Detailed description of the invention
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is carried out clear, complete description, it is clear that described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of protection of the invention.
The embodiment of the present invention, whether application program (being specifically as follows video player) inquiry graphic process unit GPU supports the decoding of video to be decoded, if supported, then obtain corresponding decoding capacity information, judge that the decoding capacity information obtained is the truest, if it is true, then by described GPU, video to be decoded is decoded, if GPU does not support the decoding of video to be decoded, or the decoding capacity information of acquisition is untrue, then by default decoding process, video to be decoded is decoded, such that it is able to improve the safety and reliability of video decoding process.
GPU decoding capacity information can include rough decoding capacity information and accurate decoding capacity information.nullRough decoding capacity information is the information that can limit roughly GPU decoding capability，Such as the information of decoding capability for GPU definition in the DXVA specification listed in table 1，The mode of operation that the video that GPU can support decodes is may determine that by these rough decoding capacity information，Wherein comprise two parts information，A part of information is the video code model (H261 supported、H263、H264、MPEG2 etc.)，Such as " DXVA_ModeH261_A " shows that GPU can support the decoding of the video of H261 coded format，Another part information is A therein、B、C、D represents the decoding step that GPU can complete when being decoded the video of certain coded format，Such as，The coded format of H261 includes two steps during decoding，" DXVA_ModeH261_A " shows that GPU has been merely able to first step，Remaining step needs to be completed by CPU，" DXVA_ModeH261_B " then represent GPU can complete independently H261 video decoding two steps.Accurately decoding capacity information is the information that can accurately limit GPU decoding capability, decoding configuration (resolution, code check, caching frame number, color space form etc.) can supported when the video of certain coded format is decoded such as GPU, such as, certain GPU is under the mode of operation of DXVA_ModeH261_B, it would be preferable to support the resolution of 1280 × 720, the code check of 2000kbps, the caching frame number of 22 and the color space form of NV12.
As it is shown in figure 1, the handling process of video encoding/decoding method provided for the embodiment of the present invention, specifically include following steps:
Step 101, whether application program inquiry GPU supports the decoding of video to be decoded, if supported, then performs step 102, otherwise, performs step 105.
Concrete, whether application program inquiry GPU supports that the process of the decoding of video to be decoded may include steps of:
Step one, application program obtains the rough decoding capacity information of GPU.
When there being video to be decoded to need to be decoded, application program can pass through system program (such as windows(form) operating system) set up the connection with the driver of GPU.Concrete, application program generates DXVAOutput(output) Pin(interface), and use DXVAOutputPin to be connected to VMR(VideoMixingRenderer, VMR) IAMVideoAcceleratorInputPin(windows system provide for application program connect GPU driver interface, GPU drive connection interface can be referred to as, belong to the one of DXVA interface), generate corresponding FilterGraph(filter figure, it is exactly multiple linking together, complete specific function (such as video playback, Video Capture) the combination of filter).
After the connection of the driver of application program foundation and GPU, can be to the rough decoding capacity information of driver inquiry GPU, after driver receives query statement, send the rough decoding capacity information of GPU to application program, the rough decoding capacity information such as this GPU includes DXVA_ModeH261_B, DXVA_ModeH263_B, DXVA_ModeMPEG1_A, DXVA_ModeMPEG2_B etc..
Step 2, when the rough decoding capacity information obtained exists the rough decoding capacity information of the coded format supporting video to be decoded, application program continues whether inquiry GPU supports the decoding configuration information of video to be decoded under the mode of operation that this rough decoding capacity information is corresponding, if it is, show that step 101 Query Result is the decoding that GPU can support video to be decoded.If the rough decoding capacity information obtained does not exists the rough decoding capacity information of the coded format supporting video to be decoded, or inquire GPU under this mode of operation, do not support the decoding configuration information of video to be decoded, then show that the Query Result of step 101 is the decoding that GPU can not support video to be decoded.
Concrete, application program can get coded format and the decoding configuration information of this video from the file of video to be decoded, this coded format can include H261, H263, H264, MPEG2 etc., and this decoding configuration information can include the information such as resolution, code check, caching frame number, color space form.
Concrete, application program searches the rough decoding capacity information of the coded format that can support video to be decoded in the rough decoding capacity information that driver reports, if able to find, the most further the decoding configuration information of this rough decoding capacity information and video to be decoded is sent to GPU driver, to inquire about whether GPU supports to decode configuration accordingly under corresponding mode of operation.nullSuch as (decoding configuration information only illustrates as a example by resolution and code check herein)，The coded format of certain video is H261，Resolution is 1280 × 720，Code check 2000kbps，And assume that GPU supports the mode of operation of DXVA_ModeH261_B，And the highest can support 1280 × 720 resolution、The code check of 3000kbps，After video player finds DXVA_ModeH261_B in driver reports rough decoding capacity information，By DXVA_ModeH261_B、1280 × 720 and 2000kbps are sent to driver，Under the mode of operation of DXVA_ModeH261_B, the resolution of 1280 × 720 and the code check of 2000kbps whether is supported with inquiry GPU，Driver can return the information of " support ".
Step 102, application program obtains corresponding decoding capacity information.Concrete, this decoding capacity information includes the rough decoding capacity information supporting the coded format of video to be decoded, and the accurate decoding capacity information corresponding with the decoding configuration information of video to be played.
Continue to apply above-mentioned example to illustrate, when video player confirms resolution and the code check of 2000kbps that GPU can support under the mode of operation of DXVA_ModeH261_B 1280 × 720, video player just can confirm that in the decoding capacity information of GPU, rough decoding capacity information is DXVA_ModeH261_B, and accurate decoding capacity information is resolution and the code check of 2000kbps of support 1280 × 720.
Step 103, application program judges that the decoding capacity information obtained is the truest, if truly, then performs step 104, otherwise, performs step 105.
Concrete, application program is performed by the Execute(of GPU drive connection interface (above-mentioned IAMVideoAcceleratorInputPin)) function, it is judged that the decoding capacity information of acquisition is the truest.The most permissible, first the structure DXVA_ConfigQueryOrReplyFunc to Execute function carries out the assignment of QueryOrReplyFlag=0xFFFFF1, bDXVA_Func=1；Then obtaining the return value of Execute function, when described return value is 0, the decoding capacity information of acquisition is true, and when described return value is not 0, the decoding capacity information of acquisition is untrue.
Step 104, video to be decoded is decoded by application program by GPU.
Concrete, application program first determines the decoding interface that the decoding capacity information of acquisition is corresponding, then by this decoding interface, video to be decoded is sent to described GPU and is decoded.While GPU is decoded, decoding video is carried out display output.
Step 105, video to be decoded is decoded by application program by default decoding process.Wherein, default decoding process is default decoding process, can be other decoding processes outside GPU decoding, can according to circumstances preset.
Preferably, video to be decoded is decoded by application program by soft decoding process.Concrete, first, application program disconnects the connection with IAMVideoAcceleratorInputPin, i.e. destroys corresponding FilterGraph(filter)；Then, application program sets up the connection with video output interface, and such as application program can generate YV12OutputPin(and carry out the interface that video shows, referred to as video output interface), YV12OutputPin is used to be connected to the YV12InputPin of VMR, to regenerate FilterGraph；Video to be decoded is decoded, and by video output interface, decoding video is carried out display output.
