[mythtv-users] H264 and Nupplevideo transcoding

[Steve Briggs]

A couple of questions:


1) It seems Nupplevideo is on the way out.  My latest myth update
(0.25.6) seems to have introduced some flakiness in recording from
a Hauppage Win-TV and also in transcoding for commerical removal.
(during playback, recordings just end abruptly, with no idication
that it's really at the end of the file.)  I'm thinking I need to
transcode my .nuv recordings (over 4000 SD) to something else while
I still can.
I'm thinking the best approach is to use ffmpeg to convert to
H264.  This would involve changing the .nuv file extension to
.mp4 or .mkv.  I know the filename shows up in many of the database
tables.  Do I need to do anything besides go through the database
and change the filename in all the tables?


2) I have a HD-PVR, and it makes great recordings, but mythtranscode
doesn't seem to be able to cut commercials out (and I tend to
not use it because of that limitation).  I've seen old (2009-ish)
threads on doing this outside of myth, but it seems like this was
dropped with a "we're working on a better way to do this."  But,
I haven't seen much on the better way.

What's the status on this?  When I try to just transcode for
commercial removal like I would with a Nupplevideo, it fails
with a "Couldn't find profile for : H.264", and I was unable
to create such a profile.

I've really been happy with mythtv for the past 7 years, and I'd
like to be able to do this within myth, rather than some
convoluted export, reencode, cut, import.... etc.


3) BTW... my old Comcast DCTXXXX box died and they gave me
a new RNG110. Channel changing works fine via firewire with
6200ch.  I can stream raw video from firewire and watch it with
mplayer, but mythtv doesn't record properly.
This is OK.... as I'd rather use the HD-PVR.


TIA
