Any tips for batch BitStream Upacking & Identifing?

[pongo]

Hi All,

Does anyone have a tips for software that can batch unpack bitstreams from XviD files so they can be played back without ‘jerky’ picture problems on my DVD-339 DivX / DVD player?
Or another ways to get round this problem easily, that seems to affect standalone .avi hardware players?

Also, it there any good programs or ways to identify files with packed bitsreams easily?

I want to make DVD-/+R collections of many .avi files on DVD without having to recode my files into DVDs.

I've just purchachsed a DK Digital DVD 339 DivX / DVD player from eBuyer UK and I’m very pleased with it and its play back of DivX and XviD files, and it does play back files on DVD+R/RWs as apposed to its instruction manual!

Any tips would be greatly appreciated and save me a lot of time!

I am currently using MPEG4 Modifier, which works very well on single files, but is very time consuming when it comes to converting many files.

Thanks VideoHelp, your site is untouchable for helping Newbie’s like me to get round video problems on my PC!

Use UnpackCL from the same author. If a file isn't packed, it will just scan it, if a file is packed it will unpack after scanning.

Hi Celtic Druid,

Thanks for that! I've downloaded UnpackCL from the authors site, but I am not sure how I actaully go about putting in the commands to unpack the bitsreams!
What should I put in the command kline to open say C:docs and settings>me>my docs>my videos

Also does it automatically change the file names and save them in the same folder or in another foldetr elswhere?

Thanks again for your help!

Simply run for options:

UnpackCL v1.1.0 by Moitah
Based on MPEG4 Modifier v1.3.2
http://www.moitah.net/

Arguments: [switches] source_path [dest_path]
Switches:
-i Displays detailed information about the video

To unpack in C:docs and settings>me>my docs>my videos
unpackcl "c:\documents and settings\me\my docs\myvideos\whatever.avi" p:ath\to\output.avi

or get creative:
for %%f in (*.avi) DO (UnpackCL.exe "%%f" "%%~nf.up.avi")

create a mirror path on d:
for /R %%f in (*.avi) DO (mkdir "d:%%~pf")
for /R %%f in (*.avi) DO ((UnpackCL.exe "%%f" "d:%%~pf%%~nf.avi")

etc.

Thank again Celtic Druid, sorry to be a pain, but please consider me a total newbie when it comes to using Command Prompt!

I'm having 2 problems -
1. Every time I open unpackCL.exe it immediatly closes!
2. I've tried entering the code you mentioned but I am unsure if I have to change parts of it to be relavant to my folder structure.

To make it clearer for me, I have made the following folders - a packed bitstrwam source folder and a unpacked output destination folder.

If you would be so kind as to litterally tell me exactly what to enter I would be very grateful! One day, I hope to be the one dishing out advice, thanks for your patience!

Source Folder - I:\source
Output - I:\output

Finally, the location of unpackCL.exe on my PC - C:\Documents and Settings\pongo

Thanks again!

start -> run ->cmd , hit enter

you will have a command window

drag UnpackCL into the command window so you dont have to type the path each time (or put UnpackCL in your path (like root of C:))

I kinda assumed that you had some knowledge since you asked for a batch app.

With the for.... commands you can simply save as a batch file and run in any folder. It will process all avi files therein. With /R it will also do sub folders.

i:
cd\source
for %%f in (*.avi) DO ("C:\Documents and Settings\pongo\UnpackCL.exe" "%%f" "i:\output\%%~nf.avi")
Should do it.

Setting the output path to a different physical drive should result in a speed boost though.

Thanks both!
I looked up how to make a batch file in google and entered the text from Celtic Druid, beginning FOR, saved the batch files and ran it inside one of my folders and bingo! It Worked!

Thanks for all your help!
