Thank you very much for your kind replies and advices compn, Timo and
Roger.

I am at the very beginning of the journey , I've never worked with Dshow
before but I'm very excited to learn and develop. I will look through all
the materials given and start doing stuff as soon as possible.

  dont forget you can check other open source projects
  (videolan, virtualdub etc) and maybe copy how they do dshow video
  capture.

 Just don't copy and paste, since the VLC stuff [at least] is straight
 GPL and we'll need this one to be LGPL [so basically base it off of
 the MSDN not off the VLC code base, that's what I do].  Look forward
 to corresponding more through private email on the issue with you.

Hi,

I'm currently working on* dshow digital video capture* and it's really
interesting, even if I' m making slow progress, as I' m not familiar with
graphstudionext and DShow principles .

I decided to apply for another project as well, the *MPEG-4 ALS encoder**
project, *for two reasons, as suggested by a developer on IRC: it involves
more mathematical work and signal processing as well as giving mentors more
flexibilty and improving my understanding of ffmpeg.

I will start with the links in the project description and work my way up .
Any thoughts/ advices are welcome .

Regards,
Andrei

[FFmpeg-devel] GSoC '15 Introduction

2015-03-07 Thread Ilinca Andrei
   Hello!

   Short description:
   Full name : Andrei Ilinca
   IRC Handle: andrei_il / andrei__il
   Studies: Second year student at the Faculty of Automatic Control and
   Computer Science at the  Polytechnic Univ of Bucharest
   Github: https://github.com/ailinca

   I'll try to divide my introduction mail into two main parts:
   Background, why FFmpeg and why directshow digital video capture project.

   *Background*

   I'm Andrei, I'm a second year student at the Faculty of Automatic
   Control and Computer Science at the  Polytechnic Univ of Bucharest. This
   GSoC is my first opportunity to work with the open source community and I
   can say I'm thrilled!
I have experience working with C and I enjoy coding using this
   language.C was my language of choice both for academic purposes and for
   coding challenges like talentbuddy https://www.talentbuddy.co and
   codingame http://www.codingame.com. Currently, I m exploring other
   areas as well, such as developing a standalone Java app that tracks how you
   spend money or some simple game in C++ and Qt. While programming is my
   carrer choice, math was always my passion. Since Primary School I attended
   contests and got rewarded Localy ,CityWide and National. I enjoy solving
   various smart mathematical problems with applications in all areas of
   research.

  * Why FFmpeg?*

   Why FFmpeg?  Honestly, I did not start looking for a project on this
   GSoC having the fixed FFmpeg org in mind, I was just looking for a C
   project. Because there are plenty orgs, with plenty projects and it's
   difficult to choose one, having no previous experience. On short, I landed
   on your project page more or less randomly. But I stayed. And here's why.
   FFmpeg development involves something that I've always considered
   interesting and that is encoding/decoding information. While I was on your
   website, I asked myself how is voice converted to digital, how does it
   happen, which lead me to this
   
http://electronics.howstuffworks.com/gadgets/high-tech-gadgets/speech-recognition1.html
   . All in all, I find all this interesting, a lot of new notions to me, but
   it's definetly somnething I would see myself enjoying working on throughout
   the summer.

   *Why directshow digital video capture ?*

   Simply because It sounds really interesting and entertaining. I have
   some experience using Matlab and Simulink for converting from time-domain
   to frequency-domain and back, Bode  Nyquist Diagrams and I have basic

https://msdn.microsoft.com/en-us/library/windows/desktop/dd373406%28v=vs.85%29.aspx,
   and I believe this project suits me the best.

   I got the git code base cloned and started reading and documenting
   about it.
   I would like to work on the qualification task for this project but
   I need some more informations about it. How should I proceed further?
   I'll be around on IRC quite a lot, but I'll get in touch more once I
   start working on something. If you have any feedback or criticism, please
   do, it's appreciated!

   Sorry for the long-ish mail! It really seems like an interesting
   project and something I'm very enthusiastic about.
   Regards,
   Andrei

Hello,

This is my first qualification task submit for the *d**irectshow digital
video capture *project. In this http://i.imgur.com/zd47rP3.png link there
is my screenshot proving that I successfully made a filter graph using
graphstudionext that captures the video stream from a webcam and show it
on the screen . I am now working on the second part of the qual task, which
is adding an IPersistStream option to and from file for the dshow code base
for video module.

Roger Pack, thanks a lot for helping me out with this, your feedback has
been very useful!

Regards,
Andrei
