The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ffmpeg : Depends: libavdevice58 (= 7:4.2.7-0ubuntu0.1) but it is not going to be installed
          Depends: libavfilter7 (= 7:4.2.7-0ubuntu0.1)
          Depends: libavformat58 (= 7:4.2.7-0ubuntu0.1) but it is not going to be installed

  I solved it by install the reason of conflit library with a specific version, may be someone will need the solution.

  


  step 1. fix-broken

  step2. find the reason of unmet dependencies :

The following packages have unmet dependencies:
 libavformat58 : Depends: libchromaprint1 (>= 1.3.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


  


  Here the problem is from libchromaprint1

  


  step3. find candidate versions of libchromaprint1(conflict reason)

  


  # apt-cache policy libchromaprint1
libchromaprint1:
  Installed: (none)
  Candidate: 1.5.1-1~20.04.sav0
  Version table:

  step4. install the old version of libchromaprint1 to solve the conflicts

  


  # sudo apt install libchromaprint1=1.4.3-3build1

  step5. reinstall ffmpeg

  


  # sudo apt install ffmpeg

  Done. the reason of conflict is that the latest version of libraries have conflict, by install old version of the conflicted ones to solve it.

• ffprobe to bitrate variable stopped working

  6 novembre 2023, par Bricktop

  I have a simple script to encode a video using the same bitrate as the original. I use ffprobe to fetch the bitrate like this :

  


  ffprobe "%file%" -v 0 -select_streams v:0 -show_entries stream=bit_rate -print_format compact=p=0:nokey=1 >%temp%\bitrate.txt


  


  However, while fixing a but in the script where I had an odd number of " marks, I suddenly ran into this problem with ffprobe :

  


  Argument ' -v 0 -select_streams v:0 -show_entries stream=bit_rate -print_format compact=p=0:nokey=1 >C:\Users\ADMINI~1\AppData\Local\Temp\bitrate.txt' provided as input filename, but 'D:\VIDEO\AMBIANCE\SCOPITONE\MUSIC TELEVISION\This Here - Calm - OFFICIAL VIDEO (1080p 25fps AV1-128kbit AAC).mp4' was already specified.


  


  I am trying to understand this, scanning insanely for yet another " or something in my code but can't figure it out. Here is the full code :

  


  :: write file to queue (first)
move /y "%~dpn0.txt" "%temp%\%~n0.tmp" >nul
echo "%~1" >"%~dpn0.txt"
type "%temp%\%~n0.tmp" >>"%~dpn0.txt"

:: desyncronize instances (todo: try support for adding 9 files at a time)
timeout /t %time:~9,1% /nobreak
:: if not first instance exit
tasklist /fi "imagename eq handbrakecli.exe" | find /i "handbrakecli" && exit
title Transcode

:: delegate queue
for /f "delims=" %%f in (%~dpn0.txt) do (
    set "name=%%~nf"
    set "file=%%~f"
    rem todo: if file has x264 or other video codec mentioned, change to x265
    set "code=%%~dpnf (x265 transcoded)%%~xf"
    call :transcode
)
echo all done!
exit /b

:transcode
title "%name%"
if not exist "%file%" echo %date% %time% source file missing %file% >>%~dpn0.log & goto cleanup
if exist "%code%" echo %date% %time% target file exists %file% >>%~dpn0.log & goto cleanup

:: determine appropriate bitrate (does not seem to work on .webm files, closing the script as a result)
%~dp0ffprobe "%file%" -v 0 -select_streams v:0 -show_entries stream=bit_rate -print_format compact=p=0:nokey=1 >%temp%\bitrate.txt
set /p bitrate=<%temp%\bitrate.txt
:: reduce to full kilobytes
set "bitrate=%bitrate:~0,-3%"
if not defined bitrate echo failed to fetch bitrate & echo %date% %time% no bitrate for %file% >>%~dpn0.log & exit /b
if %bitrate% gtr 7000 set bitrate=7000

:: transcode
%~dp0HandBrakeCLI -i "%file%" -o "%code%" --encoder x265_10bit --encoder-preset slow --encoder-profile main444-10 --vb %bitrate% --two-pass --turbo --audio 1-9 --aencoder copy --audio-copy-mask aac,ac3,mp2,mp3,opus --audio-fallback opus --ab 160 --drc 2.0

:: remove current file from queue, regardless
:cleanup
findstr /v /c:"%file%" "%~dpn0.txt" >"%temp%\%~n0.tmp"
move /y "%temp%\%~n0.tmp" "%~dpn0.txt"


  


  It appears that the set "file=%%~f" is the problem, somehow it shows up as set "file=D:\VIDEO\this video here.mp4" " where the last two characters " should not belong, and I don't know what to change to fix this.

  


  Every type of improvement to the script is very welcomed !
