HOW-TO create video preview thumbnails automatically
#1
Okay, I just found out about one of these and the other one I wrote. If you have seen them before, then don't complain. They are new to me.

---------------------------------------
Creating XBMC Thumbnails Automatically
---------------------------------------

I wanted to have thumbnails for all my television episodes. (All my episodes are on my windows PC, sheared over my network.) Instead of downloading each file individually, I found a tip on the XBMC wiki page.

http://www.xboxmediacenter.com/wiki/inde...thumbnails

1. Download this file:
http://ffdshow.faireal.net/mirror/ffmpeg...ev10908.7z

2. Extract that file (Including the DLL) into your \\Windows\System32 folder.

3. Open up a command prompt window in the root folder of your television shows and then type this command

for /r %i in (*.avi) do ffmpeg -i "%i" -f mjpeg -t 0.001 -ss 5 -y "%~di%~pi%~ni.tbn"

You can replace the (*.avi) with different file formats, including mp4, divx, rmvb, ogm and rm.

This will open up your episodes, skip 5 seconds in, take a screen shot, rename it to *.tbn and then go to the next file. It will also do any sub folder.

---------------------------------------
Seeing *.tbn files in Windows Explorer
---------------------------------------

I bet that you know that you can go into a folder in Windows XP, switch to Thumbnail view, and be presented with an icon of the first screen from a movie. It works for images as well. Unfortunately, it doesn't work for *.tbn files. Until now, that is.

1. Create a new text document.

2. Paste the following block of text into it.

REGEDIT4

[HKEY_CLASSES_ROOT\.tbn\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}]
@="{3F30C968-480A-4C6C-862D-EFC0897BB84B}"

3. Rename the file so that the extension is .reg (I named mine "tbn thumbnails.reg")

4. Double-click the file and you are all set. Windows XP will now see TBN thumbnails as images and create a windows thumbnail for them. You can see them in your folders on your computer.

Well done! I'm going to have to try this out, it looks awesome!

Also, thanks for the .tbn preview in Windows.

Remember to share your thumbnails with others by uploading them to http://www.thetvdb.com

TheTVDB is the database and scraper that XBMC uses and it is wiki based.

Very nice, thank you.
I've been using Frameshots to make my thumbs, I'll give yours a go and see how it works.

No, it's still there, Calmiche linked to it in his post. I've been all over the wiki and had never come across this tip.

The command Calmiche uses
Code:
for /r %i in (*.avi) do ffmpeg -i "%i" -f mjpeg -t 0.001 -ss 5 -y "%~di%~pi%~ni.tbn"
does a recursive scan on folders. If you've got a directory called "TV Shows", you could simply navigate to that folder in a cmd window, and then run the command. It will look in all folders and sub-folders for video files matching the parameters (in this case, .avi files).

I can see how it would get irritating to do this with each new episode you download (or create, however you get them). Now that I've done the initial work, I plan on only doing it when a season is complete.

I saw the first tutorial before but I couldn't exicute it for whatever reason so I went with frameshots. I'll try it again, as far as the tbn viewer is concerned, I don't think it works in vista, can someone else confirm. I'll try it on my main XP server where I'm sure it will work...

Thanks,

Vista's registry is just a little bit different. Place the below code into a normal text file, and save as a .reg file (should have the little blue cube of blocks icon).
Code:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.tbn\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}]
@="{3F30C968-480A-4C6C-862D-EFC0897BB84B}"
This does work on Vista.

As for the screenshot creator - you have to have all 3 of the linked files in the c:\windows\system32 folder. Then, in a cmd window, navigate to the folder with your tv shows (ie, type in: cd d:\tv shows) and then you can use the command he mentioned. If you copied it off of the post, you can right-click and choose "paste" to paste the text into the cmd window (you can't use ctrl+v).

I added an 'if exist' to the batch file so it can run scheduled for automatic run every day.

Does anybody know how to nest the for loop so I can check several root folders in one line?

I now use:

Code:
@echo off

setlocal
set FFMPEG=f:\tools\ffmpeg\ffmpeg.exe
set THUMB="%%~di%%~pi%%~ni.tbn"
set MAKETHUMB=%FFMPEG% -i "%%i" -f mjpeg -t 0.001 -ss 5 -y %THUMB%

set FILES="*.avi"
set DIRS=m:\media\series i:\media\series

for /r  m:\media\series %%i in ( %FILES% ) do if not exist %THUMB% %MAKETHUMB%
for /r  i:\media\series %%i in ( %FILES% ) do if not exist %THUMB% %MAKETHUMB%
endlocal

I'd like to merge the two for loops and make use of the DIRS variable.

FYI; this was added to the Linux port branch of XBMC late yesterday:
Quote:extract frame from video files without thumb. experimental.
Let's hope this feature gets ported back to the Xbox trunk as well Wink
