From 900321b08c95bd42e6db53864bfffbe48d6019da Mon Sep 17 00:00:00 2001 From: elupus Date: Fri, 22 Apr 2011 15:42:51 +0200 Subject: Don't mark generated dummy frame output from mpeg1/2 decoder as keyframe. We use this flag to tell when to assume decoded data is free from artifacts after a seek. The mpeg1/2 decoder will generate a dummy frame if decoding is started on a non keyframe. This will sadly be output from decoder to player and displayed as a gray screen. --- libavcodec/mpegvideo.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'libavcodec') diff --git a/libavcodec/mpegvideo.c b/libavcodec/mpegvideo.c index d3540c961a..3749fd9bd3 100644 --- a/libavcodec/mpegvideo.c +++ b/libavcodec/mpegvideo.c @@ -1114,6 +1114,7 @@ int MPV_frame_start(MpegEncContext *s, AVCodecContext *avctx) /* Allocate a dummy frame */ i= ff_find_unused_picture(s, 0); s->last_picture_ptr= &s->picture[i]; + s->last_picture_ptr->key_frame = 0; if(ff_alloc_picture(s, s->last_picture_ptr, 0) < 0) return -1; ff_thread_report_progress((AVFrame*)s->last_picture_ptr, INT_MAX, 0); @@ -1123,6 +1124,7 @@ int MPV_frame_start(MpegEncContext *s, AVCodecContext *avctx) /* Allocate a dummy frame */ i= ff_find_unused_picture(s, 0); s->next_picture_ptr= &s->picture[i]; + s->next_picture_ptr->key_frame = 0; if(ff_alloc_picture(s, s->next_picture_ptr, 0) < 0) return -1; ff_thread_report_progress((AVFrame*)s->next_picture_ptr, INT_MAX, 0); -- cgit v1.2.3
