I want to upload a video to webserver. I can upload the video but the problem is how should i pick a video. Means I know there is a default UIImagePickerController that i can use to pick image, is there any thing similar to pick movies in iPhone?
Hope you are getting my problem.
Thanks
Check out this SO entry. It has a similar discussion.
NSString *path = [[NSBundle mainBundle] pathForResource:#"ddd" ofType:#"avi"];
NSData *data = [NSData dataWithContentsOfFile:path];
Assets library is another option that you can fetch all photos and videos programaticaly but in that you case you have to make your own pickerviewcontroller .
Use AVFoundation to capture video and upload it using MKNetworkKit.

I am writing a small POC to play the video in iPhone app. I would like to do so in UIWebView with the help of HTML5. I dont want to use standard players like AVPlayer or MPMoviePlayerController.
Can someone throw some light on it?..
I am new to this HTML5 environment on iPhone. So, any help to start this POC would be appriciated.
I forget to add that i would like to play h264 live stream on server.
Thanks in advance.
Yes, you can do that:
NSString *bundleDirectory = [[NSBundle mainBundle] pathForResource:#"mov" ofType:nil];
NSString *filePath = [bundleDirectory stringByAppendingPathComponent:#"loopvideo.html"];
NSString *HTMLData = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
[self.web loadHTMLString:HTMLData baseURL:[NSURL fileURLWithPath:bundleDirectory]];
In your HTML, you can embed the <video> tag and it should play.
I want to play a movie in my app and the video is stored in my ipad library.
Can anyone provide me the necessary guidance for it?
Get the MPMediaItem of the video you want using MPMediaQuery
Get the Asset URL like this:
NSURL *videoURL = [mediaItem valueForProperty:MPMediaItemPropertyAssetURL];
Instantiate an MPMoviePlayerViewController using videoURL as the content URL.
If the video is stored in your App's bundle then do this to get the URL:
NSURL *videoURL = [[NSBundle mainBundle] URLForResource:#"nameoffile" withExtension:#"mp4"];
See a sample of a custom view/viewController combo in Pragmatic iPad Programming. Check the source code for chapter 8 (free download from that page). They use a video provided as a file inside the project. Btw, if the file in the video appears red in XCode, you'll have to remove it and re add it, I think the project definition is a bit screwed.
I have an app that plays video clips through the MPMovieplayer. These clips are in mp4 format and everything works dandy. I want to take that same clip and save it into the photo album. This works if I manually sync the video from a computer through iTunes to the phone. It appears to transcode the video file and store it as a .MOV format.
However, when I try and save the video while in the app via code, I get a video format error. So my question is how do I get my video to save in the photo album? If this is not possible with mp4 how do I transcode (in app) to .MOV?
Here is the code:
ALAssetsLibrary* library = [[ALAssetsLibrary alloc]init];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:moviePlayerController.contentURL])
{
NSURL *clipURl = moviePlayerController.contentURL;
[library writeVideoAtPathToSavedPhotosAlbum:clipURl completionBlock:^(NSURL *assetURL, NSError *error)
{
if (error)
[ErrorAlertView showError:error];
else [ErrorAlertView showErrorTitle:#"Success" message:#"Your video clip is saved"];
}];
}
[library release];
Is your contentURL a file path URL or a web URL? For the writeVideoAtPathToSavedPhotosAlbum method, in my testing you actually need a file path URL created (for example) in this way:
NSString *pathString = [[NSBundle mainBundle] pathForResource:#"filename" ofType:#"mp4"];
NSString *pathURL = [NSURL fileURLWithPath:pathString isDirectory:NO];
This means you need to first download the movie from the web, if you're using a web URL. I recommend ASIHTTPRequest, using the setDownloadDestinationPath: method to set the download directory.
In general, mp4 files should work if they're the right resolution for the right (retina, non-retina, iPad) device (see my tests of supported video files here).
