Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without inventive step, are intended to be within the scope of the present disclosure.

The following explains an application scenario of the embodiment of the present disclosure:

fig. 1 is an application scene diagram of a video continuous playing method provided by an embodiment of the present disclosure, where the video continuous playing method provided by the embodiment of the present disclosure may be applied to an application scene of splicing and continuously playing multiple video segments, and exemplarily, as shown in fig. 1, the method provided by the embodiment of the present disclosure may be applied to a terminal device, where three videos a, B, and C are cached in the terminal device, and the video a, the video B, and the video C may be three short videos formed by dividing a long video. More specifically, for example, the a video, the B video, and the C video respectively correspond to consecutive videos (e.g., a tv series) on three pieces of content, as shown in the figure, the a video is currently played, after the a video is played, the B video is automatically played, and the C video is played after the B video. However, each video segment includes a start interval (e.g., a start song portion) and an end interval (e.g., a trailer song portion), and the seamless switching between videos can be realized by accurately jumping and switching the start interval and the end interval of each video segment, so that three short videos, namely, a video a, a video B and a video C, which are continuously played, are a long video in the aspect of viewing and feeling.

In the actual playing process, in a scene of continuously playing multiple segments of videos, in the playing process of each segment of video, a corresponding decoder needs to be created to decode the video, however, in the prior art, a (software) decoder is created to decode the video only before playing the video, fig. 2 is a schematic diagram of continuously playing multiple segments of videos in the prior art, as shown in fig. 2, in the process of continuously playing a video a and a video B, before playing a video, a decoder a for decoding a video needs to be created first; after the video a is played, a decoder B required for decoding the video B needs to be created to decode the video B. Therefore, for a scene in which multiple segments of videos are continuously played, after the previous video is played, a decoder is created to decode the next video, which results in time consumption in processing, so that a gap between the two segments of videos is blocked, the impression of seamless switching between the multiple segments of videos cannot be formed, and the watching experience of a user is influenced. The embodiment of the present disclosure provides a method for continuously playing a video to solve the above problem.

Fig. 3 is a first schematic flow chart of a video continuous playing method according to an embodiment of the present disclosure. The method of the embodiment can be applied to terminal equipment, and the video continuous playing method comprises the following steps:

step S101, playing a first video based on a first decoder.

Illustratively, the first decoder is a decoder program created by a program call based on a multimedia framework for decompressing compressed video encoding data into pixel data for rendering playback at a terminal device. The multimedia framework is, for example, an ffmpeg framework, and in such a multimedia framework, various decoders for decoding different types of video encoded data are included, and a corresponding decoder is determined and created according to the type of video. In this embodiment, the first video is a playing video, and before the first video is played, the terminal device creates a first decoder matching the video type of the first video through the multimedia framework, and decodes and plays the first video based on the first decoder.

Specifically, the method for playing the first video based on the first decoder comprises the following steps: and decoding the first video based on a first decoder to generate video frames of the first video, and sequentially playing each video frame of the first video according to the playing time stamp corresponding to each video frame. The video frame of the first video is pixel data generated after decoding by the decoder. And playing the first video, which is actually a process that the terminal equipment plays video frames of the first video in sequence according to the playing time stamps.

Step S102, when the first video is played to the first target time stamp, a second decoder is created.

Illustratively, in the process of playing the first video according to the playing time stamp corresponding to each video frame in the first video, when the first video frame corresponding to the first target time stamp is played, the second decoder is created. Wherein the second decoder is a decoder program created by a program call based on the multimedia framework, similar to the first decoder. The second decoder is used for playing a second video to be played after the first video.

The purpose of creating the second decoder is to create a decoder for decoding the second video in advance, and avoid time consumption and pause caused by creating the decoder after the first video is played. Therefore, the second decoder needs to be created before the end of the first video playing, and the time point created by the second decoder is when the first video is played to the first target timestamp. The first target timestamp may be preset, for example, a playing timestamp corresponding to 90% of the total playing duration of the first video is determined as the first target timestamp, or a playing timestamp of the first video when 30 seconds remain is determined as the first target timestamp; or dynamically determined according to video information such as the video length and the video content of the first video.

Therefore, in this embodiment, before step S102, a step of determining the first target timestamp may also be included.

In one possible implementation, determining the first target timestamp includes: acquiring preset target remaining time, wherein the target remaining time is determined based on configuration parameters of terminal equipment; and determining a first target timestamp according to the target remaining time. Illustratively, the target remaining duration is a parameter characterizing the remaining playing duration of the first video, for example, 30 seconds, and the target remaining duration may be determined based on a configuration parameter preset by the terminal device.

In another possible implementation, determining the first target timestamp includes: and when the first video decoding is finished, determining a playing time stamp which is next to the playing time stamp of the currently played video frame as a first target time stamp.

