• fftools/cmdutils : fix error message for "ffmpeg -init_hw_device list"

  26 mars, par Jun Zhao

  fftools/cmdutils : fix error message for "ffmpeg -init_hw_device list"
  When running 'ffmpeg -init_hw_device list' to display available hardware
  
  devices, it incorrectly shows an error message :
  
  "Failed to set value 'list' for option 'init_hw_device' : Immediate exit requested"
  This is a regression introduced by commit a50f90f1c23. The command is
  
  actually working as intended - it should exit after listing devices, but
  
  shouldn't display an error message.

• FFmpeg - invalid argument on a creation of MP4 with .SRT - "Unable to parse option value "Link_to_the.srt" as image size...?

  20 mai 2023, par sKunZel

  I'm stuck for 2 weeks on same problem on developping a command that bring together a .mp4 file consisting on a fixed image & audio from a .mp3 and then burnt-in subtitle from a stylized .srt into a new MP4.

  


  Here is my command :
 command = f"""ffmpeg -report -i "input_video_arg_abs" -vf "subtitles='input_srt_arg_abs':original_size=816x1456:force_style='FontName=Open Sans Italic,FontSize=13,MarginR=10,MarginV=149'" -c:v libx264 -crf 18 -c:a copy -movflags +faststart "output_video" """

  


  And you can see here the main script definitions of variables and call to fonction :

  


  


  input_srt = os.path.normpath(os.path.join(input_directory, srt_file))
print(f"Chemin du fichier SRT : input_srt")
reformat_srt(input_srt)
final_video_output=os.path.normpath(os.path.join(output_directory,
os.path.splitext(mp3_file)[0] + '.mp4'))
time.sleep(0.5)
create_final_video(temp_video_output, input_srt, final_video_output)

  


  


  This code generated an output file correctly named but 0 Ko. Every log i found indicated an error in the way of my .srt but when i print my input_srt it is correct.

  


  Here i add up some logs :

  I'm thinking of "E :" as the problem since on Windows it should be correct but with FFMPEG langage, i don't know...

  


  I wish anyone can help me, and will be glad if it is a tricky solution. Else, sorry for my newbism...
Thanks
