PROFILE

João Neves

Worked on the FFmpeg/FFmpeg repository to enhance the reliability of RLE-based decompression in EXR and HDR codecs. Focused on improving error handling by ensuring that errors from the rle() function are properly propagated to the rle_uncompress() caller, which reduces the risk of silent data corruption when processing malformed input. Addressed a bug in the pixel count decrement logic to guarantee complete pixel processing during decompression. Utilized C programming and algorithm optimization skills to align with FFmpeg’s error-handling strategies, resulting in more robust video processing pipelines and improved data integrity for workflows relying on RLE-encoded media assets.

In April 2026, the FFmpeg/FFmpeg work focused on hardening RLE-based decompression paths in two codecs (EXR and HDR decoding). The delivered patches improve robustness, correctness, and error visibility, with direct business impact on data integrity and playback reliability for formats that rely on RLE encoding. The changes are aligned with FFmpeg’s error-handling strategies and reduce the risk of silent data corruption when encountering malformed input. This results in more reliable decoding pipelines for HDR and EXR assets, better stability in media processing workflows, and clearer maintenance signals for downstream consumers.
