Recording thumbnails - resolved! :-D (2 Viewers)

[Wo0zy]

Thanks for doing this pilehave.

My recordings thumbnails (or lack there of) has been a bit frustrating.

Are you still using the code you quoted earlier or have you tweaked it for the tests?

All the best,

Mick

I tweaked the code a bit more. This is what I have so far, a cleanup is needed

Hello,

the solution doesn't work for me anymore, because the tweaked TV.dll file is not compatible with MP 1.2.1. Can you compile it maybe? Because this solution works like a charm for me!

Hello,

Same problem here, a new version of the tweaked dll would be great.

Thanks.

If any of you would like to try the solution I had on my problems, you are more than welcome.

It uses ffmpeg to create the thumbnails. It doesn't have the blur-detection of the old thumbnailer, but I haven't found that to be an issue yet. It has created thumbnails of all of my +500 recordings.

You need two files:

- replacement Utils.dll
- ffmpeg.exe

Put Utils.dll in C:\Program Files (x86)\Team MediaPortal\MediaPortal (remember to make a backup of your existing Utils.dll first!)
Put ffmpeg.exe in C:\Program Files (x86)\Team MediaPortal\MediaPortal\MovieThumbnailer

This should be enough. MediaPortal keeps track in the database what files failed to generate a thumbnail, so new files won't be re-created automatically. If you want this you need to edit the MySQL/ MS SQL database (let me know, and I'll explain).

Both files are attached. The ffmpeg.exe is for 64-bit only! Get a 32-bit version from http://ffmpeg.zeranoe.com/builds/

I'm not sure if you also need a replacement Core.dll, but I don't think so!

Thanks pilehave,

I assume this solution is only good if you use MP TVServer, I'm using FTR.

John.

I would think so, I believe FTR creates its own TV-thumbnails. The Util I posted is used by MP to create thumbnails not only for TV, but for videos as well.

 

[01-0077]

Yes FTR generates its own thumbnails using mtn. I believe FTR uses either a different version of mtn or different mtn switches to TVServer. I have found FTR is more successful at producing recorded tv thumbs for our HD channels than TVServer but its still not 100%. Is it possible to run ffmpeg on a recording from a command line?

Yes it is.

It uses these args:

string ExtractorArgs = string.Format(" -ss {0} -itsoffset -5 -i \"{1}\" -vframes 1 \"{2}\"", preGapSec, aVideoPath, OutputThumb);

which translates into something like

ffmpeg.exe -ss 720 -itsoffet -5 -i "path/to/videofile" -vframes 1 "path/to/thumbnailname.jpg"

All of this is trivially explained in ffmpeg Documentation

 

[01-0077]

Thanks pilehave, the reason I asked was because I couldn't get the version you posted to run from a command prompt. Is it 64 bit, I'm on x86? I downloaded a 32 bit version and it works a treat.

I found the ffmpeg documentation in one of your earlier posts. Quickly found out that for a performance boost to make sure the -ss argument is before the -i, this way ffmpeg jumps straight to that position without decoding first.

A while back I had a play with a filewatcher app which monitors a folder and when a file is created will call another program to run on the file. I used this with mtn with limited success (due to mtn), but I might have a go with ffmpeg and see how it goes. This runs as a service and I can just disable thumb generation in FTR.
