OpenCV cannot read AVI/MP4 file. [mpeg4 @ 0x55935a6280c0] get_buffer() failed
6 décembre 2023, par Alex MurphyI am trying to read single frames from an mp4 file using open-cv in Python


video_path = 'test.mp4'
cam = cv2.VideoCapture(video_path, cv2.CAP_FFMPEG)

success,image = cam.read()
count = 0
while success:
 success,image = cam.read()
 print('Read a new frame: ', success)
 count += 1



The success boolean instantly evaluates to false when trying to read the first frame. These are the errors I'm getting :


[mpeg4 @ 0x55935a6280c0] get_buffer() failed
[mpeg4 @ 0x55935a6280c0] thread_get_buffer() failed
[mpeg4 @ 0x55935a6280c0] get_buffer() failed (-12 (nil))
[mpeg4 @ 0x55935a52bd80] Too many errors when draining, this is a bug. Stop draining and force EOF.



I can convert files from mp4 to avi and avi to mp4 using ffmpeg in my terminal. It also shows no signs of the files being corrupted. The code still doesn't work when trying to read an mp4. I have 20GB of RAM so I don't think it is a RAM problem.


Python 3.6.13, opencv-python 3.4.18.65. Using Linux


Edit : Restarting machine and changing from 20GB RAM to 40GB sometimes fixes it. Considering its a 17 second file only a few MB big this doesn't seem to make sense ?
