I am trying to upload video created using MS Expression Encoder 4 to YouTube, but after processing any video is played in 3 seconds.
Any ideas? Is it problem of encoder configuration or YouTube?
Thank you.
I was running into the same issue when I encoded a video using the Expression Encoder SDK and uploading the videos to YouTube. I didn't experience the issue when I used the BaselineH264VideoProfile video profile. I also think the one that outputs WMV didn't experience the issue as well. Not sure if this will help you, but if not hopefully someone else.
Thanks,
James
FYI, I've experience similar 'short video' issues with EE 4. I noticed that 5 miniute vidoes were actually only 15 seconds or so long. Doesn't happen all the time; about 20%. After turning disabling audio profile, the problem went away. Experimenting just a bit more I found I could reliably repoduce this issue by rapidly changing audio volume while screen capturing... No idea why but the capture definitely freezes

I am new to iPhone Development. I need to capture video. While I'm capturing video it display on server too. Something like live streaming.
Anyone have idea from where I should have to start for this functionality?
Thanks in Advance.
Your question seems similar to this
Xcode ios: Streaming of video file while recording and removed redundant personal statements
First Half Solution
Using AVFoundation you can get video Buffer/frames while recording.
Second Half
But for uploading i didn't find any solution
There is Input Stream option there in iOS APIs but it need some file path. but as video is not recorded we didn't have any path.
Edit 1
Here is Best Example for AVFoundation provided by Apple, you can start with
I recommend you to use wowza wowza.com/https://www.wowza.com, it has all the features, from live stream, video on demand and etc.
I am trying to get the duration of a video taken with the camera using UIImagePickerController on the iphone, has anyone found a solution to this?
Thanks

You can now do this using AVFoundation you can make your movie into an AVAsset and then check the duration property
Oh, why, hello hopelessly obsolete answer. I'm afraid you're only left here as historical evidence that yes, before iOS 4 if you wanted to do anything remotely interesting on a recorded video (besides playing it) you had to implement the processing yourself.
I don't know of any framework function to do so, so I'm afraid you'll have to parse the video container yourself (which by the way, is QuickTime/.mov) to extract this info. It's not like it's not documented. Luckily since the provider is known, you can trust all info to be truthful, which you can't assume of random videos found on the web.
I have a wav file that was working fine. It is played using the AudioServices methods. Suddenly it stopped working. The weird thing is if i change he wav file to a different one that works. Any idea what is going on? The non working sound is slightly longer (still <10seconds) but it was originally working so I just can't figure it out.
Any suggestions of what to try would be most appreciated. Thanks :-)
AudioServices won't play sounds longer than 5 seconds. Playing longer sounds will require using a different Audio approach.
Here's a decent example of playing sounds with another method:

I am working on an application that will stream music from a server of mine from an iPhone application.
This is my first iPhone app so I am a bit confused :
What would be the best way to do
this?
Is there something already built in
that I could use, like a MP3 player
that I just need to point toward the
correct server?
Do I need a streaming server to do
so?
I'm relatively new to Objective-C/Cocoa (touch), but I have read an article on the cocoawithlove site titled "Streaming and playing an MP3 stream" and tested the sample code on my iPhone and it works perfectly. I don't know about the licensing or anything, if you would be able to use it, but I'm sure someone or even you can figure that out.
Sorry again for not being able to provide any more information or even a link. This is my first answer on SO and cannot post hyperlinks :(

I am getting raw aac data from web stream and try to put it in ADTS frame in order to play it on iPhone.
It works for 10 seconds then sound stops and restart but seems accelerated or mixed with others audio data.
Quicktime and others audio app are unable to open my file.
It seems my ADTS header is wrong but I am unable to find where.
Is there an ADTS guru there which could be help me ?
Here my adts file
Thanks a lot for your help.

PS : do you know a tool to check and report problem in audio file ?
Found.
Frame size was not valid.
Also I found afinfo on os x which is very useful to get file info.
