• Flutter_ffmpeg : At least one output file must be specified

  22 mars 2020, par Jehonadab Okpukoro

  I’m trying to crop a video with Flutter_ffmpeg package using this -i $inputPath -filter:v "crop=80:60:200:100" -c $outputPath, but I’m having this error message

  Running FFmpeg with arguments: [-i, /data/user/0/com.timz/app_flutter/Movies/flutter_test/1584827688309.mp4, -filter:v, crop=80:60:200:100, -c, /data/user/0/com.timz/cache/output.mp4].

• FFmpeg psycho-visual options - psy-rdoq

  7 avril 2020, par SLVR

  I'm new to encoding and I like to do my encodings in x265 10bit. Currently, I'm facing a little issue with ffmpeg. I noticed when I'm using libx265 encoder output file looks a little bit blurred or small detail loss. Code I used to do my encodes is

  



  ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -c:a copy -y output-x26510bit.mkv


  



  I've found out psycho-visual options might help in this case. I modified my code in to

  



  ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq 4 --rdoq-level 1 -c:a copy -y output-x26510bit.mkv


  



  When I issue the above command, I get an error code