Fig. 4 is a schematic diagram for determining a first target timestamp according to an embodiment of the present disclosure, and as shown in fig. 4, in a playing process of a first video, a terminal device decodes and plays the first video synchronously, where a progress of the decoding process is faster than a progress of the playing process, that is, a decoding position is closer to a terminal of the first video than the playing position. When the decoding process is completed, that is, when the decoding position reaches the end of the first video, the playing time stamp corresponding to the next position of the playing position at this moment is determined as the first target time stamp. That is, the creation of the second decoder is started immediately after the decoding process is finished. Therefore, the computing resources of the terminal equipment are fully utilized, and the efficiency is improved.

In another possible implementation, the first target timestamp may also be determined according to the number of key frame periods (GOPs) of the first video. The key frame period may also be referred to as a frame group, which is a frame set composed of an Instantaneous Decoding Refresh (IDR) frame and a series of P and B frames (of course, other I frames may be included in the key frame period). The larger the number of key frame periods, the lower the delay, the better the fluency and sharpness of the video, and correspondingly, the larger the amount of data due to the increased number of I frames. In a scenario of continuously playing multiple segments of video, it is considered that the second video needs to be pre-decoded after the second decoder is established, and the video quality (set by a user) of the continuously played first video and second video is generally consistent, so that the larger the number of key frame periods of the first video is, the more time the second decoder should be pre-decoded, and therefore, the earlier the first target timestamp should be. For example, for a first video with a total duration of 1 minute, when the number of key frame periods of the first video is 100, the first target timestamp is 50 seconds; when the number of key frame periods of the first video is 200, the first target timestamp is 40 seconds. In this embodiment, the first target timestamp is determined according to the number of the key frame periods of the first video, so that the pre-judgment of the time length required for pre-decoding the second video by the second decoder is realized, the time accuracy for creating the second decoder is improved, and the probability of pause between videos is further avoided.

Step S103, when the first video is played to a second target timestamp, playing a second video based on a second decoder, wherein the second target timestamp is located after the first target timestamp.

Illustratively, after the terminal device creates the second decoder, the second decoder is in a state to be called, and the process of creating the second decoder consumes certain computing resources and causes certain time consumption, but since the process of creating the second decoder is synchronous with the playing process of the first video, the user does not perceive the time consumption of the process and does not feel the video stuck. And then, when the first video is played to the second target timestamp, decoding the second video based on the second decoder in the to-be-called state, so that the second video can be played quickly, and seamless switching between the first video and the second video can be realized because time consumption caused by the creation of the second decoder is avoided.

The second target timestamp may be a playing timestamp corresponding to the last frame of the first video, that is, after the first video is completely played, the second video is played; or the playing time stamp of the preset playing position in the first video, for example, the playing time stamp of the end of piece position, that is, the end of piece position of the first video is played, and the second video is directly played, so that the continuity of the first video and the second video in the content is realized.

In one possible implementation, the second target timestamp includes:

in this embodiment, analyzing video content corresponding to a video frame of a first video to obtain video content information, where the video content information is used to represent a content category of the video frame of the first video; a second target timestamp is determined based on the video content information.

Specifically, in the process of playing the video frame of the first video, the terminal device analyzes each video frame, extracts the image characteristics, classifies the video content corresponding to the video frame based on the image characteristics, and determines the corresponding content category, that is, the video content information. Illustratively, the content category includes, for example, "normal video", "trailer", "advertisement", and the like. According to the obtained video content information, when the content type corresponding to the video content information is 'trailer', the playing time stamp corresponding to the next video frame at the current playing position is determined as a second target time stamp, namely when the content in the video frame is detected to be trailer, the second video is switched to be played, so that the purpose of skipping the trailer, the advertisement and other content at the end of the video is achieved, and the continuity of the first video and the second video in the content is achieved.

In the present embodiment, by being based on the first decoder, the first video is played; when the first video is played to a first target timestamp, a second decoder is established, wherein the first target timestamp is the playing timestamp of the first video frame; and when the first video is played to the second target timestamp, playing the second video based on the second decoder. Because the second decoder is created in advance when the first video is played to the first video frame before the end, when the first video is played, the second video can be directly decoded through the created second decoder without waiting for the creation of the decoder, so that the video switching interval blockage in the continuous playing process of the video segments can be reduced, and the switching smoothness of the video intervals in the continuous playing process of the video segments can be improved.

Fig. 5 is a schematic flowchart illustrating a second method for continuously playing video according to an embodiment of the present disclosure. In this embodiment, the step of predecoding the second video after creating the second decoder is described in detail, and the video continuous playing method includes:

step S201, decoding the first video based on the first decoder, and generating a video frame of the first video.

Step S202, according to the playing time stamp corresponding to each video frame, each video frame of the first video is played in sequence.

Step S203, when the first video decoding is completed, determining a playing time stamp subsequent to the playing time stamp of the currently played video frame as a first target time stamp.

