could somebody please say, at least, if i'm pursuing an impossibility? Is it possible at all to transocde vob to avi with 6-channel AC3 audio in the resultant avi? Am I barking up a tree without a cat in it? do i need to re-build tc with additional options? I will gladly read the FINE manual, if someone tosses me a link or two - i am not finding anything online or in the man pages. thanks andrew > > > > Below is my commandline. > > With the "-A" option ommitted from it, transcode proceeds and finishes > > (save for the glibc problem addressed earlier, as well as a couple of other > > issues like wrong aspect, which i'll address in a separate post) > > > > > > pass 1 : nice --19 transcode -H 10 -a 0 -c 0:00:00-0:1:30.8 -x vob \ > > -i /data/stuff/myvob/vob/001 -w 3810,50 -F mpeg4 \ > > -A -s 1.198 --a52_drc_off \ > > -N 0x2000 \ > > -E 48000,0,0 \ > > -Y 64,8,64,8 \ > > -M 2 -R 1 -y ffmpeg,null -o /dev/null \ > > --export_fps 29.97 \ > > --print_status 25 --avi_limit 9999 > > > > pass 2 : nice --19 transcode -H 10 -a 0 -c 0:00:00-0:1:30.8 -x vob \ > > -i /data/stuff/myvob/vob/001 -w 3810,50 -F mpeg4 \ > > -A -s 1.198 --a52_drc_off \ > > -N 0x2000 \ > > -E 48000,0,0 \ > > -Y 64,8,64,8 \ > > -M 2 -R 2 -y ffmpeg -o /data/stuff/myvob/avi/001/myvob-001.avi \ > > --export_fps 29.97 \ > > --print_status 25 --avi_limit 9999 > > > > -- > --
