#1755: Audio becomes silent on some avi files.

Video end at about 31 sec but audio stopped about 12 sec. I reviewed audio and video PTS information using ffprobe tool. Please refer the PTS plotting graph as below. (Notice! Recommend download of PTS plotting file because of Google docs excel inter-operability) * PTS plotting link : https://docs.google.com/open?id=0B6r7ZfWFIypCbnRtVlFTVVA0cEU * Problematic file link : https://docs.google.com/open?id=0B6r7ZfWFIypCeXB3b2J5S1NDMzQ My Analysis of PTS - Video PTS is OK. - Audio PTS is NG. - Whole timeline of this media file is about 31 sec but audio pts has about 12 sec timeline. - Also values of Audio PTS are grouped as special pattern. - Simplified Audio PTS pattern : 0, 0, 0, 1, 1, 2, 2, ……. , N/3 - Simplified Video PTS pattern : 0, 1, 2, …. , N -> The shape of audio PTS make 2 problem. 1) Audio stop early. Because audio PTS by ffmpeg have 12 sec but real audio has 30 sec. 2) Seek does not work after 12 sec. - My co-worker checked audio PTS information of problematic based on avidemux and Audio PTS is just OK. - And so I request that FFmpeg team inspect this problem.

#1762(avformat:new): mp4 file with 2 'mp4a' boxes in a 'stsd' box

#1762: mp4 file with 2 'mp4a' boxes in a 'stsd' box -------------------------------------+------------------------------------- Reporter: chungying | Type: defect Status: new | Priority: normal Component: avformat | Version: Keywords: mp4 mp4a | unspecified stsd | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: There is a mp4 file with 2 'mp4a' boxes in a 'stsd' box. Acording to ISO IEC 14496-12, the 'sample_description_index' field in 'tfhd' box gives the index of the sample entry in 'stsd' box. However, in 'ff_mov_read_stsd_entries' always takes the information of the last 'mp4a' box instead of read the 'sample_description_index' field. Maybe the information of stsd can be recorde as a list and apply the information indexed by 'sample_description_index'. How to reproduce: The file I attached always without sound output. Since the value of 'sample_description_index' field in this file is '1', but the information applied is in the second 'mp4a' box. (The number of entries start from 1.) -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1762> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1263(FFmpeg:new): ffmpeg keeps the output file in memory and only writes it to disk after [q]uitting

#1263: ffmpeg keeps the output file in memory and only writes it to disk after [q]uitting -------------------------------------+------------------------------------- Reporter: pmts | Type: defect Status: new | Priority: normal Component: FFmpeg | Version: git- Keywords: memory dts | master mkv | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Tested with current git and 0.10.2. 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'.
