Shanling Q1

[raffraffraff]

Two interesting things:

1. I just got an out-of-memory panic:

*PANIC*
audio_reset_buffer(): OOM!

Right before this happened, I had plugged it into USB, rsynced tracks and playlists to it, ejected it and finally asked Rockbox to initialize the database. (After the panic, I restarted it, and it displayed the message "Committing database [1/10]" and then continued to start up.


2. My playlists are only showing the track title, no artist. The playlists I copied have EXTINF data, so Rockbox seems to be ignoring that. Is this normal? All I can find on the subject is this: https://www.rockbox.org/tracker/task/7652

[raffraffraff]

Probably related to the panic, but the database never rebuilt itself. It seems to be stuck at "Building database... 7934 found (OFF to return)". I'll go debug that. Probably nothing to do with the Shanling port.

Is parametric equalizer  working fine?

I am interested in purchasing this device

The EQ works well. It's a core feature available on all devices supported by Rockbox.

I have bought one of the last Shanling Q1's from Shenzenaudio. I have used Rockbox version 1.4 years ago on a Archos Studio. At the beginning of this year I have bought my first iPod (mini gen 2), replaced the battery and converted it to 256 GB flash storage. I am very happy with this iPod running Rockbox. So I used the opportunity to buy a new player which can run Rockbox, specially one with a touch screen.

Having said that, themes working well with touch are rare. So I have converted my (not yet published) theme Oscar from my iPod mini to the Shanling Q1. I have implemented a wps which can be used in "absolute point" mode. With this theme I am quite happy to run Rockbox on a touch device. Therefore I have uploaded this theme to themes.rockbox.org as "Oscar Q1".

Remember to turn on "absolute point" mode yourself, as it is not allowed to be set in the themes config file.

I have made the second update to the theme "Oscar Q1". It now hides the touch area symbols, while the device is locked.

While working on the theme, I have struggled a lot with memory. Sometimes the wps would not load at all. Other times it displayed screen artefacts in the graphics, mostly the cover art, Sometimes some random objects (images/viewports?) would not display at all. Also when using the theme "lebellium Samsung-like", the cover art would not be shown on my device. One reason could be, that my cover images have typically a size of 700x700 pixels. Another reason could be the touch areas. Is my assumption about memory constrains correct? Could the theme memory (objects, images etc.) be increased for the Q1 build? I guess bigger screens call for more memory.

BTW Finally I have released my iPod mini themes "Oscar" and "Oscar cover".

[amachronic]

Memory usage shouldn't be a problem. The theme engine will allocate as much as it needs, and the Q1 has 64 MB of RAM which is a lot by rockbox standards. If you're hitting a bug or a theme engine limitation you'll need to provide more info, preferably a test case that shows the problem (as minimal as you can make it), and explain what you expect it should do, otherwise nobody will be able to help.

Also, thanks for the theme! I'll try it out on my Q1.

[Oscar]

Thanks for the answer. At the moment I am happy with the result. But when I will stumble about a problem in the future expanding the theme, I will try to make a test case.

I relly luv your theme, is there any chance to make a dark version? White is too agressive for night use

Yes, have a look at https://themes.rockbox.org/index.php?target=shanlingq1. ;-)

Thanks a lot!

Thanks Oscar for this nice theme, it really makes it easier to use the player.

Amachronic, I have a potential bug report. I could be using the functionality completely wrong, but the (Meier) crossfeed doesn't seem to be doing anything? I understand that the effect is subtle, but even when I tinker with the settings, nothing seems to happen. I've used Meier crossfeed on other devices and programs, and I kind of know what to look for in terms of sound. Anyone else who could try it and hear if they have a problem with this?

Also, a lot of artwork doesn't want to show up. I often do extensive tagging of my files, either via MusicBrainz Picard or MP3-tag, and I always both embed and add a cover.jpg or folder.jpg in the album folder. Despite this, it often doesn't show up. Could this have to do with differences in jpg-compression codecs or certain resolutions? Maybe this is just a general rockbox problem.

Anyhow, no stress in looking this all up, just wanted to report.

Most of the time, when a cover art doesn't show up in my collection, it is embeded as progressive Jpeg, which is not supported by Rockbox. In that case I extract the image from the MP3-file with Mp3tag (a great ID3 tagger for Windows), load the image into irfanView (a image viewer for windows), save it (non progressive), and re-embed it into the MP3 with Mp3tag.

Most of my cover art is 700x700 pixels which is on the large side for Rockbox, but most of the time they do display with no problem.

That makes sense, Oscar. Thanks for the info! I might just use a program as RIOT, and convert the existing file. There is also this nice little tool called Album Art Downloader which scrubs relevant websites for album artwork, and then I can just convert it.
