Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of a video file processing method according to an embodiment of the present application. The method and the device are suitable for the situation that the video file to be processed is processed to obtain the abnormal video file. The abnormal video file can be used for, but not limited to, processing and playing performance of the abnormal video file by the test playing end, and experience condition of a user after the abnormal video file is played by the test playing end. The embodiment may be performed by a video file processing apparatus, which may be implemented in software and/or hardware and may be integrated in an electronic device carrying video file processing functions. As shown in fig. 1, the method includes:
s101, selecting a video frame to be processed from video frames of a video file to be processed according to a user selection operation.
In this embodiment, the video file to be processed is composed of video frames, and the video frames of the video file to be processed can be obtained after decoding the video file to be processed in MP4, MKV, AVI and other formats, for example, the video frames can be in YUV format. The video file to be processed can be a network streaming media video file or a local video file. The video frame to be processed is an object to be processed selected from video frames of the video file to be processed, and optionally, the video frame to be processed may be at least one frame of the video frames of the video file to be processed.
When a player is tested, the scheme for simulating and reproducing the cartoon video generally transmits video streams and constructs frame loss video under the condition that a playing end uses a weak network environment. However, the time in the switching process of the scheme is uncontrollable, has randomness, and cannot adaptively and controllably construct the cartoon video under various conditions. In addition, the scheme of continuously starting and stopping a firewall or disabling a network card at a playing end by adopting a timing script can influence the transmission of the video stream, and the frame loss video can be constructed. However, the scheme also has randomness, can not effectively control frame loss, and can not construct the cartoon video under various conditions. In addition, neither of the above schemes can be configured to form repeated frames of a stuck video.
In this embodiment, when constructing an abnormal video file, first, according to a user selection operation, a to-be-processed video frame is selected from video frames of the to-be-processed video file, and parameters such as the number and types of the to-be-processed video frames may be selected according to actual situations, so that there are a plurality of abundant to-be-processed video frame selection situations.
Optionally, the user selection operation in the embodiment of the present application may be an operation specified by the user, for example, specifying a frame number by the user; a random framing operation selected by the user is also possible. Further, the frame number designated by the user may be used as the video frame to be processed, or the video frame to be processed may be randomly selected from among the video frames of the video file to be processed.
S102, mutation processing is carried out on the video frames to be processed in the video files to be processed, and abnormal video files are obtained.
In this embodiment, the mutation processing of the video frame to be processed includes, but is not limited to, frame loss processing and/or repeated frame processing. As shown in fig. 2. The frame loss processing may be performed by a frame loss processor and the repeated frame processing may be performed by a repeated frame processor. The frame loss processing may be deleting each frame of video in the video frames to be processed from the video file to be processed, so as to obtain an abnormal video file. The method may be to randomly discard a single frame, randomly discard a plurality of frames, discard a designated single frame (video frame number), discard a designated plurality of frames (video frame numbers), discard a designated section (start video frame number, end video frame number), or select a video frame discard from the designated sections. Optionally, the number of processed video files (i.e. abnormal video files) obtained after processing the video frames to be processed may be at least one, and may be consistent with the number of video frames to be processed or may not be consistent with the number of video frames to be processed.
For example, the abnormal video file obtained by the single frame loss processing may be at least one. Specifically, the to-be-processed video frames 1, 2 and 3 are deleted from the to-be-processed video file, and three files of the to-be-processed video frame 1, the to-be-processed video frame 2 and the to-be-processed video frame 3 are obtained.
The repeated frame processing is to add the video frame to be processed into the video file to be processed, so that the situation that the video frame to be processed is repeated is caused. Such as random single frame repetition, random multi-frame repetition, specified single frame (video frame number) repetition, specified multi-frame (multiple video frame numbers) repetition, specified interval (start video frame number, end video frame number) repetition, or selection of video frame repetition from specified intervals, etc. The repeated position, the repeated times and the like of the video frames to be processed in the video file to be processed can be set according to actual conditions. For example, the repeated processing of the video frames 1, 2 and 3 to be processed may be performed to obtain an abnormal video file including the repeated video frames to be processed arranged in 1, 2, 3, or an abnormal video file including the repeated video frames to be processed arranged in 1, 2, 3, an abnormal video file including the video frames to be processed arranged as 1, an abnormal video file of the video frames to be processed arranged as 2, an abnormal video file of the video frames to be processed arranged as 3, and the like can also be obtained. The above is merely an example of the number and form of the abnormal video files, and other abnormal video files may be generated, where the number and form of the generated abnormal video files may be determined according to the actual situation, and are not exhaustive herein. The cartoon video file in fig. 2 is the abnormal video file in the present embodiment.
