[mythtv-users] new video2ipod script released!

Fri Mar 7 11:48:49 UTC 2008

Going to test 0.7 out now. 
I just finished encoding with 0.6 and it didn't work that great.. 
The I encoded an HD (720p) show. The show was 1 hour 9 mins and 55 seconds
long.
The video conversion processed fine and it even stayed in the 16:9 format.
It is the audio that is screwy.
At the beginning the audio seems fine althou it is out of sync by a few
milliseconds. That's fine, I can work with that.
At 28 mins 22 seconds the audio suddenly it starts going double time, or
faster, and it sounds like I'm watching an old chipmunks show. But it is way
too fast to actually pick out the words. And, due to the faster audio, the
audio stream stops at 42 mins 12 seconds.
Through all of this the video came out crystal clear. If we can figure out
this audio issue this script will be sweet.

The command I used is as follows:
video2ipod.pl -force16 -threads 2 -myth -tvdotcom -chanid 2825 -starttime
20080304205500 -log /tmp/video2ipod.log -type h264 -verbose -debug -output
/record/working

I'm not sure how fully tested the multiple threads option is, so on my new
test I'll go back to 1 thread.

Well this isn't good.
Here is s step by step.

Download 0.7 and attempt to run with -version it fails telling me I do not
meet the new Text::Template dependency. So I had to install the
Text::Template module for Perl. Not an issue.
Run version again and get results.
niflheim ~ # ./video2ipod.pl -version
video2ipod.pl 0.07

So I go straight for the big one. I removed -threads 2 cause I thought that
might be the issue with audio and I added -cutcommercials cause that's the
new toy.
niflheim ~ # ./video2ipod.pl -cutcommercials -force16 -myth -tvdotcom
-chanid 2825 -starttime 20080304205500  -log /tmp/video2ipod.log -type h264
-verbose -debug -output /record/working
video2ipod.pl: Logging to /tmp/video2ipod.log

Almost instantly I'm back to hash.

Here is the log.

/tmp/video2ipod.pl-75V0_/tmpODjkl.mpg: Unknown format

I take a look at /tmp/video2ipod.pl-75V0_ to see what is there.. and it does
not exist.
I'm thinking either the new code is bad, or there is another dependency that
is not checked for and I do not have it.
