Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
Referring to fig. 1, a flowchart illustrating steps of a video App decoding method in the embodiment of the present invention is shown, and the specific steps include:
generally, a video APP can display and play video resource files in various formats, and a video APP in a mobile terminal decodes a video by matching a fixed hardware decoding scheme for a corresponding terminal through a terminal model. In the invention, video coding and decoding information required by video decoding is collected by a video App, wherein the video coding and decoding information is Mediacodecinfo information which is definition about a video data compression protocol, coding and decoding formats and the like (for example, the definition at least comprises a data format, a color format and the like). Android provides Mediacodec classes to facilitate developers to more flexibly process video coding and decoding, and compared with high-level APIs such as MediaPlayer/VideoView, Mediacodec is low-level APIs, so that it provides more complete, flexible and rich interfaces, and developers can realize more flexible functions. The MediaCodec class, which is part of the Android underlying video support infrastructure, can be used to access the Android underlying video codec (e.g., encoder/decoder components), from which MediaCodec information can be obtained for decoding of video.
102, generating a decoding strategy according to the video coding and decoding information, wherein the decoding strategy comprises each playing code rate supported by a current terminal and a mapping relation of a decoding type corresponding to each playing code rate, and the decoding type is determined by hardware information;
and the video App generates a decoding strategy based on a preset rule according to the collected video coding and decoding information. The generated decoding strategy comprises each playing code rate supported by the terminal and the mapping relation of the decoding type corresponding to each playing code rate. The playback bit rate, i.e. the bit rate, refers to the number of bits (bits) transmitted Per second, and the unit is bps (bit Per second), and the higher the bit rate is, the faster the data transmission speed is, and the higher the quality of the corresponding video is. Because the effect of hardware decoding is superior to that of software decoding, the preset rule when the decoding strategy is generated can be that high playing code rate is matched with hardware decoding or that hardware decoding and software decoding are matched simultaneously, and that low playing code rate is matched with software decoding. Such as: the supported play code rate is 40Mbps and 15Mbps according to the Mediacodeinfo information of the terminal A, wherein the decoding type corresponding to the play code rate of 40Mbps can be software decoding or hardware decoding, and the decoding type corresponding to the play code rate of 15Mbps can be software decoding. Since the decoding type is determined by hardware performance, the decoding type can be determined in advance by hardware information. Therefore, by means of the decoding strategy, on one hand, which play code rates are supported by the mobile terminal can be known, and on the other hand, the decoding type suitable for a certain play code rate can be known.
Certainly, in step 102, the video App may also upload the collected video coding and decoding information to an application server of the video App through a network protocol, and the application server generates a decoding policy according to a preset rule. In this case, the mobile terminal where the video App is located may also receive a notification message from the application server to confirm that the uploading of the video coding and decoding information is completed, and generate and store a flag information according to the notification message, so as to identify that the uploading of the video coding and decoding information is successful and avoid repeated uploading of the decoding information.
The server can issue the decoding strategy to each mobile terminal, for the mobile terminals with the same model and the same configuration, the server can generate the corresponding decoding strategy as long as the server collects the video coding and decoding information uploaded by any one terminal, the decoding strategy can be issued to each mobile terminal with the same model and the same configuration in batches, and each mobile terminal is not required to generate the decoding strategy locally.
103, analyzing the decoding strategy to select one of the playing code rates as a target playing code rate;
based on the generated decoding strategy, the video App can analyze the decoding strategy, and can obtain each playing code rate supported by the current mobile terminal through analysis, so that one playing code rate can be selected as a target playing code rate for video decoding.
And 104, determining a decoding type corresponding to the target playing code rate according to the mapping relation so as to decode the video.
When the target playing code rate of the video decoding is determined, the decoding type corresponding to the target playing code rate can be determined according to the mapping relation in the decoding strategy, and certainly, because the hardware decoding has the excellent characteristic that the workload of a CPU can be reduced, when the target playing code rate simultaneously corresponds to the hardware decoding and the software decoding, the hardware decoding is preferentially selected to ensure the video decoding effect. And the video App selects a proper decoder from the mobile terminal to decode the data stream related to the video according to the analyzed decoding strategy. Therefore, the decoding type is selected through the playing code rate, the decoding effect of the video is guaranteed, the decoding difference of terminals of different types is reduced, and the playing experience of a user is improved.
