• HTML5 Video Chrome - ffmpeg - mp4 working in all but Chrome

  16 octobre 2014, par IIIOXIII

  I have successfully encoded a file to .mp4 using ffmpeg which will play in all tested devices (Safari on PC, IE on PC, Android Browser, Andriod Video Player, and Safari iPad), except for Chrome.

  As a work-around, I had planned to simply list the .ogg source prior to the .mp4 source so that chrome would play the .ogg source without even seeing the .mp4 source, however, I ran into the issue mentioned here.

  Basically, I am after the proper ffmpeg command which will encode an .mp4 video to standards which will play in Chrome - of course without losing playback functionality on any of the other previously mentioned platforms.

  I have tried several combinations, such as :

  ffmpeg -i [filename].wmv -vprofile baseline -level 30 -vf scale=640:-1 -movflags faststart [filename].mp4

  etc. but have not yet found the winning one.

  EDIT : I tried :

  ffmpeg_new -i [filename].wmv -strict experimental –acodec libvo_aacenc -ac 2 -ab 160k -vcodec libx264 -vf scale=640:-1 -pix_fmt yuv420p -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 [filename].mp4

  And here is the ffmpeg output :

• FFMPEG overlay issue for 2 videos, sound missing from second input

  7 septembre 2014, par Abhishek Singh

  I’m trying to achive an overlay with ffmpeg wich take the two flv files as input and make a output and both videos playing simultaneously. things are working fine with below ffmpeg command :

  ffmpeg -i input1.flv -vf "[in] scale=359:320, pad=2*iw+6:ih [left]; movie=input2.flv, scale=359:320 [right]; [left][right] overlay=365:0 [out]" -b:v 3600k -y output.flv

  But issue is with the sound of second video and that is missing from the output.flv, only input1 sound is available in the output.flv.

  Console output is :

• 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.
