In DLNA, the agreement usually adopted is UPnP (Universal Plug and Play, UPnP) agreement, is connected with the peer-to-peer network realizing smart machine, wireless device spreads all over the world with PC etc.As shown in Figure 1, the network architecture of DLNA can comprise control point, playback equipment and DLNA server.Wherein, control point can for the equipment found and in net control, such as, mobile phone, panel computer etc. for DLNA can be provided to serve; Playback equipment can for computer, mobile phone and the intelligent television etc. supporting DLNA to operate; DLNA server provides service for control point and playback equipment, is shared by the media file on control point, so that playback equipment obtains the shared media file in control point from DLNA server and plays.
Apply the above-mentioned network architecture, the embodiment of the present invention provides a kind of player method of media file, as shown in Figure 2, comprising:
201, playback equipment receiving media file, media file comprises first kind field and Second Type field, and calls corresponding player according to first kind field.
Control point can adopt UPnP protocol and after being connected with playback equipment by DLNA server, control point just can be sent to DLNA server, so that playback equipment obtains this media file from DLNA server by needing the media file shared.Wherein this media file comprises the attribute information of media file, the title of such as media file, size, URL, and the information such as the file type of media file.This attribute information comprises first kind field, for calling corresponding player plays media file.Wherein, this media file is the file being applied to DLNA technology, is also DLNA file.
Careless omission during software development or software bug may cause some field errors in attribute information or loss, when playback equipment is when receiving this media file, the first kind field that media file carries can be confirmed: whether upnp:clas is legal, if legal, then call corresponding player; If illegal, then call player failure.Here legal refers to the value that media file carries first kind field, and the value of this first kind field is the normal value of industry standard.
If first kind field is legal, then playback equipment calls the player plays media file corresponding to first kind field.Also be, if carry the value of first kind field upnp:clas in playback equipment determination media file, just first kind field is resolved, the value of such as upnp:clas field is: object.item.videoItem, what represent control point propelling movement is video file, and the video player that playback equipment then calls for displaying video plays this video file; Or the value of upnp:clas field is: object.item.imageItem, what represent control point propelling movement is picture file, and the picture players that playback equipment then calls for playing pictures plays this picture file; Or the value of upnp:clas field is: object.item.audioItem, what represent controller propelling movement is audio file, and playback equipment then calls this audio file of audio player plays for audio plays.
202, when player malloc failure malloc, obtain the keyword in Second Type field, and according to keyword and preset keyword database update first kind field, wherein, keyword is the field of the file format of characterizing media file.
When not carrying in the media file that may cause due to software developer's horizontal problem or software bug or other reason that the value of the value of upnp:clas field or upnp:clas field is lack of standardization makes player malloc failure malloc, playback equipment can obtain the keyword in Second Type field, and upgrade first kind field according to field corresponding with this keyword in preset keyword database, also namely this keyword database comprises the corresponding relation of keyword in Second Type field and first kind field.Wherein, the keyword in Second Type field is the field of the file format of characterizing media file.Such as Second Type field is here DLNA DLNA parameter: protocol Info, protocol Info field comprises the detailed DLNA parameter of media file; Or Second Type field is the URL(uniform resource locator) (Uniform Resource Locator, URL) of media file.
Specifically, when Second Type field is protocol Info, the DLNA parameter that it comprises can be as shown in table 1 below.
Table 1
| http-get/rtsp-get | * | MIME-TYPE | DLNA.ORG_PN |
Wherein, http-get/rtsp-get represents the transmission means of media file between playback equipment and DLNA server, and http-get is the transmission means of industry standard, and rtsp-get is optional transmission means; The media formats of MIME-TYPE presentation medium file can be such as video/mp4, image/jpeg etc.; The concrete DLNA parameter that DLNA.ORG_PN presentation medium file is corresponding, such as DLNA.ORG_PN can be MPEG4_P2_MP4_SP_AAC, also can be JPEG_SM etc.MIME-TYPE field wherein and DLNA.ORG_PN field can both the file formats of characterizing media file.
