LinHES Forums :: View topic - R5E50: Nuvexport

grg: that link was listed in the original post in this thread. i'm pretty sure they were looking for clarification...

being a late adopter to r5e50, i'm having a similar problem to yours about a compilation error, but on a different line and it doesn't seem to be syntax stuff...

Code:

Compilation failed in require at /usr/local/bin/nuvexport line 37.
BEGIN failed--compilation aborted at /usr/local/bin/nuvexport line 37.

i've taken a look at line 37 (after following the nuvexport update instructions from cecils post) and it shows

Code:

# Load the myth and nuv utilities, and connect to the database
    use nuv_export::shared_utils;
    use nuv_export::cli;   <-- line 37
    use nuv_export::ui;
    use mythtv::recordings;

anyone have any ideas on what might be wrong or where i might turn?

I love my KnoppMyth mbe and sbe systems and I've often used nuvexport --transcode to convert stuff I want to keep into .avi's. I've been very happy with this until it broke in R5D1 and is still a problem in R5E50. cecil posted what he hoped would be the fix for R5E50 here: http://mysettopbox.tv/phpBB2/viewtopic.php?p=79265 but it doesn't work for me or for several other users. IEnigmusI followed up with a post that attempted to clarify, but unfortunately only confused matters more. There have been several questions posted there since, but no one is responding to that thread anymore. Therefore, I was wondering if someone could post the clarified fix if there is one, or if not, please post that nuvexport is broken. The error I get is: syntax error in /usr/share/local/nuvexport/export/transcode/SVCD.PM line 176 near "." Compilation failed in require at /usr/local/bin/nuvexport line 51 Thanks for your time.

I also miss having nuvexport. I have tried the new latest version (jan 13) and it appears to exhibit the same problems. As far as I can tell from scanning the myth mailing list and trial and error, there are two basic problems at the moment. The current version does not set the bitrate properly for the dafault decoder (ffmpeg) and this is what leads to the terrible quality of the encoded files. There is a syntax problem with the script that sets up encoding with transcode, so that is not an option at the moment either. I am hoping that the solutions to these problems will be forthcoming for those of us who are not able to ferret the answer out on our own!

I worked around this by editing /usr/local/bin/nuvexport and removing 4 lines. Around line 55 Code: require export::transcode::SVCD; require export::transcode::VCD; and around line 85 Code: push @Exporters, export::transcode::SVCD->new; push @Exporters, export::transcode::VCD->new; Commenting out these lines should work as well. These edits disable exporting to SVCD and VCD, but my primary use is XviD so no big deal for me.

Thank you very much! It worked for me as advertised.

Thanks for the workaround for transcode! Now I can get acceptable quality using xvid. It would be great if someone could figure out the ffmpeg problem. I have tried two new versions of nuvexport plus svn as well. All of them give terrible quality with ffmpeg. It must be something to do with bitrate, but it is beyond me. I am sure that it will all be ironed out eventually!

I don't know if this is a related problem, but when I was testing trying to export some .nuv files using MythArchive, the framerate value passed to ffmpeg was 0.04 rather than 25 (this being a PAL system). So causing ffmpeg to halt. Bruce S.

It appears that the common thread is ffmpeg. Doesn't it?

I'm just happy to have it working. But it is running much slower than before. 3X slower. It used to take about 4 hours to transcode a 44 minute show, but now it takes 12 to 12 1/2 hours.

They keep releasing new versions of nuvexport and they all seem to have their quirks. Unfortunately, it appears that it may not be stable until it is incorporated into the next Mythtv release. You may want to scan the MythTV message list. I often find that they have information regarding nuvexport. I have been having so much fun using Myth Archive that I haven't used nuvexport much lately.

Post subject:	Possible fix
I had a similar error when I was installing myth2ipod yesterday and I fixed it using the modification found here: http://mysettopbox.tv/phpBB2/viewtopic.php?t=10678 by chris_s on March 5th (third page, bottom) Hope this works for you drutherford
