[Libav-user] memory leak when I-frame is delayed

[Алексей Дорофеев]

I have my own simple h.264 test. Test reads YUV frames from file, encodes
to h.264 frames and after decodes. Test is leaking too. I've used valgring
and massif to get memory snapshots in runtime. There are two points where
memory is leaking:

->30.61% (13,777,514B) 0x1019308: av_mallocz (mem.c:93)
| ->21.78% (9,804,266B) 0xEAF177: av_fast_padded_malloc (utils.c:87)