Or Second Type field is URL, such as, can be:
http://192.168.2.101:58421/cd/getcontent/0/7/9_1.jpg。
In specific implementation process, keyword in above-mentioned acquisition Second Type field, and first kind field can comprise according to keyword and preset keyword database update: determine whether Second Type field comprises keyword, if comprise, then determine the keyword that whether there is Second Type field in preset keyword database, if exist, then according to field corresponding with the keyword in Second Type field in preset keyword database, upgrade described first kind field.
If Second Type field is protocol Info, in the first mode in the cards, first kind field can be determined by the corresponding relation of the first kind field in preset keyword database (key storehouse) and Second Type field, and the first kind field in step of updating 201, or before renewal first kind field, first determine whether protocol Info field comprises keyword, if comprise, then determine the keyword that whether there is protocol Info field in preset keyword database, if exist, then the field corresponding with the keyword of protocol Info field is defined as first kind field, although this is because media file comprises the value of protocol Info field, but the value of protocol Info field may be caused and lack of standardization due to software bug or other reason, if the value specification of protocol Info field, then determine to there is the field corresponding with the keyword of protocol Info field in preset keyword database.
If Second Type field is protocol Info, in the second mode in the cards, when protocol Info field comprises keyword, can by the keyword of protocol Info field and the corresponding relation of file type in preset keyword database, determine the keyword that whether there is protocol Info field in preset keyword database, if exist, then the file type corresponding with the keyword of protocolInfo field is defined as the file type of media file, and in preset keyword database, also there is the corresponding relation of file type and first kind field, then indirectly can determine the first kind field corresponding with the keyword of protocol Info field.
Concrete, with reference to table 1, because protocolInfo field comprises MIME-TYPE field and DLNA.ORG_PN field, MIME-TYPE field can the file format of presentation medium file, DLNA.ORG_PN field carries the concrete DLNA parameter of media file, also can comprise the file format of media file, therefore, the first kind field in media file properties information can be inferred by MIME-TYPE field or DLNA.ORG_PN field.Therefore, according to the first mode in the cards above-mentioned, if above-mentioned Second Type field is protocolInfo, describedly determine that the keyword that whether there is Second Type field in preset keyword database can comprise: determine in preset keyword database, whether to there is the field identical with the MIME-TYPE field in DLNA parameter or DLNA.ORG_PN field; Describedly upgrade described first kind field according to field corresponding with the field characterizing the file format of described media file in DLNA parameter in preset keyword database and can comprise: according in described preset keyword database with described MIME-TYPE field or field corresponding to described DLNA.ORG_PN field, upgrade described first kind field.
Exemplary, such as when MIME-TYPE field is video/mp4, can determine that the field corresponding with video/mp4 field is: object.item.videoItem according to first kind field and the corresponding relation of MIME-TYPE field, namely corresponding with the keyword of Second Type field first kind field is: object.item.videoItem; Or, when DLNA.ORG_PN field is JPEG_SM, can determine that the field corresponding with JPEG_SM field is: object.item.imageItem according to first kind field and the corresponding relation of DLNA.ORG_PN field, namely corresponding with the keyword of Second Type field first kind field is: object.item.imageItem.
According to above-mentioned the second mode in the cards, playback equipment determination preset keyword database comprise above-mentioned can the field of file format of characterizing media file, during the keyword of i.e. Second Type field, then according to the keyword of Second Type field in preset keyword database and the corresponding relation of file type, determine in preset keyword database, whether to there is the field identical with the MIME-TYPE field in Second Type field or DLNA.ORG_PN field, if exist, then determine to there is the file type corresponding with MIME-TYPE field or DLNA.ORG_PN field in preset keyword database, the file type that the keyword of Second Type field is corresponding is file type corresponding with MIME-TYPE field or DLNA.ORG_PN field in preset keyword database, again according to the corresponding relation of file type and first kind field, then indirectly can determine the first kind field corresponding with MIME-TYPE field or DLNA.ORG_PN field.
