#1398: remuxed DTS audio won't play on hardware devices -------------------------------------+------------------------------------- Reporter: patters | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: DTS audio | Blocked By: remux | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi, Firstly thanks for FFmpeg, it's an incredible tool. My interest in it comes from using the DLNA server Serviio which uses FFmpeg for its transcoding and remuxing. Many renderer devices don't support Matroska files but the streams they contain are often supported, so it's common to remux to mpeg-ts. I maintain the Serviio device profile for Sony Bluray and Network Media Players: http://forum.serviio.org/viewtopic.php?f=11&t=2004 I would like to report an issue with DTS audio streams that are remuxed into mpeg-ts by FFmpeg. The resulting files fail to play on many consumer electronics products which do officially support DTS, in my case Sony Bluray players, though I can see from the Serviio forum that it's also an issue for people who use AV receivers to decode the DTS stream. The files that FFmpeg produces play with silent audio on the affected devices, but they do play ok in VLC and Media Player Classic Home Cinema. I have observed this problem now for quite some time (maybe 18 months or so). I have reproduced this using the latest win32 build I could find from Zeranoe - ffmpeg-20120601-git-8a0efa9-win32-static.7z The remux command line that Serviio would issue is as follows: {{{ffmpeg -i "/volume1/public/video/Movies/The.Good.The.Bad.And.The.Ugly.EXTENDED.1966.BluRay.720p.DTS.x264-FSiHD.mkv" -y -async 1 -vcodec copy -vbsf h264_mp4toannexb -copyts -acodec copy -map 0:0 -map 0:1 -sn -f mpegts /volume1/@tmp/Serviio/transcoding- temp-1086-10-ORIGINAL.stf}}} The problem is not limited to my choice of example clip - I have found it to be consistent with all MKV files containing DTS audio. By contrast, the closed source utility [[http://www.videohelp.com/tools/tsMuxeR|tsMmuxeR]] is able to remux the same test clip in a way that plays perfectly on all systems I have tested. I shall attach 10MB clips of the original file, the FFmpeg non-working remux, and the TSmuxer working remux so that they may be analysed and compared. Hopefully this could lead to a fix, as it doesn't seem that this issue has been reported. Thanks, Patters -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1398> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#227(FFmpeg:new): Extend -ss and -t to support seeking to EOF time position (and backwards)?

#227: Extend -ss and -t to support seeking to EOF time position (and backwards)? --------------------------+--------------------------------------- Reporter: burek | Owner: michael Type: enhancement | Status: new Priority: wish | Component: FFmpeg Version: git | Keywords: seeking eof time position Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 --------------------------+--------------------------------------- Maybe, it would be useful if options -ss and -t could support something like this: ffmpeg -ss EOF-00:00:10 -i input ... (meaning the start time is 10 seconds before the end of the file). This would be useful in automated use of ffmpeg, where users don't need to set time positions absolutely (manually), but rather relatively to the end of file. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/227> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#933(FFmpeg:new): A/V desynch when transcoding A/V files with timestamps non starting from 0 with -copyts

#933: A/V desynch when transcoding A/V files with timestamps non starting from 0 with -copyts -------------------------------------+------------------------------------- Reporter: saste | Owner: Type: defect | Status: new Priority: normal | Component: FFmpeg Version: git- | Keywords: timestamp master | desynch mpegts Blocked By: | Blocking: Reproduced by developer: 1 | Analyzed by developer: 0 -------------------------------------+------------------------------------- Using the command: {{{ ffmpeg -vsync 0 -copyts -i columbia-intro.ts -acodec libfaac -y columbia- intro.out.ts }}} (same without -vsync) the A/V streams in the output file result desynched, and will result in the video being unplayable. This seems due to the first audio packet timestamp information not being correctly propagated to the encoder (and to the muxer), and being set to 0, so that ffmpeg will fill the first part of the file with audio packets, and the probe will fail since ffmpeg can't detect video frames in the probed initial part of the file. Same result in case I use the -copyts with no -vsync. If the output file only contains video (e.g. if the -an switch is used) the output file seems to be correctly generated (playable and with correct timestamp information). I'm attaching a sample file and log obtained by adding debugging print in ffmpeg.c. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/933> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1600: remux of xdcam mxf to mov is unplayable in Final Cut Pro --------------------------------------+---------------------------------- Reporter: dericed | Type: defect Status: new | Priority: normal Component: undetermined | Version: 0.10.4 Keywords: mov | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------------+---------------------------------- Summary of the bug: I would like to rewrap MXF files from an XDCam disc to QuickTime for edit in Final Cut Pro. I ran: ffmpeg -report -i /Volumes/XDCAM8004602012511C8/Clip/979_0611_01.MXF -map 0:v -an -c copy 979_0611_01.mov. The resulting file works in QuickTime, VLC, ffplay, etc, but when I open it in Final Cut Pro I get an error "File Error: Unknown File". I looked in the edts/elst atom and see Track Dur,Media Time,Media Rate 66,-1,1.0 17318,3003,1.0 When I change the first row to zeros it works. Note, when I run the same process in ffmbc the resulting file does not have the first line with the -1 media time, but only the "17318,3003,1.0" line and works in FCP as expected.
