Description
Technical Field
The invention relates to the field of video playing, in particular to the field of real-time video playing, and particularly relates to a playing method based on real-time video playing fluency.
Background
With the gradual attention of the public transportation industry to the field of safety precaution, the demand for real-time video monitoring is increasingly strong, the requirement for higher user experience on the real-time video playing fluency is met, and the real-time video playing fluency becomes a problem which is concerned with under the eye. Currently, video playing technologies in the industry all implement a video playing mechanism according to a technical route of a standard frame, for example, CN105847967A discloses a video playing control method, which includes: receiving a first video frame and inserting the first video frame into a cache region; predicting a second transmission jitter of a video frame next to a first video frame according to first transmission jitters of a plurality of video frames including the first video frame relative to a video frame received before the first video frame; acquiring the playing time of the second video frame which is output by the cache region latest; and determining the waiting time from the playing time of the second video frame to the next video frame of the second video frame according to the second transmission jitter. However, when a plurality of video windows are opened simultaneously to share a fixed limited network bandwidth, a phenomenon that video is blocked and waiting for loading frequently occurs, and particularly, when the network environment condition is poor, a video blocking phenomenon is more likely to occur, and the user experience degree is seriously affected.
Disclosure of Invention
In view of the above disadvantages in the prior art, an object of the present invention is to provide a smooth playing method based on real-time video playing.
In order to achieve the above purpose, the present invention provides a playing method based on smooth real-time video playing, which adopts the following technical scheme:
a playing method based on real-time video playing fluency comprises the following steps:
1) requesting a real-time video source code stream according to a media service communication protocol;
2) storing the received real-time video source code stream data into a buffer memory;
3) monitoring the data capacity in the memory in real time, reading the memory data when the memory capacity is larger than or equal to the calibrated playing capacity, starting decoding, and firstly searching frame information of the SPS from the memory to ensure that a video decoder can normally decode;
4) the speed of decoding varies according to the size of the memory data: when the memory capacity is larger than the calibrated equilibrium capacity, subdividing the capacity area according to the actual capacity to realize different decoding acceleration speeds; when the actual capacity is not larger than the calibrated equilibrium capacity, subdividing the capacity area according to the actual capacity to realize different decoding speed reduction, thereby ensuring that the memory data cannot overflow and the memory data cannot be consumed and exhausted, and achieving dynamic balance of the memory;
5) and drawing the decoded picture resources on a video playing control so as to achieve the effect of smooth real-time video playing.
Further, the buffer memory is a ring memory.
Furthermore, the real-time video source code stream data is added to the tail of the annular memory, and decoding is started from the head of the annular memory.
Compared with the prior art, the realization of the application technology takes the dynamic balance of the video flow capacity in the memory as the core, achieves the technical effect of smooth real-time video playing, and has obvious smoothness experience effect compared with the technical route of the current standard frame.
Drawings
Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:
fig. 1 is a flow chart of embodiment 1 for smooth real-time video playback.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
Example 1
As shown in fig. 1, a method for smoothly playing a video in real time includes the following steps:
1) requesting a real-time video source code stream according to a media service communication protocol;
the media service communication Protocol is RTSP (Real Time Streaming Protocol) or RTMP (Real Time Messaging Protocol).
2) Storing the received real-time video source code stream data into a ring buffer memory;
the whole real-time video source code stream data is transmitted to a buffer memory, and digital signals in the buffer memory are converted into analog signals to be output at the later stage.
3) Monitoring the data capacity in the annular memory in real time, reading the memory data when the annular memory capacity is larger than or equal to the calibrated playing capacity, starting decoding, and firstly searching frame information of an SPS (Sequence Parameter Set, SPS for short) from the memory, wherein the SPS frame is very small and is less than 100 bytes, so that a video decoder can normally decode; the real-time video source code stream data is added to the tail of the annular memory, and decoding is started from the head of the annular memory;
4) the speed of decoding varies according to the size of the ring memory data: when the memory capacity is larger than the calibration balance capacity (calibration capacity), subdividing the capacity area according to the actual capacity size to realize different decoding speed acceleration, for example, the decoding speed is accelerated from 30 frames/second to 80 frames/second; when the actual capacity is not larger than the calibrated equilibrium capacity, subdividing the capacity area according to the actual capacity to realize different decoding speed reduction, for example, the decoding speed is reduced from 30 frames/second to 25 frames/second, so that the memory data is not overflowed, and the memory data is not consumed and exhausted, so that the dynamic balance of the annular memory is achieved;
5) and drawing the decoded picture resources on the video playing control, namely sequentially loading the decoded video source code stream data to the video playing control so as to achieve the effect of smooth real-time video playing.
As can be understood by those skilled in the art, a video playing control may be displayed in a user interface of the client, for example, and the user may trigger the video playing control in different manners, such as clicking, to obtain the video.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
