From 7e76e1ea80052ee95ef33d5341b9251b90766c9c Mon Sep 17 00:00:00 2001 From: Timo Rothenpieler Date: Sat, 11 Nov 2017 13:12:06 +0100 Subject: wmavoice: free frame before ff_get_buffer synth_superframe can be called twice per call to decode_packet. It is not fully clear if calling ff_get_buffer on the same frame twice is supported, so unref the frame first to be save. --- libavcodec/wmavoice.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/libavcodec/wmavoice.c b/libavcodec/wmavoice.c index 2ec4499..3f86d0d 100644 --- a/libavcodec/wmavoice.c +++ b/libavcodec/wmavoice.c @@ -1756,6 +1756,10 @@ static int synth_superframe(AVCodecContext *ctx, AVFrame *frame, stabilize_lsps(lsps[n], s->lsps); } + /* synth_superframe can run multiple times per packet + * free potential previous frame */ + av_frame_unref(frame); + /* get output buffer */ frame->nb_samples = MAX_SFRAMESIZE; if ((res = ff_get_buffer(ctx, frame, 0)) < 0) -- cgit v1.1
