    Opening >4G MPGs with Flask ?

    Hi- I have a problem opening files > 4G in flask (and all related progs like xmpeg and xis).

    I have to use flask because nandub/vdub won't open the mppeg files at all because of the weird mpg2 codec they use (from hauppage wintv pvr).

    The files appear to open, and it says it found 1 audio and 1 video stream, and I can play the vid or listen to the file- (but not position the slider within the movie)- it shows all the correct info at the bottom, EXCEPT it shows a file size of zero, and says the job is 1MB.

    When I start to encode, obviously, it crashes- or errors or something.

    I could split the files and join them with nandub but that is tedious, and anyway I tried it with one file and the audio sync took a dive on the 2nd half of the file.

    I am using XP with ntfs drives in case you wondered, and it is not an output problem as the output will be less than 1CD.

    I took a look at the source for flask, but couldn't work out why it wouldn't work- all the file positioning and file length variables are 64bit ints...

    Any help would be great, but I would prefer a solution that made flask work as opposed to using other progs (e.g. re-encoding the mpgs at the same bitrate with a codec nandub can open).

    Thanks in advance!

    I believe you can overcome your problem by using XMPEG and selecting "Open DML AVI" for output.

    By the way, there is nothing weird about the MPEG2 output of your card - it's simply that VirtualDub handles only .AVI and MPEG1 format files for input...

      thanks, but...

      I just tried what you suggested, even though I knew I had tried it before, and it didn't work. The reason it probably doesn't work is that opendml avi option is there to overcome avi size limits in output, not mpeg in input!

      Interesting about virtual/nandub only handling mpeg 1 input....

      Anyway, despite the fact that I thought I had tried everything, I gave VIDOMI a whirl, and, lo and behold, it appears to work.

      I may have to stop championing flask to all those nandub purists and start championing vidomi instead!

      What I would hate is if vidomi gives me better quality- e.g. its de-interlacing is better or something. Then I would have to re-encode EVERYTHING again. Not only that, but I would feel like I had to keep my original files (mpeg 2 files at about 7 gig each) incase I need to re-encode in the future!