Exemplary, such as when MIME-TYPE field is video/mp4, can determine that the file type corresponding with video/mp4 field is video file according to MIME-TYPE field and the corresponding relation of file type, also the file type that namely keyword of Second Type field is corresponding is video file, because first kind field and file type also exist corresponding relation, therefore can be according to the corresponding relation determination first kind field of this file type of video file and first kind field: object.item.videoItem; Or, when DLNA.ORG_PN field is JPEG_SM, can determine that the file type corresponding with JPEG field is picture file according to JPEG field and the corresponding relation of file type, also the file type that namely keyword of Second Type field is corresponding is picture file, can be therefore object.item.imageItem according to the corresponding relation determination first kind field of this file type of picture file and first kind field; Again such as when DLNA.ORG_PN field is MPEG4_P2_MP4_SP_AAC, can determine that the file type corresponding with MP4 field is video file according to MP4 field and the corresponding relation of file type, also the file type that namely keyword of Second Type field is corresponding is video file, therefore can be according to the corresponding relation determination first kind field of this file type of video file and first kind field: object.item.videoItem.
If Second Type field is the URL of media file, then namely can upgrade first kind field for the field of the file format of characterizing media file and the corresponding relation of first kind field according to the keyword in URL.Or, first determine the field that whether there is the file format for characterizing media file in URL, if exist, determine the field whether existed in preset keyword database for the file format of characterizing media file in URL again, if exist, then upgrade first kind field according in preset keyword database with URL for the field that the field of the file format of characterizing media file is corresponding.
Exemplary, if the URL of media file is:
Http: // 192.168.2.101:58421/cd/getcontent/0/7/9_1.jpg, be jpg for the field of the file format of characterizing media file in URL, also jpg field is included in database, and jpg field is corresponding with object.item.imageItem, then first kind field is updated to object.item.imageItem.
203, playback equipment calls corresponding player according to the first kind field after renewal, and plays media file.
Make player malloc failure malloc first kind field is illegal like this, thus when needing to infer first kind field according to Second Type field, can after according to Second Type field and preset keyword database update first kind field, call corresponding player plays media file according to the first kind field in media file after upgrading.First kind field such as, after upgrading in media file is object.item.videoItem, then call video player and play media file.
The embodiment of the present invention provides a kind of player method of media file, receiving media file, media file comprises first kind field and Second Type field, and call corresponding player according to first kind field, when player malloc failure malloc, obtain the keyword in Second Type field, and according to keyword and preset keyword database update first kind field, wherein, keyword is the field of the file format of characterizing media file, corresponding player is called according to the first kind field after upgrading, and play media file, like this, when player malloc failure malloc, can can the corresponding relation of the field of file format of characterizing media file and first kind field be counter releases first kind field according to what carry in media file in preset keyword database, and then call corresponding player plays media file according to first kind field, if call player failure just refusal broadcasting media file compared to media file in prior art according to first kind field, the application can solve media file may occur that when pushing playback equipment can this media file compatible, but the problem play is refused due to can not player be called.
Because the form of URL is comparatively complicated, the form of the URL generated is varied, lack fixing URL specification or other reason, may exist can not according to the first kind field of URL deduction for calling player, such as, not comprising in URL can the field of file format of characterizing media file, make the probability that there is not the field identical with the field in URL in preset keyword database relatively large, therefore, the accuracy of the first kind field determined according to DLNA parameter is higher than the accuracy of the first kind field determined according to URL.Therefore, preferably, above-mentionedly determine whether Second Type field comprises keyword and can be: the field first determining whether to exist in DLNA parameter and preset keyword database the file format for characterizing media file, this be due to the reasons such as software developer's horizontal problem or software bug also likely cause in DLNA parameter for the file format of characterizing media file field lose or lack of standardization, if like this DLNA parameter do not comprise or due in DLNA parameter for the field of the file format of the characterizing media file keyword causing not existing in preset keyword database this Second Type field lack of standardization, then determine whether to comprise keyword according to URL again, therefore, as shown in Figure 3, further embodiment of this invention provides a kind of player method of media file, comprise:
301, playback equipment receiving media file, and determine that whether the first kind field of media file is legal, first kind field is used for calling corresponding player plays media file, if legal, then plays media file; If illegal, then perform step 302.
