I tried the above suggestion with night's CVS (Aug 28 11:00 p.m. EDT)
and it seems to work. Skipping and scanning work correctly.
I didn't check the elapse time before transcoding but the hour long
show claims to be 21:28 long. Its seems that something in the cvs
update may have changed the way elapse time is calculated. Its late
and I don't have time to time the length of this show but 21:28 seems
like the amount of time that would be cut out of an hour long show due
to commercials. So this calculation may be reversed. Was this
something that was in the verbose patch Issac committed earlier tonight?
The audio seems lower pitched after transcoding too. I'm using native
alsa support. Should I start a new thread for that one? Or, is it
normal? The file was transcoded with uncompressed audio @ 48000
Thanks for the quick work around, Geoff. Will CVS overwrite the
changes to NuppleVideoPlayer.cpp with the next update to it?
Have a relaxing Labor Day.
