Developing and debugging applications leveraging hardware-accelerated video decoding often requires access to specific hardware, creating a significant barrier to early development and continuous integration. This talk introduces a new V4L2 decoder implementation that provides a software backend, effectively emulating a hardware decoder. This allows developers to write and test their GStreamer pipelines on generic systems, significantly accelerating development and improving portability. This talk examines the design choices and implementation details of this new decoder.
