#21: Segfault converting m2t file with ac3 audio track when number of audio channels changes. ------------------------+---------------------------------------------- Reporter: vk5ztv | Owner: michael Type: defect | Status: new Priority: important | Component: FFmpeg Version: git | Keywords: crash, segfault, invalid pointer Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 ------------------------+---------------------------------------------- When converting an m2t file with a 5.1 channel ac3 audio track to mkv, ffmpeg segfaults when the number of audio channels in the source stream changes. The source stream was recorded from DVB and during an ad break changes from 5.1ch audio to 2ch audio (and presumably back again at the end of the adverts). The command line used was: ffmpeg -y -i Summernats\ 2011.m2t -pass 2 -acodec ac3 -ab 512k -vcodec libx264 -vpre slow -vpre baseline -threads 0 -vsync 1 -b 2048k -bt 2048k -nr 400 -aspect 16:9 -s

It seems raicy, because it happens always without brekpoints, but sometimes it barely works stepping into it, but no threading involved (I guess).

I found this problem with version 26383 get from ffmpeg on windows autobuild site. ffplay set the pts for AVFilterBufferRef struct with output from guess_correct_pts function which is very small for example 67, 133 ,etc for the first several frames. But ffmpeg will set the pts for AVFilterBufferRef with very large rescaled value which is calculated by output_packet function's function following process. if(pkt->pts != AV_NOPTS_VALUE) pkt_pts = av_rescale_q(pkt->pts, ist->st->time_base, AV_TIME_BASE_Q); I added the log output code to vf_rotate's end_frame function like below. static void end_frame(AVFilterLink *link) { RotContext *rot = link->dst->priv; AVFilterBufferRef *in = link->cur_buf; AVFilterBufferRef *out = link->dst->outputs[0]->out_buf; int i, j, plane; #if 1 av_log(0, AV_LOG_ERROR, "rotate pts:%I64d\n", in->pts ); #endif ... } and used the command ffmpeg -i 1.avi -vf "rotate" 2.avi ffplay -vf "rotate" 1.avi confirmed the problem best regards ChinShou -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/17> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