According to the technical scheme, the video frames to be processed are flexibly selected from the video frames of the video files to be processed, so that the selected video frames to be processed are more comprehensive; and then, carrying out mutation processing on the video frames to be processed in the video files to be processed to obtain abnormal video files, solving the problems that the existing cartoon video reproduction construction has randomness and cannot comprise all the situations of actually generating the cartoon video, generating the abnormal video files under various conditions, being closer to the generation situation of the cartoon video in an actual scene, and providing a rich sample set for a playing end test.
As an alternative manner of this embodiment, after obtaining the abnormal video file, the method further includes: determining the number of video frames to be processed; the number is taken as the mutation degree of the abnormal video file.
In this embodiment, the mutation degree of the abnormal video file may be determined according to the number of the video frames to be processed, so as to quantitatively reflect the play clamping degree of the abnormal video file, so that in the subsequent test, the play end clamping degree which can be accepted by the user is clear. For example, the mutation degree of the abnormal video file may be proportional to the number of the video frames to be processed, that is, the greater the number of the video frames to be processed, the higher the mutation degree of the abnormal video file. For example, when the number of video frames to be processed is 10, the degree of variance of the abnormal video file is 1 level, when the number of video frames to be processed is 20, the degree of variance of the abnormal video file is 2 level, when the number of video frames to be processed is 30, the degree of variance of the abnormal video file is 3 level, and so on. And determining the linear relation between the mutation degree of the abnormal video file and the number of the video frames to be processed according to the data, thereby determining the mutation degree of the abnormal video file corresponding to the number of other video frames to be processed. In addition, the number of the video frames to be processed can be directly determined as the mutation degree of the abnormal video file. For example, when the number of video frames to be processed is 1, the degree of variance of the abnormal video file is 1 level, when the number of video frames to be processed is 2, the degree of variance of the abnormal video file is 2 level, when the number of video frames to be processed is 3, the degree of variance of the abnormal video file is 3 level, and so on.
The method has the beneficial effects that the variation degree of the abnormal video files can be quantitatively represented according to the number of the video frames to be processed, so that the variation degree of the abnormal video files obtained by different variation processes can be clearly determined, and the corresponding relation between the variation degree of each abnormal video file and the playing performance of the player and the degree of the click-on which can be accepted by a user can be clearly determined in the subsequent player test.
Fig. 3 is a flowchart of another video file processing method according to an embodiment of the present application. The present embodiment further explains selection of a video frame to be processed from among video frames of a video file to be processed on the basis of the above embodiment. As shown in fig. 3, the method includes:
s201, determining the frame type of the video frame in the video file to be processed.
The frame types may include key frames (I frames), difference frames (P frames), and bi-directional difference frames (B frames), among others. In video compression, each frame represents a still image. While in actual compression, various algorithms are adopted to reduce the data capacity, wherein the IPB is one algorithm for reducing the data capacity. The I frame represents a key frame, and the complete reservation of the key frame picture can be completed only by key frame data during decoding. The P-frame represents the difference between this frame and a previous key frame (or P-frame), and the difference defined by this frame needs to be overlapped with the previously buffered picture when decoding, so as to generate the final picture. The B frame is a bi-directional difference frame, that is, the B frame records the difference between the present frame and the previous and subsequent frames. To decode a B frame, not only a previous buffer picture but also a subsequent picture is obtained, and a final picture is obtained by superimposing the previous and subsequent pictures with the present frame data. In this embodiment, for the decoded video file to be processed, the frame type of the video frame may be determined, and it is clear which of the I frame, the P frame, or the B frame is the video frame.
S202, displaying the video frames and the frame types of the video frames to a user.
In order to enable the user to freely select the video frames to be processed so as to obtain various selection conditions of the video frames to be processed, in this embodiment, the video frames in the video file to be processed and the frame types of the video frames are displayed to the user, so that the user can select the video frames to be processed according to the actual conditions and requirements according to the displayed video frames and the frame type adaptability of the video frames. The video frames and frame types of the video frames may be presented to the user through a visual interface, and the specific presentation form may be in a graphic form or a list form, which is not limited herein.
S203, selecting the video frames to be processed from the video frames of the video files to be processed according to the user selection operation.
In this embodiment, the selection operation by the user may be an option selection operation or an input operation acting on the visual interface. The option selection operation or the input operation may be a manual operation or a voice operation. The user can be prompted to select the video frame to be processed on the visual interface, and the video frame selected by the user can be used as the video frame to be processed after the selection operation of the user is obtained. The user can be prompted on the visual interface to select the video frames which are not processed, and after the selection operation of the user is obtained, all video frames in the video file to be processed except the video frames selected by the user can be used as the video frames to be processed. Other setting forms can be set in the visual interface to determine the video frames to be processed according to the selection operation of the user.
