View proposal in schedule


To provide a slightly deeper dive into the working of stagefright to give a kick start to porting and extending multimedia functionalities on Android.


Will be describing the various blocks of stagefright and how they interact with each other taking rtsp and file playback as examples. Based on availability of time for the talk and the interest, i will also be covering porting stagefright with integration with overlay, camera and openmax codecs. Understanding of Openmax and some other multimedia framework will help in following the talk better.

Speaker bio

Primarily a Multimedia frameworks engineer. During the 8 years of work, i have dealt with writing two proprietary multimedia frameworks, integrated various codecs, tuned performance, worked on board wake up procedures and have also worked with couple of device drivers.

    That’s an awful lot of upvotes for a proposal with so little detail.

      Hi Kiran, the votes are from people whom i know. I had shared the outline of the talk with them. I am working on the slides and hope to put it up soon.

        Are they coming to the event? In future events, we’ll only count votes from folks with a ticket to the event (the tech isn’t in place for this event).

          True. That will definitely be a good idea.
