AGPTEK Rocker

[Markfm]

Yes, it is possible. I tested playback to bt headphones. Unfortunately can't remember details - it was quite some time ago.

Did you have a chance to check your notes on this?  I'd really love going to Rockbox on the Benjie, but working bluetooth is key for me.

Thanks so much for the work you've done on this

Like a lot of other users, my Sansa Clip+ player died on me recently, flash corrupted won't boot anymore.

I was browsing around Amazon and the AGPTEK player was advertised as "rockbox compatible".
There was even a piece of instruction on the product's page

Compatible with Rockbox system by update the latest Firmware.Note: you need to go to agptek com-blog, input"ROCKER Firmware Update" in search box to find the latest firmware to update your mp3.

Followed the instructions which leads to this download
http://images.agptek.us/Download/AGPTEK_Rocker%20firmware%20update(20181207).zip

The ZIP file contains a pdf with instructions and two other links.
1. rockbox.zip

2. update_rb.upt

These are the files I used to update the AGPTEK player  with rockbox
I eventually updated the .rockbox folder with this version, agptek Version: ed269affb5-190208.

Here are the results of the testing I've been doing the last couple of days.

Video: mpeg1 and mpeg2 files are playing but you have to enable FPS display, if you don't the image won't get updated but the sound still works
If you don't enable FPS, you can still get a jittery playback by pressing pause/play, image will freeze when the controls disappears.
Here are the ffmpeg commands I used to generate the mpeg1 and mpeg2 video files.
mpeg1: ffmpeg.exe -i "RC-s8e1.mp4" -s 160x120 -vcodec mpeg1video -ar 44100 -acodec mp2 c:\RC-s8e1.mpg
mpeg2: ffmpeg.exe -i "RC-s8e1.mp4" -b 3000 -s 160x120 -vcodec mpeg2video -ar 44100 -acodec mp2 c:\RC-s8e1-2.mpg

Doom: I've put the rockbox.wad doom.wad doom2.wad, tried both with the same result, screen will freeze on the rockbox menu and then you have to hold the power button to turn off/on the unit.

Mod files (tracker music): I've had mixed results, .mod extension seems to be working fine, I haven't had any "new" issues with this player. Back on my Sansa unit I noticed that the total time and elapsed time were wrong and the song wil just loop forever, you had to manually press next to go to the next song, seems to be a general issue with rockbox.
XM files don't seem to be working, I get this message "Failure loading sampleinfo"
IT and S3M opens in a different player, if you try to quit it will bring a segmentation fault. If you let it go on it will go to the next song automatically but will eventually crash, with a segmentation fault, after a couple of songs.

Midi: some files work, some don't, I haven't done a lot of testing but I noticed that if the midi file has a lot of tracks, it triggers a segmentation fault. I had more or less the same results with my Sansa player.

Game music: I've tried NES, SNES, MegaDrive (genesis), Sega Master without any problems.

I tried to connect to the unit with ADB, after installing the driver (manually) I was able to start a shell. I am no ADB expert, used it twice before, the display seemed weird, here is a sample output of the command 'ls'
←[1;34mbin←[0m       ←[1;34metc←[0m       ←[1;32minit←[0m

Other "problems" reported on this thread:
Static/click sound: I haven't noticed it with while using my cheap KOSS earbuds or my "higher end" Beyer Dynamic BT 770 80ohm
lcd screen on/off: I can still see the screen with the backlit off, but you need a good light source to notice it. tried the echo 1, echo 0 command, I can still see it. I don't believe it's a real issue though.

Seems like a long post, I joined the forum 2 days ago to hopefully help the developers.

I was overwhelmed with joy when I found out that there was support for new players.
I would like to give my eternal gratitude to wodz for continuing his work on this player.

Cheers !

I just noticed that yes under a good light source and by tilting the player, one can see the icons and everything on the screen, I wonder if this is costing battery life?

I'm getting crashes when trying to build my initial database using a 128gb microsd (around 16,000 songs). I tried scanning individual folders but one of the bigger folders crashed just by itself. Is there a work around for this?

I just double-checked on mine -- and I was wrong, I can see it too on my Rocker.    The LCD being powered up (and updated) is definitely costing battery life.  Just how much, who knows -- but the backlight is probably far more likely.

Unfortunately it doesn't look like AGPTek's Linux kernel doesn't properly implement LCD power management -- the hook is there, but trying to enable it causes the LCD to stop updating forever, and _still_ doesn't power the display down.  Bah.

EDIT:  The original firmware seems to be able to power down the LCD entirely.  (Or perhaps it's simply blanking it and we can't tell the difference..)

What kind of battery life are people getting? I love having Rockbox on a new player, but I am getting pretty poor battery life — just a few hours after recharging. And it won't play when plugged in, as mentioned before.

[Duceboia]

My play when plugged in..  If I keep a button pressed when inserting the charger.
Not great endurance, I believe I never obtained more than 5-6 hours of use from a single charge ( with little interaction and display use or the situation is much worse).

[metroid2010]

Is there a manual for rockbox on this device? I could not find it in here, and I am not familiar enough with the project to know which other player's manual to take as reference

[crdaley]

FS#12878 seems to have creeped in to this port.  Using a theme that doesn't display album art is a work around for now.

I'm getting 6 hours of continuous playback (Bluetooth off) with Rockbox and 8 hours with the original firmware.
I hope that issue with the LCD being always powered up will be fixed sometime, and we'll see improved battery life with Rockbox.

I have a few questions to those experiencing always visible lcd content:
1) Does it occur in original firmware as well?
2) In rockbox does it update screen or is static when blanked?
3) Which version of the player do you have?

Anyway I wouldn't expect huge power savings. Vast majority of the power lcd consumes is backlight.

[LostEchoes]

Hi there.

I have the (v2) version of the Rocker with the slightly rounded edges.
Firmware version 1.2
The visible LCD content seems more like a burn in on the screen (but it's not an actual burn in). It does not occur with the original firmware.
I'm not sure I understand the 2nd question, though.

No.

It's not static. I can see song progress (time left, time played is updated)

3) Which version of the player do you have?
Benjie T6

I believe all players are affected. I myself noticed it only when I saw complaint and made sorrow inspection under different angles.

Got an AGPtek Rocker cheap-ish on eBay, installed Rockbox, and all is well so far. I'll see how long the battery lasts. I forgot to check if the LCD screen still displays when the player sleeps, I'll try to remember next time.
I was concerned about the 10s delay to launch Rockbox, but you can press the play button to skip, so that's alright.

I have the screen always on too.

1) no. If I shine a LED torch on the screen like in 2) the screen is definitely blanked
2) it updates: if I shine a LED torch on the screen, I can clearly see the time progressing
