Comment (by atorp):
Hi lizhong1008,
I think you need to add this change:
{{{
#if QSV_HAVE_ICQ
+#if QSV_HAVE_QVBR
else if (avctx->global_quality > 0 && !avctx->rc_max_rate) {
+#else
+ else if (avctx->global_quality > 0) {
+#endif
rc_mode = MFX_RATECONTROL_ICQ;
rc_desc = "intelligent constant quality (ICQ)";
}
#endif
}}}
And regarding your patch https://patchwork.ffmpeg.org/patch/12935/ it
doesn't work.
Any other solution?
