[FFmpeg-user] "ERROR: libx264 not found" Ubuntu 11.10

Mon Feb 20 11:47:58 CET 2012

Both "sudo ls -al /usr/local/lib | grep libx264.so" and "sudo ls -al
/usr/lib/ | grep libx264.so" produce nothing after build and manual package
install.

cat /etc/ld.so.conf gives "include /etc/ld.so.conf.d/*.conf" which leads to
3 files that combine to form the following data:
/usr/local/lib
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/mesa

Whereis libx264.so now returns "libx264: /usr/local/lib/libx264.a"
I managed to successfully configure and make ffmpeg after this.
Thanks for your assistance!

However, when I try to run the following:
ffmpeg -i rtsp://[my source] -re -acodec libfaac -ar 22050 -vcodec libx264
-fpre "ffpresets/libx264-ipod640.ffpreset" -f flv rtmp://[my target]
I get "unknown encoder: 'libx264'".

ffmpeg was configured successfully with this command and make went by
without a hitch.
./configure --enable-gpl --enable-libfaac --enable-libmp3lame
--enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora
--enable-libvorbis --enable-libx264 --enable-nonfree --enable-postproc
--enable-version3 --enable-x11grab

The presetfile looks like this (not that I think it matters):
vprofile=baseline
level=30
maxrate=10000000
bufsize=10000000

Shuld I perhaps start a new thread since the topic no longer matches the
issue?
