• FFMPEG - Correct command line parameters to create a H.264 Streaming MP4 from a set of images

  5 janvier 2012, par Adam

  I have no problems viewing a video created by my current parameters in a HTML5 browser, Flash player, Windows Phone 7, Android Phone, etc. However, they won't display on iPhone or iPad. If I modify the video using Super and select "Enable Streaming" checkbox they work on iPhone and iPad suddenly. We are suspecting that my command line parameters are incorrect for enabling h.264 streaming and are instead generating a "progressive download" video.

  I'm pretty new to FFMPEG and don't understand a lot of the parameters. Can anyone help correct my existing parameters, or maybe provide the missing parameters, etc ?

  Thanks in advance.

  My current FFMPEG command line paramters are :

  ffmpeg.exe 
   -r 30 
   -threads 4 
   -f image2 
   -i .\frame%05d.jpg 
   -i audioFile  
   -acodec aac 
   -ab 128k 
   -ar 44100
   -vcodec h264 
   -crf 27 
   -coder 1 
   -flags +loop 
   -cmp +chroma 
   -partitions +parti4x4+partp8x8+partb8x8 
   -me hex 
   -subq 5 
   -me_range 16 
   -g 60 
   -keyint_min 25 
   -sc_threshold 40 
   -i_qfactor 0.71 
   -b_strategy 1
