From 39a9fdd00fea6d2e40d4b9ecba38337549603a7d Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Wed, 30 Jan 2013 14:33:53 +0100 Subject: [PATCH] yop: initialize palette to 0 The FATE sample contains some pixels with value 0, but the palette stored in the file contains only values from 16 up. Because the default and cmdutils get_buffer() initialize the data to 0x80, they appear as gray dots. After this commit they change to black dots, which is probably still incorrect but less visible and doesn't rely on get_buffer() initializing the data. --- libavcodec/yop.c | 3 +++ tests/ref/fate/yop | 6 +++--- 2 files changed, 6 insertions(+), 3 deletions(-) diff --git a/libavcodec/yop.c b/libavcodec/yop.c index 3959ada251..fd7f090839 100644 --- a/libavcodec/yop.c +++ b/libavcodec/yop.c @@ -206,6 +206,9 @@ static int yop_decode_frame(AVCodecContext *avctx, void *data, int *got_frame, return ret; } + if (!avctx->frame_number) + memset(s->frame.data[1], 0, AVPALETTE_SIZE); + s->dstbuf = s->frame.data[0]; s->dstptr = s->frame.data[0]; s->srcptr = avpkt->data + 4; diff --git a/tests/ref/fate/yop b/tests/ref/fate/yop index 57f565d5f8..1a5666069e 100644 --- a/tests/ref/fate/yop +++ b/tests/ref/fate/yop @@ -1,7 +1,7 @@ #tb 0: 1/12 0, 0, 0, 1, 302760, 0x78939253 0, 1, 1, 1, 302760, 0x534f5253 -0, 2, 2, 1, 302760, 0xe991aa82 -0, 3, 3, 1, 302760, 0xc34b20bd -0, 4, 4, 1, 302760, 0x461d29a1 +0, 2, 2, 1, 302760, 0x25eaa782 +0, 3, 3, 1, 302760, 0x60861c3d +0, 4, 4, 1, 302760, 0x43552521 0, 5, 5, 1, 302760, 0x45abca02