According to the video App decoding method provided by the invention, each playing code rate supported by the mobile terminal can be obtained according to the collected video coding and decoding information, one playing code rate and the corresponding decoding type are selected for decoding, an accurate and appropriate fine-grained decoding strategy can be provided for the video App, the decoding effect of the video can be ensured, the decoding difference of terminals of different types is reduced, the application range is wider, and the use experience of a user for playing the video can be improved.
Example two
Referring to fig. 2, a flowchart illustrating steps of a video App decoding method in the embodiment of the present invention is shown, and the specific steps include:
generally, a hardware product has its corresponding application manual, which specifies the usage instructions and performance parameters of the hardware product. The hardware information refers to parameter information of a CPU, a GPU and the like related to video decoding and playing, and is used for configuring the type and decoding type of the decoder, that is, for determining which type of the decoder is h.264avc, h.265hevc, VP8, VP9 and the like, and whether software decoding or hardware decoding is used. Based on the information, the invention can establish a hardware information configuration table in the video App and record the decoding types and the types of decoders supported by various types of hardware such as CPUs, GPUs and the like. The decoding type and the type of the decoder may be determined by collecting hardware information of the mobile terminal through the configuration table.
when the video App acquires the hardware information of the current terminal, the decoding type and the type of the decoder supported by the terminal can be determined by inquiring the hardware information configuration table. For example, it is known through table lookup that a GPU of a certain model supports a decoding type of hardware decoding, and supports a decoder of the h.265hevc type. Of course, in practice, it may happen that the terminal supports multiple decoder types (e.g., h.264avc, h.265hevc, VP8, VP9, etc.), and at this time, the type of the decoder is usually further determined according to the encoding mode of the played video slice source, which is not described herein again.
the operating systems of different versions generally indicate which additional video special effect functions are supported by the system, and the version information of the operating system can be collected and acquired through configuration files related to the operating system, so that the additional functions during video playing can be configured, and a user can experience the corresponding functions to control the playing of the video conveniently.
Step 204, controlling the display of additional function icons according to the operating system version information, wherein the additional functions at least comprise one or more of definition setting, VR setting and HDR setting;
after the version information of the operating system is collected, it can be known which additional functions are supported by the operating system of the current version, and the corresponding icons can be decoded and displayed on the player to set and control the functions according to the additional functions contained in the broadcast control information, where the additional functions may be one or more of definition setting, VR setting, and HDR setting, and of course, as the hardware performance is enhanced and the operating system functions are rich, the additional functions may also be expanded and increased, which is not limited in this invention.
in the invention, video coding and decoding information required by video decoding is collected by a video App, wherein the video coding and decoding information is Mediacodecinfo information which is definition about a video data compression protocol, coding and decoding formats and the like (for example, the definition at least comprises a data format, a color format and the like). Android provides Mediacodec classes to facilitate developers to more flexibly process video coding and decoding, and compared with high-level APIs such as MediaPlayer/VideoView, Mediacodec is low-level APIs, so that it provides more complete, flexible and rich interfaces, and developers can realize more flexible functions. The MediaCodec class, which is a part of the Android underlying video support infrastructure, can be used to access the Android underlying video codec (e.g., encoder/decoder components), from which video codec information can be obtained for decoding of video.
Step 206, generating a decoding strategy according to the video coding and decoding information, wherein the decoding strategy comprises mapping relationships between each playing code rate supported by a current terminal and a decoding type corresponding to each playing code rate, and the decoding type is determined by hardware information;
generating a decoding strategy according to the video coding and decoding information, wherein the decoding strategy comprises the following steps:
step 2061, obtaining a profile and a level through the video coding and decoding information;
video codec information is mediacodec info, which is a definition of a video data compression protocol, codec format, etc. (e.g., including at least definitions of a data format, a color format, etc.) of video, etc., and profile (profile) definitions are associated with characteristics, such as a compression algorithm, a chroma format, etc., and Level (Level) definitions are associated with performance, such as a maximum bit rate, a maximum frame size, etc. Thus, the profile and level may be obtained by the video codec information for decoding of the video.
