I changed the condition in *_precompute_partition_info_sums_*() functions from if(bps <= 16) to if(FLAC__bitmath_ilog2(default_partition_samples) + bps < 32)
and then changed the 'subframe_bps' argument of find_best_partition_order_() in evaluate_fixed_subframe_() and evaluate_lpc_subframe_() as follows: evaluate_fixed_subframe_(): evaluate_lpc_subframe_(): 1) subframe_bps + order subframe_bps + 0 2) subframe_bps + order subframe_bps + 2 3) subframe_bps + order subframe_bps + 4 4) subframe_bps + 4 subframe_bps + 4 Version 0 hangs during encoding. So Miroslav was right, it is necessary to increase bps for lpc subframes as well. Versions 1...3 have identical encoding speed. So it's possible to play safe and just choose "subframe_bps + 4" in both cases. This is equivalent to the patch in http://lists.xiph.org/pipermail/flac-dev/2014-June/004771.html (this patch also adds 4 to subframe_bps, but in different place). So I think it's a matter of taste which patch to prefer: this -- http://lists.xiph.org/pipermail/flac-dev/2014-June/004771.html or this -- http://lists.xiph.org/pipermail/flac-dev/2013-July/004303.html _______________________________________________ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
