• Revert "lavc/nvenc : handle frame durations and AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE"

  Revert "lavc/nvenc : handle frame durations and AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE"
  The implementation is flawed in that the frame opaque data is not in
  
  fact correctly reordered along with the packets, but is being output in
  
  packet input order, just like the dts are.
  This reverts commit 35538097038fd1e36577306d3165f38c8fa02466.

  lavc/qsvenc : avoid data copy if possible
  The data copy is unnecessary for packed formats when frame width and
  
  height are aligned
  For example :
  
  $ ffmpeg -f lavfi -i testsrc=size=1920x1088 -vf "format=yuyv422" -c:v hevc_qsv -f null -

• 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
