#9316: nnedi af mode causes flicker at top and bottom row -------------------------------------+------------------------------------- Reporter: Tom B | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I'm using the following filter: -vf nnedi=weights.bin:all:af This generally works great, however, when converting 50i to 50p footage it causes a flicker at the top and bottom field in most frames. It seems that odd frames are simply black. It would be good if it used a bob/weave here as the result is distracting. yadif=1 produces worse results overall (e.g. scrolling text looks horrible) but does not produce this same flicker. This doesn't just happen on PAL videos like this with a black half row at the top/bottom. It happens on any video when `af` is specified. Using `a` mode works fine but obviously drops 50% of frames. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9316> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#9314(avcodec:new): Usage-of-uninitialized value
by FFmpeg 02 Jul '21

02 Jul '21

#9314: Usage-of-uninitialized value -------------------------------------+------------------------------------- Reporter: Andrew Bao | Type: defect Status: new | Priority: important Component: avcodec | Version: Keywords: Usage-of- | unspecified uninitialized value bug | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: In libavcodec/vorbisec.c, function vorbis_encode_init(): It partially initializes the structure vorbis_enc_context, leading to the memory pointed by venc in an uninitialized state. Details: In function vorbis_encode_init(), it will initialzie structure vorbis_enc_context by calling create_vorbis_context(). However, it initalizes all the field except struct FFBufQueue bufqueue. {{{ struct FFBufQueue { 50 AVFrame *queue[FF_BUFQUEUE_SIZE]; 51 unsigned short head; 52 unsigned short available; /**< number of available buffers */ 53 }; }}} Then bufqueue will be used in several places: move_audio(): {{{ 1073 cur = ff_bufqueue_get(&venc->bufqueue); }}} vorbis_encode_frame(): {{{ 1107 ff_bufqueue_add(avctx, &venc->bufqueue, clone); 1112 need_more = venc->bufqueue.available * avctx->frame_size < frame_size; 1119 if (venc->bufqueue.available * avctx->frame_size < frame_size) { 1120 int frames_needed = (frame_size/avctx->frame_size) - venc->bufqueue.available; 1128 ff_bufqueue_add(avctx, &venc->bufqueue, empty); }}} Since venc->bufqueue are not initialized, the fields {{{ unsigned short head; unsigned short available; }}} are undecidable. It might be set to zero or a random value inherited from the previous stack. In this case, if the variable available and head are set to random values, it will cause the program: 1. array read out of bound, leading to crash {{{ AVFrame *ret = queue->queue[queue->head]; }}} 2. arbitrary memory write, leading to crash or code execution {{{ BUCKET(queue->available++) = buf; }}} 3. Change control flow if (venc->bufqueue.available * avctx->frame_size < frame_size) { 4. change variable, running out of memory : {{{ int frames_needed = (frame_size/avctx->frame_size) - venc->bufqueue.available; for (i = 0; i < frames_needed; i++) { AVFrame *empty = spawn_empty_frame(avctx, venc->channels); }}} recommend fix: initialized struct FFBufQueue bufqueue during initialization -- Ticket URL: <https://trac.ffmpeg.org/ticket/9314> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
