I am creating an original video player in swift.The following are used PHPickerviewcontroller,AVPlayer
I was able to select a video from my camera roll and draw the video in the view I specified, but I am unable to control it.Control methods are assumed to be playback and stop by buttons and seek bar.
I am having trouble getting the seek bar and the video I called to work together. Can you please tell me what is the best way to do this? Thank you in advance.
I recording video using MediaRecorder.When using back-camera,it working fine,but when using front camera,the video captured is being flipped/inverse.Means that the item in right,will appear on the left.The camera preview is working fine,just final captured video flipped.
Here is the camera preview looks like
But the final video appear like this(all the item in left hand side,appear on right hand side)
What I tried so far:
I tried to apply the matrix when prepare recorder,but it seems does change anything.
private boolean prepareRecorder(int cameraId){
//# Create a new instance of MediaRecorder
mRecorder = new MediaRecorder();
setCameraDisplayOrientation(this,cameraId,mCamera);
int angle = getVideoOrientationAngle(this,cameraId);
mRecorder.setOrientationHint(angle);
if(cameraId == Camera.CameraInfo.CAMERA_FACING_FRONT){
Matrix matrix = new Matrix();
matrix.preScale(1.0f,-1.0f);
}
//all other code to prepare recorder here
}
I already read for all this question below,but all this seems didnt solve my problem.For information,I using SurfaceView for the camera preview,so this question here doesn't help.
1) Android flip front camera mirror flipped video
2) How to keep android from inverting the image from the front facing camera?
3) Prevent flipping of the front facing camera
So my question is :
1) How to capture a video by front camera which the video not being inverse(exactly the same with camera preview)?
2) How to achieve this when the Camera preview is using SurfaceView but not TextureView ? (cause all the question I mention above,tell about using TextureView)
All possible solution is mostly welcome..Tq
EDIT
I made 2 short video clip to clarify the problem,please download and take a look
1) The video during camera preview of recording
2) The video of the final product of recording
So, if the system camera app produces video similar to your app, you didn't do something wrong. Now it's time to understand what happens to front-facing camera video recording.
The front facing camera is not different from the rear facing camera in the way it captures still pictures or video. There is a difference how the phone displays camera preview on the screen. To make it look more natural to the user, Android (and all other systems) mirrors the preview, so that you can see yourself as if in a mirror.
It is important to understand that this only applies to the way the preview is presented to you. If you pick up any video conferencing app, connect two devices that you hold in two hands, and look at yourself, you will see to your surprise that the two instances of yourself are flipped.
This is not a bug, this is the natural way to present the video to the other party.
See the sketch:
This is how you see the scene:
This is how your peer sees the same scene
Normally, recording of a video is done from the point if view of your peer, as in the second picture. This is the natural setup for, e.g., video conferencing.
But Snapchat and some other social apps choose to store the front-facing video clip as if you record it from the mirror (as if the recorder is in your hand on the first picture). Some people like this feature, others hate it (see https://forums.androidcentral.com/general-help-how/664539-front-camera-pics-mirrored-reversed-only-snapchat.html and https://www.reddit.com/r/nexus6/comments/3846ay/has_anyone_found_a_fix_for_snapchat_flipping)
You cannot use MediaRecorder for that. You can use the lower-level API of MediaCodec to record processed frames. You need to flip each frame 'manually', and this may be a significant performance hit, because normally the MediaRecorder 'connects' the camera to hardware encoder in a very efficient way, without need even to copy the pixels to user memory. This answer shows how you can manipulate the way camera is rendered to texture.
You can achieve this by recording video manually from surface view.
In such case preview and recording will match exactly.
I've been using this library for this purpose:
https://github.com/spaceLenny/recordablesurfaceview
Here is the guide how to use it (not with camera but with OpenGL drawing): https://withintent.uncorkedstudios.com/recording-screen-video-on-android-with-recordablesurfaceview-451c9daa213e
I'm working on the simple iPhone application to record the video and then choose the start and end frames of the videos to trim the selected duration of it.
I'm using UIImagepickercontroller to record the video and use it for choose the start and end frames to achieve this.
But i couldn't control the UI like changing the play/rewind icon position , adding the custom icons and choosing the frame selection.
Choosing the start and end frames is difficult to choose the frames.
Is it possible to achieve this by AVPlayer or any other framework ?
Is any other third party library to achieve to this ?
I would like to achieve the ui as below image :
I have been facing this since so many days but I have not reach to any conclusion.
My problem is : I want to play an mp3 file but not simply by clicking on a play button.
It is this way I want to play it.
*There is a slider that I can drag using finger, I want that the mp3 should play with the frequency with which I am dragging the finger (or speed with which I am dragging my finger, so that it will give an effect of fast forwarding (funny type of voice)) or if I drag slider slowyly the output will be slow *
The problem is the output of the sound is not coming out smooth. its very distorted and disturbed voice.
I want the outuput to be smoother.
Please help. Any suggestions please. Presently I am using AVAudioPlayer and passing the time value based upon slider input to play the file. (It does not seems to be feasible though).
I feel that it is possible using openAL only and no other way. Because using openAL we can modify the frequency of the sound file (pitch)
CAN SOME ONE PLEASE REFER ME A LINK TO openAL implementation for iPhone . I have never played a sound file using openAL
Help!!
You won't be able to do it with AVAudioPlayer, as it does not support pitch operations.
You can load and decode the entire track into memory for playback with OpenAL (which supports pitch), or you can do realtime loading/decoding and pitch changing using Audio Units (MUCH lower level, and more complicated, though).
I have requirement to record video from the visible view.i,e not form camera. like in TalkingTom application. Can any suggest the solution.
You can take screenshot (using UIGetScreenImage) and store the images into an array.
Then convert it into video using mpeg coder.
