I was trying to set up cclookup, but I'm facing an issue It says "Browsing file ....' but it doesnt have the 'file:///' prefix, hence it tries to open the file in terminal as a executable. Any ideas how to avoid this behaviour. Please do email me back Thanks Shashank Thanks for making pylookup!

It says “Browsing file ….’
but it doesnt have the ‘file:///’ prefix, hence it tries to open the file in terminal as a executable.

Could you please tell me what commands I should run? thanks Hsu Hi Taesoo Kim;

I’m a bit buffled at the Step 2

Prepare to configure
Link avcodec.h, avformat.h, avio.h, avutil.h and swscale.h in the /usr/include/ffmpeg (you have to create) like below.

Could you please tell me what commands I should run?

thanks
Hsu

The error msg said you don't have mjpeg anymore. It should work, good luck! Could you check your “CV_FOURCC(’M',’J',’P',’G')” and try different codecs. The error msg said you don’t have mjpeg anymore. It should work, good luck!
