Sorry, I have another question about OpenJPEG: How may I build FFmpeg with OpenJPEG support ? I tried: /configure --enable-libopenjpeg --extra-cflags="-DHAVE_OPENJPEG_2_0_OPENJPEG_H" but configure complains that libopenjpeg is not found. This is on a ubuntu system. Any guidance would be greatly appreciated. Thanks, Aaron