S204, mutation processing is carried out on the video frames to be processed in the video files to be processed, and abnormal video files are obtained.
In this embodiment, after determining the video frame to be processed according to the selection operation of the user, the mutation operation may be performed on the video frame to be processed. Illustratively, depending on the user selection, the frame type of the resulting video frame to be processed may include one of a P frame, an I frame, a B frame, a P frame and an I frame, a P frame and a B frame, an I frame and a B frame, a P frame and an I frame, and a B frame. For the case that the video frame to be processed is a single frame, that is, the case that the video frame to be processed is one frame of a P frame, an I frame or a B frame, the mutation processing may include frame loss processing and/or repeated frame processing. Taking the frame type of the video frame to be processed as a P frame as an example, at least one frame with the frame type of the P frame can be discarded from the video frames of the file to be processed, so as to obtain the abnormal video file. And repeating at least one frame with the frame type of P frames in the video frames of the file to be processed to obtain the abnormal video file. And repeating the frame operation on at least one frame with the frame type of P frame, and discarding at least one frame with the frame type of P frame to obtain the abnormal video file. For the case that the video frame to be processed is two frames or more, the mutation processing can be performed including frame loss processing and/or repeated frame processing. Taking the case that the frame type of the video frame to be processed is a P frame and an I frame as an example, at least one frame of which the frame type is a P frame and at least one frame of which the repeating frame type is an I frame may be discarded from the video frames of the video file to be processed; or at least one frame with the frame type of I frame can be discarded from video frames of the video file to be processed, and at least one frame with the repeated frame type of P frame can be discarded; or at least one frame with the frame type of P frame and at least one frame with the frame type of I frame can be discarded from the video frames of the video file to be processed, or the at least one frame with the frame type of P frame and the at least one frame with the frame type of I frame can be repeated in the video frames of the video file to be processed. The mutation process may be performed in at least one item to obtain at least one abnormal video file. Specifically, the processing of the video frames to be processed can be set according to actual conditions so as to meet the requirements of player testing. In order to be able to test the performance of the player against a variety of situations, the type of mutation processing performed on the video frames to be processed may be made as many as possible to obtain a rich sample set.
It should be noted that the foregoing is merely an example of exception handling, and is not exhaustive, and any scheme that performs frame loss and/or repeated frame processing on a video frame to be processed is within the scope of protection of the present application.
According to the technical scheme, the frame type of the video frame in the video file to be processed is determined; displaying the video frames and the frame types of the video frames to a user; according to the selection operation of the user, the video frames to be processed are selected from the video frames of the video files to be processed, so that the video frames to be processed are adaptively determined according to the requirements of the user, the problem that the construction of the cartoon video reproduction has randomness and cannot include all the situations of actually generating the cartoon video is solved, the video frames to be processed in various situations are obtained according to the selection of the user to be processed, and the sample set tested by the player is enriched.
As an alternative manner of this embodiment, selecting a video frame to be processed from video frames of a video file to be processed according to a user selection operation may include: and selecting the video frames to be processed from the video frames of the video file to be processed according to the frame numbers specified by the user.
For example, the user may not select a video frame to be processed for the type of video frame, but rather refer to the type of video frame, designate the frame number of the video frame, and determine the video frame to be processed according to the frame number. The user can be prompted to select the frame number of the video frame to be processed, and the video frame corresponding to the frame number selected by the user is used as the video frame to be processed. The user can be prompted to select the frame number of the video frame which is not processed, and the frame number which is selected by the user is used as the frame to be processed except the frame number which corresponds to the frame number in all the video frames of the video file to be processed. The user may be prompted to select a start frame number and a stop frame number of the designated number interval, and the video frame to be processed is selected from the designated number interval determined by the start frame number and the stop frame number. The selection of the video frames to be processed from the designated number interval may be a random selection or a designated selection for the user. The scheme further enriches the forms and types of the video frames to be processed, so that the subsequent mutation processing is facilitated, and a rich player test sample set is obtained.
Fig. 4 is a flowchart of yet another video file processing method according to an embodiment of the present application. The present embodiment further explains selection of a video frame to be processed from among video frames of a video file to be processed on the basis of the above embodiment. As shown in fig. 4, the method includes:
s301, carrying out random full arrangement on the numbers of video frames of the video file to be processed.
