• 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 :

  But still no luck. The .mp4 will play in every compatible device/browser combination I have tried except for chrome.. Any advice ?

  TIA.

  Enable early termination in rd search

  This commit allows encoder to detect the cumulative rate-distortion
  cost per transformed block inside a partition. If the cumulative
  rd cost is already above the best rd value, it terminates the rest
  operations and continue to next prediction mode test.

  It reduces the runtime of bus at target bit-rate 2000 from 308 second
  to 266 second, i.e., about 13% speed-up at no performance penalty.

• .mov conversion to .mp4 using ffmpeg doesn't convert the entire video

  5 février 2013, par user504879

  I am trying to convert a mov file which I got from saving my powerpoint presentation to a movie file. However only a part of the presentation is converted not the entire one and also running qt-start doesn't make the exported mp4 to stream over rtmp. Is there something which I am missing ?

  I am attaching the output which i get when I am trying to convert the file using ffmpeg
