OK I solved it after reading the FFMpeg documentation
....
It turns out in the iPod.pm file the audio bitrate is in kbps but the video is bps... Putting in 780000 instead of 780 yields the correct file size.
I finally realized that myth2ipod is calling nuvexport and it is loading ffmpeg settings from iPod.pm.... I tracked down the ffmpeg documentation and realized my problem....
The other option is to add nuvoptions in the myth2ipod file for the audio and video bitrates....
I kept getting 50 Mb file size files for a half hour show and that was with a video bitrate of 768 (Should have been 768000)
Reference;
http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC8
`-b bitrate'
Set the video bitrate in bit/s (default = 200 kb/s)
http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC10
`-ab bitrate'
Set the audio bitrate in kbit/s (default = 64).
Code:
# Load default settings
sub load_defaults {
my $self = shift;
# Load the parent module's settings
$self->SUPER::load_defaults();
# Default bitrates
# Original Settings
# $self->{'defaults'}{'v_bitrate'} = 384;
# $self->{'defaults'}{'a_bitrate'} = 64;
# Modified Settings for Enhanced Quality
$self->{'defaults'}{'v_bitrate'} = 768000;
$self->{'defaults'}{'a_bitrate'} = 128;
}
sub load_defaults {
my $self = shift;
# Load the parent module's settings
$self->SUPER::load_defaults();
# Default bitrates
# Original Settings
# $self->{'defaults'}{'v_bitrate'} = 384;
# $self->{'defaults'}{'a_bitrate'} = 64;
# Modified Settings for Enhanced Quality
$self->{'defaults'}{'v_bitrate'} = 768000;
$self->{'defaults'}{'a_bitrate'} = 128;
}
