Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Fig. 1 is the flow chart of the caching method of a kind of TS video in the embodiment of the present invention.As shown in Figure 1, the method comprises the following steps S11-S14:
Step S11, receives current just at the pre-play instruction of live TS video.
Wherein, pre-play instruction is the playing request of user to live TS video, can be used for TS video when starting to play, when also can be used for F.F., rewind.
Step S12, determines the position that pre-play instruction is corresponding in TS video.
In this step, because pre-play instruction is the playing request of user to the online TS video play, and due to TS form video not special head file the duration information of video is described, also total playing duration of TS large files cannot just be obtained, the progress bar of therefore TS video is display from 0 to 100% percentage, the not length of displaying time, therefore, the position that pre-play instruction is corresponding in TS video is also characterize with the percentage in this TS video file, in the process of buffering TS video, also without the need to downloading the head file of TS video.
Step S13, according to predetermined first buffer threshold, the single-threaded buffer memory TS video in position, the first buffer threshold is equal to or greater than in TS video the amount of video transmitted between adjacent twice decoded information.
In this step, the first buffer threshold also can be determined according to the resolution of TS video and/or code check.The amount of choosing of the first buffer threshold is generally and can ensures that user normally watches the minimal buffering amount of TS video, this minimal buffering amount only need comprise in TS video the amount of video transmitted between adjacent twice decoded information, therefore when user sends pre-play instruction, only need carry out buffered video with minimal buffering amount, thus the cache-time before making displaying video shortens.
Step S14, when buffer memory reaches the first buffer threshold, according to predetermined second buffer threshold multithreading buffer memory TS video, the second buffer threshold is greater than the first buffer threshold.
Wherein, second buffer threshold is in the process play online at TS video, the data volume of required buffer memory during the buffer memory of broadcasting limit, limit, here the mode buffer memory TS video of multithreading is adopted, the video of buffer memory can be carried out the process such as decapsulation, decoding while making buffer memory, thus enable TS video Continuous Play.
Adopt the technical scheme that the embodiment of the present invention provides, can in the optional position of TS video, according to the single-threaded buffered video of predetermined buffer threshold, and switch to larger buffer threshold multithreading buffered video after having cushioned, not only make user when watching TS video without the need to waiting for the time of long buffered video, and do not affect the Continuous Play of video, improve the Experience Degree that user watches video.
In one embodiment, as shown in Figure 2, said method can also be embodied as following steps S21-S25:
Step S21, receives current just at the pre-play instruction of live TS video.
Step S22, determines the position that pre-play instruction is corresponding in TS video.
Step S23, stop the current ongoing pre-playback process to TS video, pre-playback process comprises at least one in buffer memory, decapsulation, decoding.
Step S24, according to predetermined first buffer threshold, at position buffer memory TS video.This first buffer threshold is equal to or greater than in TS video the amount of video transmitted between adjacent twice decoded information.
Step S25, when buffer memory reaches the first buffer threshold, according to predetermined second buffer threshold buffer memory TS video, carries out decapsulation or decoding process to the TS video that buffer memory completes simultaneously.Wherein, the second buffer threshold is greater than the first buffer threshold.
In the present embodiment, step S23-S24 is a kind of execution mode of step S13, and step S25 is a kind of execution mode of step S14.When receiving the pre-play instruction to TS video, stop the processes such as the current ongoing buffer memory to TS video, decapsulation or decoding, thus releasing resource, fast cache TS video.Such as, user asks to play TS video, so in the starting position of TS video, first with the first buffer threshold buffer memory TS video, if the first buffer threshold is 5M, then after the TS video data of buffer memory 5M, start to play the TS video data of buffer memory, simultaneously, continue buffered video with the buffer threshold (such as 10M) larger than the first buffer threshold, this process of caching is the process of multithreading, namely while buffer memory TS video, the video data of buffer memory is carried out to the process of decapsulation, decoding, to guarantee that video can Continuous Play.In addition, can also when reaching preset duration according to the first buffer threshold buffer memory TS video or reach default data volume, use the second buffer threshold buffer memory TS video again instead, wherein, preset duration is generally a shorter time period, and when the first buffer threshold is less, user probably experiences less than this shorter time period, also just make user when watching live TS video, the time of wait is shorter.The data volume preset is the data volume of the TS video normal play that can ensure buffer memory.
In one embodiment, as shown in Figure 3, said method can also be embodied as following steps S31-S36:
Step S31, receives current just at the pre-play instruction of live TS video.
Step S32, determines the position that pre-play instruction is corresponding in TS video.
Step S33, judges whether pre-play instruction is the pre-play instruction received first.If pre-play instruction is the pre-play instruction received first, then continue to perform step S34; If the pre-play instruction of pre-play instruction not for receiving first, continuous execution step S35.
Step S34, while buffer memory TS video, obtains the decoded information of TS transmission of video according to predetermined first buffer threshold from this position.Continue to perform step S36.
Step S35, while buffer memory TS video, obtains decoded information accessed when receiving pre-play instruction first according to predetermined first buffer threshold from this position.Continue to perform step S36.
Step S36, when buffer memory reaches the first buffer threshold, according to predetermined second buffer threshold multithreading buffer memory TS video, the second buffer threshold is greater than the first buffer threshold.
In the present embodiment, if the pre-play instruction of pre-play instruction not for receiving first, such as, when F.F. or rewind video, when with the first buffer threshold buffer memory TS video, without the need to again obtaining decoded information again, the decoded information got when only need continue to use this TS video of buffer memory first, thus save identification and the acquisition process of decoded information, also just save the stand-by period of user and the burden of server.
