The Memory 1005 may be a Random Access Memory (RAM) Memory or a non-volatile Memory (e.g., a magnetic disk Memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
It will be appreciated by a person skilled in the art that the device structure shown in fig. 1 does not constitute a limitation of the video data encoding device and may comprise more or less components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a video data encoding program.
In the video data encoding apparatus shown in fig. 1, the network interface 1004 is mainly used for connecting an external network and performing data communication with other network apparatuses; the user interface 1003 is mainly used for connecting to a user equipment and performing data communication with the user equipment; the apparatus of the present invention calls a video data encoding program stored in the memory 1005 through the processor 1001 and performs the video data encoding method provided by the embodiment of the present invention.
Based on the above hardware structure, an embodiment of the video data encoding method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a video data encoding method according to a first embodiment of the invention.
In a first embodiment, the video data encoding method comprises the steps of:
step S10, device performance and current network status are detected.
It should be noted that, the execution main body of this embodiment may be a video data encoding device, and may also be other devices that can implement the same or similar functions, which is not limited in this embodiment, and the video data encoding device may be a main broadcasting device, for example, a terminal device that can be used for live broadcasting, such as a mobile phone, a tablet, a computer, and the like, and may also be other devices, which is not limited in this embodiment.
It should be understood that the mode of detecting the device performance by the anchor device may be to acquire device information, determine the device performance according to the device information, or may be other modes, which is not limited in this embodiment.
It should be understood that the current network status includes the status of a mobile network, a wireless network, a wired network, etc., and since the anchor obviously needs to connect to the network during the live broadcast, the status without network connection is not considered in this embodiment.
It can be understood that, when the live broadcast device used by the anchor is a mobile terminal device such as a mobile phone and a tablet, the current network state of the mobile terminal may be a wireless network or a mobile network; when the live broadcast device used by the anchor is a computer, the current network state of the computer can be a wireless network or a wired network.
It should be noted that, because the live broadcast is a continuous process, and the current network state may change in the live broadcast process, the detection process is also a continuous detection process, and may be periodic detection according to a preset period or timing detection, so as to determine an appropriate target encoding policy according to the device state of the current live broadcast device.
Step S20, determining a corresponding target coding policy according to the device performance and the current network state.
It should be noted that, a corresponding target coding policy may be determined according to the device performance and the current network state, where the target coding policy includes a multi-path coding policy and a single-path coding policy, the multi-path coding policy is to code a video to be coded into videos of different coding formats, and the single-path coding policy is to code a video to be coded into a video of a single coding format, specifically, the multi-path coding policy may code a video to be coded into videos of an h.265 coding format and an h.264 coding format, and the single-path coding policy is to code a video to be coded into a video of an h.265 coding format or an h.264 coding format.
It should be understood that the one-way encoding strategy includes a first one-way encoding strategy corresponding to the h.265 encoding format and a second one-way encoding strategy corresponding to the h.264 encoding format.
And step S30, when the target coding strategy is a multi-channel coding strategy, coding the video data to be coded according to different coding formats to obtain multi-channel coded video.
It should be understood that, when the target encoding strategy is a multi-path encoding strategy, the video data to be encoded is encoded according to the h.265 encoding format and the h.264 encoding format, so as to obtain encoded videos of the two encoding formats, and the encoded videos according to the two encoding formats form a multi-path encoded video.
Further, after the step S20, the method further includes:
when the target coding strategy is a one-way coding strategy, searching a one-way coding format corresponding to the one-way coding strategy; coding the video data to be coded according to the single-channel coding format to obtain a single-channel coded video; and pushing the single-path coded video to a video receiving device.
It should be noted that the target encoding strategy may be a multi-path encoding strategy, but also a single-path encoding strategy, and only when the device performance and the current network state cannot satisfy the multi-path encoding strategy, the single-path encoding strategy is adopted for video encoding, that is, the multi-path encoding strategy is preferentially selected, and when the multi-path encoding strategy cannot be used, the single-path encoding strategy is adopted.
It should be understood that the one-way encoding strategy is further divided into a first one-way encoding strategy and a second one-way encoding strategy, wherein the encoding format corresponding to the first one-way encoding strategy is the h.265 encoding format, and the encoding format corresponding to the second one-way encoding strategy is the h.264 encoding format.
It should be understood that, when the target encoding strategy is the first one-way encoding format, encoding the video data to be encoded according to the h.265 encoding format to obtain a one-way encoded video; and when the target coding strategy is in the second one-way coding format, coding the video data to be coded according to the H.264 coding format to obtain the one-way coded video.
It can be understood that, under the condition of the one-way encoding policy, only the video data to be encoded is encoded according to one encoding format, and the generated one-way encoded video is an encoded video with a single format, so that when the one-way encoded video is pushed to the video receiving device, the video receiving device cannot select and can only receive the one-way encoded video with the encoding format.
