• Which library supports showing a secure RTSP stream on Windows ?

  26 octobre 2022, par Juergen

  I have a windows application that consumes streams from IP-Cameras.
Currently I am using WebEye, an open-source component that uses ffmpeg under the hood.
I now want to connect to an AXIS IP-Camera which supports RTSPS (RTSP over SSL/TLS).
Since WebEye doesn't support RTSPS directly I was hoping that I could get ffmpeg to do the job and adjust WebEye.
Alternatively I would use any other Streaming-Library that supports viewing a secure RTSPS-stream on Windows, but I didn't come across any.

  


  So, I guess my questions are :

  


  

  1. Are there any Windows-Tools that supports RTSPS-Streams

  


  2. Are there any libraries that I can use in my Windows-application to show the RTSPS-stream ?

  


  3. Can I get ffmpeg and/or ffplay to play the RTSPS-Stream ?

  


  


  Thanks in advance for the help !

  


  Best Regards

  So, I guess my questions are :

  


  

  1. Are there any Windows-Tools that supports RTSPS-Streams that I can use for reference/testing ?

  


  2. Are there any libraries that I can use in my Windows-application to show the RTSPS-stream ?

  


  3. Can I get ffmpeg and/or ffplay to play the RTSPS-Stream ?

• Why does OpenCV read video faster than FFMPEG ?

  17 septembre 2022, par tadejsv

  I noticed that OpenCV reads video frames almost 2x faster than FFMPEG.

  


  Why is that ? I thought all OpenCV does is call FFMPEG under the hood, possibly adding its own overhead.

  


  Here's the code I use to obtain these results

  


  import cv2
import time
import numpy as np

cap = cv2.VideoCapture("BigBuckBunny.mp4", apiPreference=cv2.CAP_FFMPEG)
frames = int(cap.get(cv2.CAP_PROP_FRAME_COUNT))

start = time.perf_counter()
while True:
    ret, frame = cap.read()
    if ret is False:
        break
    assert frame.shape == (720, 1280, 3)
    assert frame.dtype == np.uint8
end = time.perf_counter()

print(f"{frames/(end-start):.1f} frames per second")
# Output: 692.3 frames per second

cap.release()


  


  For FFMPEG (using the python-ffmpeg library :

  


  import ffmpeg
import numpy as np
import time

vid_info = ffmpeg.probe("BigBuckBunny.mp4")['streams'][1]
frames = int(vid_info['nb_frames'])

process1 = (
    ffmpeg
    .input("BigBuckBunny.mp4")
    .output('pipe:', format='rawvideo', pix_fmt='bgr24')
)
print(process1.compile())
# Output: ['ffmpeg', '-i', 'BigBuckBunny.mp4', '-f', 'rawvideo', '-pix_fmt', 'bgr24', 'pipe:']


process1 = process1.run_async(pipe_stdout=True)

start = time.perf_counter()
while True:
    in_bytes = process1.stdout.read(1280 * 720 * 3)
    if not in_bytes:
        break
    frame = np.frombuffer(in_bytes, np.uint8).reshape([720, 1280, 3])
end = time.perf_counter()
print(f"{frames/(end-start):.1f} frames per second")
# Output: 373.6 frames per second
process1.wait()


  


  Here's information about the video ( 10 minutes length)
