• Keep trying a command until it returns "True" and then execute another

  6 janvier 2023, par Tyrone Hirt

  I'm trying to make a script to check the processor usage for a specific process every 10 seconds, and when the usage is less than 2% I want another 2 commands to be executed.

  


  The purpose is to know when the program has finished processing the requests, in order to release the execution of the other commands.

  


  I created this script to check the processor usage by this application :

  


  SET ProcessorUsage = wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:RenderQuery

%ProcessorUsage%


  


  And these are the commands I want to be executed when the processor usage of the RenderQuery application is less than 2% :

  


  for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy"

for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i"


  


  I tried to create a script that way here :

  


  SET ProcessorUsage = wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:RenderQuery
:Loop
IF %ProcessorUsage% LSS 2 (
(for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy") && (for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i")
) ELSE (
sleep 10 && goto Loop
)


  


  I also tried this way here :

  


  SET ProcessorUsage = wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:RenderQuery

:Loop
for %ProcessorUsage% LSS 2 do (
(for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy") && (for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i") || (sleep 10 && goto Loop)
)


  


  With these scripts I tried to create the window that only blinks and closes right away...

  


  What's the best way to do this ?

  


  EDIT

  


  Explaining in more detail : I work with video production, so I constantly need to render Proxy files, which are video files with low quality to be used during my video editing and replaced at the end of editing, this makes the much smoother video editing.

  


  Having said that, I have a folder model, inside this folder model there is a folder where I always download the video files from the camera and in that folder there is always a .bat file that opens all the video files in the software that generates proxy files of the camera's video files.

  


  This .bat file has this exact code :

  


  start "" "C:\Users\User\Downloads\FFmpeg_Batch_AV_Converter_Portable_2.8.4_x64\FFBatch.exe" -f "%~dp0\"


  


  When this software opens, it automatically renders the proxy files and their output is always in a child folder of the original files folder, and the name of the folder is Proxy.

  


  The issue is that I don't want them to be in several separate Proxy folders, so I created another .bat file that is in the parent folder of all video files, this script contains exactly these lines :

  


  for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy"

for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i"


  


  That is, it only searches recursively for files that are inside folders named Proxy, then it moves these files to the folder 03. Proxy that is inside the parent folder.

  


  The second line looks for all proxy folders (which are now empty) and deletes them.

  


  The point is : I currently run the second script manually, as soon as the render finishes, and I would like it to run automatically.

  


  Given this, I thought of adding a line in the first script, which opens the video files in the rendering program, this line would call the second script in the background, and the second script would be analyzing the CPU usage of this application every 10 seconds, and when the usage is less than 2% (in theory there is nothing else rendering, since it has a low CPU usage) it executes the lines that move the files and remove the folders.

  


  I think there's a good change for this to work, because this software renders 4 videos at a time, and this means that there is no time between stopping rendering a video and starting another... the CPU usage is always very high until all the videos are finished, so I think this would be the best signal to release the other commands.

  


• Why is "ffmpeg : command not found" in heroku, even with proper buildpack/config ?

  14 novembre 2022, par Jim

  In a node.js app hosted on heroku, ffmpeg is used by spawning processes, but is throwing errors anytime an ffmpeg command runs

  


  the error ffmpeg: command not found is thrown both in cli test heroku run ffmpeg as well as production logs

  


  Ive considered :

  


  

  • buildpack order

  


  • buildpack clearing/re-adding/redeploying

  


  • buildpack required env vars

  


  • heroku-stack-20 conflicts with buildpack#1 somehow ?

  


  


  Buildpack order :

  


  

  1. https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git

  


  2. https://github.com/heroku/heroku-buildpack-awscli.git

  


  3. https://github.com/timanovsky/subdir-heroku-buildpack.git

  


  4. heroku/nodejs

  


  


  Buildpack configs - from watching build logs, even though i havent set ffmpeg path, a default is found.

  


  beginning build logs (completes successfully, runs successfully - minus ffmpeg) :

  Any suggestions to further debug this ?

  


• OCI runtime exec failed : exec failed : (...) executable file not found in $PATH" : unknown

  12 octobre 2024, par Uğur Kaya

  I have dockerized an app which has ffmpeg installed in it via libav-tools. The app launches without problem, yet the problem occured when fluent-ffmpeg npm module tried to execute ffmpeg command, which was not found. When I wanted to check the version of the ffmpeg and the linux distro set up in the image, I used sudo docker exec -it c44f29d30753 "lsb_release -a" command, but it gave the following error : OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"lsb_release -a\": executable file not found in $PATH": unknown

  



  Then I realized that it gives me the same error with all the commands that I try to run inside the image or the container.

  



  OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"ffmpeg -a\": executable file not found in $PATH": unknown


  



  This is my Dockerfile :

  



  FROM ubuntu:xenial
FROM node
RUN apt-get -y update
RUN apt-get --yes install libav-tools
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install
COPY . /usr/src/app
RUN npm run build
ENV NODE_ENV production
EXPOSE 8000
CMD ["npm", "run", "start:prod"]


  



  I would kindly ask for your help. Thank you very much !
