Is there any API available by which I can embed my own images in a any Video file at certain points in the Video or between certain video frames ?
If not, I would like to study the formats of the files, e.g. study the format of an mp4 file and create the API myself. Please point me to any sites that reveals the MP4 files format that can be easily understood.
Please do not tell me the Applications already doing it. I want to do it myself through programming.
Any help is greatly appreciated.
Thanks!

I'm two days into researching this so I thought I'd post here. It looks like video recording software is usually written in C++ but my project requires C#. It's a WPF application and I just need it to save an mp4 locally. I don't need to upload to a server, I don't need to let the user pick a file location, I don't even need it to display the webcam feed as it's recording. All I need it to do is start/stop recording audio and video from a webcam/microphone and save it in a location that's determined by the code. I understand this may be broken down into steps like connecting to a webcam, connecting to a microphone, synchronizing them, encoding a video file, and saving it on the hard drive.
Are there any .NET classes that can help me with this? If not, can anyone recommend some libraries/frameworks/etc. that handle this sort of thing? I appreciate any help regarding how to do this. Thank you.
I am making an app in which I want to create pdfs out of the images I store in the Isolated storage. Many opensource libraries are available for solving the purpose but unfortunately none expresses their comparability with windows phone 8.
then I came across this link
the post explains about writing the pdf file by making the pdf header. But, this only creates a pdf with some text written in it. I, now want to add some images in it. How shall I proceed for the same?
I have found the answer myself. These are the links which would be very much helpful if you are looking to make a pff
with text and images without the usage of opensource libraries.

a bit of background:
this summer, i set myself a programming project,
where i want to make an E-jay clone(a program with simple drag-drop blocks which are little bits of music and beat to make a track)
now i dont really know where to start on the whole encoding music bit.
for example:
how does a sound file work?
how do i transform a piece of a sound file into a universal piece of sound information
how do i create a sound file from scratch
how do i add pieces of sound to a previously newly created sound file
im sorry if i seem like one of those guys that cant use google n stuff. but i have no experience with sound or anything on that part.
programming language: C#
ultimate goal: be able to encode a new mp3 file using small sound files which are inserted on certain points in the file to ultimatly make music
any help is appreciated,
thank you for reading my question.
I think you should check NAudio site - it has lots of examples.
Do some research into the MPEG compression standard, as you'll need to know about decoding as well as encoding. If you are going to be ambitious, maybe look into other audio file types as well.

I am newbie to c#. I have functionality of concatenating two or more video files using directshow.net. I have seen the documentation form http://msdn.microsoft.com/en-us/library/windows/desktop/dd375143(v=vs.85).aspx but i didn't understand how to start. I will be having two video files in the server in some folder. I want to combine those two video files and save as single video file. How can i do that using directshow.net. I am struct at this. Any help is appreciated.
DES can work good, but keep in mind it has been discontinued. Maybe this page describing how to append two wav files can help you get started. See the Time Line Model page on MSDN for an overview.
What I am trying to do is read the Pitch/Amplitude of one wave file, then increase the pitch of another wave file depending on the Pitch/Amplitude of the first. The second part should be simple enough for me. But what library do I need to use (and what method). It would be great if anyone can help. At the moment I am using the SoundTouch http://code.google.com/p/soundtouchnet/ library to up the pitch.
Any help or tips is appreciated.
Try using DirectSound. This tool allows you to do whatever with wav files. There are plenty of sources to find tutorials too.
