I am trying to write a program that adds an SMPTE timecode track to a QuickTime movie, so that I can use this movie in professional editing applications like Final Cut or Avid.
There is a nice example from Apple that explains how to do this with the QTKit-Framework: Code Sample
But since QTKit is 32-bit and AVFoundation will be its 64-bit Replacement, I need to know if this is possible with AVFoundation?
I just pulled an iPhone video into FCP, and it has valid NTSC timecode. It just starts at 01:00:00:00 for each clip. If you want a time-of-day type timecode, then I would suggest generating a timestamped THM file that can be used by programs like qtChange to embed the timecode to QT files. This is how to manage timecode in Canon 5D workflows.

I have the Mini210 board, I Installed both WINCE6 & Android on it.
I can not play any video, Like MP4 ,264 or AVI on it.
it does not recognize any of this formats.
I looked at It's BSP on wince, it only have two drivers. and does not have any driver for MFC( multi format video codec).
any Idea how to fix this problem?
In WinCE it is I believe your responsibility to select the required video format support in Platform Builder
I have implemented a MPMoviePlayer in my app and when I try it with a sample video in .mov format it works well. But when I change movie-clip to a .mP4 or m4v it does not work, the app crashes (I have tried with a bunch of different movie-files. What can be wrong? Does anyone else have this problem?
I don't know if this answers your question, but I did a quick search on supported file formats.
Another S.O. Answer:
Supported Formats
This class supports any movie or audio files that already play correctly on an iPod or iPhone. This includes both streamed content and fixed-length files. For movie files, this typically means files with the extensions .mov, .mp4,.mpv, and .3gp and using one of the following compression standards:
1. H.264 Baseline Profile Level 3.0 video, up to 640 x 480 at 30 fps. (The Baseline profile does not support B frames.)
2. MPEG-4 Part 2 video (Simple Profile)
If you use this class to play audio files, it displays a white screen with a QuickTime logo while the audio plays. For audio files, this class supports AAC-LC audio at up to 48 kHz, and MP3 (MPEG-1 Audio Layer 3) up to 48 kHz, stereo audio.
So that would be my guess why :)
Coulndt you just convert to MOV ?

For a university project i'm working on a DJ mixing app. I'm essentially tackling this project from a 'teach yourself from scratch by googling everything and analysing pre existing source code' type of way so go easy.
I have looked at the Mixer Host sample project from apple found here: http://developer.apple.com/library/ios/#samplecode/MixerHost/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010210
I can't work out how to replace the pre selected audio files (guitar + beat) with a song URL from the iPod library selected from a media picker, or, in this case - 2 media pickers.
Is it a case of grabbing the URL of the iPod library song selected and putting in place of the URL of the preselected audio file?
If someone could point me in the right direction, tell me how i'm completely going about this the wrong way, or even do the coding for me (joke), it would be greatly appreciated.
You can't actually simply stream from the ipod library; you need to copy the files into the documents directory of the app.
try this: http://www.subfurther.com/blog/2010/12/13/from-ipod-library-to-pcm-samples-in-far-fewer-steps-than-were-previously-necessary/
You can use third party libraries to play a iPod library songs using AudioUnit. The below link is useful to you

I am creating an iPhone application, which can play many media formats. I am not able to play AVI file format, where as I am able to play other formats (for e.g. MP3, MP4, MOV etc). When I try to play AVI, it shows black screen and display is hidden. Any suggestions on what I can do to fix this issue?
Take a look at this tutorial on playing video with ffmpeg and SDL, both available for the iPhone.
An ffmpeg and SDL Tutorial or How to Write a Video Player in Less Than 1000 Lines
It's written in C, but consider it pseudocode, and adapt it in Objective C accordingly.
.avi is a container format, not a specific audio/video codec. Depending on the contents of the .avi container, it may or may not be possible to decode the video on an iOS device (due to hardware limitations). If it is possible to decode the video in real time, you may have some luck using the libav (aka ffmpeg) library to decode it.
I want to make simple project which play flash video file from online.
I've searched some articles and read carefully.
But I can't understand, how to play flash video files on iPad by Code.
So I need help from you.
Please.
Simply put, without being jailbroken, No you cannot.
The closest thing to being able to view flash in iOS is Frash, and I am not even sure if it is actively being developed or supported any more.
You can always check out the open source project for Frash. by Comex.
All IOS devices don´t support Flash player, but is be possible to use a Javascript or HTML5 player for video.
No, iWhatever's currently do not and to the best of my surfing knowledge, have no intention of supporting flash format due to some argument between apple and adobe.
At the end of the day, the Flash video format is a container for a movie that’s been compressed by some codec. If you can get to the source file, you know the format of the container, you know the codec that was used to encode the video, and you know how to write code to convert that into audio streams and video frames, then yes, you can play Flash videos on the iPad.
So, to recap:
Get the Flash video file.
Get to the encoded video data in the Flash file.
Decode the video and convert it, either into raw audio and video or to another format that the iPad can play.
Play the result of #3.
Needless to say, this is quite the endeavor. It’s better to download the movies to your desktop and convert them there before loading them into your application.
Yes you can! The question is whether or not you can play the video itself not whether or not ipads support flash player.
the answer is this.. new versions of "flash video" have a f4v file extension. These videos are basically a h.264 mp4 files. You "may" be able to play it in an ipad simply by renaming it to .mp4
If that doesn't work then use a utility like Miro to convert your "flash video" to a format that your ipad will accept. http://www.mirovideoconverter.com/
