RockBox album art support

[awesomunia]

Thank you for the interesting commentary.

I really like the LCD of the iPod mini being able to display album art.
Even if it can be displayed on the latest iPhone, I don't think it feels great.

Sure, single-core machines are slower than today's multi-core PCs, but you can finally get the results.

I asked for a vote on the RedditRockBox bulletin board.
I'm purely interested in how much users want png support.

I don't know that it matters how much users want it, the issue, as I understand it (I think I asked about it myself a long time ago) is that it's not really possible, because, as explained in this thread, it requires more computational power (and RAM?) than standalone DAPs have.  If it can't be done, it doesn't matter how much people want it.  I still don't really understand why you can't just convert all your embedded art to jpg and be done with it.

Have you seen "impossible" on all supported devices?  The latest version of RockBox also supports the 6th generation ipod, and the device is evolving.  Then I'm just wondering how much the user wants, I don't claim it's important.

Also, it's easy to convert to jpg, but that means modifying the original you purchased.  Rockbox isn't the only time itunes users listen to music.  I think we should increase rockbox support if compatibility is important.  Also, I haven't received a clear response to asking many questions.  Does RockBox permanently not support png?

I have an Ipod Mini. Being able to display album art on it is kinda cool, but pretty useless due to the limited palette (2 bit plus dithering on a rather small resolution gives you rectangle with something remotely resembling the album art at most but not more.)

It doesn't matter.

Rockbox is not a product people are getting paid to work on. People work on it in their spare time, and the times we had like 20 active developers are long gone. So unless you're the developer trying to figure what to work on next it won't make a difference. There are tons of feature request we had over the years that nobody implemented simply because nobody was interested enough. It took years until we even got album art support in the first place.

Also, it's easy to convert to jpg, but that means modifying the original you purchased.

No it does not. You can easily save the files separately. No need to modify anything. You can even store the files in a separate location (see the manual on where / how Rockbox looks for album art.)

Thank you, Blue Brother

I think the answer was convincing.

When I was in elementary school, the iPod touch was already on sale.
The iPod, which can only play music, wasn't a prominent product at the time, but I was interested in videos about the recent YouTuber iPod.

And recently I bought an iPod mini.
And I got to know RockBox.
It's not very practical, but I'm very happy to see it on the LCD even if the cover art of my favorite artist isn't clear.
This is similar to the excitement of watching a recent show on black and white TV.

Attempts to save the art to a directory once using the suggested method.

However, I haven't given up on getting interested users like me to implement this feature.

Wait patiently.

Even if all of your artwork is in the proper format already, in my experience their resolution is often much too high for Rockbox (at least on older devices) to speedily display. Recent Bandcamp purchases of mine came with JPGs that were a few MBs large I think.

For Rockbox on b&w iPods, I usually remove all embedded art from the files after adding a folder.jpg of the original album artwork (for other software to use when I have the iPod connected to my computer) and then create a second file resized to a maximum height of 128 pixels from it, whose name I set to the title of the album. That works out perfectly considering the order Rockbox uses when looking for a picture (albumtitle.jpg is prioritized over folder.jpg), as mentioned by bluebrother.

Re PNG images and even the capitalized file names I suppose
The lua plugin is ideal for these requests

The script side of this can be done on device with the lua plugin

I've already included code in the examples to decode and encode jpeg images
it would be less work and more extensible than changing Rockbox to suit these
requests

I definitely want to see it.
I would like to see if I can convert that script for png!

[Bilgus]

oh sorry I meant encode bmp images not that jpeg is any less possible

the script that uses it is under .rockbox/rocks/demos/lua_scripts/rlimg.lua

and the source file for the bmp encoder is .rockbox/rocks/viewers/lua/image_save.lua

[awesomunia]

Thank you, Bilgus.
I will try to create an extension with reference to the source!
