現在我在這裏提出與MPMoviePlayer
有關的新問題。我有一個桌面視圖,在ipad的一側列出視頻,在另一側 - 我播放列表中選擇的視頻。這些發生在同一視圖中。現在切換到不同的視頻效果很好。現在,當我使用UIVideoEditorController
編輯視頻時,我將替換文檔文件夾中的當前視頻文件,然後再次播放視頻。但後來我的球員停止工作...使用MPMoviePlayer播放視頻
我認爲問題是UIVideoEditorController
內的球員沒有正確發佈。我發佈了編輯器,但還是我只是有..沒有什麼作品AGAIN :(
請幫我儘快
-(void)playVideoWithIndex:(NSNumber *)index1
{
int index = [index1 intValue];
indexVideo = [index1 intValue];
if(index > [SourceArray count]){
NSLog(@"dg");
return;
}
if (mp) {
[mp stop];
[mp.view removeFromSuperview];
[mp release];
mp=nil;
}
// NSArray *sourcePaths=[[NSArray alloc] initWithArray:[[NSBundle mainBundle] pathsForResourcesOfType:@"mov" inDirectory:nil]];
videoDtls *v =[SourceArray objectAtIndex:index];
lbl_date.text=v.iVideoDate;
lbl_Title.text=v.iVideoTitle;
lbl_description.text=v.iVideoDesc;
lblDesc.text = @"Description";
lable_title.text = v.iVideoTitle;
NSString *documentFolderPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *mainImageFolderPath=[documentFolderPath stringByAppendingPathComponent:@"Videos"];
NSString *urlStr = [mainImageFolderPath stringByAppendingPathComponent:v.iVideoPath];
self.vpath = urlStr;
NSLog(@"asdsd %@",urlStr);
NSURL *url = [NSURL fileURLWithPath:urlStr];
mp = [[MPMoviePlayerController alloc] initWithContentURL:url];
if ([mp respondsToSelector:@selector(loadState)])
{
// Set movie player layout
//[mp setControlStyle:MPMovieControlStyleFullscreen];
//[mp setFullscreen:YES];
// May help to reduce latency
[mp prepareToPlay];
mp.useApplicationAudioSession = NO;
// mp.controlStyle = MPMovieControlStyleDefault;
// mp.useApplicationAudioSession = YES;
// Register that the load state changed (movie is ready)
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayerLoadStateChanged:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayerEnterFullScreen:)
name:MPMoviePlayerDidEnterFullscreenNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self

object:nil];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(moviePlayerDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[[mp view] setFrame:CGRectMake(0, 0, 480, 320)];
// Add movie player as subview
[playerView addSubview:[mp view]];
mp.initialPlaybackTime = -1.0;
}
else
{
// Register to receive a notification when the movie is in memory and ready to play.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePreloadDidFinish:)
name:MPMoviePlayerContentPreloadDidFinishNotification
object:nil];
}
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
}
當一個視頻從表視圖進行播放時調用此方法。 。
- (void)videoEditorController:(UIVideoEditorController *)editor didSaveEditedVideoToPath:(NSString *)editedVideoPath
{
CFShow(editedVideoPath);
NSFileManager *fileManager = [[NSFileManager alloc] init];
NSError *error = nil;
NSString *path = self.vpath;
NSLog(@"PATH %@", self.vpath);
if([fileManager removeItemAtPath:path error:&error] != YES){
NSLog(@"ERROR 1 : %@",[error localizedDescription]);
}
else{
// can do save here. the data has *not* yet been saved to the photo album
if ([fileManager copyItemAtPath:editedVideoPath toPath:path error:&error] != YES)
NSLog(@"Can't move file with error: %@", [error localizedDescription]);
}
[popOver dismissPopoverAnimated:YES];
[self dismissMoviePlayerViewControllerAnimated];
[editor release];
[self performSelector:@selector(playVideoWithIndex:) withObject:[NSNumber numberWithInt:indexVideo] afterDelay:0.2];
}
當編輯器返回SUC這種方法被稱爲cessfully。 此後我的視頻不播放
