<div dir="ltr">Hi Prashanth<br><br>I advise that you'd better to change the function "x264_mb_analyse_load_costs". I changed the function from "x264_mb_analyse_load_costs( x264_t *h, x264_mb_analysis_t *a )" to "x264_mb_analyse_load_costs( x264_t *h, x264_mb_analysis_t *a, int i_end )".<br>
<br>In the origin function you should set parameter "i_end" to 0. At the end of the encoding you should call the function and set the "i_end" to 1. Belows are new function:<br>static void x264_mb_analyse_load_costs( x264_t *h, x264_mb_analysis_t *a, int i_end )<br>
{<br> static int16_t *p_cost_mv[52];<br><br> if(i_end == 1)<br> {<br> int j;<br> for(j=0; j<52; j++)<br> if(p_cost_mv[j])<br> {<br> x264_free(p_cost_mv[j] - 2*4*2048);<br>
p_cost_mv[j] = NULL;<br> }<br> <br> return;<br> }<br><br> if( !p_cost_mv[a->i_qp] )<br> {<br> /* could be faster, but isn't called many times */<br> /* factor of 4 from qpel, 2 from sign, and 2 because mv can be opposite from mvp */<br>
int i;<br> p_cost_mv[a->i_qp] = x264_malloc( (4*4*2048 + 1) * sizeof(int16_t) );<br> p_cost_mv[a->i_qp] += 2*4*2048;<br> for( i = 0; i <= 2*4*2048; i++ )<br> {<br> p_cost_mv[a->i_qp][-i] =<br>
p_cost_mv[a->i_qp][i] = a->i_lambda * bs_size_se( i );<br> }<br> }<br><br> a->p_cost_mv = p_cost_mv[a->i_qp];<br>}<br><br>Best wishes,<br>Alexander tian<br><br><br><br><div class="gmail_quote">
