Re: [FFmpeg-devel] GSoC '15 Introduction
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!

Re: [FFmpeg-devel] GSoC '15 Introduction
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.

I got the git code base cloned and started reading and documenting about it. great! being able to find docs, play in git and do it all by yourself is a very useful skill to have. -compn ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
