我是Python的初学者,想建立一个类似于的视频日记 电影“Avartar”。我想使用OpenCV。录制我网络摄像头的视频流已经准备就绪,但如何同时保存网络摄像头的视频和音频? 顺便说一句:我正在使用Linux和python 2.7
我目前的视频录制代码:
#!/usr/bin/python
time = localtime()
s = "%02i:%02i:%02i_%02i-%02i-%02i" % (time[3],time[4],time[5],time[2],time[1],time[0])
global fn
fn = "%02i_%02i_%02i__%02i_%02i_%02i" % (time[3],time[4],time[5],time[2],time[1],time[0])
recordingtime=str(s)
videodir="./Videos/"
# Set video settings
capture = cv.CaptureFromCAM(0)
fourcc = cv.CV_FOURCC('M','J','P','G')
fps = 25
w, h = 720, 540
stream = cv.CreateVideoWriter(video.avi", fourcc, fps, (w, h))
# recording time
recordingtime = 20
recstart = int(time())
while True:
now = int(time())
recdiff = now - recstart
counter = recdiff - recordingtime
if counter <= 0 :
# start timer
rectime = recordingtime
frame = cv.QueryFrame(capture)
# write stream
# Display text
## color settings for text
r=255
g=255
b=255
## Text position
tx = 450
ty = 330
font = cv.InitFont(cv.CV_FONT_HERSHEY_COMPLEX, .7, .7, 0, 1, 20)
cv.PutText(frame, recordingtime, (ty,tx),font, (b,g,r))
cv.WriteFrame(stream, frame)
## Farbdefinition des eingeblendeten Textes
r=255
g=0
b=0
## Textposition
tx = 450
ty = 50
font = cv.InitFont(cv.CV_FONT_HERSHEY_COMPLEX, 2, 2, 0, 4, 20)
cv.PutText(frame, str(counter)[1:], (ty,tx),font, (b,g,r))
# show window
cv.ShowImage("capture", frame)
# move window
cv.MoveWindow ("capture", 550,400)
key = cv.WaitKey(10)
if key & 255 == 27:
sys.exit()
else :
break
提前感谢您的帮助。
干杯 微米。

遗憾的是,opencv
中不支持音频流
