Worked on enhancing test diagnostics for the v210enc encoder path in the ossrs/ffmpeg-webrtc repository, focusing on improving the reliability and clarity of automated quality assurance. Refactored the v210enc checkasm tests in C to replace memcmp-based buffer checks with the checkasm_check function, enabling more detailed diagnostic output, especially when tests are run in verbose mode. This approach improved the efficiency of debugging and made it easier to isolate regressions by providing richer failure information. Leveraged skills in debugging and testing to strengthen the test suite, supporting more reliable encoder validation and reducing the time required to identify issues.
