  I'm currently trying to generate a video from a single picture (1980*1024)
  Here my cmd :

  ffmpeg -threads 8 -r 1 -loop 1 -i "C:\Library\Titling\__Resources\1.jpg" -t 5.00 -pix_fmt yuv420p -vcodec libx264 -b:v 1500k -s 720:576 -aspect 1.0000 -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4"

  here cmd execution :

  At this step I have two problems :
  first is a warning during execution
  deprecated pixel format used, make sure you did set range correctly
  The second is the video do not work correctly in VLC (video is "black") but it work in wmp...
  

  Then I add an empty audio track :

  ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"

  After that I concat this video to others using complex filter .
  When I concat my videos I have this message :
  

  [output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.

  And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
  perhaps it is not related
  I don't know ...

  Here my concat command and execution log
  

  D:\test>ffmpeg.exe -threads 8 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary0.mp4" -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4" -i "D:\Records\2013-10-11_115

• Converting avi to mp4 ffmpeg

  26 octobre 2013, par Dirk Swarz

  I use php code :

  $ffmpeg_command ="ffmpeg -i ".$new_name." -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 ".$anew_name;

  $convert_avi = true ;

  i know that the problem is in here :

  -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5

  Idea is when video is converted i can watch it via flash player and now flash player is saying that video is not found or bad syntax so obviuos its bad syntax but i dont know how to fix it

• FFMpeg slowed down sound sounds too metalic

  8 mars 2015, par user1571299

  this is the command line I use :

  ffmpeg -i VID_20150216_185018.mp4 -filter_complex setpts=4*PTS;atempo=0.5,atempo=0.5 output.mp4

  The video plays just fine and the audio is in sync...but it’s just too metalic compared with most slo-mo videos I’ve seen out there.
  Here’s an example how someone fixes it with Sony Vegas which is exactly what I want to achieve :
