TypeError : Cannot read properties of undefined (reading 'format')

  


  I think is because ffmpeg is not connecting to mongodb

  


• Video editor for android - FFmpeg won't compile on windows ?

  4 décembre 2014, par Zoe

  Im trying to make a video editor for android (I’ve never made an android app before)

  After searching for libraries to use I came across FFmpeg but I’m having trouble getting it to compile on Windows 7.

  I’m currently using Eclipse and have the most recent android SDK and ndk.

  I’ve been trying to follow tutorials on the internet including roman10’s (http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/) but they all seem specific to Linux.

  Yesterday, I thought I’d give up and just dual boot Ubuntu on my windows laptop but of course that was messing up too. I shrank my partition and booted Ubuntu of a USB but the installer was detecting there is no OS on my laptop and not giving me the option to install it alongside windows 7.

  So, can FFmpeg be compiled for android on windows ? Or is there another library I could use to make a video editor that can ?

  Or should I just persist with dual booting ubuntu ?

  Thanks
