Example 1
Fig. 1 is a flowchart of a video playing method according to a first embodiment of the present invention, where the method may be performed by a video playing device, and the video playing device may be implemented in hardware and/or software, and the video playing device may be configured in a computing device. As shown in fig. 1, the method includes:
s110, when a video switching request is received, obtaining video parameters of the current video to be played, corresponding to the video switching request.
The video switching request refers to an instruction and a code for requesting video switching. The video parameters include standard playing bandwidth and standard resolution. The video parameters correspond to the videos themselves, and the video parameters of each video may be different or the same.
In this embodiment, when the user triggers another video link control during browsing one video, the server may be considered to receive a video switching request, or when one video is played, the system automatically triggers a control for playing the next video, and at this time, the system is considered to receive the video switching request. The video corresponding to the trigger video link control can be used as the video to be played currently. After the system receives the video switching request, the system acquires the video parameters configured by the current video to be played.
In practical application, when video playing of some APP is processed, m3u8 format is usually adopted for playing, or h.264 and vp9 formats are usually adopted for playing, and before playing, a playing link of the video is usually acquired, so that video parameters of the video are acquired based on the playing link.
Optionally, obtaining the video parameters of the video to be played currently corresponding to the video switching request includes analyzing the video switching request to obtain a resource locator corresponding to the video to be played currently carried in the video switching request, obtaining a parameter file corresponding to the resource locator, and analyzing the parameter file to obtain the video parameters.
Wherein the resource locator is referred to as URL (uniform resource locator). The parameter file may be a file in m3u8 format.
Specifically, the URL, namely the resource locator, corresponding to the current video to be played, carried in the video switching request can be obtained by analyzing the video switching request. And further loads a parameter file corresponding to the resource locator. The video parameters such as standard playing bandwidth, standard resolution and the like contained in the parameter file can be obtained by analyzing the parameter file.
For example, after determining the URL (i.e. the resource locator), the corresponding m3u8 file may be downloaded through the URL, including two files, master.m3u8 and media.m3u8, where master.m3u8 is a parameter file, and the data format in the parameter file may be as follows:
#EXT-X-STREAM-INF:BANDWIDTH＝306568,CODECS＝"avc1.4D400C,mp4a.40.5",RESOLUTION＝426x240,AUDIO＝"233",FRAME-RATE＝25,VIDEO-RANGE＝SDR,CLOSE D-CAPTIONS＝NONE
The parameter file contains bandwidth value (i.e. standard playing bandwidth) 306568, coding mode (avc1.4D400C), resolution (i.e. standard resolution) 426x240, etc.
S120, determining the resolution to be used corresponding to the current video to be played based on the standard playing bandwidth and the historical playing bandwidth corresponding to the previous historical playing video.
The previous history playing video refers to the video played before switching, that is, the video played before the current video to be played.
It should be noted that, in the existing video playing mode, when each video is just started to play, the default bandwidth value is zero, then the actual bandwidth is monitored after 10 seconds after the video is played, and then the corresponding resolution is selected according to the actual bandwidth, so that the resolution is switched every time when one video is played, and the problem of poor playing effect exists because the lower resolution is adopted about 10 seconds before the video is just started to play. In order to better solve the problem, in this embodiment, after determining the video parameter of the current video to be played, a suitable resolution is selected for the current video to be played by combining the standard playing bandwidth in the video parameter and the historical playing bandwidth corresponding to the previous historical playing video, and at this time, the historical playing bandwidth is closest to the network bandwidth loading the current video to be played at the current moment, so that the playing condition of the current video to be played can be well satisfied, and the situation that video is blocked or the video is unclear when the current video to be played starts to be played is prevented.
Specifically, the method comprises the steps of determining the resolution to be used corresponding to the current video to be played based on the standard playing bandwidth and the historical playing bandwidth corresponding to the previous historical playing video, wherein if the standard playing bandwidth is smaller than the historical playing bandwidth corresponding to the previous historical playing video, the standard resolution is used as the resolution to be used of the current video to be played.
