一、所需資源
1、nginx的Gryphon版本，它內(nèi)部已經(jīng)集成了rtmp的推流編譯(nginx-Gryphon)
2、服務(wù)器狀態(tài)檢查程序stat.xsl（nginx-rtmp-module）
3、ffmpeg（ffmpeg）
4、VLC（VLC）
二、安裝
1、將下載好的nginx 1.7.11.3 Gryphon解壓修改文件名為nginx-1.7.11.3-Gryphon，絕對(duì)路徑中不能有中文，必須全為英文！
2、在根目錄中的conf文件夾中，若有nginx.conf文件，直接進(jìn)入修改；若無(wú)，則創(chuàng)建一個(gè)。
3、在nginx文件中，將以下內(nèi)容粘貼。
#user nobody;
# multiple workers works !

}
注：rtmp中的“application live” ,application+空格+live，live即使訪問(wèn)路徑，如localhost:1935/live。
4、在nginx.exe所在的目錄，即根目錄下，進(jìn)入cmd窗口，輸入nginx.exe或.\nginx.exe，啟動(dòng)nginx。
5、可以直接瀏覽器輸入localhost驗(yàn)證是否啟動(dòng)nginx，若出現(xiàn)nginx的主頁(yè)面，則成功。
6、將服務(wù)器狀態(tài)檢查程序解壓，放到nginx根目錄下。
7、將ffmpeg解壓后，將其bin目錄添加環(huán)境變量。
8、安裝VLC
三、ffmpeg推流
ffmpeg推流是為了確定nginx的1935端口已打開并運(yùn)行rtmp推流功能，以排除故障等問(wèn)題。
1、在測(cè)試視頻所在文件夾打開cmd窗口，輸入指令 ffmpeg.exe -re -i .\視頻名.mp4 -vcodec libx264 -acodec aac -f flv rtmp://127.0.0.1:1935/live
2、若出現(xiàn)以下畫面則推流失敗，是因?yàn)閚ginx的1935端口未開啟，或是rtmp未推流。
3、若出現(xiàn)以下畫面，則成功，frame, fps等信息會(huì)不斷地變化。
4、打開VLC，在左上角媒體中選擇 打開網(wǎng)絡(luò)串流 ，在網(wǎng)絡(luò)URL中輸入rtmp://127.0.0.1:1935/live，點(diǎn)擊播放。
5、若是顯示出視頻，則成功。文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-439094.html
四、無(wú)人機(jī)rtmp推流
1、保證電腦和無(wú)人機(jī)遙控器（或遙控器連接的手機(jī)）在同一局域網(wǎng)中（即同一路由器或熱點(diǎn)）。
2、電腦確認(rèn)ip地址，打開cmd窗口輸入命令ipconfig，確定電腦ip地址。
3、無(wú)人機(jī)進(jìn)入自定義直播功能中，輸入地址，一般為 rtmp://192.168.x.x:1935/live 或 rtmp://10.0.x.x:1935/live。
4、打開VLC，在左上角媒體中選擇 打開網(wǎng)絡(luò)串流 ，在網(wǎng)絡(luò)URL中輸入與 3 中同樣的ip地址，點(diǎn)擊播放。
5、若顯示出無(wú)人機(jī)畫面，則成功，一般延遲在 3~10s 內(nèi)。（我是成功了，哈哈哈哈哈?。?br> 注：若無(wú)人機(jī)無(wú)法傳輸視頻，那么把Windows系統(tǒng)的防火墻關(guān)閉再試一試。文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-439094.html
五、Python獲取無(wú)人機(jī)實(shí)時(shí)視頻
import cv2
import time
if __name__ == '__main__':
# 無(wú)人機(jī)rtmp視頻流url
video_path = "rtmp://192.168.x.x:1935/live"
# opencv獲取視頻流
capture = cv2.VideoCapture(video_path)
while True:
fps = 0.0
t1 = time.time()
# 讀取某一幀
ref, frame = capture.read()
fps = (fps + (1. / (time.time() - t1))) / 2
print("fps= %.2f" % (fps))
frame = cv2.putText(frame, "fps= %.2f" % (fps), (0, 40), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 255, 0), 2)
cv2.imshow("video", frame)
c = cv2.waitKey(1) & 0xff
if c == 27:
capture.release()
break
print("Video Detection Done!")
capture.release()
cv2.destroyAllWindows()
