access of described destination mobile terminal to the described streaming media playing page, just can send described Streaming Media section file to described destination mobile terminal by described wireless connections.The form of Media Stream can adopt the HTTP Live Streaming of apple (APPLE) company, and this form is supported that by HTML5 preferably versatility is arranged.
Said method can allow portable terminal become a streaming media server, the multi-medium data of portable terminal from camera and microphone Real-time Collection transmitted to other destination mobile terminal with the Streaming Media form, the realization of this function, make the user can use at any time mobile phone to the live video that photographed of other good friend, at any time live accident, report to the police or share what is seen and heard with the good friend, gather around and have broad application prospects.
In addition, in order to adapt to different screen resolutions, the portable terminal of different screen color figure place, make different portable terminals can both obtain the Streaming Media section file of appropriate size, reduce the transmission bandwidth waste, for example the screen resolution of destination mobile terminal only has 640x480, can only show 256 looks, yet the specification of the Streaming Media that portable terminal provides section file is 800x480 resolution, 16 looks, the display capabilities upper limit that has exceeded the destination mobile terminal screen, so much remaining data will be wasted, and transmit the waste that these redundant datas will cause transmission bandwidth.
In the cataloged procedure of step 102, can be the multiple different size of different resolution, different colours figure place with the video data encoding of Real-time Collection so;
In the encapsulation process of step 103, the video data of the video format of different size is encapsulated as the Streaming Media section file of different size;
In the Index process of step 104, will carry out respectively index to the Streaming Media section file of different size;
Generate in the process of the program request page in step 105 at last, on the described streaming media on demand page, the link of the Streaming Media section file of corresponding different size is set.
So during the destination mobile terminal access stream media-on-demand page, the Streaming Media section file that just can select to be fit to the specification of own onscreen display capability carries out program request, thereby reduces the waste of transmission bandwidth.
For example place the link of different size Streaming Media section file with the html grammer at the program request page, according to being labeled as from small to large " smoothness ", " SD ", " high definition " printed words, the user can click the specification that corresponding chain fetches streaming media switch section file according to own actual displayed ability.
In addition, the second solution is, the screen resolution of Real-time Obtaining destination mobile terminal and color figure place information, screen resolution and color figure place according to destination mobile terminal, come resolution and the color figure place of coding in the determining step 102, realization also can reduce the waste of transmission bandwidth to the self adaptation of the onscreen display capability of destination mobile terminal.
Particularly, can use at the program request page screen resolution and the color figure place information of JavaScript Code obtaining destination mobile terminal, the Streaming Media section file that needs what specification is judged in combination.
For example: if screen resolution is 800X480, then encoder can select close 720x480 size to make Streaming Media section file.
In addition, when the played in full screen demand is arranged, also may need to solve the problem of video played in full screen.
The played in full screen standard of HTML5 standard definition is element.requestFullscreen () and document.exitFullscreen ();
Yet the specific implementation of each browser and incomplete compatible HTML5 standard, such as Safari and Chrome browser, the method for use is: element.webkitRequestFullScreen () and document.webkitCancelFullScreen ();
Firefox then uses: element.mozRequestFullScreen () and document.mozCancelFullScreen ();
For the various main flow browsers of compatibility, can use the JavaScript code at the program request page:
Browser type=＜script〉document.write (navigator.appName)＜/script 〉
Browser version=＜script〉document.write (navigator.appVersion)＜/script 〉
Control system=＜script〉document.write (navigator.platform)＜/script 〉
AppCodeName=<script>document.write(navigator.appCodeName)</script>
According to these four information, combination judges that destination mobile terminal should take the full frame interface of what type.
For not supporting that full frame, full frame effect is bad, the browser of unknown title, as supporting by force played in full screen, then can take third-party played in full screen plug-in unit.
