What packages should I install in Ubuntu > 18.04 (it has many packages called libopencv*) and should I build ffmpeg from > source? Try installing the core library then configuring. _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
