mythtv built-in "transcode to NUV" mechanism with nuvexport. Does anyone know if its possible? Its just the initial show selection which is hard to automate.<br><br>-devsk<br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: David Fishburn <fishburn@ianywhere.com><br>To: Discussion about mythtv <mythtv-users@mythtv.org><br>Sent: Saturday, January 6, 2007 6:00:20 PM<br>Subject: Re: [mythtv-users] nuvexport created xvid files play fine on PC buthave stutter and audio delay on TV<br><br><div> <br><br>> -----Original Message-----<br>> From: mythtv-users-bounces@mythtv.org <br>> [mailto:mythtv-users-bounces@mythtv.org] On Behalf Of devsk<br>> Sent: Saturday, January 06, 2007 6:57 PM<br>> To: Discussion about mythtv<br>> Subject: Re: [mythtv-users] nuvexport created xvid files play <br>> fine on PC buthave stutter and audio delay on TV<br>> <br>> answering my own
question. I found that ffmpeg creates a more <br>> compliant avi compared to transcode, and fixed all my <br>> problems with sync and fast forward. I recently did a <br>> comparison of ffmpeg and transcode from nuvexport with the <br>> same settings. I found ffmpeg to be a winner in all aspects: <br>> quality, speed, compatibility and size closer to the <br>> specified bitrate. I have uploaded two frame grabs for <br>> comparison purposes<br>> <br>> <a target="_blank" href="http://home.comcast.net/%7Efuntoos/transcode.png">http://home.comcast.net/~funtoos/transcode.png</a> <br>> <<a target="_blank" href="http://home.comcast.net/%7Efuntoos/transcode.png">http://home.comcast.net/%7Efuntoos/transcode.png</a>><br>> <a target="_blank" href="http://home.comcast.net/%7Efuntoos/ffmpeg.png">http://home.comcast.net/~funtoos/ffmpeg.png</a> <br>> <<a target="_blank"
href="http://home.comcast.net/%7Efuntoos/ffmpeg.png">http://home.comcast.net/%7Efuntoos/ffmpeg.png</a>> <br>> <br>> transcode is a little more smoothed out: note the sharpness <br>> in curtain and sunlight falling on the door thru the curtain <br>> in ffmpeg on the left side of the grab, whereas they are so <br>> fuzzy in transcode. The avg. rate was 1471 for transcode and <br>> 1508 for ffmpeg, for a specified rate of 1500. mencoder went <br>> crazy with bitrates (used 2800 for a specified rate or 1500), <br>> so was ruled out.<br><br><br>Can you show us the exact command lines you used to run<br>ffmpeg/nuvexport/mencoder. I am just now beginnning to explore the various<br>options for transcoding recording to save space.<br><br>Thanks,<br>Dave<br><br>_______________________________________________<br>mythtv-users mailing list<br>mythtv-users@mythtv.org<br><a target="_blank"
