Embodiment
Embodiment of the present invention provides an embodiment, and present embodiment provides a kind of player method of network video file, and this method comprises as shown in Figure 1:
S11, receive user's order video order after, download the video data of the 1K at the most of the corresponding video file of this order; Promptly download the video data that is no more than 1K at most;
The scope suggestion of above-mentioned 1K at the most uses 100 bytes between the 1K, and the user also can freely set in actual conditions certainly.
S12, judge the form of the correspondence of this video file according to the video data of this 1K;
S13, from the minimum data tabulation of storage in advance, determine the minimum data of this corresponding form correspondence according to this corresponding form;
S14, downloaded the minimum data of this form correspondence after, give the flash control with this minimum data and begin displaying video.
After the method that present embodiment provides is judged the form of this video file correspondence by the video data that is downloaded to many 1K, from the tabulation of storage in advance, determine the minimum data of this form correspondence according to this form, after having downloaded this minimum data, give the flash control with minimum data and begin displaying video.Because this method only need have been downloaded minimum data and can carry out the broadcast of video file, the data downloaded amount is little, and the time of loading is shorter, the user experience height.
The present invention also provides another embodiment, and present embodiment provides a kind of player method of network video file, and the technology scene that present embodiment is realized is, video file is an example with FLV (flash video) form, and this method comprises as shown in Figure 2:
S21, receive user's order video order after, the video data of the 1K at the most of the video file of foradownloaded video order correspondence;
S22, the form of judging this video file according to the video data of this 1K are the FLV form;
S23, from the minimum data tabulation of storage in advance, determine the minimum played data of this FLV correspondence to be specifically as follows FLV Header (header)+first tag according to this FLV form; Wherein the FLV file format is as shown in table 1:
Table 1:
Header+ file attribute tag in the above-mentioned minimum played data correspondence table 1.
Above-mentioned first tag can be, metadata onMetaData.Optionally, after determining minimum played data, can detect, as detect this video file and do not have first tag, and determine that this first tag is 0, promptly need not to download first tag video file.
The manufacture method of above-mentioned minimum data tabulation can for, obtain the form of video file commonly used, respective standard according to concrete form correspondence is determined minimum data, for example, as the FLV form, then " the Video File Format Specification Version 9 " with reference to Adobe company determines that this minimum data is FLVHeader (header)+first tag; MP4 form and for example, then " the QuickTimeFile Format Specification " with reference to Adobe company determines that this minimum data is MP4 file header+moov atom.
The concrete form of above-mentioned MP4 can be referring to the description of Table 1 among the ISO/IEC 14496-12:2005 (E).
Ftyp (4.3) among the corresponding Table 1 of above-mentioned MP4 file header+moov atom need to prove wherein that to subs (8.42) data of band " * " are essential data among the Table 1, not with * " data be optional data; Among the above-mentioned ftyp (4.3) 4.3 is to the numbering of data ftyp among the Table 1; 8.42 of subs (8.42) is to the numbering of data subs among the Table 1.
The length that it should be noted that first tag of each video file correspondence is not definite value, is that first tag of the video file 1 of FLV can be 1K as form, and first tag of the video file 2 of form FLV can be 2K; In like manner, the length of the moov atom of each video file correspondence is not definite value.
S24, after having downloaded first tag data of FLV Header+, give the flash control with first tag data of FLV Header+ and begin displaying video.
After the method that present embodiment provides is judged this video file and is the FLV form by the video data that is downloaded to many 1K, the minimum data amount of determining this video file correspondence according to this FLV form from the tabulation of storage in advance is first tag of FLV Header+, after having downloaded first tag of FLV Header+, give the flash control with first tag data of FLVHeader+ and begin displaying video.Because this method only need have been downloaded first tag of FLV Header+ and can carry out the broadcast of video file, and first tag of FLV Header+ affirms less than the 2M data volume, so its data downloaded amount is little, so the time of its loading is shorter, and the user experience height.
The present invention also provides another embodiment, and the technology scene that present embodiment is realized is, the video file of present embodiment is an example with the MP4 form, and this MP4 is the broadcast format of video file; This method comprises as shown in Figure 3:
S31, receive user's order video order after, the video data of the 1K at the most of the video file of foradownloaded video order correspondence;
S32, the form of judging this video file according to the video data of this 1K are the MP4 form;
S23, from the minimum data tabulation of storage in advance, determine the minimum played data of this MP4 correspondence to be specifically as follows MP4 file header+moov atom according to this MP4 form;
Optionally, after determining minimum played data, can detect, as the video file that detects this MP4 form do not have moov atom, and determine that this moov atom is 0, promptly need not to download moovatom video file.
S34, after having downloaded MP4 file header+moov atom data, give the flash control with MP4 file header+moov atom data and begin displaying video.
After the method that present embodiment provides is judged this video file and is the MP4 form by the video data that is downloaded to many 1K, the minimum data amount of determining this video file correspondence according to this MP4 form from the tabulation of storage in advance is MP4 file header+moov atom, after having downloaded MP4 file header+moov atom, give the flash control with MP4 file header+moov atom data and begin displaying video.Because this method only need have been downloaded MP4 file header+moov atom and can carry out the broadcast of video file, and MP4 file header+moov atom affirms less than the 2M data volume, so its data downloaded amount is little, so the time of its loading is shorter, and the user experience height.
The present invention also provides a kind of playing device of network video file, and this device comprises as shown in Figure 4:
Receive download unit 41, after being used to receive user's order video order, download the video data of 1K at the most of the video file of this video commands correspondence, determine the form of this video file correspondence according to the video data of described 1K at the most;
Search broadcast unit 42, be used for finding out the minimum data of this form correspondence from the minimum data tabulation of storage in advance according to described form, downloaded this corresponding minimum data after, give the flash control with described minimum data and begin displaying video.
