Persistent Error: Cannot find H264 Encoder #1

Open k-g opened 10 years ago

k-g commented 10 years ago

I'm trying to run this package on Ubuntu 12.04 LTS, but I seem to always get this error:

"Unable to find H264 encoder, ffmpeg version too old ?"

I've tried uninstalling the default Ubuntu x264 lib along with ffmpeg and compiling/installing both from source, still with the same effect.

Any tips? I'd really like to be able to use this but am a bit lost. Maybe I'm not using the right versions of everything?

I run: Ubuntu 12.04 ROS Fuerte libx264.so.138 libavcodec.so.53

The problem comes from the fact that older ffmpeg versions do not include the H.264 encoder (and you had to use libx264 separately) . It should now be available with newer versions.

Thanks! I figured out the problem and have it working.

I was not using the proper compilation flags on libx264 and ffmpeg, so shared libraries were not getting generated. I'll try to find the exact line I used and provide it for future reference.
