Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
See Fig. 1, propose video broadcasting method one embodiment of the present invention, described video broadcasting method comprises the following steps:
Step S10: be yuv format by video data decoding
Video play device reads current shooting, local store or outside (as sent by network) video data sent.This video data is the packed data that obtains after video compression algorithm compression, described compression algorithm as H.263, H.264, H.265, AVI, MPEG4 etc.
Video play device utilizes the video data of the compression algorithm of prior art Plays to compression to carry out video decode, be decoded as the video data of yuv format, the original video source data that the video data of yuv format captures when being video acquisition, primarily of YUV tri-component compositions.
Step S11: the video data playing yuv format
Concrete, by the video data of yuv format write video card internal memory, (video card internal memory is mapped as one section of memory headroom by operating system to video play device, and the address of this memory headroom is provided, the video data of yuv format is directly copied to corresponding memory headroom address by video play device), and by video card internal memory, the broadcast window that the video data of yuv format exports display to is shown, reach the effect of video playback.This play mode can display video image fast, and display efficiency is higher, and therefore common video playback all adopts this pattern.
Step S12: detect the video image play and whether show exception
Video play device real-time or timing detection play video image whether show exception, such as, in playing process, carry out one-time detection at set intervals.There is the problems such as display mistake, Hua Ping, blank screen in the abnormal video image that comprises of video image display.
When detecting that video image display is abnormal, then enter step S13, carry out abnormal restoring; Otherwise, keep current broadcast mode, proceed to detect.
Step S13: video data is converted to rgb format from yuv format
When detecting that video image display is abnormal, video play device is then changed the form of video data, namely utilize transfer algorithm general in prior art that video data is converted to rgb format from yuv format, the video data of rgb format forms primarily of RGB three primary colors.
Step S14: the video data playing rgb format
Concrete, video play device directly exports the video data of each frame rgb format to broadcast window as single image and is shown.Although this play mode reduces display efficiency because needing video data to carry out the conversion once from yuv format to rgb format, but due to without the need to accessing display card internal memory, therefore there is device independence, namely concrete video card type and the compatibility of video card is not limited to, therefore there is higher stability during displaying video, the normal display of video image can be ensured.
As shown in Figure 2, whether the video image detecting broadcasting in abovementioned steps S12 shows exception, specifically comprises the following steps:

Described reference point can be some points that are random on broadcast window or that specify according to certain rule in advance.Or, broadcast window is divided at least two regions, then obtains the coordinate of the geometric center in each region, the geometric center in each region is chosen for reference point.
In specific implementation, as shown in Figure 3, video play device obtains the coordinate range of broadcast window by operating system interface, the X in the broadcast window lower right corner, Y-axis coordinate is deducted X, the Y-axis coordinate in the window upper left corner, obtains the width of broadcast window and height.According to width and the height of broadcast window, broadcast window is on average divided into some regions 10 (as two regions, four regions, nine regions, 16 regions etc., areal is not limit), again directly by width and highly divided by region 10 number divided, obtain the width in each region 10 and height.Finally, by the width in each region 10 and highly divided by two, obtain the X of the geometric center 20 in each region 10, Y-axis coordinate, the geometric center 20 in each region 10 is chosen for reference point.
In theory, the reference point chosen is more, and the testing result of acquisition is more accurate, and the reference point therefore chosen is The more the better.
Step S122: judge whether the rgb color information of video image and the rgb color information of decoded video data mate
The rgb color information of the video image corresponding to each reference point and the rgb color information of decoded video data are contrasted; When the two the rgb color information of comparing result corresponding to each reference point all mates (namely identical), then think the rgb color information of video image and the rgb color information match of decoded video data, enter step S123, judge that video image display is normal; When the two the rgb color information of comparing result corresponding at least one reference point does not mate (namely not identical), then think that the rgb color information of video image and the rgb color information of decoded video data do not match, enter step S124, judge that video image display is abnormal, as there is the problems such as display mistake, Hua Ping, blank screen.
Step S123: judge that video image display is normal
Step S124: judge that video image display is abnormal
Video broadcasting method of the present invention, is first yuv format by video data decoding, carries out video playback by high efficiency play mode; In video display process, the video image play is detected, when detecting that the video image display of broadcasting is abnormal, then video data is converted to rgb format from yuv format, with relative inefficiencies but stable play mode carries out video playback, thus make video image be recovered normal display timely, ensure that the normal play of video.
