Job Summary

Own hardware-accelerated video pipelines on ARM-based SoC platforms - encode, decode, transcode and streaming paths built on GStreamer and vendor codec interfaces, for multi-stream edge and enterprise devices.

Key Responsibilities

  • Design, build and optimize GStreamer pipelines for hardware-accelerated encode, decode, transcode and composition.
  • Integrate and maintain codec plugins and V4L2 stateful/stateless codec interfaces for H.264, H.265, VP9 and AV1 as supported by the platform.
  • Enable multi-stream, multi-resolution concurrency with defined latency, bitrate and throughput targets.
  • Implement zero-copy buffer flows between camera, video, GPU, display and inference stages.
  • Build and tune low-latency streaming paths (RTSP/RTP/WebRTC class) and container/muxing handling.
  • Profile and resolve pipeline stalls, dropped frames, A/V sync drift, latency spikes and memory bandwidth bottlenecks.
  • Develop custom GStreamer elements and plugins where platform capability is not covered upstream.
  • Define video KPI measurement methodology and contribute to automated video regression suites

Skill Requirements

  • 8-10 years in embedded multimedia / video software engineering.
  • Expert-level GStreamer - pipeline design, element and plugin development, negotiation, caps, queues, debugging with GST_DEBUG and pipeline graphs.
  • Strong C/C++ on embedded Linux.
  • Hardware codec integration experience via V4L2 codec APIs or vendor codec SDKs.
  • Solid grasp of video compression fundamentals - GOP structures, rate control, profiles/levels, bitstream basics for H.264/H.265.
  • Zero-copy buffer management (dma-buf / DMA heaps) and memory bandwidth awareness.
  • Performance profiling and latency measurement on constrained SoC platforms

Other Requirements

  • AV1 or VP9 hardware pipeline enablement.
  • WebRTC, RTSP server/client or adaptive streaming implementation.
  • Android MediaCodec / Stagefright / OMX stack experience.
  • Display pipeline, DRM/KMS and composition experience.
  • Upstream GStreamer contributions.
