Downloading this part TS segment is abandoned, to improve the downloading success rate of Streaming Media and the ornamental experience of user.
It in other embodiments of the invention, specifically can be according to the segment of the TS segment of the second number in above-mentioned steps 102
Information of number and/or clip durations information come judge its whether meet it is preset abandon downloading condition, for example, following two can be passed through
Item judgement:
A): judging the segment number of the TS segment of second number whether less than the first preset number；
B): judging the total duration of the TS segment of second number whether less than the first preset duration；
If above-mentioned, a), b) two judging results are to be, it is preset to determine that the TS segment of second number meets
Abandon downloading condition.
It optionally, can also be by judging to download whether successfully that a part of TS segment meets accordingly in the Streaming Media
Preset condition, to judge whether the TS segment of the second number of the failed download can be abandoned downloading indirectly.
Preferably, in other embodiments of the invention, after abandoning downloading the TS segment of second number, in order to just
The broadcasting Streaming Media that can be smooth in the player of client, can delete the m3u8 for playing the Streaming Media and describe file
In include the second number TS segment information so that player is when describing file playing stream media according to the m3u8, from
It is dynamic to skip part TS segment, continue other TS segments of played in order.
Alternatively, client can also be timely according to the number for downloading successful TS segment when needing to play the Streaming Media
Long, available m3u8 describes file when being spliced into local play again.Specific method is, according to the piece for downloading successful TS segment
The broadcasting end m3u8 that number of segment mesh, corresponding duration and indexed sequential establish the Streaming Media describes file；And according to the broadcasting end
M3u8 describes file and plays the Streaming Media.
It in other embodiments of the invention, can be with specific reference to following sub-step 1011 to 1014 in above-mentioned steps 101
Obtain the download address information of the TS segment of first number:
Step 1011: obtaining the newly downloaded address information of the Streaming Media.
Specifically Streaming Media to be downloaded can be utilized according to source server or the similar information collecting server for taking off worm program is taken off
Key message, the address of web page address information and/or the Streaming Media where such as duration information and/or the Streaming Media
The name information of information and/or the Streaming Media is found the data source of the Streaming Media on major Streaming Media website, is being found
When, target data source is matched or calibrated with above-mentioned key message, to determine whether it is same with Streaming Media to be downloaded
One Streaming Media, if successful match, the address information of the target data source be the Streaming Media to be downloaded newly downloadedly
Location information.
Step 1012: file is described according to the new m3u8 that the newly downloaded address information obtains the Streaming Media.
Step 1013: the newly downloaded address letter of the TS segment of the first number described in file acquisition is described according to the new m3u8
Breath.
Step 1014: the TS of first number is replaced according to the newly downloaded address information of the TS segment of first number
The former download address information of segment.
With reference to background technique it is found that sometimes server may cut again Streaming Media, it is also possible to not cut again
It cuts, and is only updated the download address information of certain TS segments therein.If it is the first situation, due to again
Cutting, the TS that the TS segment and the Streaming Media to be downloaded for causing the Streaming Media of other loading sources obtained on the net to include include
Segment is different, therefore possibility can not in the Streaming Media of other loading sources for the TS segment of the first number of failed download
Accurately match.And it then can guarantee the complete phase of TS segment that the Streaming Media of other loading sources is included in the latter case
Together, it can just describe to get the TS with the first number in file from the m3u8 of the Streaming Media of other loading sources in this case
The download address information for the TS segment that segment matches completely, and by the download address change dump into former download path, after
The continuous TS segment for downloading first number.
In practical applications, due to m3u8 describe the download address in file failure frequency it is very high, repeat
Using the method for preset one or many above-mentioned steps 101, i.e., repeatedly replace the address information of the TS segment of failed download.
