[Mjpeg-users] DVD Studio Pro and MjpegTools
I'm not having much luck using material produced with the MjpegTools with DVD Studio Pro -- or any Apple product for that matter. So I was considering sending a negative note to Apple support, but then I recalled that there is at least one member of this group actively using to two software products together, so I figured this would be a more productive avenue. I'm using a recent CVS version of mjpegtools (I got tired of waiting for the followon to 1.6.2) -- 10/05/2004 to be precise. It's also a pretty recent version of DVD Studio Pro (Academic version), version 3.0.1. But really, I haven't had much luck with any of the Apple software reading mpeg-2 files created with the mjpegtools. The default version of Apple Quicktime won't even recognize mpeg-2 files at all. Fortunately, the Production Suite of tools that I purchased with my came with an upgrade to QuickTime Pro. Unfotunately however, while QT-Pro would recognize and read the files, it is not able to handle them at a respectible rate -- after the first few moments of one file I created the frame rate of displaying the video drops to between 2 and 7Hz. Whereas a version of mplayer that I downloaded for my Powerbook plays the file just fine. I should say that my Powerbook is a brand new 15 w/ Super Drive, and a 1.5GHz G4 processor. Also, the files I'm trying to play come from two sources -- a Canopus 100 capture via dvgrab, and using smilutils to feed into an mpeg2enc pipe and then multiplexed with the mjpegtoosl multiplexer -- at bitrates within the DVD specs. The other source is an IVTV capture from a Hauppauge PVR-350. In that case, the capture was at bitrates above DVD spec, so I use mpeg2dec to decode them, piped through pgmtoy4m, filtered, and then reencoded with the mjpegtools mpeg2enc program, and again mplexed. Oh, I use avidemux2 on the latter to trim the beginning and end of the TV capture, and then save the files as Audio and a separate Raw video stream. I did manage to make a very simple DVD with dvdauthor from an mpeg-2 file that went through the latter process, and it plays on my set-top player. But I would like to make more complicated DVD's, and take advantage of this rather expensive software that I purchased. Enter DVD Studio Pro. When I try to import the asset of one of these multiplexed mpeg-2 video files, I get a popup that tells me: Alert: Import Assets Could not import one file. Incompatible Format Not a particularly informative message, much less what I was expecting to happen -- at least Quicktime Pro can read and play the file, if poorly. I then tried iDVD, and it's a little more informative, but no more successful: Unsupported File Type: MPEG Video [in bold] I find that an ironic statement coming from a program for producing DVDs! Comments, suggestions appreciated. While I wait I'm compiling version 3.3.3 of Qt, so I can give qdvdauthor a try. And if that doesn't work, I guess I'll be writing XML files by hand.

That would be me :-) I'm using a recent CVS version of mjpegtools (I got tired of waiting for the followon to 1.6.2) -- 10/05/2004 to be Well, I have attempted to set the wheels in motion for a release but so far haven't heard too much back about getting a release cycle started. precise. It's also a pretty recent version of DVD Studio Pro (Academic version), version 3.0.1. But really, I haven't Great - that's what I was using last night - created a couple DVDs and started on the third one (then couldn't decide was style I wanted to use and put it off till another night ;)). had much luck with any of the Apple software reading mpeg-2 files created with the mjpegtools. Hmmm, was this with the CVS version or before you upgraded from 1.6.2 to the CVS version? The default version of Apple Quicktime won't even recognize mpeg-2 files at all. Fortunately, the Production Suite of tools that I purchased with my came with an upgrade to QuickTime Pro. Yeah - Apple deserves a demerit or two for _that_. The MPEG-2 playback module's a $20 upgrade to a free player. Then if you want to _encode_ it's another $30. So the free player program isn't very useful until you upgrade the heck out of it. AND EVEN THEN it balks at DPME (Dual Prime Motion Estimation) (and so does DVD Player). Seems someone at Apple didn't read deep enough into the MPEG-2 specs... AND that is one of the reasons I changed the default in mpeg2enc to be no-dualprime (the other reason is that there's a bug that can generate whiteblock artifacts ;)). Oh - you bought the Production Suite also? Took me a few hours to install the ~24-30GB - now to start reading the manuals :-) Unfotunately however, while QT-Pro would recognize and read the files it is not able to handle them at a respectible rate -- after the first few moments of one file I created the frame rate of displaying the video drops to between 2 and 7Hz. This is for just playing? You're not trying to encode - correct? When/how was the file generated? If it was generated using 1.6.2 then you're likely getting hit by the DPME bug. Whereas a version of mplayer that I downloaded for my Powerbook plays the file just fine. I build my own MPlayer (and ffmpeg, etc) but yes, the quartz video module(s) in MPlayer do a good job. I should say that my Powerbook is a brand new 15 w/ Super Drive, and a 1.5GHz G4 processor. Also, the files I'm trying to play Lucky you - I got my Powerbook back when 1GHz G4 was the state of the art (but the 17 screen's nice ;)). come from two sources -- a Canopus 100 capture via dvgrab, and using smilutils to feed into an mpeg2enc pipe and then multiplexed with the mjpegtoosl multiplexer -- at bitrates within the DVD specs. Ah - yep sounds like your workflow is similar to mine. All except for the last part. DON'T multiplex the files together! DVDSP wants the elementary file - the .m2v file! The other source is an IVTV capture from a Hauppauge PVR-350. In that case, the capture was at bitrates above DVD spec, so I use mpeg2dec to decode them, piped through pgmtoy4m, filtered, and then reencoded with the mjpegtools mpeg2enc program, and again mplexed. Identical to what I do - except for the mplex step.Nice to hear that the pgmtoy4m program is being used by folks other than myself! I do a similar recoding with the HDTV broadcasts I capture over the IEEE1394 bus with 'DVHS' (it's one of the demo/test apps in the Firewire SDK you can download). Don't mplex the files - leave them as elementary stream files. Oh, I use avidemux2 on the latter to trim the beginning and end of the TV capture, and then save the files as Audio and a separate Raw video stream. Oh you can do all the trimming, etc right in DVDSP - that's how I adjust the beginning and ends of a track. Enter DVD Studio Pro. When I try to import the asset of one of these multiplexed mpeg-2 video files, I get a popup that tells me: Alert: Import Assets Could not import one file. Incompatible Format ARGH! And that's the problem. DVDSP wants
