Hello there. :) For the past week I've been struggling to get a clean MPEG-PS stream from my "Stargate (Ultimate Edition)" DVD. I've used plain old 'mplayer dvd://1 -dumpstream' on the machine I'm typing this on. ( Kubuntu Linux 8.04 ) I've used the latest version ( 6.5.0.7 ) of AnyDVD HD in Win XP SP3 under the latest version of VMWare 6.5 on this same machine. Also, I've used AnyDVD HD on another machine with a native Windows install. I get the same result in all cases : when the stream or .VOB files are played using Mplayer, the error/warning/debug output complains of constant FILM<->NTSC frame rate changes, constant NTSC<->Progressive NTSC content changes, "Warning! FPS changed" and other miscellanea. Also, when playing the physical DVD from the drive with eg, 'mplayer dvd://1 -fs' *I get the exact same errors and warnings*. Just to be absolutely sure, I compiled the latest versions of libdvdread and libdvdnav from the Mplayer home page and I used Subversion to checkout the latest snapshot of Mplayer and compiled it with the './configure --enable-gui --disable-dvdread-internal' options. ( The latter option is needed so that Mplayer doesn't use its built-in versions of libdvdread and libdvdnav and instead compiles against the versions already installed on your system ) The result : same errors.
I still haven't explained why I care about the above errors. Let me do so now. The purpose of my quest to get a clean MPEG-PS rip is so that I can transcode a small portion of it using the latest version of Avidemux. But, when any of the above rips are loaded into Avidemux and played, I get horribly out-of-sync video/audio along with choppy video : eg. continuous stuttering out-of-sync audio with jumpy video. After some research, I discovered that the DVD itself could have been crapilly mastered, resulting in a mix of either Telecined and progressive content or interlaced and progressive content. But, when single stepping through each frame of the video *I do not see the Telecine pattern, nor any pattern at all, or any interlacing for that matter*.
One interesting tidbit is that Mplayer can play *all* of the above stream dumps and/or .VOB files, including the physical DVD via 'dvd://1' *flawlessly* .
So basically, I'm at a loss as to what to do.
I've attached the error/warning/debug output of ' mplayer -msglevel all=9 -identify stream.dump 1>log.txt 2>&1 ' . ( note that the text file is doubly compressed : log.zip -> log.txt.tar.bz2 -> log.txt )
If anyone can help me I'd be greatly appreciative.
Thanks,