In this embodiment, the standard playing bandwidth and the historical playing bandwidth corresponding to the previous historical playing video may be compared, if the standard playing bandwidth is smaller than the historical playing bandwidth, it may be stated that if the current video to be played is played with the standard resolution at the current moment, no play jam will occur, the playing condition of the current video to be played is satisfied, the resolution does not need to be adjusted, and the standard resolution in the video parameter may be used as the resolution to be used of the current video to be played, so that the current video to be played is played based on the resolution to be used.
In the actual playing process, how to detect that the historical playing bandwidth is not greater than the standard playing bandwidth 306568 is exemplified, the standard resolution is directly used for playing, and if the standard playing bandwidth is higher, the resolution corresponding to the historical playing bandwidth is selected for playing.
In the embodiment, the method comprises the steps of determining the resolution to be used corresponding to the current video to be played based on the standard playing bandwidth and the historical playing bandwidth corresponding to the previous historical playing video, determining the resolution to be applied corresponding to the historical playing bandwidth if the standard playing bandwidth is larger than the historical playing bandwidth corresponding to the previous historical playing video, and taking the resolution to be applied as the resolution to be used of the current video to be played.
Specifically, if the standard playing bandwidth is greater than the historical playing bandwidth, it may be stated that if the current video to be played is played at the standard resolution at the current moment, a phenomenon of playing jam may occur, and the resolution needs to be adjusted. The resolution to be applied may be regarded as the resolution to be used. So that the current video to be played is played based on the resolution to be used, and the video playing fluency is improved.
And S130, playing the current video to be played based on the resolution to be used, and determining the current playing bandwidth when the current video to be played is played as the historical playing bandwidth, so that when the video switching request is received again, the resolution to be used corresponding to the next video to be played is determined based on the historical playing bandwidth and the standard playing bandwidth of the next video to be played.
In this embodiment, in the process of playing the current video to be played based on the resolution to be used, the current playing bandwidth during playing may be monitored in real time, the current playing bandwidth may change along with the playing middle of the video, and when the new real-time playing bandwidth is detected, the playing bandwidth recorded last time may be updated based on the time dimension, so that when the playing of the current video to be played is finished, the detected current playing bandwidth is the closest to the next switching video, that is, the switching time of the next video to be played is the closest. The current playing bandwidth can be used as the historical playing bandwidth, when the video switching request is received again next time, the resolution to be used corresponding to the video to be played next time can be determined based on the historical playing bandwidth and the standard playing bandwidth of the video to be played next time, and the playing effect of each video is improved in the process of playing the video stream.
It should be noted that, in the process of determining the current playing bandwidth when the current video to be played is played, the current playing network speed when the current video to be played is played can be determined, and the current playing bandwidth is determined based on the current playing network speed.
In this embodiment, the current playing network speed may be monitored in real time during the process of playing the current video to be played, and further, the current playing network speed may be converted into the network bandwidth, so as to obtain the current playing bandwidth.
In order to better meet the viewing experience of the user, a switching prompt can be given in the video switching process. Optionally, when receiving the video switching request, a video switching prompt message may be generated and displayed.
Specifically, when a video switching request is received, it is considered that video switching is performed at this time, a menu prompt may be added, and video switching prompt information is displayed in a switching area, and exemplary video switching prompt information may be "currently switching". It should be noted that the switching area may be any area of the display interface, and may be determined by a technician according to an actual working condition, which is not limited herein.
