Convert simple Bash script to PowerShell ?
10 février 2015, par vulcan ravenI have pulled the Bash script from here, which checks the AVI file for bad frames using ffmpeg and cygwin extension. I am able to execute the code in Mingw. I put ffmpeg.exe (ren ffmpeg), cygwin1.dll & cygz.dll in Mingw’s bin dir (/c/mingw/bin/). Now, I am looking to port this bash code to PowerShell. Can anyone shed some PowerShell light on this one ?
Script : (path : /c/mygw/bin/AviConvert)
#!/bin/bash
FFMPEG="ffmpeg"
LIST=`find | grep \.avi$`
for i in $LIST; do
OUTP="$i.txt"
OUTP_OK="$i.txt.ok"
TMP_OUTP="$i.tmp"
if [ -f "$OUTP" -o -f "$OUTP_OK" ] ; then
echo Skipping "$i"
else
echo Checking "$i"...
RESULT="bad"
ffmpeg -v 5 -i "$i" -f null - 2> "$TMP_OUTP" && \
mv "$TMP_OUTP" "$OUTP" && \
RESULT=`grep -v "\(frame\)\|\(Press\)" "$OUTP" | grep "\["`
if [ -z "$RESULT" ] ; then
mv "$OUTP" "$OUTP_OK"

Raspberry Pi Camera feedback freezes when moving NEMA 17 stepper motor with A4988 stepper motor driver [closed]
31 août 2023, par Broteen DasI 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 ?
