Description

Technical Field

[0001] The present invention belongs to the technical field of VOLTE video calls, and in particular, relates to a method, storage medium, device and computer program product for recording and recording video based on VOLTE video calls. Background Art

[0002] VOLTE is based on the IP Multimedia Subsystem IMS network and uses specially designed profiles for the control layer and the media layer of voice services on LTE. This allows voice services to be transmitted as data streams in the LTE data bearer network, without the need to maintain and rely on traditional circuit-switched voice networks.

[0003] Currently, the recording and video recording services based on VOLTE video calls record the call at the same time. Both the call and the recording and video recording process require network bandwidth and memory space. When the network bandwidth or memory space is insufficient, the call quality will be reduced or interrupted, and the recording and video recording will be distorted or fail. At the same time, during the VOLTE video call, the audio call and video call can only be recorded separately. When either the caller or the called party switches the audio or video call, the entire call process cannot be fully recorded. Summary of the invention

[0004] In response to the problems existing in the prior art, the present invention provides a recording and videotaping method, storage medium, device and computer program product based on VOLTE video calls, which separate the call service from the recording and videotaping service to ensure that the recording and videotaping and the call do not affect each other, and can merge the recording and videotaping of switched audio and video calls to form a recording and videotaping file of a complete audio and video call.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a method for recording and videotaping a VOLTE video call, comprising the following steps:

[0006] Step S1: The caller and the called party establish a VOLTE video call, and the VOLTE call server initiates a SIP signaling recording request to the recording server;

[0007] Step S2, the recording and video recording server responds to the request of the VOLTE call server and performs recording and video recording, and records the calling party and the called party respectively to form a recording and video recording file;

[0008] Step S3: After the VOLTE video call ends, the audio and video files of each caller and callee in the call are extracted and merged into a file with audio and video;

[0009] Step S4: splice the audio and video files of the calling party and the called party respectively to form a complete call audio and video file of the calling party and a complete call audio and video file of the called party, and merge them into an audio and video file of the complete call between the calling party and the called party.

[0010] Furthermore, if either the caller or the called party switches the audio or video during the VOLTE video call, the current recording process is terminated, and a SIP signaling recording request is re-initiated to the recording server through the VOLTE call server.

[0011] Furthermore, in step S2, if the type of the VOLTE video call is an audio call, video image supplementation is required.

[0012] Furthermore, if multiple audio and video switching is performed during the VOLTE video call, multiple audio and video files are formed in chronological order, and each audio and video file is named: call unique identifier + calling number + called number + caller / called + file sequence number.

[0013] Furthermore, step S3 includes the following sub-steps:

[0014] Step S3.1: After the VOLTE video call ends, obtain the audio and video files of all the callers and callees;

[0015] Step S3.2: for each audio or video file, extract the .h264 raw code stream and .aac audio code stream of the audio or video file;

[0016] Step S3.3: repackage the extracted .h264 raw code stream into a file in mkv format, and then merge the .aac audio code stream and the file in mkv format into a file with audio and video.

[0017] Furthermore, step S4 includes the following sub-steps:

[0018] Step S4.1, splicing the audio and video files of the caller and the called party respectively to form a complete call audio and video file of the caller and the called party;

[0019] Step S4.2, extracting the caller's audio file from the caller's complete call recording and video file, extracting the called party's audio file from the called party's complete call recording and video file, and encapsulating the audio files into MP3 format;

[0020] Step S4.3: The complete audio and video file of the caller's call and the complete audio and video file of the called party's call are combined into a dual-channel video file to form an audio and video file of the complete call between the caller and the called party.

[0021] Furthermore, in step S4.3, the complete call recording and video file of the caller and the complete call recording and video file of the called party need to be uniformly scaled into 480×640 video files.

[0022] Furthermore, the present invention also provides a computer-readable storage medium storing a computer program, wherein the computer program enables a computer to execute the method for recording and videotaping based on VOLTE video calls.

[0023] Furthermore, the present invention also provides an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the method for recording and videotaping based on VOLTE video calls is implemented.

[0024] Furthermore, the present invention also provides a computer program product, including a computer program, which, when executed by a processor, implements the method for recording and videotaping based on VOLTE video calls.

