Android development calls the phone's camera to use Mediarecorder video and play _android

Let's play the video function of the mobile phone. Do a demo.
look at the recording process：

Copy Code code as follows:

Mediarecorder = new Mediarecorder ();//Create Mediarecorder Object
Set the recording video source to camera (camera)
Mediarecorder.setvideosource (MediaRecorder.VideoSource.CAMERA);
Set the package format for the video after the recording is complete THREE_GPP to 3gp.mpeg_4 as MP4
Mediarecorder.setoutputformat (MediaRecorder.OutputFormat.THREE_GPP);
Sets the video encoding for the recording h263 H264
Mediarecorder.setvideoencoder (MediaRecorder.VideoEncoder.H264);
Sets the resolution of the video recording. Must be placed behind the set encoding and formatting, otherwise the error
Mediarecorder.setvideosize (176, 144);
Sets the video frame rate for the recording. Must be placed behind the set encoding and formatting, otherwise the error
Mediarecorder.setvideoframerate (20);
Mediarecorder.setpreviewdisplay (Surfaceview.getholder (). Getsurface ());
Set the path for video file output
Lastfilename = NewFileName ();
Mediarecorder.setoutputfile (Lastfilename);
try {
Preparing to record
Mediarecorder.prepare ();
Start recording
Mediarecorder.start ();
catch (IllegalStateException e) {
TODO auto-generated Catch block
E.printstacktrace ();
catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
End shooting:
if (Mediarecorder!= null) {
Stop it
Mediarecorder.stop ();
Mediarecorder.release ();
Mediarecorder = null;
}

sticking out my own package class：

Copy Code code as follows:

Package Zyf.demo.moviedemo;
Import Java.io.File;
Import java.io.IOException;
Import Java.util.Timer;
Import Java.util.TimerTask;
Import Android.media.MediaRecorder;
Import Android.view.SurfaceView;
public class Movierecorder {
Private Mediarecorder Mediarecorder;
Boolean isrecording;
public void startrecording (Surfaceview surfaceview) {
Mediarecorder = new Mediarecorder ();//Create Mediarecorder Object
Set the recording video source to camera (camera)
Mediarecorder.setvideosource (MediaRecorder.VideoSource.CAMERA);
Set the package format for the video after the recording is complete THREE_GPP to 3gp.mpeg_4 as MP4
Mediarecorder.setoutputformat (MediaRecorder.OutputFormat.THREE_GPP);
Sets the video encoding for the recording h263 H264
Mediarecorder.setvideoencoder (MediaRecorder.VideoEncoder.H264);
Sets the resolution of the video recording. Must be placed behind the set encoding and formatting, otherwise the error
Mediarecorder.setvideosize (176, 144);
Sets the video frame rate for the recording. Must be placed behind the set encoding and formatting, otherwise the error
Mediarecorder.setvideoframerate (20);
Mediarecorder.setpreviewdisplay (Surfaceview.getholder (). Getsurface ());
Set the path for video file output
Lastfilename = NewFileName ();
Mediarecorder.setoutputfile (Lastfilename);
try {
Preparing to record
Mediarecorder.prepare ();
Start recording
Mediarecorder.start ();
catch (IllegalStateException e) {
TODO auto-generated Catch block
E.printstacktrace ();
catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
IsRecording = true;
timesize = 0;
Timer = new timer ();
Timer.schedule (New TimerTask () {
@Override
public void Run () {
TODO auto-generated Method Stub
timesize++;
}
}, 0,1000);
}
Timer timer;
int timesize = 0;
Private String Lastfilename;
public void stoprecording () {
if (Mediarecorder!= null) {
Stop it
Mediarecorder.stop ();
Mediarecorder.release ();
Mediarecorder = null;
Timer.cancel ();
if (null!= lastfilename &&! "". Equals (Lastfilename)) {
File F = new file (lastfilename);
String name = F.getname (). substring (0,
F.getname (). LastIndexOf (". 3gp"));
Name + + "_" + timesize + "s.3gp";
String NewPath = F.getparentfile (). GetAbsolutePath () + "/"
+ Name;
if (F.renameto new File (NewPath)) {
int i = 0;
i++;
}
}
}
}
Public String NewFileName () {
try {
Return File.createtempfile ("/mov_", ". 3gp"). GetAbsolutePath ();
catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
return null;
}
}
public void release () {
if (Mediarecorder!= null) {
Stop it
Mediarecorder.stop ();
Mediarecorder.release ();
Mediarecorder = null;
}
} }

And then we'll play it as well:

Copy Code code as follows:

public void Play (String fileName, Surfaceview view) {
MPlayer = new MediaPlayer ();
Mplayer.setaudiostreamtype (Audiomanager.stream_music);
Mplayer.setdisplay (View.getholder ()); Define a Surfaceview Play it
Mplayer.setoncompletionlistener (New Oncompletionlistener () {
@Override
public void Oncompletion (MediaPlayer arg0) {
Stop ();
Canvas.drawcolor (Color.transparent,
PorterDuff.Mode.CLEAR);
}
});
try {
Mplayer.setdatasource (FileName);
Mplayer.prepare ();
catch (IllegalStateException e) {
TODO auto-generated Catch block
E.printstacktrace ();
catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
Mplayer.start ();
}
At the end of playback:
public void Stop () {
if (MPlayer!= null) {
Mplayer.release ();
MPlayer = null;
}
}
