• 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.

  


• How ffmpeg work on server for different type of users ? [on hold]

  7 août 2016, par sam

  I have a question about ffmpeg and I am using mac and xampp and php and jQuery. I make a function that upload video or image file or another type when I saw examples of ffmpeg in Stack Overflow. My questions are :

  1. client can be window user or mac or another than we have to download all different type of ffmpeg file for example ffmpeg.exe and mac can be another because when I saw how to download ffmpeg than they show me different operating system.

  2. And where we have to save ffmpeg file in xampp

  3. If I download all things for mac and I run it and it works and I make my website online and than any Windows user or Linux user will upload video it will work for him also. But we do not client download ffmpeg in their system

  If anybody know good example of create thumbnail for video please tell me.

• ffmpeg frame type inside name of output

  29 juillet 2017, par Adminy

  With this command I can split video to individual h265 frames.

  ffmpeg -i input.h265 -c:v libx265 -f image2 output/%d.h265

  How can I make "output name" to contain frame "type" ?

  Like %d_%frame_type.h265
