Hello,

I noticed a lot of the preview movies in Mednafenx have slowdown. For instance, when you select the game with one of these movies that is slow, the movie and sound is choppy. Also, the down and up arrow animations slow to a crawl. The emulator is running at 480P.

I started to make a list, but then I realized its a LOT of games and its late and I need to get to bed...

:|

Anyway, here are some with very noticeable slowdown:

10 Yard Fight
1919
1942
1943
3-D Battles
720
75 Bingo
8 Eyes
A Boy and His Blob

Not all the movies have slowdown. A good example is Super Mario Bros & Duck Hunt & WCTM. That video looks great and plays fine with no processor lag.

I'm guessing this is caused by how the video was encoded.

Can anyone else reproduce this problem? We should probably compile a list for Rx.





UPDATE: Forget it, I just went back to the list again and now the slowdown is gone. Weird.

Guess its a false alarm. Is it possible that the RAM got filled up?


ANOTHER UPDATE:

Ok, there is definitely an issue here. Good thing is, I think it can be reproduced easily. The slowdown happens after launching a game and then quiting and returning to the ROM list. As I said earlier, some videos are OK, while others (most unfortunately) show slowdown and cause the interface to get choppy.

Can someone else please check this on their system so we can confirm this and if its a bug, report it to Madmab?

Thanks!

This problem could be a multitude of things.

First thing to try is an option.
Configuration/Video Configuration/Screenshots,Movie Preview Settings.
Show screenshots while scrolling = Yes/No. Set to "No"
This will still display your screenshots but i think it loads just the set you wish to view.

Second thing could be the artwork itself.
Some of the BoxArt in the older packs were random sizes.
These should be resized to a standard form.
If they are 640 tall try resizing them to 318 tall (width in ratio).
The smaller files load much faster and require less resources.
Future packs "may" fix this.
Screenshots may or may not be random sizes. ie 640x480 or 640x448 etc.
These could be resized to 320x240 or 320x224. This will also help the emulator
and not decrease your viewing pleasure. I personally take the screenshots a
stage further by reducing them to a 256 colour palette too. Now this is ok for me
as i use video as my main preview plus i see no noticable degrading of the screenshots.

Third is the video itself.
These could again be older packs that were randomly collected from the internet.
They could be varying sizes and bitrates. You could re-encode them all to a standard format yourself
or wait for an updated, standardised pack. Whether this is on the cards or not i don't know.
If i remember correctly the filesizes and length of video were all over the place.

Hope that helps a little.

Another note.

Depends on where your artwork is situated and what format are the filenames.
Are you using the old method ie- E:\Screenshots\MednafenX NES\0.png, 1.png etc.
This "for me anyway" seemed to cause lags.
I moved the screenshots to the emulators internal folder structure and named them accordingly.
ie- MednafenX\Media\Artwork\BoxFront. etc.
This helped lots. In fact it made all the difference for me.
Rx recommends moving them all to a central directory ie- F:\Media\Artwork\NES or similar.

I haven't looked at the NES emulator for months now so im basing this on what i remember
and the fact that the NeoGenesis one works in a similar way.
New packs next month may solve all these problems anyway.

Hello,

I'm using the most recent video/art packs that are available. I realize these are being updates in March. I'm also following the new file directory system that was recently introduced.

I think you're right in that some of the videos that are running slow are either larger or at a higher bitrate. Whether this has been looked at for the final Xtras editon, only Rx can answer. smile.gif

RX, is this the case?

Did you try this ?

Configuration/Video Configuration/Screenshots,Movie Preview Settings.
Show screenshots while scrolling = Yes/No. Set to "No"

Hey Cbagy,

Yes, that was set to 'No'

I'm including a screenshot below comparing two videos, 3-D Battles of World Runner - Part II and 100 World Story. You'll see that while they are the same size, there are differences in the two files. The input bitrate is much higher in 3-D Battles, which would explain why it sometimes plays choppy while 100 World Story doesn't. I'm not an expert at this, so maybe one of you guys can figure out what the issue is and how to correct it.

Also, this doesn't happen all the time. I think (again, not 100% sure) that when you play certain games or a number of games, the ram gets used up and there isn't much left for the previews/GUI, which is why some videos that are more taxing on the system show themselves.

Anyway, I hope this helps out.

What delay time do you have set between screenshots and where are you loading the movies, screenshots, and box/cart art and ROMS from? Local xbox or across a network.

Hello Madmab,

I believe its set to the default of 3. The movies and all other artfiles are located on the Xbox HD. I don't do the network thing since I have a 300 gig hard drive.

I think its your BoxArt and/or ScreenShots.
Those videos birtates are ok.

The art files I'm using are from Rx as well. I don't think its those, since some movies play OK, while other do not. There is a difference in bitrate on the two movie files I showed as examples.

I'm not an expert, but Madmab is now aware of this and I'm sure he is looking into it.

Thanks again for your suggestions Cbagy.

Was just talking to gilles999 and it sounded like he had a similar issue that cleared up after removing the files from the "e:\saves\nes" directory, or whatever is the one that mednafen uses. Not the actually "saves" themselves, but the other files like the ".ini" files, etc.

That would make sense. I'll check it out. As I said previously, it only happens occasionally. smile.gif

Also, the default directory is e:/saves/mednafen_nes biggrin.gif
