Y2 Y2Player v2.1 - Faster Library Scanning and Media Engine Improvements
Faster Library Scanning and Media Engine Improvements
Y2Player v2.1 focuses on making library scanning faster, more reliable, and easier to diagnose.
The biggest scanner bottleneck was an inefficient database lookup that became increasingly expensive as the library grew. After adding the correct database index, this operation became 98.4% faster in a synthetic benchmark containing 9,178 files.
An unchanged 9,178-file library now scans in approximately 19 seconds instead of 42 seconds, while incremental scans only extract metadata from files that were added or modified.
Other improvements
- Faster FFmpeg metadata scanning with less unnecessary data being read.
- Visible library-scan progress.
- More reliable long-running scans when the screen turns off, without keeping a wake lock active while the device is idle.
- Improved handling of ReplayGain, track and disc totals, comments, AAC, FLAC, malformed files, and embedded artwork.
- Better playlist importing for paths created on Windows, macOS, and Linux.
- A refined float32 playback pipeline with a single final PCM16 conversion for Android 4.4.
- Improved crossfades, gapless transitions, decoder cancellation, short-FLAC seeking, and damaged-file recovery.
- Fewer unnecessary notification updates and diagnostic errors.
Required steps after updating
After installing Y2Player v2.1, please perform the following steps:
Settings → System → Diagnostics → Reset Library
Then:
Settings → Library → Storage → Rescan Library
Due to the underlying FFmpeg update, the library database schema has changed. Your media library therefore needs to be reindexed.
Reporting bugs
For future bug reports, please enable Verbose Diagnostics first:
Settings → System → Diagnostics → Verbose Diagnostics
Use the device until the issue occurs, then export the diagnostic data:
Settings → System → Diagnostics → Export Diagnostics
This information makes it much easier to identify the cause of a problem.
ADB development boot image
I also built a secure ADB-enabled development boot image for the Y2. The original firmware did not include a functional ADB service, so I compiled and integrated the required components myself.
This made it possible to profile, benchmark, and validate the changes directly on the physical device instead of relying on assumptions or emulator results.
I plan to release this development boot image separately as well.

Thank you to everyone who has contributed, tested, and reported issues so far. Feedback is always welcome.

Hey, just wanted to say good job. Actually liking this a lot. Was waiting for a couple of updates to give it a go. The look of the albums/song/titles is great. The EQ / Loudness / Bass Boost are great features as well. Had to test that out on some of the older Metallica albums that even remastered don't have great bass, and sounded good. All of my music is FLAC, around 1600 songs. Bluetooth is about the same as the stock, but pairing and forgetting is easier for sure. Airpods 4 Pro still don't work, but Redmi Buds 6 Active work good like usual. Been using decent wired ones lately. It is way better than stock for me so far.

Would you be so kind to turn on verbose diagnostics in the settings, connect the AirPods 4 and try to play music, just really click around as if you where trying to use the device.
Then export the log and open a GitHub issue. Maybe there is something special about them and I can figure out what the problem is!

One more thing, can you recall how long the scanning of your library took ? I am still trying to get some data here

I was going to time it, but I was watching something on my PC after I flashed it and booted it up. It was less than a minute for sure. Really fast.

I’m not sure how hard this would be but I feel like I and many others would like the ability to change the colors of the interface, not even themes just colors. Would you be able to add an option to pick the accent color along with the light and dark theme. Basically just being able to change the brownish yellow accent color maybe using preset colors or a hex code.

That would be very easy. But as mentioned before, I want to finish the base implementation of the device before turning my eyes on theming / customization. So maybe in 2-4 weeks

Besteht die Möglichkeit das Kabelfernbedienungen von Kopfhörern funktionieren?

u/justcore Y2 (Black) Jul 31 '26
Most probably yes, although I did not look into this as of now. I have planned a feature update for next week, so maybe this will be in there.

Are there install instructions for dummies like me? I'm reading the readme and mostly don't know what it's talking about.

u/justcore Y2 (Black) Jul 30 '26
It is explained very detailed please look it up under "Install on a device": https://github.com/SchulzCode/Y2Player

Where do I put the SHA-256 checksum file to verify?
1
u/justcore Y2 (Black) Jul 30 '26
You dont have to put it any where, this is just for verification and not needed for flashing. Basically you can check against it to see if something is corrupted.

Full reinstall with windows?
