Is SF's shell service down? I can't connect to shell.sourceforge.net anymore...

Edit: Thx for confirmation, Haruhiko!
Edit2: It's working as of now!

Yes. I can't connect too.

Is there a way to decode *.jpg files with ffdshow? Cause I would like to watch my vacation pics on TV with some sharpenfilter (or something similar).

At present it looks like that on my system:

If you enable "Raw video" in the Codecs list, you should be able to put ffdshow between "Color Space Converter" and "Video Renderer".
Maybe the "Color Space Converter" won't even be needed then ...

You could use Irfanview. That has a sharpen filter.

I can put ffdshow video decoder after color space converter (before it isn't possible) but then I can't connect to any video renderer.... any ideas?

thx for the tip, but I don't see an option for sharpening on the fly (e.g. slideshow) with Irfanview.

@ mods: if this is way too OT, feel free to place it somewhere else

What does the properties dialog for the "Out" pin of the ffdshow raw decoder show? That could give a hint as to why nothing wants to connect...

(Or you could run DbgView from Sysinternals and look if any messages turn up in it...)

I don't know why, but now it works
(I can't remember what I changed exactly) - thank you all.


unfortunately seesaw scipt in avisynth dialog doesn't seem to work... but sharpen should be enough for the moment

I haven't ever used SeeSaw, but given that all kinds of other filters and scripts work I can't think of a reason why SeeSaw wouldn't...

Maybe I wasn't clear enough:
SeeSaw does work in avisynth dialog for videos. But not for jpgs (at least here)

[clsid]

Since a jpg can be considered as a movie with a length of just 1 frame, any filter that need multiple frames to work on, won't work. I dunno if that applies to SeeSaw.

[Didée]

SeeSaw requires YV12 as input, because of MaskTools. The decoder probably delivers the JPGs as YUY2 or RGB, so you've to use ConvertToYV12() before SeeSaw. While you're at it, set 'sootheT=0', because temporal soothing makes no sense for single image sequences.

It's damn slow for Hi-Res files but it works with SeeSaw now

A ConvertToYV12() is not needed, if one is limiting colorspaces to yv12 in avisynth dialog


for the hint, Didée!

1. In IrfanView v4.10 goto "File" -> "Batch Convert/Rename"
2. Add all the files you want to view
3. Choose "Work as: Batch conversion"
4. Choose the output directory as you like it
5. Check "Use Advanced Options" and click "Advanced" button
6. Under "Other Options" (right side) check "Sharpen"
7. Click "Okay" and "Start Batch"
8. Use "File" -> "Slideshow" as usual (from output directory)

[kurt]

@ Lord_Mulder: yup, I'm aware of batch-processing. I have Paintshop Pro installed and could do this also with it. But I don't want to convert my pics (they are sharpen enough) - the TV is the problem. For my taste the pics on TV could be a bit sharper, this is why I asked for ffdshow.

Regarding Irfanview: I thought maybe it has an option to enable some sharpen filters during slideshows, but this seems not the case. Now I will try, wich filter in ffdshow (sharpen, seesaw..) is satisfying - if I find some time

(reminder: this is all about JPGs - with videos I don't have any sharpening problems on my TV because of SeeSaw)

Edit: hmmm, maybe batch processing is really easier (and faster in the end) to handle since mpc/ffdshow/seesaw is not specially made for playing back images (and it takes a lot of cpu time switching between the pics). Convert the pics you want to use for a slideshow and just delete them later .... I have to reconsider

[foxyshadis]

Well, you should really use SeeSaw after resizing, so high-res shouldn't be a problem done properly. But yeah, it's best to batch convert everything into a folder, sized directly to the screen's dimensions, to get the best quality at a good speed.

jup, I tried lanczosresize(1024,768) yesterday and it suited well on my CRT TV - but it is still very slow (P4, 2 ghz, 512 MB RAM)...

The code change itself should be rather minimal, but the implications might not be. What does the rest here think?

np: Luke Vibert - Comphex (Chicago, Detroit, Redruth)

Sorry to be too late, but I guess this change is confusing the user. We are not announcing this very loudly. People who don't read here have no way to know...
'on movie file name match with preset name' is checked by default and unless users uncheck it, the preset doesn't load.
Too late but isn't it better to add an option to select OR/AND and make OR the default?

The dialog would require a radio button
*On all conditions match (AND)
*On one of the conditoins match (OR)

[clsid]

Or maybe uncheck 'on movie file name match with preset name' by default. I don't think many people are actually using that condition.

Yes, I will.
But it doesn't rescue user's old preset.