Step 2062, obtaining each playing code rate supported by the mobile terminal according to the profile and the level;
taking the h.264avc video coding standard as an example, based on the information of the image coding type recorded in a profile (profile), if the image coding type is determined to be a key frame, an intra-frame prediction method is adopted for coding, otherwise, an inter-frame prediction method is adopted for motion estimation of the scene change situation, and the motion estimation value is actually a prediction value obtained by taking a currently coded video image frame as a reference image and performing motion compensation. Meanwhile, in order to reduce the prediction error and improve the compression ratio of the video image frame, the selection of the reference image can be obtained by reconstructing the video image frame which is coded in the past or in the future. And then, calculating the difference value between the predicted value and the current macro block to obtain residual macro block information, and then carrying out integer transformation, quantization, entropy coding and other processing on the residual macro block information. And finally, combining the bit rate obtained by coding with the information recorded in the Level to obtain each playing code rate supported by the mobile terminal. Therefore, each play code rate supported by the mobile terminal can be obtained according to the profile and the level.
Step 2063, adapting the corresponding decoding type for each playing code rate to generate a decoding strategy.
And the video App generates a decoding strategy based on a preset rule according to the collected video coding and decoding information. The generated decoding strategy comprises each playing code rate supported by the terminal and the mapping relation of the decoding type corresponding to each playing code rate. Since the decoding type is determined by hardware performance, the decoding type can be determined in advance by hardware information. Because the effect of hardware decoding is superior to that of software decoding, the preset rule when the decoding strategy is generated can be that high playing code rate is matched with hardware decoding or that hardware decoding and software decoding are matched simultaneously, and that low playing code rate is matched with software decoding. Specifically, a configuration file can be set according to the rule to record the corresponding relation between each playing code rate and the decoding type applied in the industry, and the configuration file is placed in the video App in advance, so that after each playing code rate supported by the mobile terminal is obtained according to a profile and a level, the video App can adapt to the corresponding decoding type for each playing code rate by inquiring the configuration file to generate a decoding strategy. Such as: the preset configuration file records 10Mbps corresponding software decoding, 15Mbps corresponding software decoding, 20Mbps corresponding software decoding, 40Mbps corresponding hardware decoding or software decoding, and the supported play code rate is 40Mbps and 15Mbps according to the Mediacodeinfo information of the A terminal, so that the configuration file shows that the decoding type corresponding to the play code rate of 40Mbps can be software decoding or hardware decoding, and the decoding type corresponding to the play code rate of 15Mbps can be software decoding.
Therefore, the generated decoding strategy includes mapping relationships between the various play code rates supported by the terminal and the decoding types corresponding to the various play code rates. Through the decoding strategy, on one hand, the playing code rates supported by the mobile terminal can be known, and on the other hand, the decoding type suitable for a certain playing code rate can be known.
based on the generated decoding strategy, the video App can analyze the decoding strategy, and can obtain each playing code rate supported by the current mobile terminal through analysis, so that one playing code rate can be selected as a target playing code rate for video decoding.
when the target playing code rate of the video decoding is determined, the decoding type corresponding to the target playing code rate can be determined according to the mapping relation in the decoding strategy, and certainly, because the hardware decoding has the excellent characteristic that the workload of a CPU can be reduced, when the target playing code rate simultaneously corresponds to the hardware decoding and the software decoding, the hardware decoding is preferentially selected to ensure the video decoding effect. Therefore, by selecting the decoding type corresponding to the target playing code rate, the accuracy and the fineness of the decoding strategy are ensured, the video decoding effect is improved, the decoding difference of terminals of different types is reduced, and the playing experience of a user can be improved.
And step 209, controlling video playing according to the version information of the operating system.
Based on the decoding of the video, the collected version information of the operating system can be used in the decoding and playing control process, and the version information of the operating system is also used for playing control in the decoding process, wherein the operating systems of different versions generally indicate which additional special effect functions are supported by the system, and the additional functions during the playing of the video can be configured through the version information of the operating system, so that a user can experience the corresponding functions to play and control the video, and the user can obtain rich function experience.
The video App decoding method provided by the invention can obtain the decoding type on the basis of hardware information, obtain each playing code rate supported by the mobile terminal according to the collected video coding and decoding information, select one as a target playing code rate, select the corresponding decoding type on the basis of the target playing code rate, and on the basis of the decoding type determined by the hardware information, the playing code rate from the video coding and decoding information is fused and considered, so that the coordination performance of software and hardware is fully exerted, the decoding strategy is more accurate, the system version information is utilized in the decoding process, the expansion of the decoding and playing control function is realized, and the use experience of a user is integrally improved.
