• How to keep video quality same as it is after merge intro image beggining to video using ffmpeg

  13 juin 2021, par Manoj Kag

  I have selected high resolution video but once i run command the video resolution quality was changed and too poor quality's video i get as output video, but i don't would like to loose my video quality. let me share full command and complete log below :

  


  Note : libx264 encoder is not supporting iOS, I'm getting failure error so i use h264_videotoolbox so i would like to get supported command with h264_videotoolbox encoder

  


  Command :

  


  


  ffmpeg -i test.MOV -loop 1 -t 5 -i 2.jpg -f lavfi -t 5 -i anullsrc
-filter_complex "[0:v]trim=0:5,drawbox=t=fill[base] ;[1][base]scale2ref=iw:ih:force_original_aspect_ratio=decrease:flags=spline[2nd][base2] ;[base2][2nd]overlay='(W-w)/2' :'(H-h)/2'[padded] ;[padded][2:a][0:v][0:a]concat=n=2:v=1:a=1[v][a]"
-c:v h264_videotoolbox -c:a aac -map "[v]" -map "[a]" output.mp4

• subprocess call of ffmpeg returns negative value

  11 juin 2019, par Zak44

  Here is the original command line call that works at shell :

  ffmpeg -i /Users/abc/Desktop/Test/Full_Mov.mov -vf "drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf: text='SCENE BLAH BLAH - %{frame_num}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: fontsize=20: box=1: boxcolor=black: boxborderw=5","format=yuv420p" -f segment -segment_frames 123 -reset_timestamps 1 -c:a copy -map 0 "/Users/abc/Desktop/Test/%03d_test40.mov"

  Getting a negative value when trying to run ffmpeg via subprocess, causing it to fail and not process. I’ve even tried dumbing down the call to just run ffmpeg by itself with no arguments, and it still returns a negative value.

  import subprocess
  
  ffmpeg = "/usr/local/bin/ffmpeg"
  
  source = "/Users/abc/Desktop/Test/Full_Mov.mov"
  
  destination = "/Users/abc/Desktop/Test/%03d_test40.mov"
  
  cmd = "%s -i %s -vf \"drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf: text='SCENE BLAH BLAH - %%{frame_num}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=5\",\"format=yuv420p\" -f segment -segment_frames 123 -reset_timestamps 1 -c:a copy -map 0 \"%s\"" % (ffmpeg, source, destination)
  
  log("ffmpeg cmd: %s" % cmd)
  
  log(subprocess.check_output(cmd, shell=True))

  When running full command :

  CalledProcessError: Command '/usr/local/bin/ffmpeg -i /Users/abc/Desktop/Full_Mov.mov -vf "drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf: text='SCENE BLAH BLAH - %{frame_num}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=5","format=yuv420p" -f segment -segment_frames 318 -reset_timestamps 1 -c:a copy -map 0 "/Users/abc/Desktop/Test/%03d.tmp.mov"' returned non-zero exit status -8
  
      raise CalledProcessError(retcode, cmd, output=output)

  When running just ffmpeg no arguments :

  CalledProcessError: Command '/usr/local/bin/ffmpeg' returned non-zero exit status 1
  
      raise CalledProcessError(retcode, cmd, output=output)

  Latest output with suggested changes below :

• configure : Improve the check for the rsync —contimeout option

  configure : Improve the check for the rsync —contimeout option
  Traditionally, macOS has shipped an old version of rsync that lacked
  
  support for this option, hence this check (added in
  
  a8b3f0c5cf548f654e30c981988bb71981a3f8d3).
  However, in macOS 15.x, Apple have switched to providing rsync as a
  
  different tool, openrsync. The version of openrsync in at least
  
  macOS 15.2 does include "[—contimeout]" (note the lack of "=" after
  
  the option), in the output of "rsync —help", but when used, the tool
  
  errors out with "rsync : —contimeout=60 : unknown option". So apparently
  
  the tool erroenously lists the option as supported, while it really
  
  isn't.
  The original rsync tool (with a new enough version) prints
  
  "—contimeout=SECONDS" in the output of "rsync —help".
  It is unclear which version of openrsync Apple are shipping ; the latest
  
  upstream openrsync from OpenBSD does support the option and includes
  
  "[—contimeout=seconds]" in the output of "—help", and older versions
  
  don't seem to include the option as listed at all.
  Therefore, check for "—conntimeout=" with the "=", this should
  
  properly detect both new enough rsync and openrsync.
  This fixes running "fate-rsync" on macOS 15.x.
