  • Raspberry Pi Camera feedback freezes when moving NEMA 17 stepper motor with A4988 stepper motor driver [closed]

    31 août 2023, par Broteen Das

    I have a Raspberry Pi with a camera module and a NEMA 17 stepper motor connected to it. When I run the command ffplay /dev/video0, the video runs perfectly. However, whilst the video is running, and I run a script that moves the Stepper motor with the A4988 stepper motor driver, the video feed freezes and needs to be restarted.

    


    At first I thought it was ffmpeg's fault, so I tried viewing the feed with OpenCV, but the same probelem persisted.

    


    I also thought that the CPU prioritization was causing the problem, but this one time, the entire Raspberry Pi froze. The Keyboard, mouse, keys, numlock key, everything was dead (the Numlock light on my keyboard was on, I tried toggling the NumLock, but it did not go off) and so I had to turn off and turn on again the power supply to reboot the Pi.

    


    How do I get rid of this issue ?

  • How to seal subtitle on the video permanently ? ffmpeg

    10 octobre 2017, par Robert Choy

    I am able to add subtitle to my mp4 ; however, when i upload it on youtube, the subtitle is gone, disappeared.

    So i am asking if there is any method to make the subtitle on the video (forever, permanently, seal it, burn it, force everyone watch the video with subtitle, can’t even turn it off manually)

    ffmpeg -i video.mp4 -i subtitle.srt -c copy -c:s mov_text -disposition:s:0 forced \
    
permanently-subtitle-video-please.mp4

    i dont like the design of youtube subtitle, so i would love to upload my video + subtitle as one thing.

    sorry i a not an English native speaker, hope you understand what i am trying to ask. thanks
