encode_write() mapped all return values from avcodec_receive_packet() into 0 or -1, which destroyed the AVERROR_EOF signal needed by the caller. The flush call in main() could never see AVERROR_EOF, so a successful encode always exited with a non-zero status. Let encode_write() return the original error code and have each call site handle the expected status: - Encoding loop: ignore AVERROR(EAGAIN) (need more input) - Flush path: ignore AVERROR_EOF (normal end-of-stream) This makes the control flow explicit and easier to follow for anyone reading the example.
