• One of the first members of the offshore L4T (Linux for Tegra) team in Pune, India.
• Spearheaded the initial efforts on the L4T platform to resolve various build issues and get the multimedia components up and stable.
• Fix critical issues in the AV playback / Camera pipelines ranging from AV synchronization, buffer management to memory leaks and overall stability & performance across various multimedia stacks
• Designed, developed and maintained a comprehensive AV playback module called "nvgstplayer" with rich feature suite (such as network streaming, complex seek types) targeted for stress-testing the multimedia engines on Tegra platforms running L4T.
• Fixed few Pulseaudio & ALSA driver issues on L4T.
• Designed, developed and maintained the GStreamer Camera Capture plugin with various feature-rich controls. Also evaluated the V4l2/DMABuf support for V4L2 driver on Tegra.
• Evaluated & implemented a first-cut POC implementation of Wifi Display (middleware-level) on L4T platform.
• Worked on the middleware bringup of the Multimedia Stack on the Wifi-HDMI dongle, for low latency Game Streaming to TV Sets, based on Miracast at HQ in Santa Clara, California.
• Developed the Media Pipeline for Skype Audio/Video call (ARM binaries from Skype SDK) on L4T (POC implementation)
• Briefly worked on stabilizing the X.Org Video Extension on Tegra X.org driver for non-standard video resolutions and achieve seamless playback with out-of-the-box applications such as Totem, VLC Media Player running on standard Ubuntu rootfs on L4T.
• Oversaw the development of GStreamer plugin for accelerated video processing using the native 2D engine library on Tegra platform. This helped resolve the colorspace compatibility (mainly alignemnt) issues between decoders and the renderers, whilst increasing the overall playback performance.