[0025] Compared with the prior art, the present invention has the following beneficial effects: the recording and video recording method based on VOLTE video calls of the present invention separates the call service from the recording and video recording service, effectively ensures the normal progress of the call, and ensures the quality of the recording and video recording, and has high reliability and dynamic expansion capability; at the same time, the present invention can separately record and splice and merge multiple audio and video switches during a call, solves the problem of segmented recording and video recording caused by audio and video switching during VOLTE video calls, and provides a complete audio and video call recording and video recording file. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a flow chart of the recording and video recording method based on VOLTE video call of the present invention;

[0027] Figure 2 It is a flow chart of combining audio and video recording in the present invention. DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further explained below in conjunction with the accompanying drawings.

[0029] like Figure 1 The present invention is a flowchart of a recording and video recording method based on VOLTE video calls, and the recording and video recording method includes the following steps:

[0030] Step S1, the caller and the called party establish a VOLTE video call, and the VOLTE call server initiates a SIP signaling recording and recording request to the recording and recording server, separating the call service from the recording and recording service, effectively ensuring the normal progress of the call and the quality of the recording and recording, with high reliability and dynamic expansion capabilities.

[0031] If either the caller or the called party switches audio or video during a VOLTE video call, the current recording process ends, and the SIP signaling recording request is re-initiated to the recording server through the VOLTE call server, thus avoiding confusion or loss of recording content caused by mode switching and ensuring data integrity and consistency.

[0032] Step S2: After the recording and video recording server responds to the request of the VOLTE call server, it performs media negotiation and determines whether it is an audio call or a video call according to the media type in the recording and video recording request. If the type of the VOLTE video call is an audio call, it is necessary to supplement the video image so that the segment is displayed as an audio call during the recording and video recording process; and the calling party and the called party are recorded separately to form a recording and video recording file;

[0033] If multiple audio and video switches are performed during a VOLTE video call, multiple audio and video files are generated in chronological order, and each audio and video file is named: call unique identifier + calling number + called number + caller / called + file sequence number. When searching for specific call content later, users can quickly locate the corresponding audio and video files in chronological order. This efficient retrieval method helps improve work efficiency.

[0034] Step S3: After the VOLTE video call is ended, the audio and video files of each caller and callee in the call are extracted and merged into a file with audio and video; Figure 2 , specifically including the following sub-steps:

[0035] Step S3.1: After the VOLTE video call ends, obtain the audio and video files of all the callers and callees of the call. For each audio and video file, obtain the duration and number of frames of the video to calculate the bit rate.

[0036] Step S3.2: for each audio or video file, extract the .h264 raw code stream and .aac audio code stream of the audio or video file;

[0037] Step S3.3: repackage the extracted .h264 raw code stream into a file in mkv format, and then merge the .aac audio code stream and the file in mkv format into a file with audio and video.

[0038] Step S4, respectively splice the files with audio and video of the caller and the called party to form a complete call audio and video file of the caller and a complete call audio and video file of the called party, and merge them into an audio and video file of the complete call of the caller and the called party. The present invention can separately record and splice multiple audio and video switches during a call, solve the problem of audio and video switching causing audio and video segmentation during a VOLTE video call, and provide an audio and video file of a complete audio and video call, which specifically includes the following sub-steps:

[0039] Step S4.1, splicing the audio and video files of the caller and the called party respectively to form a complete call audio and video file of the caller and the called party;

[0040] Step S4.2, extracting the caller's audio file from the caller's complete call recording and video file, extracting the called party's audio file from the called party's complete call recording and video file, and encapsulating the audio files into MP3 format;

[0041] Step S4.3: Scale the caller's complete call recording and video file and the called party's complete call recording and video file into 480×640 video files according to the bit rate, and then synthesize the caller's complete call recording and video file and the called party's complete call recording and video file into a dual-channel video file to form a recording and video file of the complete call between the caller and the called party.

[0042] The recording and video recording method based on VOLTE video calls of the present invention can extract calling audio, called audio, calling video, called video, dual-track audio, and dual-track video according to the call records, so as to facilitate the retrieval of different call records as needed.
