[SOFT] New Scraper in the works

So for me it would be nice to find a good solution for generating gamelists that can be shared from within the script or perhaps could even be scraped from within the script.

We already have some predefined gamelists with media that can be downloaded from within the script for the categories :
konamih, tigerh , etc. (many done by @DTEAM)

The script can install arcade categories like "shooter" or "pinball" too.
However, for these categories there aren't predefined gamelists with media yet.
Sadly these "categories" are not recognised by your scraper.
Basically not a big problem so I renamed them to arcade and scraped them and renamed them back.
Now I should have a proper gamelist+media, right.
Well It doesn't work that way because the gamelist.xml contains full paths to files so I have to rename the roms directory from /arcade/ to /shooter/ to get it working again.

Well, we had a different approach with our predefined gamelists.
For our predefined gamelists, have a look here :
https://drive.google.com/drive/folders/1f_jXMG0XMBdyOOBpz8CHM6AFj9vC1R6m
You will see that we use relative paths rather than full paths.
This solution makes it easier to copy to an other named folder or to a computer with an other username without editing the gamelist.xml.
So my question is, could you incorporate that solution ?

We also set the images/videos in the directory media/emulationstation/ .
Which emphases that the media is used by emulationstation.
So when running emulationstation only 1 media folder is seen instead of images/marquees/videos.
I would like you to think about this too.
For your folder it would mean :
media/emulationstation/images
media/emulationstation/marquees
media/emulationstation/videos

If you see something in both suggestions then we apply somewhat the same "standard" to the gamelists.
With this we could somehow join some forces.

What do you think ?
Let me know.

@Folly Hi, Sure it makes sense! I'm away this weekend but will put this as new features in the upcoming versions. I just need some time to understand exactly what's done.

I believe that we could actually have the same gamelists created from my scraper, without the need to actually have 'predefined' gamelists.

I'll definitely have a look.

By the way, my scraper takes into accounts arcade systems such as 'Capcom classics', 'konami classics' and so forth, this is an example of my es_system for some of these classics:

  <system>
    <name>atariclassics</name>
    <extension> .7z .cue .fba .iso .zip .7Z .CUE .FBA .ISO .ZIP</extension>
    <platform>arcade</platform>
    <theme>arcadeatariclassics</theme>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ arcade %ROM%</command>
    <path>../roms/atariclassics</path>
    <fullname>Atari Classics</fullname>
  </system>

The scraper will match the name tag 'atariclassics' in this example.

Ok, nice to hear you agree.
Would really be great if you could accomplish that.

So if I can somehow add <platform>arcade</platform> to a category then it should be recognised right ?

kiro

@Folly You do not need to add anything like 'platform'.... my scraper recognizes the roms based on their checksum, not their names, directories or anything. In principle, you could put all roms into a single directory and it would recognize them as long as their checksum is in the database.
If the checksum is not in the database then the <name> tag will help the scraper try to figure out the game, but it is not mandatory.

To answer your question about the <platform>, I'm not sure why this tag is there, it is not taken into consideration by the scraper :-).

@kiro

Somehow my categories are not recognised by your script so I can't select them in the systems menu.
This is an example of such category from the es_systems.cfg :

<system>
  <name>shooter</name>
  <fullname>shooter</fullname>
  <path>/home/pi/RetroPie/roms/shooter</path>
  <extension>.cmd .zip .7z  .CMD .ZIP .7Z </extension>
  <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ shooter %ROM%</command>
  <platform>shooter</platform>
  <theme>shooter</theme>
</system>

Indeed, changing it to <platform>arcade</platform> doesn't help also.

kiro

@Folly yes, it will not recognize such 'custom' categories...maybe I should think on way to imrpove this. As I said this should not matter if the checksums are found in the DB. Maybe I should think of an alternative here... Let me have a think this weekend

If you can do all of that it would definitely be an improvement ;-)

Hi,

Scanning on the arcade directory still gives me videos with the .png extension in the video directory, though some are good with .mp4.
I have .png files in the folders images and marquees, so that seems to be OK.

After this discovery I tried archimedes again.
This is good, no videos with .png extension.

So there still seems to be an issue with videos called .png in the videos directory for other systems.

kiro

@Folly thanks! The fact that there are still .PNG files in the video directory might be due to them still being there from previous scraps. Try using the "cleanmedia" option or --cleanmedia if running from command line. Let me know how it goes.

Folly

@kiro

I removed all files manually.
Now I am also using your retroscraper-rpie which does the same.
I am seeing the files being added in the file-explorer.
So definitely an issue.

I also noticed that there are many videos that will not display, sound on the other hand is played though.
Could it be that some codecs are missing ?
I tried some files in VLC and gave me black screen but sound is there.

kiro

@Folly thanks, I'll have a look when I'm back home on Monday, I might need to revalidate the videos. Will also check about the PNG thing, definitely strange.

Folly

@kiro

If I can implement the setup somehow in my script then your retroscraper-rpie would probably be easy enough to add in my script.
I will have to think about it some time.

kiro

@Folly thanks! I actually do have a script which is running (installation goes fine as well as execution) based on scraper.sh script. My only concern right now is that output is buffered, so it seems (only seems) as if the scraper freezes.
But thanks for the offer, definitely we can talk about doing something together.

Folly

@kiro

I just did atari7800, although it also has the .png video issue, all videos and pictures are good.
I must say if something is recognised then recognition seems to be perfect.
I do not see that with other scraper methods.
I also notice that the scraping is very fast, much faster that other scrape methods.
Really nice !!!

Folly

@kiro

For your information.
I am testing your retroscraper-rpie now in my Debian11-x86_64 in VMWARE.
Looks like the .png problem for videos doesn't occur there.
Also the gamelist.xml contain the correct naming for the videos (.mp4)
So this problem could be specific for the RPI/raspbian/raspbian version.

ALL video seem to be playing correctly in emulationstation in my VM, although, for some videos, emulationstation seems to give errors like this :

[src/libmpg123/layer3.c:2184] error: part2_3_length (1408) too large for available bit count (1368)

Could it be that some videos are not that compatible or have some corruption ?
