Embodiment
For making the object, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.
Fig. 1 is the flow chart of the method for a kind of terminal processes video flowing of the embodiment of the present invention, and as shown in Figure 1, the method for the present embodiment comprises the following steps:
S11, terminal request are also accepted video flowing;
Described in S12, decoding terminals, when video flowing, the state of inquiry hard decoder device, if hard decoder device is busy condition, adopts soft decoder to decode.
In the present embodiment, comprise video flowing preliminary treatment, can be pre-created video flowing stored reservoir, in the time that cloud service end has a MJPEG video flowing to need terminal to show, thin terminal can arrange a unique mark (ID) for this video flowing, and this video flowing is put into video flowing stored reservoir, and video flowing stored reservoir is for managing video flowing object, so that software program can operate object video easily, raise the efficiency.
When thin terminal receives MJPEG(Motion-Join Photographic Experts Group, motion rest image (or frame by frame) compression) when video data, first according to the ID of current video data, find its corresponding video flowing object, and data are saved in corresponding video flowing object.
The process of carrying out multichannel MJPEG stream decoding processing is as follows:
In the time having a MJPEG decoding video stream request, first remove to inquire about the state of decoder, the present embodiment adopts the state of preferential inquiry hard decoder device, if the state of hard decoder device is idle, Ze Gai road video flowing uses hard decoder device to decode; Otherwise use soft decoder to decode.
Because hard decoder is an exclusive resource, if therefore hard decoder device is used, a busy indications is set need to hard decoder device, bind the ID of this road video flowing simultaneously, now hard decoder resource can not be reallocated, if the video flowing of hard decoder is released, to indications be set to the free time.
When receive MJPEG video data after, thin terminal is assigned to corresponding decoder according to the ID of current data video and decodes.
Thin terminal is carried out the demonstration of multichannel MJPEG stream and is comprised:
Create show canvas, the decoded video requency frame data of all soft decoders is combined on show canvas, wait for that window refreshes demonstration; Frame of video after hard decoder is upper screen directly, waits for that window refreshes demonstration.
When arriving after refresh time, thin terminal is initiated window refresh message, and show canvas can show video requency frame data, and the data after hard decoder also will directly refresh demonstration on screen.
In the time that cloud service end has a video flowing to discharge, can notify thin terminal, thin terminal is received after this message, video flowing object corresponding in stored reservoir can be deleted.
The embodiment of the present invention adopts the method for hard decoder and soft decoding combination, makes thin terminal possess the function that shows multichannel MJPEG video flowing.This method is used hard decoder preferential principle, can effectively utilize the high efficiency of hard solution, uses the method for soft decoding to process simultaneously and shows more video flowing.Adopt the thin terminal of the method for the embodiment of the present invention can meet the demand that current cloud computing system multiple video strems shows.
Be the video stream traffic handling process of the present invention's one application example below, as follows:
Step 101: user's (being thin terminal) initiates displaying video request to cloud service end, cloud service end is received after thin terminal request and authentication success, is responded request-reply toward thin terminal.
Step 102: thin terminal creates video flowing stored reservoir after receiving and replying, and wait for the video stream data from cloud service end.
Step 103: when thin terminal receives from cloud service Duan mono-road MJPEG video flowing, Hui Weigai road video flowing creates an object video, and for this object arrange one unique No. ID, finally this object video is put into video flowing stored reservoir.
Step 104: in the time having object video A to decode in thin terminal discovery video flowing stored reservoir, inquire about the state of thin terminal decoder.
In the present embodiment, adopt the preferential principle of hard decoder, first inquire about the state of hard decoder device, be idle condition if hard decoder device is current, object video A employing hard decoder, and hard decoder device is set to busy condition, and hard decoder is A object video by binding ID simultaneously; Otherwise adopt soft decoding.
Step 105: if thin terminal receives ID while being the MJPEG video data of A, find its corresponding object video A according to the ID of current video data, and video data is saved in object video A.Decoder corresponding in terminal is decoded to the video data in object video A.
Step 106: the data after thin terminal combinations multichannel MJPEG video decode, if object video A adopts hard decoder, directly upper screen of decoded data, waits for that window refreshes demonstration; Other adopt the object video B of soft decoding and object video C decoded data need to be combined on painting canvas, could wait for that window refreshes demonstration.
Step 107: after refresh time arrives, thin terminal can be initiated screen-refresh message, and multi-channel video stream picture is shown on screen, realizes multichannel and plays.
Step 108: Cloud Server is initiated the video A message that finishes playing, and thin terminal receives this message, and finds corresponding object video A according to video flowing No. ID.Object A is deleted from video management pond, if A adopts hard decoder, also need the resource of hard decoder to discharge, the state of hard decoder is set for idle simultaneously.
