Opencv Videocapture fails to read http url videos
16 mars 2019, par Purav ZumkhawalaI want to read HTTP URL videos in my Ubuntu system without downloading them. I can do this in windows OS but when I try to run the same code in Ubuntu using the same opencv VideoCapture method it fails to get any frames.
Why is this so ?
I have used same opencv version in both Ubuntu and Windows, can anyone guide me towards a workaround, a tutorial using which I can compile opencv and stream url videos or any other library that supports this functionality in Ubuntu ?
I have tried almost everything but with no productive result which has led me to finally ask this as a question.

From this output i want to store : "HP True Vision HD Camera" (first video output) in a python variable.


Is this possible ?


I am trying

pipe = subprocess.run(ffmpeg_command,stdout=subprocess.PIPE,stderr=subprocess.PIPE,bufsize=10**8)
output = pipe.stdout
lines = output.splitlines()
for line in lines:
 if line.startswith("[dshow @"):
 if "(video)" in line:
 camera_info = line.split("\"")[1]
 print(camera_info)
