Hi Cesar, I stumbled across this project after I found the thread 
http://www.aforgenet.com/forum/viewtopic.php?f=2&t=2695 where you had submitted 
patches to support H264. 2 years later, it is a pity, the main trunk still does 
not have H264 support. 

We are currently using a modifed AviWriter.cs in our open-source 
screenshot/screencast application ShareX. We write a collection of images to 
avi container. Using x264VfW we create a H264 compliant stream however because 
it is in an avi container, we then have to mux it to mp4 container using 
ffmpeg. Therefore it is a two-step process. Ever since, we've been looking for 
a way to directly write to a mp4 container. I found out the hardway that 
AForge.NET does not support H264 and it does not play in HTML5 pages. You 
already know that - if you click on

5.mp4 it won't play but if you download it, it will play. 

Looks like we have similar interests in terms of building the ultimate 
screenshot/screencast application. I welcome you to try ShareX source from 
https://github.com/ShareX/ShareX/commits/master along with 
https://docs.google.com/document/d/1_Mud2dKbbZFRNED0tX4pay4_d5vOYkviiiaV0y52G_s/
edit to see our journey towards directly writing to mp4. 

If you are interested in contributing to ShareX i.e join forces, let me know :)
