Following the post: https://stackoverflow.com/a/34489424/14947713 where @dbenham posted his code:
Where he is able to Redirect Stdout/Stderr to variables and designs an early version that utilizes a file which is more efficient as he claims.
What I am not able to figure out is how to replace his "yourCommand" with a :call to a piece of code lower in the same script (ffmpeg processes & For loops). In the end I am trying to control what appears on the console but to thoroughly record what happens in a log file.
I've been searching and comparing/testing scripts for days but can't seem to break through this.
The bottom piece of code is the ffmpeg script with it's existing logging function which I am aiming to recreate/reutilize within this @dbenham script.
@echo off
setlocal disableDelayedExpansion
set "STDOUT="
SET "STDERR="
for /f "delims=" %%E in (
'2^>^&1 (for /f "delims=" %%O in ('^
yourCommand^
^^^^^^^| findstr /n /r "^"'^) do @(echo ^^^^^^^|%%O^)^) ^| findstr /n /r "^"'
) do (
set "ln=%%E"
setlocal enableDelayedExpansion
set "ln=x!ln:*:=!"
set "ln=!ln:=s!"
if "!ln:~0,2!"=="x|" (
set "ln=!ln:~0,-1!"
for /f "delims=" %%A in (^""!STDOUT!"^") do for /f "delims=" %%B in (^""!ln:*:=!"^") do (
endlocal
set "STDOUT=%%~A%%~B
"
)
) else (
for /f "delims=" %%A in (^""!STDERR!"^") do for /f "delims=" %%B in (^""!ln:~1!"^") do (
endlocal
set "STDERR=%%~A%%~B
"
)
)
)
setlocal enableDelayedExpansion
for %%L in (^"^
%= empty line =%
^") do (
if defined STDOUT (
set "STDOUT=!STDOUT:
=%%~L!"
set "STDOUT=!STDOUT:s=!"
set "STDOUT=!STDOUT:~0,-1!"
)
if defined stderr (
set "STDERR=!STDERR:
=%%~L!"
set "STDERR=!STDERR:s=!"
set "STDERR=!STDERR:~0,-1!"
)
)
echo ** STDOUT **
echo(!STDOUT!
echo ** STDERR **
echo(!STDERR!
exit /b
I have modified the above code as such for easier testing purposes:
@echo off
setlocal disableDelayedExpansion
set /a out.cnt=err.cnt=0
(for /f "delims=. tokens=1*" %%A in ('^""%~f0" :test5 2^>err.log ^| findstr /n "^"^"') do (
for /f "delims=:" %%N in ("%%A") do (
set "ln=%%A"
echo this is the ln var: "%ln%"
setlocal enableDelayedExpansion
for /f "delims=" %%B in (^""!ln:*:=!"^") do (
endlocal
set "out.%%N=%%~B"
set "out.cnt=%%N"
)
)
)
)2>err.log
for /f "delims=" %%A in ('findstr /n "^" err.log') do for /f "delims=:" %%N in ("%%A") do (
set "ln=%%A"
echo this is the ln2 var: "%ln%"
setlocal enableDelayedExpansion
for /f "delims=" %%B in (^""!ln:*:=!"^") do (
endlocal
set "err.%%N=%%~B"
set "err.cnt=%%N"
)
)
:: Display the results
setlocal enableDelayedExpansion
echo ** STDOUT **
for /l %%N in (1 1 %out.cnt%) do echo(!out.%%N!
echo ** STDERR **
for /l %%N in (1 1 %err.cnt%) do echo(!err.%%N!
echo ** STDERR END **
exit /b

I came across this script(below here): https://stackoverflow.com/a/9344547/14947713 but it is beyond-me for the moment on how I can re-configure to use.

The existing ffmpeg script with it's existing logging which
1st: Sets up the logging structure to the %drive% destination (contains "!"), creates the new logging destination directory(s) and saves the filename as the date+time.
2nd(core-1): Uses ffprobe.exe to search for define audio codecs (i.e. "dts")
3rd(core-2): Each result is then fed to ffmpeg to copy the file but to transcode to "eac3" & "ac3".
Disclosure:
Existing Problems with this ffmpeg script include the "FilesEncoded" count.
Ideally it would show the count
I am also trying to incorporate "start /abovenormal" so I can have the ffmpeg processes a high priority.
I seem to be stuck, but I have spent yesterday looking to use ffmpeg-progressbar-cli https://github.com/sidneys/ffmpeg-progressbar-cli so it would show a per-file progress bar, and basic information, which is why there is a 2nd FINALCOMMAND line ::out at the end. But no luck....
I appreciate any help anyone can provide.