Illustratively, the total number n of frames of the video frames in the video file to be processed is determined, including the number 0- (n-1). The numbers of n video frames are randomly and fully arranged to obtain a digital queue with the disordered numbers, for example, digital queues with the numbers of 4, 7, 0, 8, 3, 15 and … … can be obtained.
S302, selecting a video frame to be processed from video frames of the video file to be processed according to the arrangement result and the user selection operation.
In this embodiment, if the user selection operation is the user-specified operation, the arrangement result may be displayed to the user, and the user selects the video frame to be processed, for example, the user may select to determine the video frame to be processed from the video frames arranged in front, may select to determine the video frame to be processed from the video frames arranged in rear, and may select to determine the video frame to be processed from the video frames arranged in the middle. The number of selected video frames to be processed may also be determined based on a user selection operation.
If the user selection operation is the random frame selection operation, randomly selecting a preset number of video frames from the digital queue to serve as the video frames to be processed. For example, a preset number of video frames arranged in front of the digital queue may be randomly selected as the video frames to be processed, a preset number of video frames arranged at the end of the digital queue may be randomly selected as the video frames to be processed, and a preset number of video frames may be randomly selected from the middle position of the digital queue as the video frames to be processed. The preset number can be set according to actual conditions. For example, for the number queues of numbers 4, 7, 0, 8, 3, 15, … …, the video frames corresponding to the first 5 numbers arranged can be selected as the video frames to be processed, and the video frames of numbers 4, 7, 0, 8, 3 can be selected as the video frames to be processed.
S303, mutation processing is carried out on the video frames to be processed in the video files to be processed, and abnormal video files are obtained.
In this embodiment, the mutation processing of the video frames to be processed is the same as that of the above embodiment, that is, a single video frame to be processed may be selected to perform frame loss and/or frame repetition operations according to actual needs, or a plurality of video frames to be processed may be selected to perform frame loss and/or frame repetition operations, so long as a scheme of performing frame loss and/or frame repetition processing on the video frames to be processed is within the protection scope of the present application.
According to the technical scheme, the numbers of the video frames of the video file to be processed are randomly and fully arranged, and the video frames to be processed are selected from the video frames of the video file to be processed according to the arrangement result, so that various selectable combination forms of the video frames to be processed are provided, variation processing is carried out on the combination forms of the video frames to be processed to obtain abnormal video files under various conditions, and a sample set tested by a player is enriched.

In this embodiment, after determining the number of single mutation frames, a continuous video frame satisfying the number of single mutation frames is selected from the video frames of the video file to be processed as the video frame to be processed. For example, if the number of single mutation frames is 2, 2 consecutive frames are selected from the video file to be processed as the video frames to be processed. If the number of the single compiling frames is 10 frames, selecting continuous 10 frames from the video file to be processed as the video frames to be processed. The positions of the selected continuous video frames in the video file to be processed can be set according to actual conditions, and the positions can be designated by a user or randomly selected after a random operation mode is selected for the user.

In this embodiment, the abnormal video file obtained by performing mutation processing on the video frame to be processed in the file to be processed may be at least one. For example, if the number of single mutation frames is 3, 3 consecutive video frames are selected from the video file to be processed as video frames to be processed, which may be, for example, the 5 th frame, the 6 th frame, and the 7 th frame. The number of abnormal video files obtained after the mutation processing is not particularly limited as long as it is ensured that the mutation processing is performed once for each of the 5 th, 6 th and 7 th frames. The method includes the steps of copying video files to be processed to obtain 3 identical video files to be processed, performing frame loss processing on a 5 th frame in a 1 st video file to be processed to obtain a 1 st abnormal video file, performing frame loss processing on a 6 th frame in a 2 nd video file to be processed to obtain a 2 nd abnormal video file, and performing frame loss processing on a 7 th frame in a 3 rd video file to be processed to obtain a 3 rd abnormal video file. Or, copying the video files to be processed to obtain 2 identical video files to be processed, and performing frame loss processing on the 5 th frame and the 6 th frame in the 1 st video file to be processed to obtain the 1 st abnormal video file. And carrying out frame loss processing on the 7 th frame in the 2 nd video file to be processed to obtain the 2 nd abnormal video file. The foregoing is not exhaustive, and other abnormal video files may be obtained for other situations, where the frame loss process may also be a repeated frame process.
According to the technical scheme, the number of single variation frames is determined; according to the single mutation frame number, the video frames to be processed are selected from the video frames of the video files to be processed, so that selectable combination forms of various video frames to be processed and mutation processing conditions are provided, abnormal video files under various conditions are obtained, and a sample set tested by a player is enriched.
