tablet-encode v2.18 has been released. More detail at:

http://www.maemopeople.org/index.php...uch_improved_d

To set the default preset and to always enable 770-compatibility mode, create ~/.tablet-encode.conf and put in it:

Code:
$options{770} = 1;
$defaultPreset = 'good';
You can also define your own presets, there's more info in the README.

Let me know if you have any problems.

Is it possible to add few more parameters for the tablet-encode? I tried to use "--mencoder=ARGn" but couldn't get it working.

I have some kung-fu DVDs which have English audio set as a default and when I make conversion, tablet-encode selects it. However I would like to have original Chinese audio with English subtitles.

I have also used few other parameters with my own script (based to ones found on maemo.org wiki) which I would like to see also in tablet-encode. One of those is possibility to keep original aspect ratio and still crop black borders away. Videos will be 400 pixels (or whatever is set as resolution) wide and height will be automatically calculated based on aspect ratio. At least mplayer plays these videos correctly and black borders aren't encoded at all.

These are the mencoder parameters I would like to see in tablet-encode:

#Audio language e.g "zh"
-alang <lang code>

#Subtitle language e.g "en"
-slang <lang code>

#Subtitle font and its size
-subfont-text-scale 7 -spuaa 3 -subcp latin1

#Crop value and scaling to correct aspect ratio.
-vf crop <x:x:x:x>,scale=400:-10

I have used "mplayer dvd://$TITLE -vf cropdetect" to get correct crop value. Crop value can be different in the start of the movie so I have selected manually a position which I would like to use as a crop value and then I have then put it as a parameter for "-vf crop".

Here is the script I have used to convert my DVDs. It's bit rough edged but it has been working just fine for me
Code:
#!/bin/bash
#
# N800dvd.sh
#
# Usage: N800dvd.sh

mve, thanks for the feedback.

* Auto-cropping using cropdetect is possible, but why've you got videos with encoded black bars in them anyway? ;-) I'll look into it for the next version.

* Original aspect ratio can be maintained with --original-aspect (-o).

* -alang is passed through for auto-detected DVDs, based on $LANG. I'll look at doing it more often.

* --mencoder=ARGn should work, e.g.:

Code:
tablet-encode -o -m-alang -mzh -m-slang -men in.avi out.avi
You can use the new ~/.tablet-encode.conf feature to use these as standard, if desired.

Hope that helps,

Andrew

Yeah, those crappy 1:2.35 DVDs why they just don't make all those in 4:3 full screen Thank you for looking it.

This was a thing I was looking. I had wrong syntax when I tried tablet-encode. Now I can hear original CHAP and CHOP sound effects in my movies with Chinese dialog and English subs

Ah, 2.35:1 DVDs. Good point :-)

Tablet-encode is awesome!

I wanted to set it up to automatically encode all the files I download with azureus... not there yet, but I ran into a bug with mencoder and mkvs that I've run into before, where it cuts short mkv files while encoding randomly. My point is, I found where someone wrote up a workaround for it, and the way you can pass any mencoder option to tablet encode via -m let me use it really easily. Thanks a ton for this great program!

(The other awesome part about tablet encode to me? I can launch a progress bar for my conversion from the command line, meaning I can automate things with visual feedback. And if I put it inside screen first, I can get remote console feedback on the progress of files, too! )

If the option is something which could always be passed for *.mkv files without any problems, let me know and I'll stick it in by default.

That'd be great! It could be passed without issue; the way I do it does add a bit of extra time (about 10 seconds on my machine) to the process up front, though. I know there are better ways to do it -- you can extract the audio first -- I just haven't bothered.

The bug can be summed up as: mencoder has trouble with mkvs when it has to also decode the audio for some reason; I know nothing of the technical details. The workaround I use is a bash script; I thought about modifying tablet-encode, but I know almsot no perl.

Problem with how I do it is, what if you are not on a Linux system? I don't know if other systems work the same way or how to adapt it.

Here's what I do, without the stuff specific to me:
Code:
#!/bin/bash
        TEMPFILE=`mktemp`
        rm $TEMPFILE
        mplayer "$1" -ao pcm:fast:file=$TEMPFILE -vc null -vo null
        ~/bin/tablet-encode --preset mplayer -m-audiofile -m$TEMPFILE --gui $1 $2
        rm $TEMPFILE

I can't seem to get the syntax of this file down. Could you post an example, converting the code above into the .tablet-encode.conf format as a further example?

No problem at all! At the moment, it might require a little too much Perl knowledge, I'm hoping to drum up some extra developers at the Maemo Summit lightning session on tablet-encode.

For the above command line options, put this in ~/.tablet-encode.conf:

Code:
$options{'original-aspect'} = 1;
$options{'mencoder'} = [qw(-alang zh -slang en)];
The next version of the GUI (some thoughts based on suggestions from RST38h here) should provide a mechanism for maintaining the configuration file to make it easier to set your default options. Again, patches and suggestions always welcome :-)

Hope that helps,

Andrew
