How to scrap my own movies

[prog-amateur]

Hello, I have a romset wii and PS2, and their videos (snap) in my computer. I try to match them without success (because I am a beginner).
For other consoles, it is OK, the scraper integrated into emulationstation works well but those 2 consoles doesn't work work well.
I know that some tools like Selph's scraper are useful to do it, but it is not really easy to find how to do in the documentation. I could do the same for NeoGeo successfully because thegameDB and screenscraper DB have those movie data for the NeoGeo, but not for Wii or PS2.
Does anyone can help me to better understand how to do it locally (as I already have the snap videos in my computer) please ?
I am on Ubuntu but I think this information does not impact the issue.
Thank you very much for your help.

Can you give an example of what data you have - how is the ROM/CD-ISO called vs. how is the video snap named ?

Thank you @mitu , yes of course I can give you this :
ISO : a boy and his blob.iso
SNAP : A Boy and his Blob (USA).mp4

So first of all, you are right, the ISO name vs SNAP name are different. But to anticipate another question, I have tried to copy-paste a boy and his blob.isointo A Boy and his Blob (USA).isoand here it still doesn't work.

If I launch Selph's scraper, it says ERR: error processing [...] hash not foundmaybe this error code can help ?
Thank you

@prog-amateur Since you already have the videos, then you don't need the scraper to download anything and there will be no need for a hash. The Scraper can match the ROM name with the video/image/marquees names and will write the correct gamelist - see https://retropie.org.uk/docs/Scraper/#scraping-your-own-images for an example using images, but it might work also for videos. You'll have to have the same (or similar) names for both ROMs and videos and to set the folder where the scraper finds the videos, so pay attention to the command line parameters described in the page I linked.

@mitu thank you very much for your help. I will read the link you have posted and try to feedback to say if this works or not in my case.

OK time for feedback. I have succeed to download videos and boxart only, but without game description. How did I do (please, remember that I am on Ubuntu) :

• 0. download the latest Stephen's scraper program here : https://github.com/sselph/scraper/releases and put the scraper file into the wii (or the related console) directory list item
• 1. have your own videos into a folder named for example videos
• 2. download boxarts on libretro project : http://thumbnailpacks.libretro.com/ and put them into a folder named for example boxart
• 3. make sure that iso names are EXACTLY the same as boxart and videos names
• 4. use Krenamer or any other batch rename program to rename :
     -boxarts : add -imagesuffix before .png extension
     -videos : add -videosuffix before .mp4 extension
• 5. put all boxart and video files into the same folder named images (very important)
• 6. then open a terminal and go to the rom directory cd /RetroPie/roms/wii/
• 7. and put the following command : ./scraper -add_not_found=true -download_videos=false -img_format=png -download_images=false. For your information :
     -add_not_found=truemeans it adds roms that are not found as an empty gamelist entry
     -download_videos=falsemeans it checks the local videos only
     -img_format=pngmeans it checks the png files (because default check is jpg)
     -download_images=falsemeans it checks the local images only
