• DNN OpenCV Python using RSTP always crash after few minutes

  1er juillet 2022, par renaldyks

  Description :

  


  I want to create a people counter using DNN. The model I'm using is MobileNetSSD. The camera I use is IPCam from Hikvision. Python communicates with IPCam using the RSTP protocol.

  


  The program that I made is good and there are no bugs, when running the sample video the program does its job well. But when I replaced it with IPcam there was an unknown error.

  


  Error :

  


  Sometimes the error is :

  


  [h264 @ 000001949f7adfc0] error while decoding MB 13 4, bytestream -6
[h264 @ 000001949f825ac0] left block unavailable for requested intra4x4 mode -1
[h264 @ 000001949f825ac0] error while decoding MB 0 17, bytestream 762


  


  Sometimes the error does not appear and the program is killed.

  Update Error

  


  After revising the code, I caught the error. The error found is

  


  [h264 @ 0000019289b3fa80] error while decoding MB 4 5, bytestream -25


  


  Now I don't know what to do, because the error is not in Google.

  Old Code

  


  This is my very earliest code before getting suggestions from the comments field.

  New Code

  


  I have revised my code and the program still stops taking frames. I just revised the PersonDetection_UsingMobileNetSSD() function. I've also removed the multithreading I was using. The code has been running for about 30 minutes but after a broken frame, the code will never re-execute the program block if ret == True.

• Can open RTSP camera stream in FFMPEG but not in Gstreamer rtspsrc : Bad Request (400)

  6 août 2022, par Joran Apixa

  I have a Panasonic WV-SW559 camera set up as an RTSP stream.

  


  VLC can perfectly open the RTSP stream and display it, as well as FFMPEG.
However, when I try to set up a simple gstreamer pipeline, it does not want to open.
I execute the following command :

  


  gst-launch-1.0 rtspsrc --gst-debug=rtspsrc:5 location="rtspt://admin:12345@192.168.2.148:554/MediaInput/h264/stream_1" ! fakesink


  


  after which I get the following output :

  Does anyone have an idea on why this could occur ?

  


• FFmpeg saturates memory + CPU usage drops to 0% during very basic conversion of PNG files to MP4 video

  7 août 2022, par mattze_frisch

  I have this Python function that runs ffmpeg with minimal options from the Windows command line :

  


  def run_ffmpeg(frames_path, ffmpeg_path=notebook_directory):
    '''
    This function runs ffmpeg.exe to convert PNG image files into a MP4 video.
    
    Parameters
    ----------
    frames_path : string
        Absolute path to the PNG files
    ffmpeg_path : string
        Absolute path to the FFmpeg executable (ffmpeg.exe)
    '''
    
    from subprocess import check_call
    
    
    check_call(
        [
            os.path.join(ffmpeg_path, 'ffmpeg'),
            '-y',    # Overwrite output files without asking
            '-report',    # Write logfile to current working directory
            '-framerate', '60',    # Input frame rate
            '-i', os.path.join(frames_path, 'frame%05d.png'),    # Path to input frames
            os.path.join(frames_path, 'video.mp4')    # Path to store output video
        ]
    )


  


  When running it from a Jupyter notebook over 2500 PNG files (RGBA, ca. 600-700 kB each, 9000 x 13934 pixels), CPU usage briefly peaks to 100% before dropping to 0%, while memory usage quickly saturates to 100% and stays there, slowing the system down almost to a freeze, so I need to terminate ffmpeg from the task manager :

  The generated video file has a size of only 48 bytes and contains just a black frame when viewed in the VLC player.

  


  This is the ffmpeg log output :

  What is the problem ?

  


  By the way, the color model of the image files was confirmed by doing

  


  from PIL import Image


img = Image.open('C:\\Users\\EPI-SMLM\\Desktop\\e\\frame00000.png')
img.mode
-------------------------------------------------------------------
C:\Program Files\Python38\lib\site-packages\PIL\Image.py:3035: DecompressionBombWarning: Image size (125406000 pixels) exceeds limit of 89478485 pixels, could be decompression bomb DOS attack.
  warnings.warn(

'RGBA'


  


  The "decompression bomb warning" appears to be a false alarm/bug.

  


  UPDATE : I can confirm that this happens even when there are only 50 image files, i.e. 50 x 700 kB = 35 MB in total size. ffmpeg still gobbles up all available memory (almost 60 GB of private bytes !!!).

  


  And it also happens if ffmpeg is run from the command line.

  


  This must be a bug !
