davs2_decoder_close doesn't free those on the fly frames which don't get output yet. It's a design bug, but easy to workaround. Before the patch: Direct leak of 1198606 byte(s) in 2 object(s) allocated from: #0 0x563af5e1e5f0 in malloc (ffmpeg+0x6675f0) #1 0x563af9765ef3 in davs2_malloc davs2/source/common/common.h:1240 #2 0x563af9765ef3 in davs2_alloc_picture davs2/source/common/header.cc:815 Indirect leak of 3595818 byte(s) in 6 object(s) allocated from: #0 0x563af5e1e5f0 in malloc (ffmpeg+0x6675f0) #1 0x563af9765ef3 in davs2_malloc davs2/source/common/common.h:1240 #2 0x563af9765ef3 in davs2_alloc_picture davs2/source/common/header.cc:815 Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>
