Post subject:  Copy to USB HD?
I have a 1.5GB thumb drive that I would like to use to copy the recorded shows onto to transfer to my computer. I do not have a stable internet connection, I am using a little Linksys 802.11B Wifi bridge and it looses the connection all the time, so transferring the files across the network is a no go, I get the "Network name is no longer available" when trying to transfer even the smallest file. Would it be possible for me to set up a menu where I can select a movie to transfer to my thumb drive?




Thnx, Protoss

Of course it is possible.

Where would I start? Would I be able to modify a current function to do this?

I knew your next question would be something like that... The answer is where do you want to start? You could probably use a script (PERL, Python, etc.) or write a C++ program. As the source is open, it really is up to you.

Post subject:  Advantages of nuvexport....
There are a couple of advantages you end up with by using nuvexport.

First you can almost always cut out comercials, or bits that you are not interested in. You may only be interested in 30 seconds of that four hour program. Elect to 'watch' the show first. Use the 'E' key to edit the show, Possibly use the 'Z' key to import the detected comercial breaks. Work around those breaks to set the correct cut points from your perspective. When done 'E' to exit the edit, and escape out of watching the program. (Or do what I do, set the current position to be after the last cut out point and let the viewer exit for you.)

Now use nuvexport to convert the video to the video format you want. I usually run this in my Video folder (/myth/video) where I can then import the file into my videos menu, but you may want to use the /home/mythtv folder. I do not recomend outputting directly to the usb key for a number of reasons, the biggest reason being you should write the entire file as one copy action, not by using the usbkey as a destination for tens or hundreds of thousands of write operations in an export. The other reason is that you may find that a video does not compress down to a 1.5 gig file for one reason or another, and you can then decide if you want to edit out more comercials, or try a different format.

If you want to eliminate 'half' of the video, without loosing all the cut points, simply edit the cut points and 'flip' the direction of the points of half of the points in the part you don't want, so that they don't close the cut, but open a new cut. Then when you have exported the first half, go back and reverse those cuts to allow that portion back in, and flip the cuts in the first half to hide that half for your next export.

One additional reason to use nuvexport is that the output will be a readable file name in the form 'Show Title - Episode Title.ext'. Granted you can do the same with manual scripts of your own, but it doesn't hurt to have it done for you right out of the box.

The non-obvious rationale behind this is that flash memory is not nearly as robust as "spinning" drives, and you can wear it out.

Hi Protoss,

To answer the basic first question, it is rather an easy task. I am assuming your system is ide not sata.

as root

# mkdir /stick # or call it what ever you desire
# chown mythtv:mythtv /stick
watch out for line wrap on this one... be sure to use two >>
# echo "/dev/sda1 /stick vfat defaults,user,noauto,showexec,umask=022 0 0" >> /etc/fstab
plug in your memory stick, and wait for a few seconds. I use the upper usb port normally
# mount /stick and a prompt should return. If an error try the other port.

usr mythtv can copy / retrieve material from the stick.. a safe place for your tweaks,,

I haven't tried however you should be able to cp /myth/pretty/filename.mpg /stick with no issue. Works better than a floppy as it can be a longer recording :)
When done, # umount /stick and remove

Mike

Can nuvexport be used non-interactively? I've experimented with it briefly and it seems really useful, but what would really make it great would be the ability to call it as a userjob automatically after recording a show so that your exported file is right there waiting for you when you want it.

Relatedly:
(1) Where can I find documentation for nuvexport? I've checked the semi-official nuvexport website, and there isn't much there.
(2) What variables are made available to to userjobs? This seems necessary so that the job would know what file to work on. Is this documented somehwere?

Thanks!
