In the related art, in order to solve the problem that the waiting time is long in the video data starting process, the currently mainly adopted method includes:
1. the hardware decoder is preferentially used, and the video data decoding time length is shortened by utilizing the characteristic that the work performance is good. However, when compatibility of the video code stream and the hardware decoder is in problem, the hardware decoder resource is released, and then a software decoder is created to decode the video data again. However, the creation of the software decoder inevitably requires reloading, parsing, and the like of the video data. The user can only wait for the software decoder to be ready. Affecting the user experience.
2. A smooth stream switching technique is used. Namely, the electronic equipment selects the low-bit-rate video resource of the same video stored in the server to play in the starting process. And after the video starts to be played, selecting the opportunity to switch to the video source of the normal code stream. In this way, the effect of accelerating the picture output is achieved. However, this approach requires server-side intervention to provide the same video multi-rate resource. Meanwhile, the electronic equipment itself needs to perform corresponding processing aiming at smooth code stream switching.

First embodiment
Referring to fig. 2, fig. 2 is a flowchart of a start-up acceleration method according to a preferred embodiment of the present invention. The starting acceleration method can be applied to the electronic device 100 and is used for improving the image output efficiency of the video data in the starting process of the electronic device 100. The broadcast starting acceleration method comprises the following steps:
step S101, sending the decapsulated video stream to the processing queue of the hardware decoder 115 and the processing queue of the software decoder, respectively.
In the embodiment of the present invention, after receiving the video data to be played, the electronic device 100 performs decapsulation processing on the video data to obtain a video stream and an audio stream. Specifically, in the decapsulation process, a video stream and an audio stream of the video data are identified and split.
Further, the video stream is respectively put into the processing queue of the hardware decoder 115 and the processing queue of the software decoder, and the hardware decoder 115 and the software decoder are started to decode the video stream simultaneously. It should be noted that the processing queue may be a (First Input First Output, FIFO) queue, so that the decoder performs decoding processing on each frame of image data of the video stream in sequence.
Step S102, when the software decoder decodes the first I frame data of the video stream, the first I frame data is output and displayed through the display unit 114.
In the embodiment of the invention, the software decoder has excellent compatibility to the format and flexibility of decoding, and can quickly determine the decoding mode compatible with the format of the video stream in the process of decoding the video stream. And because it can quickly determine the decoding mode compatible with the video stream format, the software decoder can decode the first I frame data of the video stream faster than the hardware decoder 115. After the first I frame data is decoded by the software decoder, the first I frame data is output and displayed through the display unit 114, so that the first I frame data of the display video stream is output before the hardware decoder 115 successfully decodes the video stream, and the efficiency of image output is improved. The time for the user to wait for the video data to be played is relieved, and the watching experience is improved. It should be noted that, in the related art, the decoding of the video stream is usually required to be completed for the output display of the video data, but in this embodiment, after the software decoder decodes the first I frame data, the software decoder forces to output and display the decoded I frame data and the display unit 114 performs the output display. That is, the first picture can be output and displayed earlier than the manner of starting in the related art under the same external conditions.
Alternatively, the step of outputting the first I frame data obtained by decoding the display may be:
(1) And obtaining the YUV data corresponding to the first I frame data decoded by the software decoder. Specifically, the first I frame data may be transmitted into a null BUFFER, and then the corresponding YUV data may be refreshed. It should be noted that YUV is a color coding method. Are often used in various video processing components. YUV allows for reduced bandwidth of chrominance in view of human perception when encoding photos or videos.
(2) And processing the YUV data of the first I frame data according to the requirement parameters of the electronic device 100. Optionally, the required parameters of the electronic device 100 may be a supported format, a size, a screen angle, and the like of a playing platform in the electronic device 100. Correspondingly, the YUV data processing may be format adjustment, cropping, screen rotation, and the like.
(3) And calling a rendering interface of the display unit 114 to output and display the processed YUV data.
Step S103, if the video stream decoded by the hardware decoder 115 is obtained within a preset time, playing the multimedia data generated based on the video stream decoded by the hardware decoder 115.
In the embodiment of the present invention, step S102 and step S103 are parallel steps, and there is no specific sequence between them. When the electronic device 100 actually performs the start-up acceleration method provided by the embodiment of the present invention, step S102 is usually triggered before step S103 due to the time difference between the decoding of the first frame I frame data and the decoding of the video stream.
