From a1dc0bdaf49497358d70002ffb5ec498f5f41270 Mon Sep 17 00:00:00 2001 From: Jerome Borsboom Date: Mon, 23 Apr 2018 21:00:08 +0200 Subject: [PATCH] avcodec/vc1: correct mspel for field-interlace B frames mspel indicates the use of bicubic interpolation. The check wrongly included MVMODE MV_PMODE_1MV_HPEL as using bilinear interpolation.
