I am in need for some help as I am stuck with a problem with my current IPhone application. I won't go into every details but the mainline is as follow:
I am currently playing videos from a remote URL. Everthing up to this point is working. But we need to add a certain validation as if the video exists on the local IPhone, play this version and otherwise, get the remote version. I get these informations from an XML feed and have the name of the video and it's remote URL.
I've implemented the ALAssetLibrary as a way to retrieve the locals video and transfered 3-4 videos with custom names. After some struggling, I could play these local video. But while I loop through them, all I get is names like 00001.jpg, etc.
Is there any way to get a local video name ? I don't mind if this needs another library but I would appreciate if someone could point me a way of doing it.
Thanks for your time,
AP
You don't have access to the local filenames, and even if you did those filenames would probably not be what you are expecting (i.e. Apple can and probably does rename them while saving them to the Camera Roll).
You can check the metadata on the ALAssetRepresentation for the video to see if a suitable name or other identifier can be found in there. You might also be able to retrieve the raw data and hash it, but that would fail if Apple does any recoding or metadata alteration when saving the video. If your program itself downloads and saves the videos to the Camera Roll using writeVideoAtPathToSavedPhotosAlbum:completionBlock:, you could store the returned assetURL to remember the correspondence. Or you could save the videos to your app's local storage instead of to the Camera Roll, but that would prevent the user from managing the videos with Apple's photo application and such.

iPhone SDK:Saving a streamed audio file to Documents folder
iPhone: how to download media files and save them on device
I have been trying to figure out how to do this for most of the day, but I haven't been able to find much help. We have this multimedia app that allows users to view pictures, videos, and music/ringtones about the particular subject. I know you can save images using UIImageWriteToSavedPhotosAlbum and you can save a video file using UISaveVideoAtPathToSavedPhotosAlbum. But I can't figure out how to allow the user to save an audio file. All the files are stored within the app, so its not like I'm trying to stream or download them from the internet. Does anyone have any pointers on how to do this?
The official SDK only allows you to retrieve information with MPMediaLibrary, no write access.
Are there any easy solutions for saving a number of images into a video file in iOS?
Example: I have 300 frames all saved as separate images and want to turn them into a single video file (e.g., mp4) that a user could email or post on YouTube.
No support in iOS, you may have to use open source libraries such as ffmpeg.
I have many videos in .flv and .mp4 formats. I store then in one Windows folder and re-name after downloading so that it becomes easy to find one that I want to play.
It would be best if I can create thumbnail from one of the frames of video file.
Is there a program/utility in which I can open the .flv or .mp4 file, play, pause and take the screen/frame and set it as thumbnail of that file?
I did my best to find it on internet but failed hence thought to reach out to Gurus.
Thanks in advance,
Jay
I think ffmpeg and mencoder can do this