In the embodiment of the present invention, as the hardware decoder 115 is improved, the supported media formats are more and more abundant, though limited, and it is a preferred solution for decoding video stream with very low power consumption and good stability. The hardware decoder 115 decodes the video stream faster than the software decoder. Therefore, the electronic device 100 preferably selects the video stream decoded by the hardware decoder 115 to generate video data for playback. Alternatively, when the hardware decoder 115 completes decoding the video stream for a preset time, the multimedia data may be generated based on the video stream decoded by the hardware decoder 115. Alternatively, the preset time may be a time period for the hardware decoder 115 to complete decoding of the video stream normally. That is, if the decoding duration of the hardware decoder 115 is within the preset time and the hardware decoder 115 does not generate the decoding failure signal, it can be considered that the hardware decoder 115 is still running normally, and can continue to wait for it to decode the video stream. If the decoding time of the hardware decoder 115 exceeds a preset time or an error indication is generated, it is confirmed that the hardware decoder 115 fails to decode.
Further, after the video stream decoded by the hardware decoder 115 is obtained within the preset time, the flow proceeds to step S104.
And step S104, closing the software decoder.
In the embodiment of the invention, after the software decoder decodes and outputs and displays the first frame of I frame data, the video stream can be continuously decoded according to a normal mode. However, once the hardware decoder 115 decodes the video stream within the preset time, the software decoder is not needed to continue decoding the video stream at this time. Therefore, the software decoder is turned off to release the system resources occupied by the software decoder, thereby saving the system resources and improving the operation efficiency of the whole electronic device 100.
Further, in order to avoid the incompatibility of the hardware decoder 115 with the format of the video stream, repeatedly enabling the hardware decoder 115 to decode results in a waste of decoding time. As shown in fig. 3, the start-up acceleration method provided in the embodiment of the present invention may further include:
step S105, if the video stream decoded by the hardware decoder 115 is not obtained or the decoding failure signal generated by the hardware decoder 115 is obtained within the preset time, playing the multimedia data generated based on the video stream decoded by the software decoder.
In the embodiment of the present invention, step S103 and step S105 have no necessary sequence, but both of them are in parallel. It should be noted that, if the hardware decoder 115 does not decode the video stream within the preset time or generates a decoding failure signal during the decoding process, it means that the hardware decoder 115 fails to decode. Since the software decoder and the hardware decoder 115 decode the video stream at the same time, and the software decoder will continue to decode the video stream normally after decoding the first I frame data. Therefore, after confirming that the hardware decoder 115 fails to decode the video stream, the hardware decoder 115 can smoothly switch to the software decoder, acquire the video stream decoded by the software decoder, and generate the multimedia data for playing. Compared with the related art, the software decoder is newly created after the hardware decoder 115 fails to decode the video stream is determined, and the newly created software decoder restarts decoding of the video stream, so that compared with the scheme provided by the related art, the method provided by the embodiment of the invention can save a large amount of waiting time. The phenomenon of pause caused by switching between the soft decoder and the hard decoder is avoided, and the watching experience of a user is prevented from being influenced.
Further, in order to obtain multimedia data generated based on the decoded video stream, as shown in fig. 4, before playing the multimedia data, the method further includes:
step S201, performing audio decoding on the decapsulated audio stream.
In the embodiment of the present invention, a software decoder may be used to perform audio decoding on the audio stream after being decapsulated.
Step S202, adjusting the audio stream according to the requirement parameter of the electronic device 100.
In the embodiment of the present invention, the requirement parameter may be a support requirement parameter of a platform installed in the electronic device 100 for playing video data, and for example, the support requirement parameter may include a support format, a channel, a playing rate, and the like. And correspondingly adjusts the audio stream accordingly so that the audio stream can be played.
Step S203, when the hardware decoder 115 decodes the video stream within a preset time, generating the multimedia data according to the adjusted audio stream and the video stream decoded by the hardware decoder 115.
In the embodiment of the present invention, the video stream decoded by the hardware decoder 115 may be processed based on the requirement parameter. Optionally, the required parameters of the electronic device 100 may be a supported format, a size, a screen angle, and the like of a playing platform in the electronic device 100. Correspondingly, the processing of the video stream decoded by the hardware decoder 115 may be supporting format adjustment, cropping, picture rotation, and the like.
And synchronizing the adjusted audio stream with the processed video stream to generate the multimedia data.
Step S204, when the hardware decoder 115 does not decode the video stream within a preset time or obtains a decoding failure signal generated by the hardware decoder 115, generating the multimedia data according to the adjusted audio stream and the video stream decoded by the software decoder.
In the embodiment of the present invention, the video stream decoded by the software decoder may be processed based on the requirement parameter. Optionally, the required parameters of the electronic device 100 may be a supported format, a size, a screen angle, and the like of a playing platform in the electronic device 100. Correspondingly, the processing of the video stream decoded by the software decoder may be supporting format adjustment, cropping, picture rotation, and the like.
And synchronizing the adjusted audio stream with the processed video stream to generate the multimedia data.
