Position parameter is to have occurred to update (illustrative, the mark updated is true).It should be noted that being connect in the present embodiment
First GOP received refers to first GOP in code stream information when entering direct broadcasting room, switching direct broadcasting room for the first time,
At this point, SPS/PPS changes, SPS/PPS update position parameter is set to and has been updated.And it is unchanged for other SPS/PPS
It the case where change (as watched same class video in same direct broadcasting room always, hard decoders are without resetting or reconnection), then keeps
Current decoding process.
Further, call soft decoder to carry out soft decoding first GOP and export image, to avoid etc. it is to be obtained
First frame video can not be decoded and be watched during hard decoders and initialization hard decoders, improve decoding efficiency, and
And soft decoding is all carried out (until hard decoders initialization finishes) in a period of time hereafter.
S2, second GOP in code stream information is received, when handling the I frame in second GOP, SPS/PPS updates position
Parameter is to have updated, but hard decoders also has not been obtained in main thread (hard decoders state is that state has not been obtained), it tries
Hard decoders are obtained, send the use request of hard decoders to sub thread or call the instruction of hard decoders.It should be noted that
If detected when I frame in second GOP the held state of hard decoders be not it is idle, illustrate hard decoders by other lines
Journey or background application are held, then video decoding thread can not obtain hard decoders, can only continue to carry out soft decoding to video,
During the GOP continued after treatment simultaneously, the held state of hard decoders is continued to test, and in the held state of hard decoders
To obtain hard decoders when the free time.
S3, handle second GOP in P frame or B frame when, after getting hard decoders, by the state of hard decoders
It is updated to be held state, and triggers hard decoders initialization, is i.e. the resetting flag bit parameter of setting hard decoders is to initial
Change mark, notice sub thread initializes hard decoders.Simultaneously by SPS/PPS update position parameter be set to do not occur update it is (exemplary
, the mark not updated is false), that is, the SPS/PPS after changing has been cached, and does not have update mark.Obtaining hard solution
During code device and initialization hard decoders, main thread still carries out soft decoding to GOP and exports image.
S4, receive third GOP in code stream information, when handling the I frame in third GOP, to each I frame into
It can all detect whether hard decoders complete initialization before row decoding, i.e. the initialization complement mark position parameter of hard decoders is
It is no that be completed, (illustrative, completed mark is true), if so, destroying current soft decoder, calls hard decoder
Device carries out hard decoder to GOP later and exports image；If it is not, soft decoded output image is still then carried out to third GOP, and
Before the I frame of each GOP later is decoded, whether detection hard decoders, which initialize, is finished.
It should be noted that if (SPS/PPS is sent out switching direct broadcasting room during carrying out hard decoder to GOP later
Changing), then hard decoders can be discharged, soft decoding is switched to, setting SPS/PPS to update position parameter is to have updated, and is then weighed
S2 to S4 is executed again.In addition, above-described embodiment is illustrated by taking first three GOP as an example, and in practical applications, due to CPU,
The influence of other threads of GPU performance or backstage, time needed for obtaining hard decoders, time needed for initialization hard decoders are equal
It can not determine, therefore, the operations that above-mentioned main thread executes are likely to occur in other GOP.
Fig. 4 is the flow diagram of sub thread in a kind of application for video encoding/decoding method that the embodiment of the present invention one provides.
As shown in figure 4, whether sub thread cycle detection hard decoders are original state or are held state, when hard decoders are initial shape
State, sub thread receive the use request of the hard decoders of main thread transmission or call the instruction of hard decoders, then the hard solution of creation
The state of hard decoders is simultaneously set to the state of having not been obtained by code device, and continues cycling through the state of detection hard decoders.It needs to illustrate
It is after hard decoders under the state that has not been obtained are held by main thread, state will be updated to be held.When hard decoders are to be held
When state, whether the resetting flag bit parameter that sub thread continues to test hard decoders is mark to be initiated, if it is, initially
Change hard decoders, call the relevant internal interface of hard decoders, is passed to SPS/PPS, and after the completion of hard decoders initialization, it will
The resetting flag bit parameter of hard decoders, which is set to, is not required to initialization (illustrative, the mark for being not required to initialization is false), will be hard
The initialization complement mark position parameter of decoder, which is set to, to be completed；If it is not, then cycle detection hard decoders whether be it is initial or
It is held state.
