I also had blocky video when using the myth2ipod script to convert the file to work on the iPod and PocketPC.

Correcting the 'bit_rate' to 'b' in the XviD.pm worked for others using VCD's.

Quote:
I have managed to fix the bitrate problem for ffmpeg XviD export from nuvexport by editing the /usr/local/share/nuvexport/export/ffmpeg/XviD.pm file. Going on the observation that other people had about the parameters to ffmpeg being incorrect I compared what the perl script was generating and what the ffmpeg docs said. I noticed that the nuvexport script was using bit_rate as the bitrate flag when it looked like it should have been just b.

I found it also corrects the poor vidoe quality on my iPod, but you need to change the same issue in the MP4.pm file as well. The quality is now better than that of the R5C7 version.

Edit the file:
/usr/local/share/nuvexport/export/ffmpeg/MP4.pm

From:
Code:
.$self->param('bit_rate', $self->{'v_bitrate'})

To:
Code:
.$self->param('b', $self->{'v_bitrate'})

Great Job everyone and thanks for the clues.

And yeah, it's just a 1/2 hour show. I did make a typo in my original statement....it's actually 1.19 million frames, which is still way higher than your 40 thousand.


Um, 1.19mil = 1 190 000 frames x (1 second/29.97 frames) x (1 minute/60 seconds) x (1 hour/60 minutes) ~ 11.05 hours. There is something seriously wrong here.

cd nuvexport-0.4

Is it just me, or does the "export nuv and sql" option not export a proper sql file (it doesn't actually contain the sql commands)?
I think line 113 of export/NUV_SQL.pm has to change from:
Code:
$sh->execute($episode->{'channel'}, $episode->{'recstartts'})
to
Code:
$sh->execute($episode->{'channel'}, $episode->{'start_time'})

Hey, I owe you a virtual beer! That is EXACTLY what was wrong. Once it generates the proper .sql it's a snap to import, too.

Let me pay forward by answering the next obvious question, since everyone was a newbie at one point...

Once you have a good .sql file out of nuvexport, import it by running this mysql command (with the correct filename, of course):
Code:
$ mysql -u mythtv -pmythtv < 1012_20080113200000.sql


Here's an example of what the (channel)_(timestamp).sql file should look like. (It's plain text.)

Code:
$ cat *.sql
USE mythconverg;

INSERT INTO recorded (profile, findid, programid, progstart, hostname, previouslyshown, cutlist, duplicate, starttime, playgroup, editing, preserve, category, transcoded, stars, watched, description, progend, filesize, title, seriesid, recgroup, timestretch, lastmodified, commflagged, autoexpire, endtime, originalairdate, deletepending, transcoder, chanid, basename, subtitle, recpriority, recordid, bookmark) VALUES
        ('Default', '733419', 'EP009310070001', '2008-01-13 20:00:00', 'arbalest', '0', '0', '1', '2008-01-13 20:00:00', 'Default', '0', '0', 'Drama', '0', '0', '0', 'Sarah takes her son, John, to a small town in Mexico, where he befriends the man who will become his protector.', '2008-01-13 21:02:00', '3927899648', 'Terminator: The Sarah Connor Chronicles', 'EP00931007', 'Default', '1', '2008-01-13 21:02:16', '1', '1', '2008-01-13 21:02:00', '2008-01-13', '0', '0', '1012', '1012_20080113200000.nuv', 'Pilot', '0', '41', '0');

INSERT INTO oldrecorded (findid, programid, recstatus, reactivate, duplicate, starttime, endtime, category, rectype, station, chanid, description, subtitle, generic, recordid, seriesid, title) VALUES
        ('733419', 'EP009310070001', '-3', '0', '1', '2008-01-13 20:00:00', '2008-01-13 21:02:00', 'Drama', '10', 'KPTV', '1012', 'Sarah takes her son, John, to a small town in Mexico, where he befriends the man who will become his protector.', 'Pilot', '0', '41', 'EP00931007', 'Terminator: The Sarah Connor Chronicles');

INSERT INTO recordedmarkup (mark, starttime, type, chanid, offset) VALUES
        ('0', '2008-01-13 20:00:00', '-3', '1012', NULL),
        ('22079', '2008-01-13 20:00:00', '4', '1012', NULL),
        ('43216', '2008-01-13 20:00:00', '4', '1012', NULL),
        ('57179', '2008-01-13 20:00:00', '4', '1012', NULL),
        ('81003', '2008-01-13 20:00:00', '4', '1012', NULL),
        ('28152', '2008-01-13 20:00:00', '5', '1012', NULL),
        ('50208', '2008-01-13 20:00:00', '5', '1012', NULL),
        ('63915', '2008-01-13 20:00:00', '5', '1012', NULL),
        ('87521', '2008-01-13 20:00:00', '5', '1012', NULL);

INSERT INTO recordedseek (mark, starttime, type, chanid, offset) VALUES
        ('0', '2008-01-13 20:00:00', '7', '1012', '2020'),
        ('1', '2008-01-13 20:00:00', '7', '1012', '783809'),
        ('2', '2008-01-13 20:00:00', '7', '1012', '1129424'),


That last part goes on for quite a bit... the point is, if your .sql file looks anything like this, that means you've fixed the bug!

Thanks again!

I'm actually running Debian Gutsy, so this probably applies to all current versions of NUV_SQL.pm

R5F27 already has that fix, so it's just a matter of using a more recent version of the release-0-20-fixes branch. The header on the file says:
Code:
# $Date: 2006-09-04 12:06:27 -0700 (Mon, 04 Sep 2006) $
# $Revision: 272 $
# $Author: xris $
#
#  export::NUV_SQL
#  Maintained by Chris Petersen <mythtv@forevermore.net>

So the fix is over 15 months old...

Ummm, maybe the fact that over the course of the past 14 months they could have changed the locations? :shock:
