#66(avfilter:new): Leak in lavfi movie source

#66: Leak in lavfi movie source ------------------------+---------------------------------------------- Reporter: ferrieux | Owner: michael Type: defect | Status: new Priority: important | Component: avfilter Version: git | Keywords: overlay movie source memory leak Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 ------------------------+---------------------------------------------- I have discovered that the movie source has a systematic memory leak. Initially it hit me on realtime several-input side-by-side overlays, but I have tracked it down also in a non-realtime case with a single movie source. It is independent on the output codec nor container, and also disappears if one replaces the movie source by the 'color' trivial source. Details below. =========== COMMAND LINE ======================================== # ffmpeg_g.r29131git -flags low_delay -probesize 50000 -threads 3 -i flux.264 -vf ' movie=flux.264,setpts=PTS-STARTPTS [src1]; [in] setpts=PTS-STARTPTS, pad=768:288:0:0:red, [src1]overlay=384:0 ' -vcodec mpeg2video -strict experimental -r 15 -vb 8192k -f mpegts - =========== SYMPTOMS ================================================ The leak is steady, eventually using up all RAM.

#144(undetermined:new): ffmpeg 0.7c FFPLAY using CODEC_ID_H264 HUGE MEMORY LEAKS (1MB/s)

#144: ffmpeg 0.7c FFPLAY using CODEC_ID_H264 HUGE MEMORY LEAKS (1MB/s) -------------------------------+----------------------- Reporter: alexandru_mg3 | Type: defect Status: new | Priority: critical Component: undetermined | Version: 0.7-rc1 Keywords: h264 memory leaks | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | -------------------------------+----------------------- 1. I'm using ffmpeg 0.7c (your mt integrated version) taht I built with mingw32 2. I run an h264 stream (a TV Channel) with ffplay on Windows , a full HD one (1920x1080), from DREAMBOX the stream video-codec is : h264 - mpeg4 avc (part 10) (h264) 1920x1080 frame rate 50 the audio codec is: a52 audio (aca ac3) (a52) 7.1 (I confirm this information runing also the stream with vlc too) 3. Command line : ffplay <h264-stream-url> (I run also another HD TV Channel having the same memory leaks) 4. BUG DESCRIPTION: during the playing, the memory quickly increased with aprox. 1MB/s, till the whole windows memory is exhausted after around 10-15min 4. I put some debug trackings and comments in ffplay and compiling again, I saw that : a. - the used codec is CODEC_ID_H264 b. - the place where additional memory is allocated is after each call to: " len1 = avcodec_decode_video2(is->video_st->codec, frame, &got_picture, pkt); " Note: the pkt is always well deallocated in ffplay code and the frame is deallocated only once at the of the loop in ffplay code, as usual) c. The memory leaks don't appear when playing non-hd channels (so when using other codecs) 4. Viewing how huge is the memory leaks are (1MB/s) Seems that the AVFrame is set to some internal pictures that are never de-allocated h264 decode_frame... *pict = *(AVFrame*)h->next_output_pic; But this is only a supposition, of course, could well be some other buffers... 5. Practically the h264 codec cannot be used in this case. and is the single way to play HD TV Channels due to the mt facility. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/144> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
