It's a bug in libx265 that has been resolved some time ago. I guess you're using the libx265 from your distribution (e.g. Fedora) and they're behind. The solution is to compile libx265 yourself from git HEAD. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