Illustratively, in the process of playing the first video based on the first decoder, two processing links of decoding the first video and playing the first video are included. The two processing links can be asynchronously executed through different threads, for example, a first thread of the terminal device decodes a first video, generates a video frame and caches the video frame; and a second thread of the terminal equipment plays the cached video frame of the first video. Typically, the first thread is decoding the first video faster than the second thread is playing the video frames. In a possible implementation manner, in the process that the terminal device plays the first video through the first thread, when the first video is played to the first target timestamp, the terminal device creates a decoder through the second thread to prepare for subsequently decoding the second video; meanwhile, the first thread continues to play the first video. Since the second thread is a worker thread previously used to decode the first video, the first target timestamp is determined by the progress of the second thread in decoding the first video. More specifically, in a possible implementation manner, when the second thread completes decoding of the first video, a playing timestamp that is subsequent to a playing timestamp of a currently played video frame is determined as the first target timestamp, that is, after the second thread decoding process is completed, the second thread immediately starts to create the second decoder, and the first thread and the second thread are independent of each other.

Step S204, when the first video is played to the first target time stamp, a second decoder is created.

Step S205, obtaining a preset third target timestamp, and sequentially decoding, based on the second decoder, video frames before the second video frame corresponding to the third target timestamp in the second video to generate an intermediate frame.

Exemplarily, after the second decoder is created, if the corresponding video contents are continuous in the last interval of the first video and the start interval of the second video, the second video is directly played after the first video is played, that is, the second target timestamp of the first video corresponds to the last frame of the first video, and the continuity of the contents between the first video and the second video can also be achieved. However, in some cases, the end interval of the first video is not consecutive in content with the start interval of the second video, e.g., there is a beginning of a movie, an end of a movie, a short black screen; or there is an overlap in the content, after the first video is played to the second target timestamp, the second video is directly skipped to play (seek), for example, the beginning of the movie and the segment overlapping with the end interval of the first video are directly skipped, and the second video is played from the content connection position of the second video and the first video, that is, the video frame corresponding to the third target timestamp. The method for determining the third target timestamp may refer to the method for determining the second target timestamp, or may be determined based on a preset duration threshold, which is not described herein again. Fig. 6 is a schematic diagram of a third target timestamp provided in the embodiment of the present disclosure, and as shown in fig. 6, after the first video is played to the second target timestamp, the first video directly jumps to the third target timestamp position of the second video to be played, and jumps to a trailer of the first video (shown as a clip in the figure), a trailer of the second video (shown as B clip in the figure), and a content clip of the second video that overlaps with an end interval of the first video (shown as C clip in the figure), so as to implement uninterrupted playing of the first video and the second video. Wherein the video frames in the second video that are skipped without being played, i.e. are intermediate frames, such as the credits (B-clips) of the second video, and/or the content clips (C-clips) in the second video that repeat with the end interval of the first video.

Optionally, as shown in fig. 7, step S205 includes three specific implementation steps of steps S2051, S2052, and S2053:

step S2051 determines a key frame period in which the second video frame is located.

Step S2052 locates a key frame in the key frame period.

And step S2053, based on the second decoder, sequentially decoding from the position of the key frame until the previous video frame of the second video frame to generate an intermediate frame.

Illustratively, in this process, the intermediate frames in the second video do not need to be played, but based on the video decoding principle, the intermediate frames still need to be decoded in order to be able to normally play the second video frames. In the step of this embodiment, a method for determining an inter frame is provided, in which a key frame period where a second video frame is located is first located, then an IDR frame in the key frame period is determined, and video encoded data between the IDR frame and the second video frame are sequentially decoded to generate the inter frame, so that a decoder decodes the inter frame to the position of the second video frame. Fig. 8 is a schematic diagram of decoding a second video according to an embodiment of the present disclosure, and as shown in fig. 8, after a second decoder is created, a first thread of a terminal device still plays the first video, and meanwhile, a second thread of the terminal device determines a key frame period and an IDR frame corresponding to a second video frame, and invokes the second decoder in a state to be invoked, and starts decoding from the IDR frame until a previous video frame of the second video frame, so as to generate an intermediate frame. Illustratively, since the playing process of the first video and the decoding process of the second video are performed synchronously and independently, the decoding process of the intermediate frame is completed without perception of the user.

And step S206, when the first video is played to the second target time stamp, decoding and playing the second video from the second video frame based on the second decoder.

Illustratively, when the first video is played to the second target timestamp, the content to be played in the first video is played completely, and then the content is played from the second video frame (i.e. the video frame corresponding to the third target playing frame) of the second video through the second decoder, so as to realize the switching from the first video to the second video, so that the user is playing a continuous section of video without perceiving the process of video switching in the view of watching the video.

Specifically, the purpose of starting playing from the second video frame can be achieved in a manner of performing skip playing (seek) on the second video based on the second video frame. Fig. 9 is a schematic diagram of playing a second video starting from a second video frame, as shown in fig. 9, on the basis of the process of decoding the second video shown in fig. 8, when jumping and playing the second video are started, an IDR frame corresponding to the second video frame (i.e., an IDR frame that is before the second video frame and is closest to the second video frame) may be directly located, and then jumping to the position of the second video frame is performed, and decompressing and subsequently playing the second video frame. The method steps executed by the first thread and the second thread in the embodiments shown in fig. 8 and fig. 9 are only exemplary, and may be set according to specific use requirements, and are not limited herein.

In this embodiment, the implementation manner of step S204 is the same as the implementation manner of step S102 in the embodiment shown in fig. 3 of the present disclosure, and is not described again.
