| Post subject: | R5A26 Nuvexport Fails |
I have a file recorded by a pvr 150, wanting to encode it into divx or xvid and xvid is disabled, and divx fails. It sits at 0% and waits and the says its compelted but its way to quick, like 4 mins. There is no file produced. If you trasncode a file with the gui, what do you need to play it on a windows box, because changing the extension does not work like when its in mpeg2. |

Exactly my question too. I'm experiencing the same problem. I have a fresh R5A26 install and when I try to run nuvexport-xvid it tells me that: Code: ffmpeg had critical errors:
Unknown video codec 'xvid' With divx it's similar, it tells me that ffmpeg also had critical errors. libxvid4 is installed on the box. Somewhere I read that ffmpeg needs to be compiled with xvid enabled or some-such. So far everything else on this mythbox has worked very well so I was thinking this should too. I've searched google and the forums but the above post is all I found. Anyone else have this problem, or better yet, a tip for a solution? TIA. |

Thanks for that... indeed it works but, whoa, 1.6fps... Is there a way to do the transcoding of a myth created nuv file elsewhere, say in windoze with virtualDub or similar? |

Ok while nuvexport --transcode works for making XviD I've tinkered a bit more with ffmpeg and, after updating to a later version (with apt-get install ffmpeg) I got the ffmpeg with xvid-enabled so when using nuvexport, I now have the option to create XviD files. However, when I tried doing so, ffmpeg still wasn't working. After debugging, I established that ffmpeg didn't like 2 command line options that were passed to it, namely: -hq and -4mv (I don't know why that is because the ffmpeg documentation has those options - maybe the newer ffmpeg (version CVS, build 3277056 built on Nov 1 2005 21:49:36) has changed in that respect!? Anyways, I went into the nuvexport scripts and found the places where -hq: /usr/local/share/nuvexport/export/ffmpeg.pm and -4mv appeared: /usr/local/share/nuvexport/export/ffmpeg/DivX.pm /usr/local/share/nuvexport/export/ffmpeg/XviD.pm commented them out and, voila, nuvexport worked and I'm getting about 5-6x the speed compared to transcode - yay. It'd be nice if someone more knowledegable would comment whether removing those options is a bad idea and why they don't work in the first place? |

i too was having the same problems cuz i compiled the latest ffmpeg from CVS and make install'ed the latest version of nuvexport the ffmpeg docs are understandably out of date with the latest CVS version # ffmpeg -hq foobar.mpg ffmpeg: unrecognized option '-hq' # ffmpeg -4mv foobar.mpg ffmpeg: unrecognized option '-4mv' i cant find any mentioned replacement for -hq so i too commented out the reference to it in ffmpeg.pm but -4mv seems to have been changed to -mv4 and it supposedly provides "four motion vector by macroblock (mpeg4)" which sounds useful but my nuvexport couldnt parse "ffmpeg -version" output so it was sending -4mv instead of -mv4 so i changed line 62 of ffmpeg.pm to read if ($data =~ m/ffmpeg\sversion\s(.+?),\s/si) { and the above regex does not have a $2 and the ffmpeg_build variable is never used so i commented out line 64 #$self->{'ffmpeg_build'} = $2; and now im transcoding with nuvexport, yay! |
