• ffmpeg conversion .dav to any video files

  2 février 2021, par Marcello Galvão

  I am trying for days to convert .dav file (file generated by dvrs [image recorders]). I have tried several variations with ffmpeg and can not succeed.

  



  Command and console output :

  



  $ ffmpeg -i input.dav -codec:v libx264 -crf 23 -preset medium -codec:a libfdk_aac -vbr 4 -movflags faststart -vf scale=-1:720,format=yuv420p output.mp4

Codec AVOption vbr (VBR mode (1-5)) specified for output file #0 (output.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

• FFmpeg fontcolor_expr to dynamically change fontcolor over time

  26 juin 2017, par Matthew

  I’m using Fluent-FFmpeg with Node.JS to create videos with text overlaid on them and I’m wanting to change the color of the text as the video progresses.

  My filters follow this pattern :

  drawtext=enable='between(t,18.93,20.28)':fontfile=fonts/cousine-bold.ttf:fontsize=144:fontcolor_expr=%{expr\\\: if(between(t\\, 0\\, 20)\\, 888888\\, 111111)}:x=82:y=288:text='PROGRAMMING'

  And it prints out this stuff :

  There aren’t a lot of examples of fontcolor_expr, so I wanted to see if anyone had experience with this. Any tips on changing fonrcolors dynamically without creating multiple filters ?

  Please note that fontcolor_expr=white and fontcolor_expr=888888 are valid and create videos with a fixed font color.

• ffmpeg got stuck while trying to crossfade merge two videos

  30 juin 2017, par Jeflopo

  I’m trying to do a crossfade merge (1s) between two videos. An intro (39secs duration) video with the main video. When I executed the command it started working without throwing errors but at some frame ffmpeg gets stuck.

  I read a lot of q/a here in stackoverflow, and the official docs but I can’t solve this so :

  This is the command :

  ffmpeg -i "inputs/intro.mp4" -i "inputs/240p.mp4" -an -filter_complex \
  
      "[0:v]trim=start=0:end=38,setpts=PTS-STARTPTS[firstclip]; \
  
      [0:v]trim=start=38:end=39,setpts=PTS-STARTPTS[fadeoutsrc]; \
  
      [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip]; \
  
      [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc]; \
  
      [fadeinsrc]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[fadein]; \
  
      [fadeoutsrc]format=pix_fmts=yuva420p, fade=t=out:st=0:d=1:alpha=1[fadeout]; \
  
      [fadein]fifo[fadeinfifo]; \
  
      [fadeout]fifo[fadeoutfifo]; \
  
      [fadeoutfifo][fadeinfifo]overlay[crossfade]; \
  
      [firstclip][crossfade][secondclip]concat=n=3[output]; \
  
      [0:a][1:a] acrossfade=d=1 [audio]" -vcodec libx264 -map "[output]" -map "[audio]" "outputs/240p.mp4"

  Here’s the raw command (the exact command I used) :

  ffmpeg -i "inputs/intro.mp4" -i "inputs/240p.mp4" -an -filter_complex "[0:v]trim=start=0:end=38,setpts=PTS-STARTPTS[firstclip]; [0:v]trim=start=38:end=39,setpts=PTS-STARTPTS[fadeoutsrc]; [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip]; [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc]; [fadeinsrc]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[fadein]; [fadeoutsrc]format=pix_fmts=yuva420p, fade=t=out:st=0:d=1:alpha=1[fadeout]; [fadein]fifo[fadeinfifo]; [fadeout]fifo[fadeoutfifo]; [fadeoutfifo][fadeinfifo]overlay[crossfade]; [firstclip][crossfade][secondclip]concat=n=3[output]; [0:a][1:a] acrossfade=d=1 [audio]" -vcodec libx264 -map "[output]" -map "[audio]" "outputs/240p.mp4"

  The "error" is reproducible with and without the -an and the acrossfade filters.

  This is the output :

  PS C:\scripts\ffmpeg> ffmpeg -i "inputs/intro.mp4" -i "inputs/240p.mp4" -an -filter_complex "[0:v]trim=start=0:end=38,setpts=PTS-STARTPTS[firstclip]; [0:v]trim=start=38:end=39,setpts=PTS-STARTPTS[fadeoutsrc]; [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip]; [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc]; [fadeinsrc]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[fadein]; [fadeoutsrc]format=pix_fmts=yuva420p, fade=t=out:st=0:d=1:alpha=1[fadeout]; [fadein]fifo[fadeinfifo]; [fadeout]fifo[fadeoutfifo]; [fadeoutfifo][fadeinfifo]overlay[crossfade]; [firstclip][crossfade][secondclip]concat=n=3[output]; [0:a][1:a] acrossfade=d=1 [audio]" -map "[output]" -map "[audio]" "outputs/240p.mp4"
