Hi, I believe others have reported this issue so I thought I would post my findings.
I have two backends both running FC4 mythtv-0.18.1-114. I was seeing the following issues on the MBE. Transcodeing would sometimes fail. Most times with a cutlist update error other times no error at all. Commercial flagging appeared to finish, but there was no listing of a commflag. If I ran mythcommflag by hand it would occasionally segfault. The masterbackend would exit with no errors (I suspect it was segfaulting). The mythfront end would also segfault while playing back a recording or just running through the menu nothing consistant. All of this was very intermittant. I ran across a nuv to avi transcode script on the gossamer threads, mencoder failed each time on the MBE with a segfault but ran clean on the SBE. I ended up underclocking the motherboard and so far all these issues have gone away. I have been busy re-flagging the commercials and transcodeing all the recordings that have failed over the last month. It will be days before I can verify if things are stable. But so far everything looks promissing. The MB is a Abit AN7 N-force chipset, AMD 3200+ DDR400 memory. Running with the default BIOS setting. So besides being a darn good transcode script this script also makes a pretty good mythtv diagnostic. At least for me it gave a easily re-produceable failure that I could work with, and confirmation that the issue was solved when it did eventually run clean. #!/bin/sh # #TARGET="source.nuv" TARGET=$1 #OUTPUT="/data/video/new-file.avi" OUTPUT=$2 #optimal bitrate is 5.86*width*height OPTIONS="vbitrate=3000000:mbd=2:keyint=132:vqblur=1.0:cmp=2:subcmp=2:dia=2:mv0:last_pred=3" rm -f frameno.avi nice -n 19 mencoder $TARGET -vop denoise3d,lavcdeint \ -ovc lavc -lavcopts vcodec=msmpeg4v2:$OPTIONS:vpass=1 \ -oac mp3lame -lameopts cbr:br=128 \ -o $OUTPUT nice -n 19 mencoder $TARGET -vop denoise3d,lavcdeint \ -ovc lavc -lavcopts vcodec=msmpeg4v2:$OPTIONS:vpass=2 \ -oac mp3lame -lameopts cbr:br=128 \ -o $OUTPUT I dropped the FSB from 199MHZ to 166MHZ, and the above script ran clean on the MBE. Later I will need to start cranking it back up till I can find the breaking point. To the Author of the script thanks. Hope this info helps.
