[SOFT] New Scraper in the works

@Folly I just tried that video and it works for me ...

Could you try it on another pc maybe?

Folly

@kiro

It played from within your 'frontend' on my pi.
Will try a VM to see what it does.

Not home now, but I will run it from the CLI on the pi when I can.
Just to see if it gives some useful info.

Just tried on my VM Bulleseye X86_64 but I get this message now :

$ python3 retroscraper.py --systems playchoice10

SCRAPPING ENDED --- Thank you for using retroscraper!!

Could be that I am getting blocked or having a bad internet connection.
Will do an update and try again later.

kiro

@Folly Hmm this seems like another issue.... can you use the --debug feature??

By the way I've updated the script in the repo as there was a bug with the debug function (It always went debug)

Folly

@kiro

I am traveling now on a boot for my work and I am almost on my destination so have to work soon.

Will do it later today ;-)

kiro

@Folly Sure! no worries! I have the same issue :-)

Also, pls check if playchoice10 is the name of your system in es_systems:

  <system>
    <name>playchoice10</name>
   .....
  </system>

Just trying to discard issues.
Thx!

@kiro

It's not working on the pi4 so the issue seems to be pi related.

Though it's working in the VM and the video plays and the others seem to work too.

This is the VLC output of pc_mario.mp4 only playing sound on the PI4 :

This is the VLC output of moglf.mp4 playing both video and sound on the PI4 :

ffmpeg gives these video formats :

pc_moglf.mp4 :

    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 640x480 [SAR 1:1 DAR 4:3], 143 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)

@Folly Thanks a lot for the testing! Really appreciate it, so hopefully, the video issue is solved.

I started working on the relative paths, --relativepaths is added as an option and should put everything in the gamelist under a relative path. Let me know when you have tested (no urgency).

Tomorrow I'll add the --mediadir option ;-)

Thanks!

Sadly no, not on the pi4.
Unless you changed something with the videos.

What do you think, looking at the VLC logs ?

kiro

@Folly, I might have said the wrong way :-) The scraper is downloading the videos properly, but, some of the videos in the backend are encoded in a way the pi is not able to display. I'll dig into that today trying to understand what's the difference between a working and a non-working video so I can eventually re-encode those not working. Will keep you updated.

This is the encoding for the pc-mario video:

Stream #0:0(und): Video: h264 (High 4:4:4 Predictive) (avc1 / 0x31637661), yuv444p, 512x480 [SAR 5:4 DAR 4:3], 74 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)

This is the encoding for a working video:

Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 640x480 [SAR 1:1 DAR 4:3], 143 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)

The only differences I see are the (high) and yuv as well as resolution.... any idea (any expert reading this) why the first video would not play on a pi?

I've tried converting from high 4:4:4 predictive to just high and it seems to be working:

I'll be creating a script soon to run over all videos and convert those under the same predictive profile.

Will keep you updated.

I saw that your computer had somewhat the same error, although it played well.

I will see what my VM says with the old pc_mario.mp4 and try the new one on my VM and PI4 when I am home again.

My VM gives the same errors, although it plays :

[src/libmpg123/layer3.c:2184] error: part2_3_length (1536) too large for available bit count (1368)
[00007f15f4003510] gl gl: Initialized libplacebo v2.72.0 (API v72)
[00007f15f47c4080] chain filter error: Too high level of recursion (3)
[00007f15f47c7690] main filter error: Failed to create video converter
.. many more chain/main errors
[00007f15f40013b0] main vout display error: Failed to adapt decoder format to display
[00007f15f40013b0] main vout display error: Failed to adapt decoder format to display
[00007f15f00484b0] main video output error: video output creation failed
[00007f1604c74da0] main decoder error: failed to create video output

As you said it looks like the video has issues.

I renewed the video on my VM.
Succes, the errors are gone for pc_mario.mp4 !

Folly

@kiro

Tested --relativepaths :

pi@Bullseye-VM:~/retroscraper-rpie$ python3 retroscraper.py --systems playchoice10 --relativepaths

Perfect !

kiro

@Folly Nice! Thanks!

I'm going through all the videos with this 'Predictive' profile to fix them. Once this is done I'll start with the --mediadir flag.

Again, thanks a lot for all this testing.

Folly

@kiro

Good idea.
Not tested yet on my pi4, but indeed, when all videos are converted they probably will work too.

Wanted to ask.
Does the script have the ability to scan also subfolders ?

Folly

@kiro

As far as I know you removed the backup function for gamelist.xml.
If so you can remove it from the --help
~~--nobackup Do not backup gamelist.xml file~~

kiro

@Folly Hi, the backup functionality was not removed, at least not intentionally :-) Is it not doing backups anymore?

Also, it will in principle scan subdirs, and exclude '/videos/', '/images/' and '/marquees/' from the scan.. although I have not tested it (I do not have subfolders in my rom collection honestly)

Although thinking about it, probably the --relativepath option will not work in this case due to how I extract the path from the filename... will have to rethink the relative logic...

Folly

@kiro

By default the backup function doesn't work anymore, so you should look at this.

I did a test with placing the megaplay roms directory inside playchoice10.
Then the subfolder isn't scanned/detected.

Will do a second test with a subfolder.
Placed some playchoice10 files in a subfolder and indeed they aren't detected.

kiro

@Folly Will check on the default backup issue.... and will put the subfolders in my todo list :-)

backup should be ok now...(it was a matter of the logic being inverted)

Folly

@kiro

By default backing up gamelist.xml works again.
Tested the --nobackup function and that works too.

kiro

@Folly thanks! Yes the double negative logic just screwed with my brain...
