[FFmpeg-devel] can't get it to work on CentOS

[Matteo Sisti Sette]

I'm seeing that libopencore seems to be missing, but I do have the 
library installed (and had it when I compiled ffmpeg) and I did compile 
it with --enable-libopencore-amrnb --enable-libopencore-amrwb

With the versions of ffmpeg that work (ubuntu and CentOS):

  $ ffmpeg -formats | grep amr

  DE amr             3GPP AMR file format
  DEA    libopencore_amrnb OpenCORE Adaptive Multi-Rate (AMR) Narrow-Band
  D A    libopencore_amrwb OpenCORE Adaptive Multi-Rate (AMR) Wide-Band

With the version that does not work (CentOS, the one that I have just 
compiled from source):

  $ ffmpeg -formats | grep amr

  DE amr             3GPP AMR file format


What should I do to get libopencore support (besides installing 
libopencore and using the abovementioned --enable options)?


thanks
m.
