I have a directory of bitmaps that are all of the same dimension. I would like to convert these bitmaps into a video file. I don't care if the video file (codec) is wmv or avi. My only requirement is that I specify the frame rate. This does not need to be cross platform, Windows (Vista and XP) only. I have read a few things about using the Windows Media SDK or DirectShow, but none of them are that explicit about providing code samples. Could anyone provide some insight, or some valuable resources that might help me to do this in C#? At the risk of being voted down, I'll offer a possible

how to Play numbers Of audio files at same time With AVAudioPlayer? Is it Possible to Play numbers Of audio files can play at same time using AVAudioPlayer? or any other way to play numbers of audio files at same time ? Thank You! Files with below formats can be played simultaneously on iPhone. AAC, MP3, and ALAC (Apple Lossless) audio: have CPU resource concern. Linear PCM and IMA/ADPCM (IMA4 audio): without CPU resource concerns. You just need to create a new player instance for every music file, that you want to play. Sample Code snippet: -(void)playSounds{ [self playSound1]; [self

I've written an MP4 parser that can read atoms in an MP4 just fine, and stitch them back together - the result is a technically valid MP4 file that Quicktime can open and such, but it can't play any audio as I believe the timing/sampling information is all off. I should probably mention I'm only interested in audio. What I'm doing is trying to take the moov atoms/etc from an existing MP4, and then take only a subset of the mdat atom in the file to create a new, smaller MP4. In doing so I've altered the duration in the mvhd atom, as well as the duration in the mdia header. There are no tkhd

I want to store a large number of sound files in a database, but I don't know if it is a good practice. I would like to know the pros and cons of doing it in this way. I also thought on the possibility to have "links" to those files, but maybe this will carry more problems than solutions. Any experience in this direction will be welcome :) Note: The database will be MySQL. Every system I know of that stores large numbers of big files stores them externally to the database. You store all of the queryable data for the file (title, artist, length, etc) in the database, along with a partial path
