This seems to happen with one particular input file. I'm trying to remux that file using ffmpeg while transcoding a dts track into ac3. This transcoding seems to trigger the bug. While encoding ffmpeg started allocating huge amounts of memory, on the order of 100MB/s. At first I thought it's a memory leak, bu then I noticed it's keeping the output file in memory and only writes it to disk after I tell it to stop. My command line: {{{ffmpeg -i The.Good.the.Bad.and.the.Ugly.1966.720p.BluRay.HQF.mkv -vcodec copy -acodec ac3 -ab 448k -map 0:v -map 0:2 -map 0:6 -map 0:7 -map 0:8 -map 0:9 -scodec copy /mnt/auto/megamagazyn/filmy/The.Good.the.Bad.and.the.Ugly.1966.720p.BluRay.HQF.mkv}}} 0.10.2 didn't print any errors/warnings, but current git floods the screen with the following: {{{ DTS 15936, next:15984666 st:2 invalid dropping PTS 15936, next:15984666 invalid dropping st:2 DTS 15946, next:15995332 st:2 invalid dropping PTS 15946, next:15995332 invalid dropping st:2 DTS 15956, next:16005998 st:2 invalid dropping PTS 15956, next:16005998 invalid dropping st:2 DTS 15966, next:16016664 st:2 invalid dropping PTS 15966, next:16016664 invalid dropping st:2 DTS 15976, next:16027330 st:2 invalid dropping PTS 15976, next:16027330 invalid dropping st:2 DTS 15986, next:16037996 st:2 invalid dropping PTS 15986, next:16037996 invalid dropping st:2 DTS 15996, next:16048662 st:2 invalid dropping PTS 15996, next:16048662 invalid dropping st:2 DTS 16006, next:16059328 st:2 invalid dropping PTS 16006, next:16059328 invalid dropping st:2 DTS 16021, next:16069994 st:2 invalid dropping PTS 16021, next:16069994 invalid dropping st:2 DTS 16031, next:16080660 st:2 invalid dropping PTS 16031, next:16080660 invalid dropping st:2 }}} I'll attach a full verbose log, where I let it run for a couple of seconds and pressed 'q'.
