Worked on the deckerst/media-kit repository to enhance the stability of the Web Video Player by addressing a critical issue in error propagation. The solution involved modifying the error handling mechanism so that errors from the VideoElement are now emitted as data events within the stream, rather than being added to an error stream. This approach ensures that error messages are reliably passed downstream, improving both observability and fault handling during video playback. The work focused on Dart and web development, with a strong emphasis on robust error handling practices, resulting in a more maintainable and transparent streaming experience for end users.
