I currently use a modified myth2ipod script to encode recordings for my pocket pc. The only problem is that my recordings are named with the cryptic myth numbering scheme.

Does the solution that you online in the WIKI yield files with useful filenames? i.e. is the show title in the filename?

If so, I'll give your method a try.

No does that 1002_1231341423.XviD.avi naming. But try chaning around the nuveport line to something like below.



Beware you may have problems though with shows with invalid filename charcter like "That 70's show" .

pardon my ignorance but what is the difference between doing this and selecting the autotranscode option in the setup menus and selecting autodetect from mpeg2 to transcode to mpeg4. What is the difference?


It has options to select 2 pass encoding, etc. Isn't xvid just open source mpeg4? Why not avc h.264 ?

XviD is a type of MPEG4 from my understanding XviD is high quality format with smaller file size than MPEG4. 2 pass XviD should be around 475mb compared to 900mb for MPEG4. I am not sure though on MPEG4 size though I have not tried it since R5A26 on a VL4 card. For me XviD is more of a defacto codec standard and the quality/size ratio fits my needs for archiving recorded shows.

h.264 would certainly be nice, I hear x.264 handles HD better. I just didn't take the time to reseach if/how nuvexport can export to H.264, it may be possible.

Just figured out a gotcha on the Myth2xvid script ...

Just as a background I just built a new MythBox this weekend and since I have a lot of stuff encoded to X264 I recomplied the mplayer to use X264
4th post down is the script I used for the x264

Then I followed the Wiki to add the XviD script. When I ran the job it would show that it is completed but then only thing done was the RSS feed. When I finally got down to the most basic way to transcode the clip (nuvexport) I got a division by zero error. I found the fix in this post basically I needed to add --force-aspect=1.33 to the nuvexport command. It appears that the MPlayer upgrade caused their problem so I am assuming that it also caused mine.

I changed the code like this and it seems to run now

Try nuvexport from the command line.

Either

or

Wizard will walk you though, what type of card are your recording coming from?

I have try that and it wont work. Same problem

My card is a hauppauge 150.

hmmm. does nuvexport work with any format ? asf, divx, vcd ?

You log previously shows using transcode engine. Using ffmpeg should show.

Anything out of the box/extra you did to your KM install?

Maybe try installing ffmpeg from cvs? Directions from Myth2ipod page..

http://www.myth2ipod.com/myth2ipod.html

Just change the one step around a little to enable mp3lame in ffmpeg

I can't seem to get this to work. I followed the instruction on the wiki exactly (the only exception is the location where to put the files, I used /myth/archive instead of /myth/video/archive). The job runs and finishes pretty much instantly and the new file is not there, so I tried running it from the command line using this command:



and here is the output:




Any ideas?

Follow up to my previous post, I updated to a newer version of nuvexport since I'm still running whatever version came with R5A15, and now I get the message:



So I followed the instructions on the wiki for updating ffmpeg from cvs, and after installing it still says I have the same version of ffmpeg as before, and I cannot run nuvexport anymore. Is this a problem of me running too old a version of Knoppmyth? My box has been working great for a long time so I didn't want to upgrade.

I started getting this today also. I had just updated the version of nuvexport and tried to run it. I got:




After updating to the latest cvs version of ffmpeg, I am still getting the same error.

So does this work on the nuv files? I don't want to automatically transcode all of my recordings, but it'd be nice to have a one click solution to have them ready to play on my PPC with Core Player.

I would like to use this for my HDTV recordings, but i want to try to preserve the original ac3 track, or even re-encode it at a lower bitrate. Would that be possible using this script?

Maybe? You may have to use the --transcode option rather than --ffmpeg. I have used nuvexport with recording with a vl4 software card before of R530.2, but I no longer have that card to test.

Don't know try nuvexport from command line and see if it preserves the AC3 if not look into command line switches to preserve the audio and modify the script as appropiate.

I have been out of town last few weeks, but I plan on testing this on R5D1 reading some posts could be some issues with either ffmpeg or nuvexport since R5C7.
