MediaTek 520 MVPU encounters corrupted JPEG output with GStreamer
An engineer reported encountering corrupted JPEG output when attempting hardware-accelerated JPEG encoding on the MediaTek 520 MVPU using GStreamer v4l2 plugins. The corruption occurs for both file-based and live camera sources, though a test source pipeline works correctly. The issue indicates a potential bug or configuration problem within the platform's video processing unit or GStreamer implementation.
Key Takeaways
- Corrupted JPEG output affects hardware-accelerated encoding on MediaTek 520 MVPU.
- The issue manifests when using GStreamer v4l2 plugins with file-based and live camera inputs.
- A test source pipeline provided by MediaTek's AIOT documentation functions correctly, suggesting specific input or configuration dependency.
- The MediaTek 520 MVPU is running AIOT version v25.1.1.
Why It Matters
Issues with hardware-accelerated encoding directly impact device performance and efficiency, particularly for edge AI applications relying on the MediaTek 520 MVPU. Such bugs can delay development cycles and increase integration costs for product developers using this chipset for video processing. This report highlights potential inconsistencies in hardware acceleration capabilities or GStreamer plugin compatibility. Streaming video engineers should monitor MediaTek's response and updates regarding the 520 MVPU's GStreamer support to ensure stable, performant encoding pipelines.
