Repairing and Upgrading Rockbox Capable Players / XDUOO xiii repair

« Last post by silverbear on Today at 01:52:32 PM »

My XDUOO has developed an a dodgy play/pause button. I'm pretty sure it's a hardware problem. Has anyone else had this problem? Was it repairable and any recommendations as to where this might be done?

Rockbox General Discussion / Re: Seamless play

I've noticed that since updating to 4.0 that gapless is broken.  This is with the same files that used to work gapless in 3.14.  Has anyone else noticed this?

Comparing 4.0 from 2025 to 3.14 from 2017 will require more clues.

I have not noticed any gapless problems on 4.0.

Audio Playback, Database and Playlists / Re: Looking for the most efficient (easiest to decode) format for iPod 5

« Last post by K4sum1 on Today at 10:29:04 AM »

Those opus benchmarks are a reminder that I really need to optimize the non-power-of-2 FFT. Been on my to-do list for 12 years now.

I would be curious how a well optimized Opus decoder would fare on the iPod. Although even if it's a substantial leap maybe I'd still want to go with ogg because VLC seems to have a weird delay playing Opus files for me.

I was also curious how Vorbis encoders fare, and I also discovered a tool called OptiVorbis which (slightly) decreases file size without any impact on quality (the spectrals are the same) So I ran some tests using my own custom files. I also wanted to see how fast wav would decode.

aoTuV is barely slightly slower to decode than libvorbis, and files run through OptiVorbis are barely slightly slower as well, but outside of being barely measurably slower here, it's way too small to be noticeable in normal use.

People say aoTuV is better, but the spectrals from libvorbis look better to me. A lot of the discussion about aoTuV being better is ancient too. However it still seems aoTuV may still have some improvements, but I'm not sure how to quantify them. I know I could do some like blind test, but I feel like I wouldn't be able to notice the difference so I don't even want to try and have been trying to find some scientific or test collection that isn't ancient to point me towards what to use, but that just doesn't seem to exist or I can't find it.

Also the wav result is insane.

Audio Playback, Database and Playlists / Re: Gapless is broken in 4.0?

« Last post by speachy on Today at 09:23:17 AM »

I've noticed that gapless playback is now broken on my iPod Mini running 4.0.  It used to work when running previous versions.  Has anyone else noticed this?

As with every other problem report involving playback, without specifics on the files in question, there isn't much that can be done.

(In other words, please follow the "bugs" link on the sidebar, create a bug report with as much detail as possible, including two of the files that fail to work in a gapless manner)

Theming and Appearance Customization / Re: Where should I place fonts that only display icons/graphics?

« Last post by Dook on Today at 08:01:36 AM »

Just checked this, rockbox refuses to load the theme unless fonts end in the .fnt extensions.

Will it work with  ".fnticons"? If I'm not mistaken it should work with any extension that starts with .fnt:
https://github.com/Rockbox/rockbox/blob/944026f2b752cb7b6934c399954d67e1f75bb2ac/apps/gui/skin_engine/skin_parser.c#L490C1-L494C40

You're right! That works, and as you theorized it doesn't show up in the menu too. Great to know you can do this.

Given their unconventional nature, it seems more logical to me to put those specialized non-text .fnt files in the theme's folder within the WPS directory rather than in the Fonts directory.  Also, giving them filenames that are as descriptive as possible, as well as providing an accompanying README file, would help to make their intended purpose and use clear.

Wherever they end up, I'm intrigued and eager to see what they look like.

Great points on the descriptive filenames and README. It might be a good idea to put a reference table in it to communicate the contents of each file as well.

Audio Playback, Database and Playlists / Re: Ipod Nano Gen 2 wont build database, doesnt write to metadata.log

Never mind, it literally just fixed itself overnight.

I wish i could say how i fixed it, or why it didnt fix itself at all in the past 3 days but oh well.
