  • How to fix opencv python cv2.VideoCapture rtsp onvif "nonmatching transport in server reply" error ?

    28 juillet 2022, par Projetos Prince Tower

    I am on Windows and using Python 3.6.4. I've installed OpenCV (3.4) via pip. Here is the code I am using :

    


    import numpy as np
import cv2

cap = cv2.VideoCapture('rtsp://192.168.15.116:554/onvif1')

while(cap.isOpened()):
    ret, frame = cap.read()

    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()


    


    I am getting the following error :

    


    [rtsp @ 03858a40] Nonmatching transport in server reply
warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:808)
warning: rtsp://192.168.15.116:554/onvif1 (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:809)


    


    I can go to cmd and type

    


    ffplay rtsp://192.168.15.116/onvif1


    


    and the video will run as well as in VLC using the same rtsp address. Using

    


    cv2.VideoCapture(0)


    


    also works with my webcam.

    


    I've tried copying the file "opencv_ffmpeg340.dll" into all path folders but to no avail. I've also checked build and all video I/O show up with "YES" except for Gstreamer. Any help would be appreciated.
Thank you.

  • ffmpeg osx error while writing file : "Unrecognized option 'preset'.Error splitting the argument list : Option not found

    22 décembre 2023, par asabbah

    I have the following simple Python Code :

    



    yellow_output = 'test_videos_output/solidYellowleft.mp4'
clip1 = VideoFileClip("test_videos/solidYellowLeft.mp4")
yellow_clip = clip1.fl_image(process_image)
yellow_clip.write_videofile(yellow_output, audio=False)


    



    The "process_image" function just returns what you give it (created for testing purposes).

    



    Running Python 3.5.4, ffmpeg 2.8.6, on OSX 10.11.6

    



    I get the error :

    



    OSError: [Errno 32] Broken pipe

MoviePy error: FFMPEG encountered the following error while writing file test_videos_output/solidWwhiteright.mp4:

 b"Unrecognized option 'preset'.\nError splitting the argument list: Option not found\n"


    



    the video file is not generated ; how to get rid of this error ; so I can generate the MP4 file ?

    



    Note : the same code runs happily on Ubuntu 16.04
