mkisofs: No such file?

[batman2]

I have an AVI (in PAL format) that I converted to an NTSC MPEG-2 using tmpgenc.

I open this with ffmpegx, choose the 'DVD (mpeg2enc)' Preset (also deselect 'encode with Quicktim' and choose 'set 3:2' and press 'encode'

It runs and runs, then stops with a red 'failed' notation on the little progress window and the last few lines of log are below.

INFO: dvdauthor creating table of contents
scanning /Users/Movies/the.movie.mpg.ff.mpg.DVD/VIDEO_TS/VTS_01_0.IFO
/Applications/ffmpegX/ffmpegX.app//Contents/Resources/mkisofs: No such file or directory. Invalid node - /Users/Movies/the.movie.mpg.ff.mpg.DVD

I get a .DVD folder with files that look to be the right size, but I do NOT get a .img file. When I try to 'Toast' the Video_TS folder to a blank DVD I get video and audio that are off-synch by several seconds.

What is this mkisofs I seem to be missing?

Thanks,

If you already converted an AVI to MPEG-2, there is no need of using the DVD mpeg2enc preset, as it will convert MPEG-2 to MPEG-2 again.

If you want to author your MPEG-2 as a DVD, you should open the .MPG file in the Tools tab, enable the "Author as DVD" checkbox, and click the "Author" button.

Also, put the ffmpegX application at the first level of the Applications folder and not inside another folder.

Specs on the file are these: VIDEO: mpeg-2, size: 720x480, 29.970 fps, 4500 kbps. AUDIO: mp2, 48000Hz, 384 kbps

As a test, I open it with mplayer and it plays perfectly.

Then, twice in a row, the following occurs.

Using the 'Tools' tab, I open the file with the top 'browse' button, select 'Author as DVD', and 'press the 'author' button, it grinds away for a few minutes, a .DVD folder appears with a Video_TS and Audio_TS folder within. Files named 'VTS_01_0.IFO' and 'VTS_01_1.VOB' soon appear. Both are at 0 KB when the 'application unexpectedly quits'. The first few lines of the 'crash report' are:

(there are, like, another 150 lines following this).

There is 12 GB of space available on the hard drive.
Any ideas?

I don't know whether this is a clue or not.
I made a third attempt, just as described above, except this time unchecked the 'keep elementary streams' box.
This time it ended without crashing, and created the same folder/files
I described above, with both files still 0 KB

I have an AVI (in PAL format) that I converted to an NTSC MPEG-2 using tmpgenc.

Could be the problem.
I just tried it using files created by ffmpegX. Worked great, right down to mounting the image and playing it with Apple's DVD Player. You might try demuxing the mpg, entering the m2v & mp2 into the tools tab, selecting 'Mux as DVD', selecting the 'Author as DVD', and then hitting 'Mux as'. That way, it will be passed to the Progress App and you can look at the Information window for errors.
Good Luck.

Man! You stole my punchline.
I was stumped, and staring at ffmpegx (like y'do) and noticed there were tabs to demux and (re)-mux. So, I thought, "This can't possibly work, can it?" But I demuxed and remuxed, and Presto!

It's the logic that bugs me. The same file, it won't hardly even begin to 'author' straight to DVD, but it will demux and remux to DVD.
I fail to get it.

Thanks for the help, though, much appreciated

uh huh.
Been there, done that.
Click on the tmpgenc link and read the last comment posted, note the Author. I wasn't kidding :P
and, I'm not the only one.....

Also, put the ffmpegX application at the first level of the Applications folder and not inside another folder.

I've had ffmpegX in a sub-folder of "Applications" for quite some time now, with no apparent ill effects. The sub-folder has no spaces or odd characters in its name. Would I benefit from moving it to the "Applications" folder, or is this to avoid spaces, etc. in the path?

Probably your .mpg file missed DVD program stream NAV packets. Remuxing added them.

[batman2]

Ah! those pesky NAV packets, of course!

Is there any way to CHECK for NAV packets and thus go straight to demus/remux instead of trying the 'author' route?
That would reduce my coaster count, and save time too.

Thanks

[major]

A stream without NAV packets won't author, so you can't make a coaster with it.

I am also having difficulties with getting an .img file. I've tried all the various combinations, including de- and re-muxing a file, then authoring. I get a *.dvd folder, with AUDIO_TS and VIDEO_TS, but no .img file.
