Worked on the ossrs/ffmpeg-webrtc repository to enhance the stability and portability of real-time media processing on ARM architectures. Addressed a prototype inconsistency in the ARM swscale path by constifying the dstStride parameter within the rgbx_to_nv12_neon_16_wrapper function, aligning it with related functions to prevent assignment errors and build issues across platforms. Utilized C and ARM Assembly to implement this targeted fix, ensuring improved cross-architecture compatibility and reducing the risk of runtime issues. The work involved careful refactoring and thorough documentation, demonstrating attention to code quality and collaborative development practices within the context of open-source media workflows.
