Hello,

Apparently you need to enable libpvx when you run configure according to the second answer here https://stackoverflow.com/questions/11003420/ffmpeg-unable-to-find-encoder-libvpx

[luckypoem]

but how to enable libpvx ? use what command to enable libpvx ?

[luckypoem]

oh,i know how to enable libpvx ：
cd ffmpeg-3.2.4
./configure --enable-libvpx
make
make install

but at later steps,i still encounter error:
cd /usr/local/prosopopee-site/example

root@localhost:/usr/local/prosopopee-site/example# ls
