bitmaps to mp4

[shawnning]

Hi, Everyone

I am writing a program to convert thousands of bitmaps into a mp4 file. I am currently convert them into MS AVI file and then use handbrake to convert avi to mp4.
Is there an interface in handbrake can read bitmap and generate mp4 file directly? If not, How difficult is it to implement such a thing? Can anyone point to me where to start?

I know ffmpeg and libavcode has such a function, but the code is such a mess. I have quickly checked the handbrake source code and it is much more elegant.

Thanks
Shawn

Most nonlinear editors convert image sequences to video files with ease.
I don't see a big need to write separate software or scripts when NLEs do it better.
Just my thoughts, you understand.

Thanks for the reply.
Can you name a few? Open sourced as I need integrate that piece of code, from bitmap to mp4

I'm sure AviSynth / MeGUI will do everything you need. All you need to do is write a simple script.
I don't use any nonlinear editors that are "open-sourced" so I can't help you there.
They will all take image sequences to mp4 without any additional "code."
