现在我在这里提出与MPMoviePlayer
相关的新问题。我有一个表格视图,列出了ipad一面的视频,另一面 - 我播放列表中选择的视频。这些发生在同一视图中。现在切换到不同的视频工作正常。现在,当我使用UIVideoEditorController
编辑视频时,我正在替换文档文件夹中的当前视频文件,然后再次播放视频。但随后我的播放器停止工作......
我认为问题是UIVideoEditorController
内的玩家未正确发布。我发布了编辑器,但我仍然只在那里......再也没有工作:(
请尽快帮助我
-(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)

[[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:)

object:nil];
}
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self

object:nil];
}
从表格视图播放视频时调用此方法..
- (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];
}
编辑器成功返回时调用此方法。 之后我的视频无法播放
答案 0 :(得分:0)
最后,我通过在另一个视图控制器中使用UIVideoEditorController,然后延迟播放视频几秒钟来解决问题。可能发生这种情况是因为我试图播放正在被替换的视频。
