I'm making a video player for iOS Devices. I use a ffmpeg libraries to play the video files. I see the problems that have other video players in the App Store with the AC3 sound support.
I want that my video player don't works with AC3 sound. I'm looking for arguments in the compile script ffmpeg libraries like a --enable-gpl and --enable-nonfree, but not works.
I read the licenses of ffmpeg libraries several times and I think that I don't understand well.
Can someone explain how to do this?
Just add --disable-decoder=ac3 to ffmeg configure arguments.

I work on iOS and I want to play many audio files, one after the other, without break, like it was an unique audio file.
When the audio player reads the first audio file, I don't have the next audio files, i need to update the queue, while playing.
Is it possible ?
I insist on "without break"
Thanks for help !
It is possible, have a look at StreamingKit

I have a 3.5mm to IR sensor to connect to my headphone jack. I want to know if there's a way to create a basic app for my TV that will control it's Volume, Power On/Off, input, and number pad. I've kept researching for about a week now on how to do this, but haven't found an answer. Can someone help me?
Yes is it possible, you only need an application what play wav files.
Or jsut a file browser.
But you can find a plenty of applications and tutorials and details all over the internet.

I would like to distribute some music files with my application.
What is the way to add a media from the application folder to the media library?
Unfortunately no way to write to Music Library.
However you can add the files to Bundle and play from there and copy to Document directory. You can't change anything in the Music Library, only read permission is granted for third-party libraries.

If i record audio in noisy background and then compare recorded audio file with local saved audio file to check both are same song are not ? In iPhone
How Shazam and Sound Hound app works to generate Fingerprint of recorded audio in iPhone?
can anyone explore knowledge on algorithm to generate Fingerprint from audio file in ios.
Thanks
The fast (but possibly not very helpful) answer is: They probably do a Fourier Transform of the audio and compare. If you have never heard of Fourier before, you may want to find an API for it - the transform itself is not a programming problem, it's a math/signals problem.

Just by messing around a little it seems that the video stream is not ascii. i tested by downloading the stream. It would be insane if it was. Theres so many videos. So that couldnt be it. Youtube seems to not work with javascript disable (not counting mobile if true).
How is it being done? is it javascript magic? is the SWF running the video through a filter in realtime? (I doubt its a native filter so how is the filter compiled) its really cool. I cant imagine how this is running realtime yet it is!
MPlayer uses AALib for this type of effect. YouTube have probably ported it to ActionScript.