In a specific implementation, for example, when the target encoding policy is the first one-way encoding policy, encoding video data to be encoded according to the h.265 encoding format to obtain a one-way encoded video in the h.265 encoding format, and pushing the video to the video receiving device for playing, whereas if the video receiving device does not support playing of the video in the h.265 encoding format, or the user does not want to watch the video in the h.265 encoding format, the server needs to transcode the one-way encoded video into the video in the h.264 encoding format, and then push the video to the video receiving device for playing.
And step S40, pushing the multi-channel coded video to a video receiving device.
It should be noted that, multiple paths of encoded videos with different encoding formats are pushed to the video receiving device, and the video receiving device may select an encoded video with one encoding format from the multiple paths of encoded videos to play, for example, the multiple paths of encoded videos include an encoded video with an h.265 encoding format and an encoded video with an h.264 encoding format, and the video receiving device may select the encoded video with the h.265 encoding format to play and also select the encoded video with the h.264 encoding format to play, so that the selectivity of a user in watching a live broadcast is increased, and the comfort of the user in watching the live broadcast is further improved.
Further, the step S40 includes:
packaging the multi-path coded video to obtain a multi-path coded video packet; and uploading the multi-path coded video packets to a server so that the video receiving equipment selects the coded video with the corresponding coding format to download according to the multi-path coded video packets in the server.
It can be understood that the multiple paths of coded videos include coded videos of two coding formats, the multiple paths of coded videos are packaged into multiple paths of coded video packages, and the multiple paths of coded video packages are uploaded to a server, when a user watches live broadcasting through a video receiving device, the user can select to watch coded videos of an H.265 coding format or coded videos of an H.264 coding format, the video receiving device can select coded videos of a coding format corresponding to user requirements from the multiple paths of coded video packages to download and play, and therefore the watching requirements of the user can be met under the condition that transcoding is not carried out through the server.
In the embodiment, the performance of the equipment and the current network state are detected; determining a corresponding target coding strategy according to the equipment performance and the current network state; when the target coding strategy is a multi-channel coding strategy, coding video data to be coded according to different coding formats to obtain multi-channel coded videos; and pushing the multi-path coded video to a video receiving device. Therefore, under the condition that the equipment performance and the current network state meet the conditions, the video data to be coded are coded into multiple paths of coded videos according to different coding formats and are pushed to the video receiving equipment, and the video receiving equipment selects one of the coded videos to play, so that the equipment performance of the main broadcasting equipment is effectively utilized, and the transcoding cost of a server side is saved.
In an embodiment, as shown in fig. 3, based on the first embodiment, a second embodiment of the video data encoding method of the present invention is provided, where the video data to be encoded is anchor video data, and the step S20 includes:
step S201, determining whether a preset encoding format is supported according to the device performance.
It should be noted that the video data to be encoded is anchor video data, and the anchor video data may be screen interface video data and/or camera video data, for example, when the anchor device is a mobile phone, the anchor video data may be mobile phone screen interface data, camera video data of a front camera, camera video data of a rear camera, and other video data, which is not limited in this embodiment.
It should be noted that the preset encoding format is an h.265 encoding format, because the multi-path encoding policy in this embodiment encodes the video data to be encoded according to the h.265 encoding format and the h.264 encoding format to obtain the multi-path encoded video, and the h.264 encoding format is a relatively mature encoding format, which can basically be supported by the terminal, it needs to be determined whether the h.265 encoding format is supported, which is a preliminary determination, and only when the preset encoding format is supported, a subsequent further determination is performed, if the preset encoding format is not supported, it is determined that the multi-path encoding policy cannot be used for encoding, and the second single-path encoding policy is used as the target encoding policy.
Step S202, if the preset coding format is supported, acquiring anchor account information, and determining the anchor level according to the anchor account information.
It should be understood that, if the preset encoding format is supported, the anchor account information is obtained, and the anchor level is determined according to the anchor account information, in this embodiment, the anchor account level may be divided into an a-anchor and an a + anchor, and a audience group of the a-anchor is not large as an audience group of the a + anchor, so that it is necessary to further determine whether the audience number reaches the standard for the a-anchor, and it is not necessary to determine the audience number for the a + anchor, and other level divisions may also be performed, which is not limited in this embodiment.
Step S203, determining a corresponding target coding strategy according to the anchor grade, the equipment performance and the current network state.
Further, the step S203 includes:
judging whether the anchor grade is greater than a preset grade or not; if the anchor grade is greater than the preset grade, judging whether the equipment performance exceeds the preset performance; if the equipment performance exceeds the preset performance, judging whether the current network state is a mobile network; and if the current network state is not the mobile network, selecting a multi-channel video coding strategy from preset coding strategies as a target coding strategy.
