  • Slow execution of cuCtxDestroy causing Windows desktop freeze [closed]

    24 avril 2024, par sun

    I’m encountering a problem with the cuCtxDestroy function that seems to be causing my system to freeze and result in a black screen. I’m running Windows 11 on my computer, and I would appreciate any assistance in troubleshooting this issue.

    


    When I call cuCtxDestroy, it takes more than 10 seconds to complete, during which both the GPU and CPU appear to be stuck. Eventually, the screen goes black, and in some cases, the system may recover, while in other cases, it requires a system reboot.

    


    Here is some information about my system :

    


      


    • Integrated Intel graphics card

      


      • 


    • NVIDIA GeForce GTX 1650

  • Passing commands with double quotes to subprocess.call in python

    7 juin 2018, par Georgе Stoyanov

    I want to pass a command to a Linux machine running ffmpeg using python containing a double quotes. That’s my script :

    drawtext = "drawtext=\"fontfile=DejaVuSans: text='Random Name': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=20: y=20\""
    
subprocess.call(["ffmpeg", "-v", "error", "-i", input.mp4, "-vf", drawtext, output.mp4])

    If I print the drawtext variable this is the output :

    drawtext="fontfile=DejaVuSans: text='Reference Image': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=20: y=20"

    And this is my error in ffmpeg :

    [Parsed_drawtext_0 @ 0x564ad79f99c0] [Eval @ 0x7ffd41131810] Invalid chars '"' at the end of expression '20"'
    
[Parsed_drawtext_0 @ 0x564ad79f99c0] Failed to configure input pad on Parsed_drawtext_0
    
Error reinitializing filters!
    
Failed to inject frame into filter network: Invalid argument
    
Error while processing the decoded data for stream #0:0

    If I execute the following command in Linux shell it works just fine :

    $ ffmpeg -ss 10 -i input.mp4 -vf drawtext="fontfile=DejaVuSans: text='Random Name': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=20: y=20" output.mp4

  • ffmpeg taking so much time to extract frames from mpeg-ts file

    19 septembre 2016, par Syed Azaruddin

    I got a problem from one mpeg-ts video. Actually it was created by some one else and even I don’t know how they are created. The problem is that, ffmpeg is taking so much time to decode all frames from the mpeg-ts video. The command I used for this operation is...

    ffmpeg -i shame-run.mov -r 24/1 test/output%d.jpg

    Actually my application is integrated with ffmpeg v2.1.1. and I had a code for detecting black frames in a mpeg-ts video. Here, my code is not able to detect all black frames from ffmpeg for this mpeg-ts video. So, I taken standalone ffmpeg of same version as mentioned above and decoded standalone. But, it is taking so much time i.e., it is taken half an hour for decoding 1 min duration video.

    So, is there any reason is that ffmpeg not able to extract as fast as required, and is there any reason that video got some errors.
