How to implement without library--

const uint16_t phase[2] = {510,0};

#define LED1 19
#define LED2 21
#define LED1_OFF digitalWrite(LED1, HIGH)//关灯1
#define LED1_ON digitalWrite(LED1, LOW)//开灯1
#define LED1_PWM digitalWrite(LED1, !digitalRead(LED1))//灯1闪烁
#define LED2_OFF digitalWrite(LED2, HIGH)//关灯2
#define LED2_ON digitalWrite(LED2, LOW)//开灯2
#define LED2_PWM digitalWrite(LED2, !digitalRead(LED2))//灯2闪烁

int freq1 = 39000; // 频率
int channel1 = 0; // 通道0，共16个通道，015
int resolution1 = 11; // 分辨率，取值020，duty最大取值为2^resolution-1

int freq2 = 39000; // 频率
int channel2 = 0; // 通道1，共16个通道，015
int resolution2 = 11; // 分辨率，取值020，duty最大取值为2^resolution-1

void setup()
{
ledcSetup(channel1, freq1, resolution1, .hpoint ); // 设置通道0
ledcSetup(channel2, freq2, resolution2 ); // 设置通道1
ledcAttachPin(LED1, channel1 ); // 将通道0与引脚19连接
ledcAttachPin(LED2, channel2 ); // 将通道1与引脚22连接
}

void loop()
{
// 逐渐变亮
int dutyCycle = 512;
{
ledcWrite(channel1, dutyCycle); // 输出PWM
ledcWrite(channel2, 1023 - dutyCycle); // 输出PWM
delay(5);
}
}

Not an issue with the library, so converting to discussion.
Maybe you could try something like this ...

#include "driver/ledc.h"

const uint16_t phase[2] = {510, 0};

#define LED1 19
#define LED2 21
#define LED1_OFF digitalWrite(LED1, HIGH)//关灯1
#define LED1_ON digitalWrite(LED1, LOW)//开灯1
#define LED1_PWM digitalWrite(LED1, !digitalRead(LED1))//灯1闪烁
#define LED2_OFF digitalWrite(LED2, HIGH)//关灯2
#define LED2_ON digitalWrite(LED2, LOW)//开灯2
#define LED2_PWM digitalWrite(LED2, !digitalRead(LED2))//灯2闪烁

int freq1 = 39000; // 频率
int channel1 = 0; // 通道0，共16个通道，015
int resolution1 = 11; // 分辨率，取值020，duty最大取值为2^resolution-1

int freq2 = 39000; // 频率
int channel2 = 0; // 通道1，共16个通道，015
int resolution2 = 11; // 分辨率，取值020，duty最大取值为2^resolution-1

int speedMode = 0;
int dutyCycle = 512;

void setup()
{
  ledcSetup(channel1, freq1, resolution1); // 设置通道0
  ledc_set_duty_with_hpoint((ledc_mode_t)speedMode, (ledc_channel_t)channel1, dutyCycle, phase[0]);

  ledcSetup(channel2, freq2, resolution2 ); // 设置通道1
  ledcAttachPin(LED1, channel1 ); // 将通道0与引脚19连接
  ledcAttachPin(LED2, channel2 ); // 将通道1与引脚22连接
}

void loop()
{
  // 逐渐变亮
  {
    ledcWrite(channel1, dutyCycle); // 输出PWM
    ledcWrite(channel2, 1023 - dutyCycle); // 输出PWM
    delay(5);
  }
}
