Hi Sebastiii,

regards our conversation, I have upload a new core.dll. Can you test it? I have replaced only an ffmpeg parameter to make a thumbnail on I_frame.

Thx!

 

[Sebastiii]

Great
You core is based of master ?
Can you supply the change too, will be more easy for me to test

 

[regeszter]

yes, based on master.

in VideoThumbCreator.cs

-		string ffmpegFallbackArgs = string.Format("select=isnan(prev_selected_t)+gte(t-prev_selected_t" + "\\" + ",{0}),yadif=0:-1:0,scale=600:337,setsar=1:1,tile={1}x{2}", 5, PreviewColumns, PreviewRows);
+		string ffmpegFallbackArgs = string.Format("select=select=eq(pict_type\\,I),yadif=0:-1:0,scale=600:337,setsar=1:1,tile={1}x{2}", 5, PreviewColumns, PreviewRows);
 
 
and
 
 
-			ffmpegArgs = string.Format("select=isnan(prev_selected_t)+gte(t-prev_selected_t" + "\\" + ",{0}),yadif=0:-1:0,scale=600:337,setsar=1:1,tile={1}x{2}", 1, 1, 1);
+			ffmpegArgs = string.Format("select=eq(pict_type\\,I),yadif=0:-1:0,scale=600:337,setsar=1:1,tile=1x1");

Just tested, nope it's worst
I get Grey thumb and generate one on video .ts is very slow.
So right now that not good lol

 

[Sebastiii]

Hmm wait i will retest on avi files it seems better

 

[Sebastiii]

Ok it's seems a little slower (but not much for .avi) = thumbs are ok
For .ts video it's too slow but seems ok.

I just try with xbmc and tile 1x1 and i also get grey thumbs for .ts.

 

[regeszter]

I have never get grey thumbnails for ts, avi or mvk.

I have never get grey thumbnails for ts, avi or mvk.

I"m getting them also very easily.

Somehow i'm unable to upload the thumbs (as picture, so they're in the zip):
