Detailed description of the invention
Embodiments of the invention are described below in detail.
One embodiment of the invention provides a kind of method with variable bit rate playing stream media video file, believes including video
Breath editor and two parts of video playback.
Specifically, video information edit segment is mainly and adds the label letter that speed is relevant in streaming media video file
Breath, comprises the steps:
Step 1.1, label information require:
Take an overall view of streaming media video file, according to point of interest or significance level, corresponding document is got ready, add self-defined
Speed label, can be any user-defined format, comprises following key message:
Play speed value；
The play start time stamp that current speed value is corresponding；
The broadcasting ending time stamp that current speed value is corresponding.
Step 1.2, two kinds of presentation modes of label information:
The first, generate extra label information file with streaming media video file synchronization, comprise and meet step 1.1 requirement
All label substances, file format does not limits；Or
The second, label information writes streaming media video file internal as custom field, for the stream of different-format
Media video file, customized label should meet the specification of this video file itself, and such as MP4 file is that box, FLV file is
Tag etc., define according to the container of file format self, and presentation mode is had nothing in common with each other.
Specifically, the handling process of video playback part comprises the steps:
Step 2.1, judge user for current streaming media video file whether have selected unlatching director editing pattern, as with
Family does not select, then ignore speed label and describe, and plays files in stream media to be broadcast by normal logic of playing, otherwise jumps
Forward step 2.2 to process.
Step 2.2, the resolver example of one streaming media video file to be broadcast of initialization, resolver is to currently treating
Broadcast file and make pretreatment, it is judged that whether file exists self-defined speed label, work as if it did not, play by normal broadcasting logic
Before files in stream media to be broadcast, otherwise jump to step 2.3 and process.
Step 2.3, the speed label information that parsing media file is corresponding, construct a speed value, time started stamp, terminate
It is stand-by that the list structure that timestamp ternary is a group is supplied to player.Player Scan Architecture list, according to the ternary in list
Group information judges, playing video file content:
Wherein, player currently playing timestamp speed value in the ternary structural of speed list is 1, then player
According to the video content of normal speed forward present segment, until the timestamp terminated in speed ternary structural or video file knot
Bundle；
Wherein, player currently playing timestamp speed value in the ternary structural of speed list more than 1, is then play
Device is according to specifying speed value quickly to play the video content of present segment, until the timestamp terminated in speed ternary structural or regard
Frequency file terminates；
Wherein, player currently playing timestamp speed value in the ternary structural of speed list less than 1, is then play
Device according to specify speed value slow play present segment video content, until speed ternary structural in terminate timestamp or regard
Frequency file terminates.
Especially, it should be noted that, when user closes director's editing pattern in playing process, after player should be ignored
The process of continuous speed label, by normal speed forward remaining video file content part, unless at ensuing normal mode
In the process play, user opens the play mode of director's editing again.
The another aspect needing explanation especially is that the F.F. of streaming media video file is to bandwidth and the handling capacity of server
Requiring the highest, if scarce capacity, the most single video stream data cannot be play according to the high speed value specified, therefore for regarding

Condition, can additionally construct one and meet special streaming media video file claimed below:
Video file is all made up of key frame video data；
The timestamp of each key frame video data, frame data length information is comprised inside video file；
Frame video data extracts from original video stream former state, i.e. timestamp, frame data content to keep and original video stream
In completely the same,
So, when player runs into the video-frequency band content needing quickly to play, so that it may select this key frame data to constitute
Special video file, the key frame data jumping to the stamp of speed ternary label construction time started in video file corresponding is entered
Row is play, until being played in speed ternary label construction the timestamp terminated, further according to next ternary label construction, selects
Speed information described in this structure, continues quickly to play current special video file with different speed values, or switchback is original
Video file play.
In addition, it is also noted that two streams are when mutually switch, it is ensured that timestamp continuous, if after Qie Huan
Timestamp, less than the timestamp being played to before switching, easily causes player card and pauses, and contrary video pictures can be discontinuous, occurs jumping
Jump sense.
