RTPSender

description

功能：将音视频数据转换成rtp包

usage examples

安装av库

pip uninstall av && pip install av --no-binary av

提供了四个转换函数，支持传入原始文件和字节数据两种方式，具体使用方式请参考下面的示例：

from pydub import AudioSegment
import cv2
from time import sleep, time

if __name__ == '__main__':
    ip_address = "10.253.101.36"
    # ip_address = "127.0.0.1"

    audio_16k_file = "/Users/a58/Code/python/rtp/audios/bgroup16k.wav"

    frame_size = (1080, 1920) # (width, height)

    rtpSender = RTPSender(ip_address, port, frame_size, hard_encode=False, open_log=True, days=7)
    rtpSender.stop()
    
    rtpSender = RTPSender(ip_address, port, frame_size, hard_encode=False, open_log=True, days=7)

            rtpSender = RTPSender(ip_address, port, frame_size, hard_encode=False, open_log=True, days=7)
            init_cnt += 1
            print("reinit rtpSender: ", init_cnt)
