Source: a DVD-9 which cannot be used with the standard ripping and transcoding applications, such as dvdbackup or streamdvd. Objects in mirror may be larger than they appear. Some settling of contents may occur during shipping. I have described some operands, briefly, and they should not be depended upon as a sole source of information. Let's not call it a "HOWTO" since it really isn't.ĭisclaimer: Prior to using any of these programs, it is an absolute must to read their man pages, and perhaps peruse other available documentation. Here are my notes from this particular process. vob produced by -dumpstream has no VOB Units, which mplex will provide, and the video stream needs to be run through tcrequant to fit a DVD-5. This explains why elemental streams (needed for mplex/dvdauthor) don't sync.Īny suggestions for getting sync'ed elemental streams? With every new PSU, PTS/DTS gets reset, IIRC. If I run tcdemux with -W, I get 9 presentation units througout the content. If I use the default 1 MB, it shows 5 presentation units and all in sync.
Note that it shows 6 presentation units when probing the first 30 MBs. I'm NOT close enough, as mplayer only jumps by +/100ms.
After running mplex with 0 delay, the difference (through using mplayer's + and - keys to try to get close) in the a/v streams is around 1.7 or 1.8 seconds. D 4 -av_fine_ms 22 (frames & ms) Īudio track: -a 1 -e 48000,16,2 -n 0x2000 ĭetected (6) presentation unit(s) (SCR reset)Īccording to tcprobe, the difference in start time between video and audio is 0.1895 seconds. summary for rip.vob, (*) = not default, 0 = not detected vob show these sync differences: MPEG program stream (PS) Unfortuately, the elemental streams do not sync up. I had hoped to demux A/V into ac3 and m2v files, then use mplex and dvdauthor in preparation for burning. I used:mplayer dvd://16 -dvdangle 2 -dumpstream -dumpfile rip.vobThis vob plays in perfect sync. The main content is title # 16, a multiangle PGC with 2 audio and 3 subtitle tracks. *** libdvdread: CHECK_VALUE failed in libdvdread4/nav_read.I am struggling with a vob obtained through mplayer's -dumpstream facility, as my normal rippers, dvdbackup and dvdstream, are unable to deal with this particular disc (RipGuard protected). endpos also accepts the pretty 00:01:40 style format. so in this example we are starting 100 seconds in and ending 60 seconds later (at 160 seconds). supposedly you can also do like 00:01:40 for 100 seconds (1 minute 40 seconds). Last is the -ss argument which is how far in to start, 100 seconds here. then you can just upload that to youtube or whatever when mplayer finishes. here i put it on my desktop and call it myrun.vob. otherwise keep typing.Īfter -dumpstream -dumpfile is the path to the new file you are making with the part of the run cut out. if you want to preview what title it is you can hit enter now and it will pop up a window showing that title (hit q to get out). can drag and drop the folder into the terminal so you don't have to actually type the path. Second line after -dvd-device is the path to your VIDEO_TS folder. otherwise you'll need to adjust it to point to your mplayer binary executable.
#MPLAYER DUMPSTREAM MAC#
if you're on a mac and put mplayer os x extended in your applications folder then it should be identical for you, can just copy and paste. it's just to keep the parts of the command separate and easier to look at and talk about.įirst line is just the path to mplayer. I end each line with backslash - that's to stop it from executing the command until you end a line without a backslash.
dumpstream -dumpfile ~/Desktop/myrun.vob \ Applications/MPlayer\ OSX\ Extended.app/Contents/Resources/Binaries/mpextended.mpBinaries/Contents/mpextended.mpBinaries/Contents/MacOS/mplayer \
normally mplayer is really hard to use from the command line but for what we are doing it won't be bad.įirst you need to either insert the dvd or otherwise have the VIDEO_TS folder accessible somewhere on your hard drive. Once you have it in your applications folder then you can invoke it via the command line (terminal) too.
#MPLAYER DUMPSTREAM DOWNLOAD#
If you're on a mac and don't have mplayer you can download it here: in fact, it comes with anri - look under c:\programs\anri_whatever\ for mplayer.exe. This document pertains primarily to unix (mac os x, linux, etc) users, though you can use mplayer under windows, too.