In a specific implementation, when the anchor level is divided into a-anchor and a + anchor, the preset level may be set to a, and if greater than the preset level, the a + anchor is determined, and if less than the preset level, the a-anchor is determined.
It should be understood that if the anchor level is greater than the preset level, it is determined whether the device performance exceeds the preset performance, the preset performance may be set by a technician according to an actual situation, a performance standard is set, and when the performance standard is exceeded, a multi-path coding strategy is adopted; when the performance standard is not met, a one-way coding strategy is adopted.
It can be understood that if the device performance exceeds the preset performance, it is further necessary to determine whether the current network state is a mobile network, if the current network state is a mobile network, a one-way encoding policy is adopted, and if the current network state is not a mobile network, that is, a wired network or a wireless network, a target encoding policy is selected from the multi-way video encoding policies.
It can be understood that, when the current network state is a wired network or a wireless network, the current network strength can also be acquired, and when the network strength is poor, the one-way video coding strategy is used as the target coding strategy.
It should be noted that the preset encoding strategy includes a multi-channel video encoding strategy and a single-channel video encoding strategy, where the single-channel encoding strategy is further divided into a first single-channel encoding strategy and a second single-channel encoding strategy.
Further, after determining whether the anchor level is greater than a preset level, the method further includes:
if the anchor level is smaller than the preset level, acquiring the current number of people watching; judging whether the current number of people is larger than a preset number of people or not; and if the current number of people watching the equipment is greater than the preset number of people, executing the step of judging whether the equipment performance exceeds the preset performance.
It should be noted that, if the anchor level is less than the preset level, that is, when the anchor level is an a-anchor, the current number of people watching is also required to be obtained, and when the current number of people watching is greater than the preset number of people, the step of judging whether the performance of the equipment exceeds the preset performance is executed, and whether a multi-path coding strategy is adopted is further judged, and when the current number of people watching is less than the preset number of people, a single-path coding strategy is adopted.
In a specific implementation, a live device is taken as an iPhone mobile phone for explanation, as shown in fig. 4, fig. 4 is a logic determination diagram of this embodiment, an iPhone x + mobile phone is a type of mobile phone whose device performance exceeds a preset performance, and an iPhone x-mobile phone is a type of mobile phone whose device performance does not exceed the preset performance, where the iPhone x + mobile phone is a device above the iPhone x.
It can be understood that whether the h.265 coding format is supported or not is judged, if the h.265 coding format is not supported, the h.264 coding format is adopted, if the h.265 coding format is supported, whether the anchor level is an a-anchor or an a + anchor is judged, if the anchor level is an a + anchor, whether the mobile phone is an iPhoneX + mobile phone or an iPhoneX-mobile phone is judged according to the mobile phone performance, if the mobile phone is an iPhoneX-mobile phone, the h.265 coding format is adopted, if the mobile phone is an iPhoneX + mobile phone, the current network state is 4G or Wifi is judged, if the current network state is 4G, the h.265 coding format is adopted, and if the current network state is Wifi, the h.265 coding format and the h.264 coding format are adopted.
And when the number of the audiences reaches the standard, the number of the current audiences is obtained, the number of the current audiences is compared with the preset number of the audiences to judge whether the number of the audiences reaches the standard, the step of judging whether the mobile phone is an iPhone X + mobile phone or an iPhone X-mobile phone according to the performance of the mobile phone is executed, and when the number of the audiences does not reach the standard, an H.264 coding format is adopted.
In the embodiment, whether a preset coding format is supported or not is judged according to the equipment performance; if the preset coding format is supported, acquiring anchor account information, and determining an anchor grade according to the anchor account information; and determining a corresponding target coding strategy according to the anchor level, the equipment performance and the current network state, thereby determining the corresponding target coding strategy through various information, and selecting the most appropriate target coding strategy on the premise of not wasting the equipment performance and not influencing the live broadcast effect.
In an embodiment, as shown in fig. 5, a third embodiment of the video data encoding method according to the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, the step S30 includes:
step S301, when the target coding strategy is a multi-path coding strategy, determining a target coding format corresponding to the multi-path coding strategy.
It should be noted that, when the target encoding policy is the multi-path encoding policy, the target encoding format corresponding to the multi-path encoding policy is determined, where the target encoding format includes a first encoding format and a second encoding format, where the first encoding format is an h.265 encoding format, and the second encoding format is an h.264 encoding format.

Further, the step S302 includes:
coding video data to be coded according to the first coding format to obtain a first coded video; coding the video data to be coded according to the second coding format to obtain a second coded video; the first encoded video and the second encoded video are treated as multiple encoded videos.
