Specific embodiment
Embodiments of the invention are described below in detail.
One embodiment of the invention provides a kind of hls video file and downloads storage and the method play, including download management
Play two parts with local.
Specifically, download management part comprises the steps:
Step 1.1, initiate http request first, download incoming hls url corresponding m3u8 file, such as download
File entitled sample.m3u8 content is as follows:
Step 1.2, the content of parsing sample.m3u8 file, create the http url row of a ts burst to be downloaded
Table.Create a destination folder, such as d:/download/sub1/sub2/, create target to be rewritten under this catalogue
M3u8 file, such as target.m3u8.
Url list in step 1.3, start to process step 1.1, initiates http request once again, downloads http: //
Sample.testdomain.com/sub1/sub2/1.ts corresponding ts slicing files, to catalogue d:/download/sub1/
Sub2/ (directory address herein is only a kind of example of the present embodiment), the file designation of download is merge.ts, and download completes
Record the total length of this document afterwards, the content rewriting target.m3u8 is as follows:
Herein it should be noted that 20,868 0 expression this ts burst positions in whole target ts file offset as 0, point
Leaf length is 20868.
Url list in step 1.4, subsequent treatment steps 1.1, continues to initiate http request, downloads http: //
Sample.testdomain.com/sub1/sub2/2.ts corresponding ts slicing files, are appended to merge.ts tail of file,
The total length of this document is recorded, the content rewriting target.m3u8 is as follows after the completion of download:
Herein it should be noted that being incremented by with burst, newly add burst should be incremented by the beginning in target ts file
Deviation post.
Url list in step 1.5, circular treatment step 1.2, until all bursts are downloaded completing, final
The content of target.m3u8 is as follows
It should be noted that source m3u8 file, if any label #ext-x-discontinuity, needs slavish copying to arrive target
Before corresponding ts burst description in m3u8 file, otherwise can lose the changes such as the timestamp that this label refers to or coded format
Information, causes player plays to arrive and processes extremely during this burst content.
Specifically, local playback unit is divided and is comprised the steps:
Step 2.1, opened by way of local file under d:/download/sub1/sub2/ catalogue
Target.m3u8 file, resolution file content, the duration according to each ts burst is (corresponding after #extinf label before burst description
Floating-point values), calculate the total duration of hls video file, create ts burst list to be played.