302, the field of the file format whether comprising characterizing media file in DLNA parameter determined by playback equipment, if comprise, then performs step 303; If do not comprise, then perform step 305.
303, whether there is the field of the file format of characterizing media file in DLNA parameter in playback equipment determination preset keyword database, if exist, then perform step 304, if do not exist, then perform step 305.
304, playback equipment upgrades first kind field according to field corresponding with the field of the file format of characterizing media file in DLNA parameter in preset keyword database, then performs step 308.
Whether comprise the field of the file format of characterizing media file in the URL of 305, playback equipment determination media file, if comprise, then perform step 306, if do not comprise, then perform step 309.
Because media file also can carry the uniform resource position mark URL of this media file in its media file when pushing, the field of the file format of presentation medium file may be carried in this URL, therefore, when DLNA parameter does not comprise the field of the file format of characterizing media file, or due to the field contents of the file format of characterizing media file (illegal) lack of standardization in DLNA parameter make the field of the file format that there is not characterizing media file in DLNA parameter in database time, also can be inferred the content of first kind field by the URL of media file.Like this, can find whether there is the field identical with the field in the URL of media file to determine first kind field from the database preset.
306, whether there is the field of the file format of characterizing media file in URL in playback equipment determination preset keyword database, if exist, then perform step 307, if do not exist, then perform step 309.
Here it can be that the form of URL owing to generating is varied that database not to exist in URL for the field of the file format of characterizing media file, the field not conforming to specification may be there is, make the field do not existed in database for the file format of characterizing media file in URL.
307, playback equipment upgrades first kind field according to field corresponding with the field of the file format of characterizing media file in URL in preset keyword database.
For example, the URL of media file is:
Http: // 192.168.2.101:58421/cd/getcontent/0/7/9_1.jpg, according to the first mode in the cards above-mentioned, the corresponding relation of jpg field and object.item.imageItem field is preserved in preset keyword database, therefore, can determine to there is the field jpg identical with the field in the URL of media file in preset keyword database, the field that this jpg is corresponding is object.item.imageItem, then determine that the field object.item.imageItem corresponding with jpg is first kind field, so that playback equipment just can call this picture file of picture player plays according to the first kind field in the media file after renewal.
According to above-mentioned the second mode in the cards, jpg field is preserved and file type is the corresponding relation of picture file in preset keyword database, therefore, can determine to there is the field jpg identical with the field in the URL of media file in preset keyword database, file type corresponding to this jpg field is picture file, this file type of picture file is again that object.item.imageItem exists corresponding relation with first kind field, therefore, the file type corresponding according to jpg field can determine that first kind field is object.item.imageItem, so that playback equipment calls this picture file of picture player plays according to the first kind field in the media file after renewal.
308, playback equipment calls corresponding player according to the first kind field after renewal, and plays media file.
309, playback equipment refusal plays media file, and display reminding information is with reminding user.
If URL does not exist for there is not the field identical with the field in the URL of media file in the field of the file format of characterizing media file or database, playback equipment cannot infer first kind field, also corresponding player plays media file cannot just be called, playback equipment is just refused to play this media file, display alarm information can cannot play with this media file of reminding user in the display of playback equipment side, cannot can certainly be play by this media file of DLNA server notice control point.
Therefore, the embodiment of the present invention is when the first kind field of media file calls player failure, also can attempt by inferring the content of first kind field for the field of the file format of characterizing media file in the DLNA parameter in media file and upgrading first kind field, if time also illegal for the field of the file format of characterizing media file in DLNA parameter, also can attempt by inferring the content of first kind field for the field of the file format of characterizing media file in URL and upgrading first kind field, thus call corresponding player plays media file according to the first kind field upgraded in rear media file, if do not carry first kind field or first kind field compared to media file in prior art to resolve unsuccessfully just refusal and play media file, the application can solve media file may occur that when pushing playback equipment can this media file compatible, but the problem of player failure and refusal broadcasting is called because first kind field is illegal.
