Here is a WIKI howto with needed config file on configuring KnoppMyth to automatically encode recordings to XviD format using a modifed myth2ipod script. http://www.knoppmythwiki.org/index.php? ... iDEncoding |

Seems to work fine, but takes an unbelievably long time to encode... I'm currently encoding a 42 minute recording... I started at a little after noon, and now it's almost 7:00 pm and still encoding. It doesn't seem as though my hardware should struggle this much with XviD, even two-pass conversion. |

Try changing the encoding options in myth2xvid (line 19) to below. Code: my $nuvoptions ="--mode=XviD --nice=19 --cutlist --nodenoise --deinterlace --crop --multipass";
(updated WIKI to reflect --nodenoise option) I don't have the origianl machine I used to create the guide available, I used so many options I may have documented the wrong one. Changing the mentioned denoise reduced the time for a 1 min recording from 35 minutes down to 11 on my PIII 500, |

My encoded file will not play on windows. I get audio but no video. I am using Media Player Classic. It complains that there is not a needed codec or filter. Does anyone know how to fix this?

You have the XviD codec installed? http://www.koepi.org/XviD-1.1.0-30122005.exe Or something like the "K-Lite Codec Pack" will let you play most formats including XviD. |

Yes, I installed the latest Xvid codec. Are you able to play the file in Windows? |

I'm experiencing the same issue as esurfer. XviD is installed, other XviD files play without issue, but encoded shows play audio without video. I've tried Media Player Classic and Windows Media Player. |

I downloaded and installed the Full K-Lite Codec Pack. That fixed my problem. The audio levels are really low though. How do I transcode so that the audio levels are higher? Thanks for you contribution! esurfer |

Hmm, Glad you got it playing but just the core XviD codecs should work if is encoded in XviD. I am going to have to play with some Windows boxes to see if can figure that out. Not sure on the audio levels, from what I researched ffmpeg encoding volume is set by source recording. What tuner card are you recording from? |

I too had problems playing recordings in WMP. A better fix was to install VLC (www.videolan.org). It is much more customizable than WMP, especially in using keys for various functions. |

Great guide. Thanks. I corrected a couple of typos on the wiki that were referencing the old ipod information. Hope it's okay. ________ SATIVA STRAINS |

I have recreated the problem with no video only audio as discussed on this thread using an XP PC with just XviD codecs installed. Other XviD encoded vidoes that were created using the DVD import function play fine. It appears something is getting written using an additional codec using myth2xvid, I tried chaning interlace/denoise/resolution/crop setting with no effect. Next step is to mess with trying the transcode options rather than using default ffmpeg. |

Ok, Got this issue figured out. Apparently something in ffmpeg when using nuvexport is creating a video with non standard XviD codec. I changed the nuvexport command line to Code: my $nuvoptions ="--transcode --mode=XviD --nice=19 --cutlist --nodenoise --nodeinterlace --crop --multipass";
The resulting video is now playable on a Windows PC with only XviD codecs installed. From what I read the transcode option tells nuvexport to use transcode engine over the default of ffmpeg. 2 Good resources on Nuvexport, encoding time, and size quality differences in formats. http://www.inaudible.co.uk/nuvexport/in ... tNuvexport http://www.linuxjournal.com/article/8524 The time for me is increased using --transcode to 10 min versus 7 min using ffmpeg on a PIII 700 for 1min clip. Considering if I should change the howto around to utilize –transcode option. If using transcode can eliminated steps 1-9 to update ffmpeg, resulting video is playable using standard XviD codec, but is slower to encode. (1 above link mentions hack for dual core chips that could speed up) Currently will average 5 hours for 30min video on my PIII 700. If continue to use ffmpeg resulting video requires “extra” codecs or VLC player but is faster to encode. Currently will average 3.5 hours for 30min video on my PIII 700. I also changed the –nodeinterlace line, according to above resources doesn’t overly help on SD recording. |
