This is a bugfix for ARMv4 assembly implementation of 'j_rev_dct' function. The problem was in the incorrect partially empty row detection. Even if the first two coefficients in the row were nonzero, it handled this just like the case with only the first nonzero coefficient. Now this function produces exactly the same output as the stripped down reference C version of 'j_rev_dct' (with the nested checks like 'if (d6) { if (d2) { ...' always evaluated as true, avoiding shortcut branches). Originally committed as revision 15805 to svn://svn.ffmpeg.org/ffmpeg/trunk |
