Formula is described in further detail.
Referring to FIG. 1, it illustrates the method streams of length measuring method when video head frame provided by one embodiment of the present invention
Cheng Tu.Length measuring method may include steps of when video head frame:
Step 101, video web-pages to be measured are opened, record was the first moment at the time of opening video web-pages.
Specifically, terminal calls CreateThread system function to create first frame duration by main thread measures thread, when
After long measurement thread operation, terminal measures thread by duration and opens video web-pages to be measured, and record opens video web-pages
Moment was the first moment, and according to the browser program path and measurement recorded in the browser program path variable for participating in test
Video web-pages page address be parameter call CreateProcess system function create browser process example.
Step 102, the corresponding video interception of video in video web-pages is obtained, the picture that color value is different in video interception is counted
The quantity of element.
Optionally, terminal obtains the corresponding video interception of video in video web-pages every scheduled duration, counts video interception
The quantity of the different pixel of middle color value.Wherein, scheduled duration can be 0.5s, 1s, 2s, tool of the present embodiment to scheduled duration
Body duration does not do any restriction.
It step 103, is the at the time of recording quantity greater than pre-set color threshold value if quantity is greater than preset color threshold
Two moment.
Due to video head frame broadcasting before, the picture that video region show in video web-pages be usually blank screen, extensively
Announcement, LOGO of video website etc., therefore preset color threshold can be the number of the different pixel of color value in blank screen picture
Amount, the different quantity of pixel of color value in advertisement picture, in the LOGO picture of video website the different pixel of color value number
Amount etc..If in the video web-pages that terminal is got in the corresponding video interception of video, the quantity of the different pixel of color value
Greater than preset color threshold, illustrate that the picture that current video region is shown is not blank screen, advertisement, video website
LOGO, but video head frame, when terminal record current time (at the time of i.e. quantity is greater than pre-set color threshold value) is second at this time
It carves.
Specifically, duration measurement thread first calls GetWindowDC system function to obtain browser window DC handle, then adjust
Memory DC handle is created with CreateCompatibleDC, then calls CreateCompatibleBitmap creation video place
The memory bitmap in region simultaneously records the memory bitmap handle, secondly calls BitBlt by video region in browser window
Bitmap data copies in the Installed System Memory that memory bitmap handle is indicated, and finally calls GetDIBits system function by video
Then the bitmap data of region traverses the bitmap of video region from being copied in application program memory in Installed System Memory
The color value of each pixel in data, and the quantity of the different pixel of statistical color value, if the different pixel of color value
Quantity is less than or equal to preset color threshold, illustrates that video head frame does not play, if the quantity of the different pixel of color value is greater than
Preset color threshold illustrates that video head frame is played.
Step 104, the second moment was subtracted into for the first moment, obtains the first frame duration of video in video web-pages.
In the video web-pages to be measured obtained due to the second moment for terminal in the corresponding video interception of video, color value
At the time of the quantity of different pixels is greater than preset color threshold, the first moment was that terminal opens video web-pages to be measured,
Therefore, the second moment was subtracted into for the first moment, user can be obtained since opening video web-pages, to watching in the video web-pages
First frame video terminates duration used, i.e., the first frame duration of video in the video web-pages.
In conclusion length measuring method when video head frame provided in an embodiment of the present invention, opens video web-pages by record
At the time of be the first moment, obtain video web-pages in the corresponding video interception of video, count video interception in color value it is different

Flow chart.Length measuring method may include steps of when video head frame:
Step 301, obtained from preset configuration file video web-pages list to be measured, preset color threshold, to
The corresponding relationship of the display area of video in the web page address and video web-pages of the video web-pages of measurement.
Wherein, the web page address for there are multiple video web-pages to be measured is recorded in video web-pages list to be measured.
It should be noted that the web page address recorded in video web-pages list can be the same webpage of same video website
Address can be the different web pages address of same video website, can also be the different web pages address of different video website.Its
In, the web page address of each video web-pages to be measured respectively corresponds the display area of video in a video web-pages.
Step 302, the web page address recorded in video web-pages list to be measured is traversed, determines the webpage not being labeled
Address.
Wherein, the web page address not being labeled is the web page address that terminal does not carry out the measurement of video head frame duration, is labeled
Web page address be terminal carried out video head frame duration measurement web page address.
Step 303, first item web page address is obtained in never labeled web page address, first item web page address is determined
For the web page address of video web-pages.
Step 304, video web-pages to be measured are opened, record was the first moment at the time of opening video web-pages.
Step 305, according to pair of the display area of video in the web page address and video web-pages of video web-pages to be measured
It should be related to, determine the display area of video in the corresponding video web-pages of first item web page address.
In the web page address and video web-pages of video web-pages to be measured in the corresponding relationship of the display area of video, record
There is the corresponding relationship of each single item web page address and the display area of video in video web-pages in video web-pages list to be measured.Eventually
After first item web page address is determined as the web page address of video web-pages by end, it can be searched in corresponding relationship and determine the first item
The display area of video in the corresponding video web-pages of web page address.
Step 306, according to the display area of video in the video web-pages determined, it is corresponding to obtain video in video web-pages
Video interception counts the quantity for the pixel that color value is different in video interception.
It step 307, is the at the time of recording quantity greater than pre-set color threshold value if quantity is greater than preset color threshold
Two moment.
Step 308, the second moment was subtracted into for the first moment, obtains the first frame duration of video in video web-pages.
Step 309, the web page address of the video web-pages is marked in video web-pages list to be measured.
