Android online video playback

Source: Internet
Author: User

During this time, I always saw online video playback materials and summarized them as follows:

1. You don't have to say anything about playing a local video, whether it's videoview, surfaceview, or mediaplayer.

2. Online playback server video:

A. You can use videoview or surfaceview to play a video in progressive download format.

B. Streaming Media videos can also be used (this is the best and most popular. It's a pity that I have read some materials and I haven't done it yet ...)

The code for implementing progressive download video playback is attached below:

Package CN. itcast. videoplayer;

Import java. Io. file;

Import Android. App. activity;
Import Android. Media. mediaplayer;
Import Android. Media. mediaplayer. onpreparedlistener;

Import Android. OS. environment;
Import Android. View. surfaceholder;
Import Android. View. surfaceholder. Callback;
Import Android. View. surfaceview;
Import Android. View. view;
Import Android. widget. edittext;
Import Android. widget. Toast;

Public class mainactivity extends activity {
Private edittext nametext;
Private string path;
Private mediaplayer;
Private surfaceview;
Private Boolean pause;
Private int position;

@ Override
Public void oncreate (bundle savedinstancestate ){
Super. oncreate (savedinstancestate );
Setcontentview (R. layout. Main );

Mediaplayer = new mediaplayer ();
Nametext = (edittext) This. findviewbyid (R. Id. filename );
Surfaceview = (surfaceview) This. findviewbyid (R. Id. surfaceview );

Surfaceview. getholder (). settype (surfaceholder. surface_type_push_buffers );
Surfaceview. getholder (). setfixedsize (176,144 );
Surfaceview. getholder (). setkeepscreenon (true );
Surfaceview. getholder (). addcallback (New surfacecallback ());
}

Private final class surfacecallback implements callback {
Public void surfacechanged (surfaceholder holder, int format, int width, int height ){
}
Public void surfacecreated (surfaceholder holder ){
If (position> 0 & path! = NULL ){
Play (position );
Position = 0;
}
}
Public void surfacedestroyed (surfaceholder holder ){
If (mediaplayer. isplaying ()){
Position = mediaplayer. getcurrentposition ();
Mediaplayer. Stop ();
}
}
}

@ Override
Protected void ondestroy (){
Mediaplayer. Release ();
Mediaplayer = NULL;
Super. ondestroy ();
}

Public void mediaplay (view v ){
Switch (V. GETID ()){
Case R. Id. playbutton:
String filename = "http://daily3gp.com/vids/family_guy_penis_car.3gp ";
If (filename. startswith ("HTTP ")){
Path = filename;
Play (0 );
} Else {
File file = new file (environment. getexternalstoragedirectory (), filename );
If (file. exists ()){
Path = file. getabsolutepath ();
Play (0 );
} Else {
Path = NULL;
Toast. maketext (this, R. String. filenoexsit, 1). Show ();
}
}

Break;

Case R. Id. pausebutton:
If (mediaplayer. isplaying ()){
Mediaplayer. Pause ();
Pause = true;
} Else {
If (pause ){
Mediaplayer. Start ();
Pause = false;
}
}
Break;

Case R. Id. resetbutton:
If (mediaplayer. isplaying ()){
Mediaplayer. seekto (0 );
} Else {
If (path! = NULL ){
Play (0 );
}
}
Break;
Case R. Id. stopbutton:
If (mediaplayer. isplaying ()){
Mediaplayer. Stop ();
}
Break;
}
}

Private void play (INT position ){
Try {
Mediaplayer. Reset ();
Mediaplayer. setdatasource (PATH );
Mediaplayer. setdisplay (surfaceview. getholder ());
Mediaplayer. Prepare (); // Buffer
Mediaplayer. setonpreparedlistener (New preparelistener (position ));
} Catch (exception e ){
E. printstacktrace ();
}
}

Private final class preparelistener implements onpreparedlistener {
Private int position;

Public preparelistener (INT position ){
This. Position = position;
}

Public void onprepared (mediaplayer MP ){
Mediaplayer. Start (); // play the video
If (position> 0) mediaplayer. seekto (position );
}
}
}

I am writing the URL to death. Otherwise, you can enter the URL through edittext. The video in the URL must be in progressive download format. (You can use code to convert a video to a progressive download format. You can also use quicktime to export the video to a progressive download format)
