Re: [mythtv-users] nuvexport errors doing DVD export
So, using '--transcode' the thing transcode was going to take 3 lifetimes to complete, so I took the fact that the power cut halfway through as a sign that I should do this using the apparently much faster ffmpeg. So I got the latest source from ffmpeg cvs, and compiled and installed OK. Now running nuvexport in --ffmpeg mode, I can select XviD (w00t) and all the options seem to be OK, accepting the defaults. It says its waiting for mythtranscode and then starting ffmpeg, and after a wee while it crashes with the nasty pipe error. So I debugged and modified the ffmpeg forked line to remove the yuvdenoise filter and it went through, taking about an hour to transcode the 40 minutes DVB-T video down to 320x240 XviD which I was happy with performance wise. The problem is, the video is not playable though the sound is OK both WindowsMedia and MediaPlayerClassic both complain. I put this down to the fact that I possibly mistimed the starting of ffmpeg given I was doing this from --debug mode. I have since started the transcode using nuvexport, deselecting denoise and deinterlace as I selected the options and now, the transcode is going to take about 3 hours, even though it is running at 20 fps (isn't Mpeg2 only 25fps?). So, to my question. How can I get reasonable good and fast transcoding? Is ffmpeg faster? Given I am planning on watching these on the PocketPC only I may aswell turn of deinterlacing and noise reduction right? Should I leave the recording at the native resolution and let the PDA struggle or is it right to downsize? Any help is *greatly* apreciated.

Re: [mythtv-users] nuvexport errors doing DVD export
Heh, I hope someone is following this threadChris??? :P So I chose to nuvexport to DivX last night usin g--ffmpeg and it was really quite quick, 30 mins for a 40 minute MPEG2, including the downsizing, though I turned of noise reduction etc. The problem is, I am running the latest version of ffmpeg and it seems to have used data partitioning in the encoding of the DivX video and that is NOT supported by BetaPlayer (or The Core Pocket Media Player as it is now called). I can see you can enable or disable this from the command line using '-part' option in ffmpeg, but I wonder how I can do this from nuvexport. Given my plan is to use nuvexport as a UserJob, I can't see how to prevent ffmpeg from doing that by default. Any ideasplease =D Whytey On 7/15/05, David Whyte [EMAIL PROTECTED] wrote: So, using '--transcode' the thing transcode was going to take 3 lifetimes to complete, so I took the fact that the power cut halfway through as a sign that I should do this using the apparently much faster ffmpeg.

Re: [mythtv-users] nuvexport errors doing DVD export
I have tried searching the mailing list, but please remember, sometimes it is hard to find an answer, unless you already have an idea what solution might be. searching for pipe:: Error while opening file (the error message I just deleted off of a your quoted message because it was too far back to include here) comes up with a bunch of stuff: http://www.gossamer-threads.com/lists/engine?list=mythtvdo=search_resultssearch_forum=allsearch_string=pipe%3A%3A+Error+while+opening+filesearch_type=AND generally, a search on the exact error message (try putting quotes around it if just pasting the text in doesn't turn up results) will at least give you something. What do I do? Search for nuvexport DVD error? Not much turns up. That's why people like myself end up asking the question again, even if it means someone has to tell us what search terms will trigger the elusive result from basic search engines. Yes, but I don't know the difference between those who have searched and those who haven't unless they say something like searched, couldn't find anything. -Chris ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