After terminal obtains the first frame duration of video in video web-pages, then label should in video web-pages list to be measured
The web page address of video web-pages shows that the video web-pages have been measured.
Since record has the web page address of multiple video web-pages to be measured in video web-pages list to be measured, terminal exists
The test of one of video web-pages is terminated (i.e. after step 309), step 302 will to be repeated to step 309, until to be measured
Video web-pages list in the not labeled web page address that records be sky.
It should be noted that it is similar with step 101 by step 304 in this present embodiment, step 306 is similar with step 203,
Step 307 is similar with step 103, step 308 is similar with step 104, thus in this implementation no longer to step 304, step 306 to
Step 308 repeats explanation.
In conclusion length measuring method when video head frame provided in an embodiment of the present invention, opens video web-pages by record
At the time of be the first moment, obtain video web-pages in the corresponding video interception of video, count video interception in color value it is different
The quantity of pixel, record quantity were the second moment at the time of being greater than pre-set color threshold value, and the second moment was subtracted for the first moment, is obtained
The first frame duration of video into video web-pages, due to the different pixel of color value in the video pictures before the broadcasting of video head frame
Negligible amounts can effectively determine video by determining whether the quantity of the different pixel of color value is greater than pre-set color threshold value
Whether first frame plays；Therefore the method lacked in the prior art to video head frame in measurement video web-pages is solved, it can not be intuitive
The problem of determining the Video service quality of the video web-pages；Reach through measurement video head frame duration come the intuitive judgment video
The effect of the Video service quality of webpage.
In the present embodiment, configuration file further includes video web-pages list to be measured, and terminal can sequentially measure multiple videos
The first frame duration of video in webpage.
In order to avoid when terminal open multiple windows when, the window that can not be appropriately determined where video web-pages to be measured,
Configuration file further includes the process identification (PID) of preset browser, and terminal opens video web-pages to be measured, and records opening video
For after the first moment at the time of webpage, by successively by the corresponding process identification (PID) of the window opened and preset browser into
Journey mark is compared, and determines the window where video web-pages to be measured.In a kind of mode in the cards, in step
202 and step 304 after, can also carry out following step A1 to step A2.
Step A1 successively detects the corresponding process identification (PID) of the window opened, and determines whether the process identification (PID) is preset
The process identification (PID) of browser.
After step 202 and step 304, duration measures thread with the browser process example created in step 101
Handle is that parameter calls WaitForSingleObject that browser process example is waited to terminate, and time-out time is arranged.If in head
Newly created browser process is closed due to user is manual or other before frame duration measurement has not been completed,
WaitForSingleObject then returns to WAIT_OBJECT_0, and prompt terminal terminates the measurement of video head frame duration；Otherwise WAIT_
OBJECT_0 waits time-out, executes step A1.
Duration, which measures thread, to be enumerated system as parameter calling system function EnumWindows to enumerate call back function and has opened
All top-level windows, and called in enumerating call back function by parameter of the window handle that is currently enumerated
GetWindowThreadProcessId, to obtain process identification (PID) belonging to the window handle being currently enumerated, by the process
Mark is compared with the process identification (PID) of preset browser.
Step A2, if detecting, corresponding process identification (PID) is the window of the process identification (PID) of preset browser, and determining should
Window is the window where video web-pages to be measured.
The mistake that the process identification (PID) is compared by terminal using duration measurement thread with the process identification (PID) of preset browser
Cheng Zhong returns to TRUE if unequal, continues to enumerate next window handle；FALSE is returned to if equal, end was enumerated
Journey, and recording the window handle being currently enumerated is the window handle where video web-pages to be measured.
Optionally, since parent window and child window share a process identification (PID), and child window may be hiding not for eventually
End needs the window measured, therefore compares the process identification (PID) and the process identification (PID) of preset browser in duration measurement thread
Compared with during, if it is equal continue to call GetWindowLong continue to determine whether the window handle that is enumerated meets it is pre-
Fixed condition (for example window handle is to show that state, window handle have title bar, the parent window of window handle is NULL),
TRUE is returned if being unsatisfactory for predetermined condition, continues to enumerate next window handle, FALSE is returned if meeting predetermined condition,
Terminate enumeration process, and the window handle that then record is currently enumerated is the window handle where video web-pages to be measured.
The desktop background of terminal is not usually solid color, may when terminal is when video web-pages to be measured are not switched on
The operation for having executed screenshot statistical pixel, the picture for causing terminal to be truncated to are the desktop of the terminal, and the color value counted on is not
The quantity of same pixel is the quantity of the different pixel of the color value of desktop.Once in this way, the pixel that the color value of desktop is different
Quantity be greater than preset color threshold, terminal can then determine that video head frame is played, cause the measurement of video head frame duration wrong
Accidentally.
In a kind of mode in the cards, before step 101, step 201 and step 301, following step is executed
B1。
Step B1 deletes the icon shown on desktop, and/or, the background color of desktop is adjusted to solid color.
After step 104 and step 205, following step B2 is executed.
Step B2 restores the icon being deleted on desktop, and/or, the background color of desktop is reverted to and is adjusted to list
Color before one color.
In a kind of mode in the cards, after step 308, terminal is by the web page address of video web-pages to be measured
It is stored in tables of data with first frame duration as one group of corresponding relationship, and the video recorded in video web-pages list to be measured
After file all measures, the tables of data is exported, so that technical staff analyzes the data in tables of data, and implements phase
It should handle.
Optionally, terminal is deposited using the web page address of video web-pages to be measured and first frame duration as one group of corresponding relationship
