• ffmpeg : Generate video from picture

  16 octobre 2013, par Tchoupi

  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

• ffmpeg - How to determine if -movflags faststart is enabled ? PHP

  3 juin 2015, par IIIOXIII

  While I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.

  After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.

  To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.

  This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :

  exec($ffmpegPath." -help", $codecArr);
  
  for($ii=0;$iibr>';
  
  }

  Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?

  Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?

  TIA.

• FFmpeg can 'encode' to mp3, but will not accept an 'input' mp3

  21 novembre 2011, par Jonathan Coe

  FYI : Fedora 8 running on Amazon EC2...

  Having a difficult time with FFmpeg doing a (what should be pretty simple) conversion. I can get FFmpeg to encode an mp3 file from an m4a file using the following :

  ffmpeg -i file1.m4a -acodec libmp3lame -ab 160k file2.mp3

  However, I cannot get it to to convert an mp3 -> mp3, it responds with "Unknown Format" using the following :

  ffmpeg -i file1.mp3 -acodec libmp3lame -ab 160k file2.mp3

  I get the following command string :

  FFmpeg version UNKNOWN, Copyright (c) 2000-2008 Fabrice Bellard, et al.

  file1.mp3: Unknown format

  Any help would be hugely appreciated !

  Edit for clarity :
  The input file is in /ebs/queue/input.mp3 and the output is /ebs/converted/output.mp3
