Automated Cutting and Transcoding Guide Using Mencoder

[-stattik-]

Hello,
Taxicab Confessions 2001 All's Fare in Love
'Vegas' is not recognized as an internal or external command,
operable program or batch file.

It looks like the script is misreading the "&" character in the show title. I'm not sure how to alleviate that.

c:/windows/fonts/arial.ttf doesn't look like a font description, ignoring.
Cannot load font: c:/windows/fonts/arial.ttf
'304390' is not recognized as an internal or external command,
operable program or batch file.

The rest is standard mencoder and/or script output and should be ignored.

I have a few questions:

How are you using the script (postprocessing.bat, just dropping files on it,etc)?
Is this the only show that pops the extra window up?

Also, how can I add support for the iRiver H340?

I looked up the iRiver H340 and it seems to be a mp3 jukebox that doesn't play any video files? Perhaps I'm missing something. Could you provide more info please?

Hey,

I am using the script by dropping files on it for now. Eventually I hope to use it as a postprocessing.bat and/or with Dirmon. I have that extra window pop up for the first 4 videos I have tried.


Here is a link to the iRiver video player:

I used international firmware to enable it to play videos.

Great script! Thanks!

I guess I have another question also.. I have been using a screen reocrding device to capturing media on the internet that I couldnt otherwise download. I tried using the script in 2pass mode to transcode the files into something smaller I guess, and it gave the audio a "chipmunk" voice.

Here are the details of the file I was trying to transcode:

width 384 pixels
height 288 pixels
duration 0:02:07
bit rate 352 kbps
audio sample size 16 bit
Audio format PCM
Frame rate 15 frames/second
Data rate 1784kbps
Video sample size 24 bit
Video compression TSCC

I just got this info by right clicking in windows explorer on the file.

Any idea why 2pass doesnt work with these types of videos? ANy other profiles I should try?

Thanks!

* noopendml fix. Certain users were experiencing problems with encoding avi’s that were larger than 1 gig. This may fix that problem.

A little feedback on this... the noopendml does work. I hadn't run into an AVI becoming larger than 1 gb until recently, and sure enough, it wouldn't play in Realplayer, WMP or Nero. However, I re-encoded with the noopendml option and it plays back fine.

What benefit is there to the opendml encoding?

The window that appears along with the mencoder window is supposed to be there when you drop a file on it. It will close once the transcode is done.

I've seen some of the details for the iRiver transcodes. It shouldn't be too hard to put something together for it. It would probably work well with the hardware profile plus a few tweaks. The hardware profile is being reworked for the next release. Automatic directory transcoding is planned as well.

You could try setting the video_fps to 15. My guess is that it's setting it to 29.97 and that's what's causing the audio issues.

To tell you the truth I found the noopendml option while going over all the mencoder documentation. I know that opendml was a standard created for interoperability between codecs. If you encode to opendml specs, you could be assured that your file could be played back, especially in the professional scene.

From what I understand (or don't understand) RIFF chunks are limited to 1 GB. Additional RIFF chunks can be added as necessary and this is where things vary. An encode that results in an AVI file larger that 1 GB will fail to play without the noopendml option. However, I've combined two AVI files that add to over 1 GB and during the combine process I see mencoder creating the other RIFF chunk and the file plays fine. I'm not sure what mencoder does with the noopendml option set to make the files playable.

Sorry, I am so new to this. I tried this:

:: set video_fps=24000/1001
set video_fp=15

That didnt do anything at all. The script actually ended before it began.

I guess I did something wrong here?

I have been trying the script out on a lot of different files. It works great on mpg's, but I have had trouble with these files that I have made from a screen recorder. I have also had trouble with a widescreen movie that was in xvid format already. I was hoping that a re-encode would make it playable on my media player, but it changed it from widescreen to full screen.

Any help is appreciated.

Thanks!

sorry mis typed.

I got it right this time:

:: set video_fps=24000/1001
set video_fps=15

it still does the chipmunk audio!

Thanks

The script was mainly created to transcode mpg files, and to an extent avi files. I plan to add some more compatibility in a future release. I'd have to see what kind of files your screen recorder creates. Mediainfo is a good app to list the properties. If you could drop a file created by the screen grabber onto Mediainfo and paste or attach the results to a post it might help. You could do the same thing with the xvid file.
