• Compiling Static FFMPEG Binary

  8 octobre 2015, par Nino Ninkovic

  I cannot seem to compile a static build of FFMPEG. All of my attempts result with a ffmpeg binary that looks for libraries outside of the binary. Does anything stand out in my configure options ?
  Some further details - On OSX 10.10.5 and  Xcode7. I used homebrew to build all of the dependencies in '/usr/local/Cellar/ffmpeg/2.8/' I then used the same compile options that the homebrew install used and extended it with further options.

  Compiling goes without a hitch. The only issue being the ffmpeg binary is not static. I tried specifying --disable--share --enable-static with no luck (though i’ve read that these are on by default and do not need explicit specification)

  ## Compile Options ##

  Is there somethign glaringly wrong in my configuration ? Is it a licensing thing - where certain libraries wont compile statically ?
  I deeply appreciate any guidance in compiling a static ffmpeg binary.

  Thanks for your help !

• Error while trying to create dashcast stream using libx265

  16 décembre 2015, par Rahul

  I’m trying to create a h265 encoded stream from webcam using the follwoing command.

  DashCast -vf video4linux2  -v4l2f mjpeg -v /dev/video0 -conf dashcast.conf -live-media

  The content if dashcast.conf is

  But I’m getting this error.

  What could be the problem ? Changing codec to libx264 in the conf file works fine.
