Whishow

一款基于python的音视频在线播放器
在这里插入图片描述

1. 安装

pip install whishow

2. 用法

在这里插入图片描述

示例 1: 简单上手

cmd:
    python -m whishow <video_path_or_url>
e.g. 
    python -m  whishow rtmp://mobliestream.c3tv.com:554/live/goodtv.sdp

示例 2: 基于python多线程流处理和流播放

from whishow import STREAM,PLAY
import keyboard
import threading

# init the stream reader, named stm.
stm = STREAM()
stm.init_state(url=url,
                cache_size=10*60)
# init the whishow player, and connect the audio/video stream of stm.
ply = PLAY()
ply.init_state(start=0,
                chunk_size=1,
                video_frame_shift=20,
                audio_fps=stm.AUDIO_FPS,
                video_fps=stm.VIDEO_FPS,
                Q_audio_play=stm.Q_audio_play,
                Q_video_play=stm.Q_video_play,
                asr_results=[])

# thread-0: esc for exit
def engine():
    while 1:
        if keyboard.is_pressed('esc'):
            print("exit ..")
            break
        time.sleep(0.1)
    stm.running = False
    ply.running = False

# thread-1: stream reader
def stream():
    stm.read(video_dst_frame_size=video_dst_frame_size,
            is_play=True,
            is_asr=False)

# thread-2: stream palyer
def play():
    ply.run(show_subtitle=False)

p0 = threading.Thread(target=engine,args=())
p1 = threading.Thread(target=stream,args=())
p2 = threading.Thread(target=play,args=())

p0.start()
p1.start()
p2.start()

p0.join()
p1.join()
p2.join()
