• 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.

• Scale with scale_vaapi and than pad, got error. Seems ok without "pad"

  24 mai 2023, par huangda1982

  My computer : customized Linux, haswell
I am trying to scale 1280x720 video to 640x450 in 640x480 frame with black borders. To do so, I run this command :

  


  ffmpeg -v warning -hide_banner -init_hw_device vaapi=vaapi0:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device vaapi0 -filter_hw_device vaapi0 -i 'my_video.mp4' -vf 'scale_vaapi=640:450,pad=640:480:0:14' -c:v h264_vaapi -q:v 18 -profile:v main -level 3.1 -c:a aac -q:a 3 -f mp4 out.mp4 -loglevel verbose


  


  And I got this error :

  


  Impossible to convert between the formats supported by the filter &#x27;Parsed_scale_vaapi_0&#x27; and the filter &#x27;auto_scaler_0&#x27;<br />&#xA;Error reinitializing filters!&#xA;Failed to inject frame into filter network: Function not implemented&#xA;Error while processing the decoded data for stream #0:0&#xA;

  


  When I removed the ",pad=640:480:0:14" part, the command continued. I pressed ctrl-c, and did not check the result.

  


  "-q:v 18", "-level 3.1" and "-q:a" options seem not work.

• 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
