If you have it using higher bitrate does it work better? If you set the buffer to have a min and a max about a 10% the desired bitrate, does it work better? The ratecontrol isn't omniscient so it is expected to fail with impossible constraints. lu -- Luca Barbato Gentoo/linux http://dev.gentoo.org/~lu_zero _______________________________________________ libav-tools mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-tools