If the video still gives a NO response on videoAtPathIsCompatibleWithSavedPhotosAlbum: after making absolutely sure the file path URL is correct, then you'll need to use AVAssetExportSession (with AVAssetExportPresetLowQuality, AVAssetExportPresetMediumQuality, or AVAssetExportPresetHighestQuality) to get a device-appropriate file that you can then save to the Photo Album.
I am currently recording video using AVFoundation api and have specified a fileUrl to write to:
NSURL *fileUrl = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#%#", NSTemporaryDirectory(), #"output.mov"]];
However, right now its recording to a temp directory. How do i write this file to the camera roll? Whats the camera roll directory?
Thanks!
After recording to the disk do the following to copy the video to Camera Roll
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(outFileName)) {
UISaveVideoAtPathToSavedPhotosAlbum(outFileName, self, #selector(video:didFinishSavingWithError: contextInfo:), nil);
}
Note that UIVideoAtPathIsCompatibleWithSavedPhotosAlbum() will be successful only of the recorded video is proper QuickTIme format.
I found some documentation on Apples site from the AVCamDemo code.
Playing Youtube video in the app is easy and well documented around.
There are two problems with that:
after closing Youtube player, if user wants to play it again it has to wait for online streaming again
can't play offline (load video at home to watch on the road)
Does anyone have code to:
download Youtube video to documents folder and show progress of download
play downloaded video by loading file from documents folder (meaning even when not connected to the internet)
To download the video from YouTube:
Get the URL to download from, via the YouTube API or whatever other method.
Create an NSOutputStream or NSFileHandle opened on a temporary file (in NSTemporaryDirectory() or a temp-named file in your Documents directory).
Set up your progress bar and whatever else you need to do.
Allocate and start an NSURLConnection to fetch the file from the URL. Do not use sendSynchronousRequest:returningResponse:error:, of course.
In the connection:didReceiveResponse: delegate method, read out the length of data to be downloaded for proper updating of the progress bar.
In the connection:didReceiveData: delegate method, write the data to the output stream/file handle and update the progress bar as necessary.
In connectionDidFinishLoading: or connection:didFailWithError:, close the output stream/file handle and rename or delete the temporary file as appropriate.
To play it back, just use NSURL's fileURLWithPath: to create a URL pointing to the local file in the Documents directory and play it as you would any remote video.
Ive used classes from this project: https://github.com/larcus94/LBYouTubeView
It works fine for me.
I can download youtube videos.
I used this code:
LBYouTubeExtractor *extractor = [[[LBYouTubeExtractor alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat:(#"http://www.youtube.com/watch?v=%#"), self.videoID ]] quality:LBYouTubeVideoQualityLarge] autorelease];
[extractor extractVideoURLWithCompletionBlock:^(NSURL *videoURL, NSError *error) {
if(!error) {
NSLog(#"Did extract video URL using completion block: %#", videoURL);
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSData *data = [NSData dataWithContentsOfURL: videoURL];
NSString *pathToDocs = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filename = [NSString stringWithFormat:(#"video_%#.mp4"), self.videoID ];
[data writeToFile:[pathTODocs stringByAppendingPathComponent:filename] atomically:YES];
NSLog(#"File %# successfully saved", filename);
});
} else {
NSLog(#"Failed extracting video URL using block due to error:%#", error);
}
}];
You can show progress of downloading using technique described in the posts above.
Here is my example: https://github.com/comonitos/youtube_video
I used PSYouTubeExtractor.h class by Peter Steinberger It can get youtube mp4 video url and than downloading and viewing is not a problem
NSURLConnection
+
NSNotificationCenter
+
PSYouTubeExtractor
+
NSMutableData

I don't personally know how to download youtube videos (and the code is too big to put in an answer here).
However, here's a complete youtube downloading example here.
It's an open source youtube downloader called LoadTube: here's the a link to the source code.
I would play the video and figure out where the temp file is being stored. If you can get access to it, copy it into some document folder for offline viewing.
