I need to change video I'd, so the URL got changed. Is it possible? As far as I can see from docs - its not supported... So is there any other way to change video URL programmatically?
Example:
When I uploaded video i received URL: youtube.com/watch?v=EMSGJdnDN8U Now (next day) I want to keep uploaded video on server, but i don't want URL youtube.com/watch?v=EMSGJdnDN8U to be available anymore, but the original video should be available on youtube.com/watch?=nEwUrL100500 (new url) and so on...
Of course I know that i can reupload video and delete original one but i dont like that solution.
Sorry, I don’t think so. The video id is a very important identifier for YouTube and it’s very unlikely that they give you control over it.
I have the reference of a MPMediaItem when user selects an audio from the iPod library. I am getting the asset url of that item by using
let url = item.valueForProperty(MPMediaItemPropertyAssetURL)
But this is not giving me the exact physical location of the file, instead it is giving me an url w.r.t iPod library.
ipod-library://item/item.mp3?id=1840064795502796074
Is there a way to get the physical url of a song from iPod library?
EDIT - actually I want to extract NSData from the physical file and send it to my backend server, so i need the physical file URL and not the relative URL
Due to copyright protection you can only play songs from music library. You can't access row audio file! But there are some tricks that can help like you can export music because you can do mixing type of stuff and after creating your new edited file you have new copy of your music file and you can send it I thing, but can't send directly from library like you send photo and video! You have to export it with export session first!
Refer this so post for that!
You should refer Apple sample code for that
And this so post and this tutoria also may helpful to you!
How can I access the GameCenter player's photo URL? I know about loadPhotoForSize but it seems to return UIImage. I need the URL as I would like to send this URL to my backend and show this photo for users from non-iOS devices.
There is no available GameCenter player's photo URL. It may exist right now, but Apple can change it any moment. And it is not in open access.
Correct way to show player's photo on another non-iOS platforms is to upload this photo to your game servers. Use loadPhotoForSize to obtain UIImage and than upload it to your server. For example you can use answers from here: ios Upload Image and Text using HTTP POST
Apple will introduce Live Photo in iOS 9/iPhone 6s. Where is the file format documented?
A live photo has two resources. They are tied together with an asset identifier (a UUID as a string).
A JPEG; this must have a metadata entry for kCGImagePropertyMakerAppleDictionary with [17 : assetIdentifier] (17 is the Apple Maker Note Asset Identifier key).
A Quicktime MOV encoded with H.264 at the appropriate framerate (12-15fps) and size (1080p). This MOV must have:
Top-level Quicktime Metadata entry for ["com.apple.quicktime.content.identifier" : assetIdentifier]. If using AVAsset you can get this from asset.metadataForFormat(AVMetadataFormatQuickTimeMetadata)
Timed Metadata track with ["com.apple.quicktime.still-image-time" : 0xFF]; The actual still image time matches up to the presentation timestamp for this metadata item. The payload seems to just be a single 0xFF byte (aka -1) and can be ignored. If using an AVAssetReader you can use CMSampleBufferGetOutputPresentationTimeStamp to get this time.
The assetIdentifier is what ties the two items together and the timed metadata track is what tells the system where the still image sits in the movie timeline.
Here's the link. Otherwise, here's the text:
Live Photos
Live Photos is a new feature of iOS 9 that allows users to capture and
relive their favorite moments with richer context than traditional
photos. When the user presses the shutter button, the Camera app
captures much more content along with the regular photo, including
audio and additional frames before and after the photo. When browsing
through these photos, users can interact with them and play back all
the captured content, making the photos come to life.
iOS 9.1 introduces APIs that allow apps to incorporate playback of
Live Photos, as well as export the data for sharing. There is new
support in the Photos framework to fetch a PHLivePhoto object from the
PHImageManager object, which is used to represent all the data that
comprises a Live Photo. You can use a PHLivePhotoView object (defined
in the PhotosUI framework) to display the contents of a Live Photo.
The PHLivePhotoView view takes care of displaying the image, handling
all user interaction, and applying the visual treatments to play back
the content.
You can also use PHAssetResource to access the data of a PHLivePhoto
object for sharing purposes. You can request a PHLivePhoto object for
an asset in the user’s photo library by using PHImageManager or
UIImagePickerController. If you have a sharing extension, you can also
get PHLivePhoto objects by using NSItemProvider. On the receiving side
of a share, you can recreate a PHLivePhoto object from the set of
files originally exported by the sender.
Guidelines for Displaying Live Photos
It’s important to remember that a Live Photo is still a photo. If you have to display a Live Photo in
an environment that doesn’t support PHLivePhotoView, it’s recommended
that you present it as a regular photo.
Don’t display the extra frames and audio of a Live Photo separately.
It's important that the content of the Live Photo be presented in a
consistent way that uses the same visual treatment and interaction
model in all apps.
It’s recommended that you identify a photo as a Live Photo by placing
the badge provided by the PHLivePhotoView class method
livePhotoBadgeImageWithOptions:PHLivePhotoBadgeOptionsOverContent in
the top-left corner of the photo.
Note that there is no support for providing the visual effect that
users experience as they swipe through photos in the Photos app.
Guidelines for Sharing Live Photos
The data of a Live Photo is
exported as a set of files in a PHAssetResource object. The set of
files must be preserved as a unit when you upload them to a server.
When you rebuild a PHLivePhoto with these files on the receiver side,
the files are validated; loading fails if the files don’t come from
the same asset.
If your app lets users apply effects or adjustments to a photo before
sharing it, be sure to apply the same adjustments to all frames of the
Live Photo. Alternatively, if you don’t support adjusting the entire
contents of a Live Photo, share it as a regular photo and show an
appropriate indication to the user.
If your app has UI for picking photos to share, you should let users
play back the entire contents so they know exactly what they are
sharing.When selecting photos to share in your app, users should also
be able to turn a Live Photo off, so they can post it as a traditional
photo.
Outside of the documentation, Live Photos are made up of 2 resources, an image and an mov (quicktime movie file). So every Live Photo has 2 'actual' files connected by the wrapper of the Live Photo type.
Live Photos is actually two files. Original JPEG Image and Full HD Video.
Uniform Type Identifier (UTI) for the format is kUTTypeLivePhoto / com.apple.live-photo
#available(OSX 10.12, *)
public let kUTTypeLivePhoto: CFString
/*
*
* kUTTypeLivePhoto
*
* Live Photo
*
* UTI: com.apple.live-photo
*
*
*/
some additional info about live photos:
agree, it has .mov file extension
it saved in directory /var/mobile/media/DCIM/100apple/ alongside
with jpg version of photo
live photos can be played even on device without 3D touch (I can
play it on my ipad 2017 via long-pressing on the photo)
it can be played even on old phones (such as iphone 5) even on iOS8
if you install PhotosLive tweak
As i saw this in "Viber" application. There is media sharing button which opens all the albums as shown in photos native application. Can we do this ? I found UIImagePickerController cannot shows both simultaneously. How show both photo gallery and video gallery simultaneously ?
You're right about UIImagePickerController here great guide, and github project for picking media.
If you want to share your media here's some cool examples:
Check this tutorial on how to share pictures via email.
If you want to share via mail -
First of all you have to Create NSData object from your PNG/JPEG image data and then implement the method: Send addAttachmentData:mimeType:filename: to your MFMailComposeViewController instance.
Also i think the best thing to use in your case to share stuff like text, pictures etc is Sharekit.
