Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The specific embodiments described herein are merely illustrative of the invention and do not delimit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method for playing multi-machine-position live programs, which is shown in figure 1 and comprises the following steps:
s1, full-screen playing is carried out during video playing, and the whole picture is divided into an area A, an area B and an area C, wherein the area A is a multi-camera picture, the middle area B is a playing main picture, and the area C on the right side is a TA (just in time) picture;
the application scene of the video playing is mainly that video pictures are switched through a small left video and a close-up video of a fixed actor is selected to watch the video when a concert is live.
S2, confirming the occupied width of the area A as mLW, and calculating the actual height mLH of each video according to the video bandwidth height and the ratio of mLW;
the area A is hidden outside the left side of a screen, the area A needs to be hidden by moving left mLW by a setTranslationX method for hiding the area A, the area A is a video list, the video list is divided into a plurality of views of 4K ultra high definition, top shot pictures, dynamic pictures and stage close-up scenes, and the views of other scenes can be added into the video list according to actual use requirements.
When the area A is used for displaying the video list, the data list is displayed by using a RecycleView control, and then the content stream is directly projected into the View by using the TextureView, so that the video viewing experience of a user is greatly improved, and panoramic, overlooking and stage View video can be viewed in the live program of the Android client.
S3, confirming the width occupied by the area C as mRW, and calculating the height mRH of each actor picture according to the width and the height of the right actor picture and the ratio of mRW;
the C area is hidden outside the right side of the screen, the C area needs to be hidden by moving the C area right mRW in a setTranslationX method, the C area is an actor picture list, when a user clicks a certain actor picture, the B area can be inserted into the angle video of the close-up of the actor, the video watching experience of the user is greatly improved through the method, and the video watching of the single actor view angle can be switched in the live program of the Android client.
When the area C displays the actor close-up angle video, the area width of a main view B is set as W, then aW =1/3*W is the width of an inserted video, the height of the video is calculated according to the size of the original video and the proportion of aW to obtain aH, the area C is placed at the position of top-aH, and when a user clicks an actor picture, the corresponding video is drawn from the top through a Translateanimation animation method;
translateanimation is the animation effect of movement. It has three constructors, which are:
public TranslateAnimation was skipped.
Public TranslateAnimation (float from XDelta, float to XDelta, float from YDelta, float to YDelta) this is one of the most commonly used construction methods we use,
the parameter represents the difference value of the starting point of the animation from the current View X coordinate;
the parameter represents the difference value of the animation end point from the current View X coordinate;
float fromYDelta, which represents the difference of the point where the animation starts from the current View Y coordinate;
float toYDelta) this parameter represents the difference of the point where the animation starts from the current View Y coordinate;
if view is at point A (x, y) then the animation is moved from point B (x + fromXDelta, y + fromYDelta) to point C (x + toXDelta, y + toYDelta).
Public TranslateAnimation (int fromxype, float from xvvalue, int toXType, float to xvvalue, int fromvtypee, float from yvalue, int topYType, float to yvalue) from xvType. Reference fromXValue where the first parameter is a value in the x-axis direction: the second parameter is a starting value of the first parameter type; the third parameter and the fourth parameter are end point reference and corresponding values in the x-axis direction; the relationship between the reference and the corresponding value is described by taking the x-axis as an example: the corresponding value should be a specific coordinate value, such as 100 TO 300, if the reference is selected as animation, indicating absolute screen pixel units, and should be understood as several times or percent with respect TO the control itself or the PARENT control if the reference is selected as animation, relative _ TO _ SELF or animation, relative _ TO _ part.
And S4, the B area plays the multi-machine video through the TextureView control according to the selection of the user.
The TextureView control directly projects content streams into the View and is used for realizing the function of Live preview, and the TextureView control comprises a multi-View button and a TA-only-View button.
When playing multi-machine video, the following two situations occur:
a1, when a user clicks a multi-view button, calling a setTranslationX method for showing an A area view, namely moving the A area to the right mLW, and moving a B area view to the right mLW in a linkage manner, and at the moment, showing a multi-view video and displaying a selected video to realize multi-frequency simultaneous watching;
and A2, when the user clicks the TA-only button, the view in the area C calls a setTranslationX method to move left mRW for displaying the content of the area C, the area B moves left, and the area B displays a plurality of actor close-up videos.
Wherein, the setTranslationX method in steps A1 and A2 is a program for changing the position of the view, but not changing the margin attribute in the LayoutParams of the view, and the area B in step A2 shows the close-up video of the actor at most three.
By integrating the above, the left, middle and right areas of the video area A, the area B and the area C are calculated systematically according to the algorithm, and then the playing of the multi-station video is realized according to the view selected by the user, so that the better watching experience of the user is improved, and particularly, the method has better effect when the actor is watching the concert.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