According to the technical scheme, when a video switching request is received, standard playing bandwidth and standard resolution of a current video to be played corresponding to the video switching request are obtained, the resolution to be used corresponding to the current video to be played is determined based on the standard playing bandwidth and the historical playing bandwidth corresponding to the previous historical playing video, the current video to be played is played based on the resolution to be used, the current playing bandwidth when the current video to be played is determined to serve as the historical playing bandwidth, when the video switching request is received again, the resolution to be used corresponding to the next video to be played is determined based on the historical playing bandwidth and the standard playing bandwidth of the next video to be played, the problem that viewing experience of a user is affected due to the fact that the video resolution is manually adjusted by a user in the prior art is solved, the fact that the standard playing bandwidth of the current video to be played is determined when the video is switched, the historical playing bandwidth corresponding to the previous historical playing video is comprehensively considered, the current video to be the best suitable for the resolution to be used is determined, the current video to be played based on the resolution to be used is played, the effect of the video to be played is improved, and further, the viewing experience of the user is improved, and the technical effect of the user is achieved.
Example two
As an alternative embodiment of the foregoing embodiment, a specific application scenario example is given to make the technical solution of the embodiment of the present invention further clear to those skilled in the art. In particular, reference may be made to the following details.
For example, referring to fig. 2, fig. 2 may be represented as a schematic diagram of a video playing method, when playing video using an APP, a current network speed may be recorded after playing a first film source, and a corresponding bandwidth value is obtained, and if no network speed is detected, it is indicated that no network exists, and the video playing method is in a network card state. When video switching is performed, gstframework layers need to throw out messages to upper layers, the first message represents that resolution switching is ready at present, and the second message throws out the bandwidth value detected for the first time to the upper layer APP. After the upper layer receives the resolution switching information, then the menu is prompted, namely the menu is increased when the video is switched, the bandwidth value is recorded, then the bandwidth is set when the pipeline is constructed, the bandwidth of the first video is played again when the second video is played again, and the most suitable resolution is directly selected and the resolution is not switched, so that the requirement of a user can be met. The corresponding url can be obtained based on the video link through the system, and then the corresponding m3u8 file is downloaded through the url, wherein the m3u8 file comprises master.m3u8 (i.e. parameter file) and media.m3u8 (code stream fragment file). For example, the parameter file content may be
#EXT-X-STREAM-INF:BANDWIDTH＝306568,CODECS＝"avc1.4D400C,mp4a.40.5",RESOLUTION＝426x240,AUDIO＝"233",FRAME-RATE＝25,VIDEO-RANGE＝SDR,CLOSE D-CAPTIONS＝NONE, The parameter file contains bandwidth value (i.e. standard playing bandwidth) 306568, coding mode (avc1.4D400C), resolution (i.e. standard resolution) 426x240, etc. In the actual playing process, how to detect that the historical playing bandwidth corresponding to the last historical playing video is larger than 306568 is directly used for playing 426x240, and if the standard playing bandwidth is higher, the most suitable link is selected for playing. And then through the corresponding link, the m3u8 file corresponding to the actual code stream can be downloaded, and the file contains the actual code stream fragment. It should be noted that, because the upper layer directly performs the network speed transfer, the function gst_hls_master_playlist_get_variant_for_bitrate(hlsdemux->master,NULL,demux->connection_speed) is directly executed, so that the resolution is not required to be switched, and the video playing effect is improved.
According to the technical scheme, when a video switching request is received, standard playing bandwidth and standard resolution of a current video to be played corresponding to the video switching request are obtained, the resolution to be used corresponding to the current video to be played is determined based on the standard playing bandwidth and the historical playing bandwidth corresponding to the previous historical playing video, the current video to be played is played based on the resolution to be used, the current playing bandwidth when the current video to be played is determined to serve as the historical playing bandwidth, when the video switching request is received again, the resolution to be used corresponding to the next video to be played is determined based on the historical playing bandwidth and the standard playing bandwidth of the next video to be played, the problem that viewing experience of a user is affected due to the fact that the video resolution is manually adjusted by a user in the prior art is solved, the fact that the standard playing bandwidth of the current video to be played is determined when the video is switched, the historical playing bandwidth corresponding to the previous historical playing video is comprehensively considered, the current video to be the best suitable for the resolution to be used is determined, the current video to be played based on the resolution to be used is played, the effect of the video to be played is improved, and further, the viewing experience of the user is improved, and the technical effect of the user is achieved.
