• ffmpeg : unsync audio after processing

  18 novembre 2013, par QuickSilver

  I am recording a video and using RecordRTC : WebRTC . After receiving the webm video and wav audio at server, I'm encoding it to a mp4 file using ffmpeg(executing shell command via php). But after encoding process, the audio is unsync with video (audio ends before video). How can I fix this ?

  js code is here

  ffmpeg command used is :

  ffmpeg -y -i 166890589.wav -i 166890589.webm -vcodec libx264 166890589.mp4

  Console output :

• ffmpeg on Heroku : unrecognized option 'preset'

  17 novembre 2013, par scientiffic

  I'm using ffmpeg version 1.2.4 in my local Rails app to convert video files. Everything works as expected when I run the app locally. When I deployed to heroku, I added a buildpack for ffmpeg :

  https://github.com/shunjikonishi/heroku-buildpack-ffmpeg

  This installs ffmpeg version git-2013-06-02-5711e4f. When I try to transcode a video to mp4, I get the following error :

  Unrecognized option 'preset'. Error splitting the argument list : Option not found

  Here is the complete log :

  I think that the error may be a result of differences in the version of ffmpeg that I'm using locally and on Heroku. Does anyone have suggestions for how to resolve this issue ?

• Getting ffmpeg to work with Heroku

  23 octobre 2016, par scientiffic

  I attempted to install ffmpeg for my Heroku Rails app and now my app is crashing.

  I added a buildpack using the following command :

  heroku config:add BUILDPACK_URL=https://github.com/shunjikonishi/heroku-buildpack-ffmpeg

  After pushing to Heroku, I get the following error according to my logs :

  When I check the version of bundler I’m using (bundle show bundler), I get :

  How can I solve this problem ?
