Dickson City, PA rick@badfroggy.com | 818.455.5916 Mathematically minded Video Software Engineer with 9 years of experience coding video features for Mobile Apps and DVD/Blu-ray products, backed by a very strong academic record in Math, Computer Science, and Statistics. Deep interest in generating low-level code and designing algorithms to drive sophisticated processes such as GPU shaders and MP4 multiplexers. Formats HLS, M2TS, MP4, H.264 Video APIs FFmpeg, AVFoundation, VideoToolbox, MediaCodec, OpenMAX IL, Stagefright Graphics OpenGL ES, GLSL, Unity3D, CG shaders Languages C++, C, Objective C, C#, Java ME/SE, Actionscript 3, JavaScript Other Android NDK, Linux, Xcode, Eclipse, Unity3D, git, svn
“The Renderer” – Multimedia pipeline used to filter, combine, and transcode incoming content on mobile devices. The GPU and video codec hardware are used for fast encoding, and a seamless preview experience. The renderer is a cross-platform C++ library using OpenGL ES 2.0. It uses pluggable, platform-specific modules where necessary for decoders and encoders (AVFoundation, MediaCodec, and OpenMAX), keeping code duplication to a minimum. Implemented custom OpenGL ES 2.0 color conversion shaders, allowing video color formats (YCbCr) to be converted to screen format (RGB) and vice versa to convert filtered content for use by the encoder.
Acorn Anxiety – Created using Unity3D, with shaders written in the CG shader language. CG is used to generate the appropriate code for various rendering systems, such as OpenGL and DirectX. Sound Visualizer – Android app written using the NDK and OpenGL, which displays the frequency spectrum calculated from microphone audio samples. The goal of this application was to better understand the process of publishing an application, from a broader perspective than software development alone.
Android HLS/M2TS Player – ABC and Disney use this library in their Android applications: “Watch Disney”, “Watch Disney Junior”, “Watch Disney XD”, “Watch ABC”, and “ABC Family”. Verizon acquired Uplynk to expand their Digital Media Services group in November 2013. I developed this library to support HTTP Live Streaming on Android 2.3 and above, using hardware decoders through the OpenMAX IL and Stagefright APIs, in addition to the Fraunhofer AAC library. Several unique challenges presented themselves; primarily involving compatibility issues between different hardware H.264 decoders. Other challenges included non-standard frame formats output by the decoder, “secure decoders” on Android 2.3 which do not make pixel data available, and minimizing the total file size of the library while maintaining several device-specific libraries.
Virtual Vault (M2TS) – Enables viewers to stream SD video content to Blu-ray players. MagicMenus – Speech recognition iPhone app to control Blu-ray discs, using PocketSphinx speech recognition library to convert voice to text, then customizing software to send commands to Blu-ray players (activating main feature, bonus content, etc.).
Blu-ray Streaming – Created an M2TS adaptive streaming system for Blu-ray that works within the rigid constraints of the Blu-ray format. Logic Puzzle "Hint" Engine – Linear algebra engine generating shortest-path "next move" hints for solver. Playback Library – Constructed first-generation code library that powered content playback, screen switching, and order of playback for various video content.
Elementary Stream Comparison – Developed an M2TS elementary stream comparison utility to cut costly QC overtime trend on content with many audio and subtitle streams. Blu-ray File Editing Utility – Created utility suite for viewing/editing Blu-ray files that became the go-to resource for diagnosing problems unable to be identified through the standard authoring tool.
