Description
Technical Field
The present invention relates to decoding technologies, and in particular, to a video decoding method and apparatus.
Background
With the development and popularization of smart phones, users watch videos with mobile phone players increasingly frequently. After the user downloads the video to be watched into the smart phone, the smart phone decodes the downloaded video and then can smoothly play the video. In the prior art, there are mainly two video decoding methods: a hardware-based decoding method and a software-based decoding method are described below.
Current smartphones are typically equipped with a system decoder, i.e., a hard decoder as described below. Different chip models of smart phones may include different hard decoders, where a hard decoder includes a plurality of different hardware decoding elements, where the different hardware decoding elements include different hardware decoding elements, and each hardware decoding element may be used to decode a format of video. The hard decoder has higher decoding speed, but is limited by the type and the number of hardware decoding elements, and one hard decoder can only decode videos in fixed formats, for example, for the hard decoder of an android system smart phone, only video files in mp4 and 3gp formats are supported.
The soft decoder is hardware independent, the hard decoder decodes video at the physical layer, and the soft decoder is used to decode video using decoding techniques at the application layer. There are many kinds of soft decoders on the market currently, there is a corresponding soft decoder for each video format, and as long as the soft decoder supporting the corresponding video format is installed on the smart phone, the video in the format can be decoded, so that the soft decoder has a relatively flexible applicability. However, the instructions of the soft decoder guarantee the compatibility of the smart phones with different chip models in a mode of sacrificing efficiency when the instructions are operated, so the operation speed of the soft decoder is not high.
The smart phone system in the current market is provided with a hard decoder and one or more soft decoders, when a user needs to decode a downloaded video, the smart phone system provides two options for the user, wherein one option is used for indicating that the hard decoder is selected, the other option is used for indicating that the soft decoder is selected, if the hard decoder is selected by the user, the smart phone system calls the hard decoder to decode, and if the soft decoder is selected by the user, the smart phone system calls the corresponding soft decoder to decode after recognizing the format of the video to be played. If the smart phone system does not have the soft decoder corresponding to the format of the video to be played, the smart phone also needs to send a request to the server in a wireless networking mode to request the soft decoder corresponding to the format, the server stores the soft decoders corresponding to each different video format one by one in advance, after receiving the request sent by the smart phone, the server sends the soft decoder corresponding to the format to the smart phone, namely the smart phone downloads the soft decoder corresponding to the format, and then the smart phone system calls the soft decoder to decode.
It can be seen that, in the prior art, the user selects the decoder to decode the video to be played by a manual method, and since the user does not know the format of the video to be played, the format supported by the hard decoder and the format supported by each soft decoder, the user selects the decoder by a manual method is a completely blind behavior. This blind behavior may result in multiple repeated selections, for example, if the video to be played is in a format supported by a soft decoder, the user blindly selects a hard decoder that does not support the format, resulting in a decoding failure, and then the user must re-select the soft decoder among the options. Such blind selection may also result in a failure to select an optimal decoder for the video, for example, if the video to be played is in a format supported by a hard decoder with a faster decoding rate, the user blindly selects a soft decoder with a slower decoding rate that also supports this format, resulting in a longer decoding time for the video. In summary, in the prior art, a method for decoding a video to be played by selecting a decoder manually by a user has certain blindness, and a correct and optimal decoder may not be selected for the video, so that the user repeatedly selects the video for many times or the decoding time is long, thereby reducing the user experience.

The method for updating the server-side chip capability table in the server comprises the following steps: and storing the name of the new soft decoder and the video format supported by the new soft decoder in the server-side chip capability table, and deleting the name of the soft decoder supporting the same video format and the video format supported by the soft decoder from the server-side chip capability table.
Meanwhile, when a more efficient new soft decoder appears, the server can also actively recommend the mobile phone, and the specific method comprises the following steps: the server sends a notification message to the mobile phone, wherein the notification message carries the name of the new soft decoder and the video format supported by the new soft decoder, if the mobile phone returns a confirmation message to the server, the server sends the new soft decoder to the mobile phone, and the mobile phone updates the soft decoder and the mobile phone end chip capability table stored in the mobile phone. The method for updating the soft decoder stored in the mobile phone comprises the following steps: the new soft decoder is stored in the handset and the soft decoders in the handset and the new soft decoder supporting the same video format are deleted. The method for updating the mobile phone terminal chip capability table comprises the following steps: and storing the name of the new soft decoder and the video format supported by the new soft decoder in the mobile phone end chip capability table, and deleting the name of the soft decoder supporting the same video format and the video format supported by the soft decoder from the mobile phone end chip capability table. Of course, if the mobile phone does not return an acknowledgement message or a rejection message to the server, the soft decoder and the mobile phone end chip capability table in the mobile phone are not updated.
